July Bomb Drop Report

Overall I’d say it was a very fun event, everyone was having fun. We were able to hold a meeting, have an event, and still not tie up the runway for too long from general flying. 

Jim Bonnardel Explaining

 

There was a large number of club members watching the 11 entrants battle it out by dropping bombs (14mm nuts)  in a single round competition.

Bombs

 

We saw all levels of pilots step up to the plate with virtually every style of airplane.  Everything from a vintage “Crackle” flown by Ray Faulks, to a pair of Radians flown by Bob Stinson and Vince Gonsowski.

We had warbirds represented with a ME109 by Dennis B, a Wildcat flown by Neil Harland. Bob Anson did very well with his twin Multiplex, I think it is an Islander.

Tim Attaway flew his float-destined Mentor, while Steve Dente, Mike Eberle, Bob Mosely and myself flew foamies.   Everyone with foamies was flying something from DW except me, I had my 2 Dog Yak.

Jim's Release

 

We started with three drops onto the bullseye target used during Electroglide. The scoring was reversed, so the outermost band yielded the largest point value of 30. Ray Faulks quickly stepped up and was the first pilot up,  and promptly dorked his plane in busting the nose off ( a DW foamie). He had another plane with him, so we let him continue with his vintage Crackle.

Rays Drop Pattern

 

The action continued without any more fatalities of aircraft and all of the pilots doing pretty darn well dropping the bombs via a handful of different methods.  The radians were looping to drop the nut,  warbirds were doing both loops and dives,  and the foamies  were also doing all types of lunatic acrobatics to try to shake off the bomb.

Nice Catch Jim!  Is the tail supposed to look like that?

 

Tim Attaway must have made 6 different loops, rolls and other before he was finally able to unload the G forces that hold the bomb on. Seems that the Mentor had a magnetic personality and didnt want to let go!. Pilot skill in other areas did not immediately transfer to this fun style event, as the IMAC guys werent doing any better than anyone else.  With the reverse scoring and everyone having to drop the same way (a change in flight path), the event did not have any clear dominating airplane, or pilot.   Although it did help to be a good 3D pilot as that method of low and slow acrobatic drop did manage to win the event.

The Dente Drop

 

The Eberle Roll

 

Taking home the first place DHW Certificate for $60 was Steve Dente with 65 points. 2, 30 point drops and one for 5. 

Steve D. Awarded First Place

 

Next with 55 Points was Mike Eberle and a cert for $40.

Mike E Award

 

There was a tie for 3rd place, where Bob Anson and Bob Mosley were both at 40 points.  The Bob’s did a single drop to bullseye where Bob Mosley came out ahead and got the $20 cert.

Bob M. Shared Third Place with Bob A.

 

After the drop for points, everyone got a drop to bullseye for a bonus prize. Distance from center was measured via the 12″ NewBalance ruler (my shoe),  and with the closest drop to center at 5.25, was Mike Eberle.  Mike won a real nice meter/wattmeter/balancer/gauge device that was 
donated by John from Discount Hobby Warehouse http:/www.discounthobbywarehouse.com.  Its a nice item that we all can use.

After the bombs stopped dropping, and the prizes were all handed out, my wife Julie served up 12 feet of subway sandwiches to the membership.  I dont think anyone was unhappy about lunch!  A little chow, a little more camaraderie, and a little more general flying wrapped up Saturday, July 30th 2011.  We had a great turnout at the field and got about 30 folks fed for lunch. My personal thanks to all the members that came out to act like a fool with me,  letting our nuts hang out , thanks to John at Discount Hobby Warehouse for the discount on the cert’s and bonus prize, and to the club council who approves and supports the events we get to have each month.

The Next Big Thing-Step 8

So now I turn on the transmitter. Then the reciever. And………….

IT”S ALIVE!

the little LED lights blink the correct codes! Hallahluyah!  I am actually pretty excited.
I am not a failure, I did everything right. Its’ just that Scorpion Commander  ESC’s are not suited for
multicopter use. For airplane use, they are excellent .
But, they just don’t speak Italian and there ya go.

