SEFSD FPV Guidelines


1) An FPV-equipped model must be flown by two AMA members utilizing a buddy-box system. The pilot in command must be on the primary transmitter, maintain visual contact with the FPV aircraft, and be prepared to assume immediate control in the event of a problem, with the secondary pilot flying FPV.
2) The operational range of the model is limited to the pilot in command’s visual line of sight as defined in the Official AMA National Model Aircraft Safety Code (see Radio Control, item 9) and not by the FPV video.
3) The flight path of model operations shall be limited to the designated flying site and approved overfly area.(map is located on frequency board)
4) The model weight and speed shall be limited to a maximum of 10 pounds and 60 miles per hour.
5) Maximum operation height is 400 feet. If manned aircraft approaches the area the FPV model will descend to 100 feet.
6) Aircraft fitted with autopilots for autonomous operation are NOT to be flown at the SEFSD site.
7) People who wish to operate an FPV model under the above guidelines must contact a member of the board and arrange a meeting to include the model so that safety and operational rules can be discussed.

Dual Control Instruction Manual

By John Forrester

Please download the short manual for those using dual-control for instructing pilots of radio-control model aircraft.

Whatever task you are learning, it helps to learn from others who have successfully done it before. Learning to fly a radio-control aircraft is just such a task, but even more complicated is teaching someone else how to fly. John Forester has written up his method of instruction so that any other pilot who is beginning to instruct, or who wants to see how other instructors teach flying, can read and learn from it.

Tucson Shootout 2011 Report


Every competitor gets to visit the prize table in turn and 30 plus sponsors led by Desert Aircraft insure each pilot getting a prize of at least $300 value.  The five days of TAS were marvelous in weather but more importantly in organization led by Dave Johnson’s Desert Aircraft team of Tony Russo, Steve Richardson, Brian Howard, Anna Woods, Bob Sadler (mouth of the South).  Fred Midget from Higher Plane recorded the highlights which he offered for viewing with a Flight Pass.  Many dedicated judges from across the country led by IMAC president Wayne Matthews came together with TIMPA,the host club,  plus the aforementioned talent …..and then add to that nearly 70 happy, grateful, friendly Scale Precision  (IMAC) contestants and you have the best Tucson Aerobatic Shootout I have ever been to….thanks everyone.

The SEFSD was represented by Dr. Ray Fulks flying Sportsman class for the second year in a row and improved his results to finish 10th out of 15 in that class.  Tim Attaway finished 10th also in the Unlimited class and another member, Steve Nelson finished in 9th place in Unlimited.  We had a terrific time at the TAS and look forward to the next one in 2012.

Old Time Enduro Contest

By Wayne Walker


Old Time Enduro Contest Nov. 19th at Rabbit Dry Lake

Just like the old California Enduro contest of the ‘90’s! Except of course it will be better!

Closed course on the Dry Lake, Triangle of 3-5 miles so there’s no CHP to worry about, 4 hour window to do your run or runs, 10 AM-2 PM. Electric and Solar only, one flight per battery charge. Unlimited tries during the 4 hour window. Scoring of distance is by GPS carried in the plane, Remote/FPV Piloting is allowed.

Pot Luck BBQ afterwards with maybe even some awards.

See the RCG thread at

This author is putting together a 3.5 meter sailplane with a Neu motor and at least 9.5AH of cells with video downlink and GPS logging.

Rumors are that one club member has a SIG Senior that can hold a similar battery load.

Update as of 11/6/11:  Well, with rain tonight at Hesperia and 3 days worth next weekend, I think I’ll postpone till SPRING 2012….

The Next Big Thing-Step 10


See that bear?  Yes, THAT is the arrow shaft I am using for this tricopter !
Honestly, this is THE place to get graphite arrow shafts of ANY type. Just to
see this place and the indoor range and the trophies EVERYWHERE  is worth
the drive! But, I digress…

I have now made a new airframe with flight proven electronics. It is almost like the
first airframe although with modifications based upon “experience” .

