Brad’s Corner for July/August 2017

Hi Folks!
I hope mid-summer is meeting your expectations. If your expectations have included heat, humidity, and crosswinds – it has been a spectacular month! Well, we knew it was coming, so all we can do is smile and wave. Some of us have been hiding in our air conditioned spaces, but I would like to throw a shout out to Tom, Tuan, and Brian who have been determinedly raising their proficiency in crosswind landings. Great job guys!
For my standard banging of the safety drum, I want to say thank you to the folks who are always on site with their fire extinguishers and ready to save us if things get out of hand. The entire outer field area is very dry and flammable. Please bring enough water to stay hydrated for your expected stay. You can re-fill empty bottles at the boat ramp if needed. Finally, it is not a bad idea to bring and use sunscreen this time of year. I saw Randy after a long Saturday, He looked like a red Papa Smurf…


Jim has been spraying the field to keep weeds down lately, Thank you for not trying to get extra points by seeing how close you can get to him ( Skip!! ) while he is around the edge of the runway. Thanks also to Dennis for countless hours weed whacking, and Tom and Chief for keeping growth down around the tables. We have had a couple years of use from the tables at the main runway, and we know they are starting to wear. Between now and the end of the year we will change out the worst of the tables to something closer to what was installed at the rotorplex last year. Please do not hurry the demise of the current tables by picking holes into them or striking them with hammers.
As a group comprised mostly of grown-ups, I have to ask you all to take the initiative if you see something unsafe. You do not have to wait to tell a board member, or wait for someone to handle it. Please step up and say something, if you need back-up – ask another member to join you and you can both have the discussion. Jim and I saw some VERY unsafe actions at the rotorplex a few weeks back, and both approached from different directions to have a few words. I am positive we would have had the same response if we were not on the BOD. Please join us in keeping everyone safe!
We had a pretty decent showing for the festivities on the 4th, the evening cooled off nicely and some of the fireworks were visible this year through the smoke which plagued us the last couple of years by drifting right at us. Thank you to the folks that stayed into the evening for not leaving piles of trash in the pit area.
My last conversation with Isabel puts us around 360 members for 2017. A bit behind last year, but still growing. Thanks to everyone that has been stepping up to invite new people to join the club. Steve, Randy, and Fred have been going out of their way to answer questions.
The monthly meeting/fun fly/lunch on SEFSD is coming up on 7/22. This is our summer bomb drop event and is a lot of fun, which can be had by all levels of flyers. If you can take off, go to an approximate minimum altitude, and make an approach, you can play!  And win prizes!  But don’t forget to watch your plane!!  When we do the summer bomb drop, we change up lunch a bit by ordering a couple of large subway sandwiches, which will be served by Jim and his wonderful wife Julie.

Bring brooms on Saturday. Most of you have noticed that the heat has not been friendly to the field. The clay has powdered in places and is mixed with sand. Before kicking off the fun fly event I would ask that folks bring a broom and we will spend 20-30 minutes sweeping the runway in preparation of Jim doing a 2 day mid-week dousing and rolling of the field. We want to get water down deep so the surface should last the remainder of the year. When Jim puts down the water, we will close the main runway to flying for 2 days so no one puts foot prints on it before it is dry.
See you Saturday and have fun!!



Electroglide Report for July 2017


The second launch had us all heading to the west, as high as we could get in the 20 seconds before motor shut off. The lift was there, brought to us by the breeze across Sea World. Flight times now jumped, the shortest time was Roger Ball’s 6:16, earning a maxed out 60 Lucky Dog points. Jim Bonnardel, flying the Radian Pro and Tom Erickson flying a standard Radian, battled it out towards the ten-minute time limit. Tom came in at 9:19 for first place, Jim a close second at 9:14 with a 20-point bonus landing. Really good flying guys. Scott Vance came in third at 7:53 with a 10-point landing. Dennis LaBerg also scored a 20-landing.

Can We Have a Club Chiropractor?


Third launch showed the lift was still available. I had a flight time of 9:29 plus a 20-point landing. Scott came in second with 9:02 with a 20-point landing. Dennis came in third at 8:30 with a 10-point landing. Fun stuff!


Jim Approach

The fourth and final launch was into a stronger breeze that seemed to be effecting the lift patterns. Flight times reflected this with Jim earning the longest flight at 6:37, also with a 20-point landing. Scott came in second at 6:02, I earned third place at 5:37. Roger also picked up a 20-point landing on this round.



Jim-It’s still sliding


Winners for the day: Jim Bonnardel, flying in the open class had a point total of 238. All the other aircraft flown were in the Radian class. I had the highest point total at 233. Scott Vance came in second at 224, Dennis LaBerg came in third at 202.


Jim Well

Jim-Well it’s Still Worth 10 Points


I would like to point out that in the first launch, I had the shortest flight at 3:36 which earned me the Lucky Dog award. That award which when added to a 20-point landing bonus gave me a competitive 64 points for the first round. One does not need to be able to fly their glider a long time. Points are awarded for flight time and the target landings. Because of the Lucky Dog award for the first aircraft back on the runway, the flight points are doubled. Park your airplane in the target circle and you can pick up an additional 10, 20 or 30 points.



Jim, Jeff, Roger & Tim Heading Up


Come join us next month, the third Saturday. It really is fun and it makes you a better pilot.


The August Electroglide will take place on the 19th. I will be on vacation but Scott Vance will be hosting the event.

An Unusual Sight in the Sky

By Robert Stinson


Dynavert 1


You may have seen this flying at the SEFSD field and wondered what it was.  Is it a real plane, did it really have a third motor on the tail?  The answer to both questions is yes!  The plane is the Canadair CL-84 Dynavert, developed for the Canadian Armed Forces in 1964.  Four were built, two still exist in museums.  In an age before “fly by wire” electronics, the design was truly visionary. Top speed was 321mph, certainly faster than the helicopters of its time. However, its uniqueness and the rapid pace of helicopter development kept it from being adopted operationally.


The model has two modes, hover and forward flight, both controlled by an onboard computer.  In hover, the two main motors provide lift and roll control while the tail motor, which rotates left and right, provides pitch and yaw control. Stability in transition to forward flight is handled by the computer. A big servo in the fuselage pivots the wing. In forward flight, the tail motor shuts down and control is by standard elevator, ailerons and rudder. The real plane did not tilt the tail motor, but achieved hover control via variable pitch propellers, and flaps and ailerons in the main propwash.


The Dynavert model sometimes gets mistaken for a V-22 Osprey, but the Dynavert preceded the Osprey by 40 years. One main difference is the CL-84 tilted the whole wing, while the Osprey only tilts the motor nacelles. This latter is a distinct advantage, as when the Dynavert wing is vertical it makes a great air dam! If the model is flown in a breeze, it sometimes has to tilt close to 45 degrees simply to keep stationary.

An example of the real one is on display at the Canada Aviation Museum in Ottowa.