So the tricopter is armed and sitting there  in the grass ready to go, LED’s blinking and everything.
Because multicopters are,as a group,by definition, a multiple bladed blender, capable of 3-D carnage ,
I put on safety glasses! Because multicopters  are
by  definition, kinda scary what with the whirling blades TMES the number of motors, there is a safety routine
you must follow prior to arming the vehicle.

1: turn on the transmitter. Set throttle to low, trim 0.

2: plug in tricopter battery.

3. Pull throttle stick full aft and maximum right for 3 seconds.

The tricopter comes to life!
It just sits there with the motors at idle speed, LED’s bliking, awaiting your commands.

So, I take the sticks and give it 1/4 throttle to get it to lift off. Wrong answer!
This thing takes off like a rocket!. I cut the throttle and bring it back to the
backyard and “settle” it into the grass.

So between 1/8 and 1/4 throttle this thing goes from idle to suborbital !

Yeah baby! Thats what I’m talk’n about. Too much power!

Well I crashed it ( gently) and all’s I have to say is:  WOW.
( easy fix.less than 2 bux 4 parts)
Next fix is throttle respnse.
(  a generous dose of throttle expo and it should be good to go.)

The critera set forth in the first installment for easy reparibility was tested.
Two bent aluminum tube arms.
total: $ 2.15 .

If I was not writing this installment, I would flying. So now I am going to
sign off and get some flying in!

Next month:
Flight Trimming.

Electroglide Report from 8/20/2011

 

Bob Anson led the charge to altitude showing everyone where the elevator was,  and in the first round all the pilots except Tom Erikson had flights over 7 minutes.  Tom must have missed the elevator,  which was fitting,  because out of character,  he missed the target on landing netting a low time, and zero landing points.  Everyone else was hitting the target with deadly accuracy, Fred & Bob @ 30,  Terry @ 20 landing points. Bob had to dive to the field, and ‘haul butt’ home to be under time,  but he nailed it with a 9:55 time.  AWESOME.

Round 2 was even better.  Longer flights by the group, good landings, EVERYONE except Tom got 30 landing points!  Tom was so close with 20.

Round 3 again netted long run times, and Bob racing down to beat the clock at 9:39, but he missed the target for zero landing points, giving the rest of the pack some room to catch up.

Round 4 someone flipped a switch.  The lift was GONE. 5:53 was the longest flight (Bob came last last early)  and landing points were hard to come by. Bob was the only one to get landing points (20) so that made up for his loss in round 3.

Results From : Radian 4th place w/171 Fred Daugherty, 3rd w/177 Tom Erickson, 2nd w/182. Terry Thomann, and the winner was Bob Anson w/293.

In Summary,  we reaffirmed that Electroglide is not hampered by a 20 second motor run,  and that we can have an Electroglide and IMAC events co-exist on the same day without impact.  Electroglide is getting done in about 45 minutes from start to end,  and that has a very low impact on other flight operations.  Leaving the target in its current westward location,  keeps the electrogliders at one end of the field so IMAC pilots can show up, and set up down on the east end. That seems to work very nicely versus having the target at the runway ‘show center’ like it was before the field was moved east.   I would like to remind everyone to stay current on the website at https://www.sefsd.org as well as the club Facebook Page to know the calendar.  Don’t let weather fool you here in San Diego.  We have a real nice lift generator, just to the west, that big, black parking lot. with our prevailing wind from the west,  that column of warm air is blowing our way nearly all the time. August was proof that weather that looks like crud, can have flights that take the clock to the end.

Carl’s Report from Germany

F5B Nose

I haven’t enjoyed a pulsjet up close since I flew control line,  when three of us went home burned one day.  That was at 15 years old,  then came motorcycles,  women,  spearfishing and finally clean electric airplanes.  Watching them,  with their nitro dragster like sound,  from behind the fence was worth while though.

Yours,  Carl

Here are some pics sent to the editor by Ray Fulks.  Apparently there was a float fly recently.  Don’t know when.  Your editor has tried since the first of the year to find out when these events are held, so it can be published, but no one returns his emails.  If any of you know anything about when they are held, plese let your editor know.  If it is supposed to be a secret, let him know that as well.  Thanks.