The first task is a more robust tail servo mechanism based upon AlexinParis’ quick and dirty concept.
The helicopter blade holder is also just too fragile


This is actually very quick to fabricate and is of very low friction. The pieces of tube that are
wrapped with thread are just extra graphite tube cut-offs. The thread is just button thread
cyano’d on. The trick is, I used some 1/4″ polyethylene water tubing jammed into the graphite
tube cut-offs. I then drilled out the center of the green tubing to make a nice bushing for the aluminum tube
(that holds the motor mount) to pivot on.  The motor mount is made of plywood and while it is hard to
see in the picture, it has some fiberglass cloth re-inforcing the mounting to the aluminum tube pivot
that rides on plastic bushings that cost 1/4 cent. The servo mount is also fiberglass re-inforced to
the graphite shaft. This works really well, no slop, no friction, light weight, easy, cheap, fast.
What more do you want? ( Did I hear some joker say, “for someone else to do it”  ? )
Check out the undermount servo. Totally covered by the motor, no drag.


This is slick and light and after all is said and done, I don’t think I would do it like this again.
I mean look at it. Even though I am going to put a bumper on it, it IS vulnerable to a hit.
You have to remember that the airflow into and out of a propeller is pretty much  80% of the
flow is through the outside 20% of the propellers’ span.  So mounting the servo on TOP of
the boom next to the motor would probably have a minimal impact on the total lift and a BIG
improvement on the rugged-ness  ( is that a word?) of the airframe. Hey, next time. In the mean time
here are some more pictures of my tail servo set-up.




Next month we will delve into the upgraded power distribution network .

Stay tuned!

Electroglide Report from 10/15/2011


Grey skies were not the concern of the day, even though we had them.  The early concern was fog.  The overcast was nipping at the top of the Sea World tower and we did not have visual of the upper half of Mt. Soledad. Pilot meeting advise was that at anytime you can come out of power during the climb if you are nipping at the base of the marine layer.  At the end of the first launch, it was evident that we were not going to have any problems as the layer was starting its retreat for the day.

All 4 launches were able to get done without keeping the EMAC guys from doing any flying.  We were done and they didn’t begin for another 40 minutes after we finished.  Its nice to see different groups getting what they want from the field on the same day without schedule conflicts.   We did have a couple of incidents of note, both in round 2.   John F. lost control and put his plane into the pit area,  and Carl C lost visual of his plane, and put his in downwind. Carl had crashed, but he was actually watching another airplane and did not realize he was not flying the plane until the one he was watching had made its commitment to land, and he got visual that it was not his plane.  Both ships were fine to continue on (and did), but this is a reminder that we as pilots, are responsible for the safe operation of our airplanes.  If you are having trouble and are headed into the pit area, you need to sound off, and alert the other pilots of the problem.  There is lots of time to shout out “HEADS UP”  or “LOOKOUT” or “INCOMING”.  Any audible clue you can give  that there is a problem is greatly appreciated by all.  

Carl’s plane was returned to him in time to get to the line for the 3rd launch,  which is where he started getting points.  Stay in visual contact with your airplane and if at any time you are not sure, do an abrupt movement like a quick pull up, or a rudder wag  that will ensure you are looking at, and flying the correct pane.

I personally again went too long for flight #1,  flying 10 minutes, 7 seconds for a ZERO ZERO.  The first flight is where everyone got their longest times of the day,  so for me,  missing that score hurt badly. Bob S and Norm A had 9:53 and 20 points for round 1.  Those were the marks to beat.  I was the last one up, but went too long,   I really got to learn to come in sooner!

The rounds got progressively shorter with the lift bubble turning into a sink hole.  Across the board averages were 9 minutes for round 1,  7 minutes for round 2,  5 minutes for round 3, and 3 minutes for round 4.  After the round 2 excitement, 3 and 4 were incident free.  Make note of the Radian scores for place finishes.  ALL ABOVE  240.  The bar is clearly set pretty high by the trusty Radian.   A great plane, with a dedicated pilot can clearly pull more than its own and perform with the best of them.

There was a new form in use today,  let me know if you liked it or hated it.   I will change the “Standard” class to read “Radian” class as that is what it is.

Let me know if there is any suggestion you have to the scoresheet as I only print enough for the expected group and can make changes at any time.


The Club Facebook shows the scores:


And the report is on the club website:


Placement Scores:

Easy Star Class:
1st Place           Terry McLean *      143
2nd Place          Carl Cox*               54  (only 2 rounds scored so not too bad for only 2)

Open Class
1st Place           Jim Shelton           216
2nd Place         Jim Bonnardel         189
3rd Place          John Forester         128

Standard (Radian) Class
1st Place           Norm Arndt           265   (make a note that had Norm not plowed into me at the bullseye round 2,  he would have skidded through the scoring markers!)
2nd Place         Bob Stinson            261
3rd Place          Tom Erickson          244


See you next month for more loitering.

Pylon Racing for October 2011


Thanks so much for a great season of fun and competition. Your dedication was on display today,  you were the Iron man of the day.  It was nice to meet other flyers, fly on other runways,  and enjoy some of the best low-stress racing ever brought to San Diego RC Pilots over the last several months as you are by far one of the best RC Ambassador’s around.

As evidenced the last race of the season,  this race series brings in new pilots all season long. Both Richard and I look forward to the next season and race day, until then I wanted to pass along a heartfelt thanks from one Paisan to another.

Warmest Regards,

Jim Bonnardel

The Fun Jet Lite Testbed


Easily bought,  easily built,  easy to fly and anything fits into it,  it came down to a Fun Jet being what I could get as a test bed economically.  Any motor with the smaller mounting screw circle(s) will fit in a Fun Jet,  swapping propulsion components takes minutes.  It’s thrust to weight requirements are so wide that anything that can physically be installed flies.  Further,  I have at least (5) high revving,  some never used,  motors weighing from 35 to 117 grams that either have to go into a (always a tight fit and easily destroyed) pylon racer or,  a Fun Jet.  And some more slower turnings from (17) to (100) grams for low velocity and quiet flight experiments.

I recently observed the flight of a really powerful Ultra Fun Jet at a foam airplane gathering,  like 6S LiPos and 800 Watts-in.  Although fast,  it wasn’t as impressive as I expected.  It’s an  X squared thing,  above a hundred and fifty miles an hour it doesn’t seem how much power you put to it,  it won’t go much faster.  And,  trying to impress the crowd,  the nose was broken off in front of us,  to sort of be glued back on  (crooked) right there at the field.

At first,  just looking at it,  the representatives of Multiplex (professional pilots included) weren’t all that impressed with the improvements to my Mini Mag,  even with the conversion to a bash plate nose with the motor behind the bulkhead,  “Sturmovik” armor and the notation “250th flight”,  it looks just about like a hundred thousand other Mini Mags,  abet with no landing gear.  Nobody else seems to have caught on to improving foam airplanes with fiberglass,  or folding props,  or higher cell counts,  or better motors,  or controllers that can be set for the correct lead.  After it took off straight up,  and just kind of drifted/careened/blasted all over the field for (30) minutes (on just one battery),  they all came over to find out “what do you have in that thing!?”.

That Mini Mag was then fitted with a 4S 1100 mAh (125) gram battery (Thanks NeuMotors,  I reconfigured those 3S ones you sold me),  (70) gram Hacker outrunner,  a Hacker motor controller that can be set for outrunner correct (20) degrees lead and a 10 inch Aero-Naut folding prop.  Vertical climb at a count of ten is higher then I can reliably estimate,  but about a thousand feet,  glide back down is a count of (170).  Weight,  added fiberglass included,  is about (750) grams.  It can fly at just above walking speed on up to being a slower pylon racer.  That is staggering performance,  it didn’t come cheap.

Although in truth an affordable Graupner (45) gram motor (may I recommend a Scorpions) on 3 or 4S with a (7to10) inch folding prop can be delightful too.  The (75) gram NeuMotors 1105 gave incredible mid to high speed performance,  but it was the low speed possible with the high quality outrunner and bigger prop that won out.  It turned out that (70) gram motors with their lesser requirements on battery capacity,  beat (100) gram motors on flexibility.

The Fun Jet Lite is going to fly even slower,  and faster,  at the down side of that pusher prop howl of fast combinations (a goal here is minimal noise) and the limitations of elevons.

This contribution is also to influence my future return to good status with the SEFSD,  and atonement for (Hey you Fool,  part of your airplane is missing.  Please tell me that dot way out over Shelter Island isn’t your airplane.  Oh no,  not another packing crate materials airplane.  Have you no respect for matching colors?  Even if you are wearing a tie,  you still have to have a shirt on and be upright to fly here.)  the older members suffered through,  while,  among others,  the Editor and Current President kept me flying when I have been almost,  but not quite,  completely broke.

Although in possession of a “stock” Fun Jet already,  it’s back in California,  and I’m in Recession Exile in Western Germany. At a big swap meet on the 9th of October 2011 (Sa.) at a moment when I was open to buy (and needed a ball point pen),  a dealer was selling off new Fun Jet kits including a bottle of CA,  and a pen,  for Euro39/$50.  No longer included here is the Speed 400 motor and prop.

The necessary pair of 6” extensions added Euro3,50/$5 to that.
