Today I had a 1st flight on a Brodak Cosmic Wind  57.5 "WS(Kit CLB-101). The plane is electric powered. Motor is the Arrowind 3526-05 Kv685. ESC is Castle Edge Lite 50. As far as the battery went I used what I had on hand a 4S 2700 25C.The RTF weight was 6lbs6oz. I controlled the throttle using a Hitech Rx and Tx 2.4. The prop was a Zinger 13x6. I used what I had on hand for lines, .018 lines at 65' center to center with an old EZ Just large handle.

Got out to the field late in the afternoon with sun directly in your eyes,temperatures in the 30s (it's cold dammit!) After setting neutral in the handle I was ready to go.

I decided that it was probably best to take off at full throttle with a pal holding her for launch.

She took off very nicely but after a few laps I noticed she was "hunting" a bit in level flight.The speed of the plane felt "just right" not too fast with power for climbing. I thought that when I cut the throttle she would fall like a stone, but she comfortably cruised at 1/2 throttle. I eased off the throttle for landing and she settled in very nicely. I'll keep you posted with some pics and more flight reports.....PhillySkip

Fred I simply held the Tx in my left hand and operated the throttle with my thumb. I'll add more lead to the nose to see if that helps with the hunting.Thanks for the invite,but don't think i can get out to St Louis .I will try to get it to Brodaks though. If the weather is nice tomorrow I'll get in a few more test flights.

glad to hear the hunting is gone, have you considered coming to the Nats in July? Model looks great.

facebook video looks good, in competition you will want to sit in one position with the engine at idle and then throttle up to full power to get maximum points on the takeoff run. But to be fair the formula one racing planes did a race horse start but they all had throttle control during takeoff. The judges will be expecting to see a throttled takeoff from idle even though is a formula one race plane. I looks likes it tracks well.

Pick your options before you get to the Brodak contest and practice the flight before you get there. Throttle control can be listed as an option.

The single engine airplanes without flaps typically do these options, and remember to put together a documentation package

1) Touch
2) Go
3) 45 degree flight
4) Missed approach
5) Taxi
6) throttle control

Looking good

  When competing in the time period of the Cosmic Wind, it was common to have some one holding the plan back at the tail since these things hd such tiny wheels and brakes. They would have the thottle wide open until the flag dropped. I ALWAYS wanted to be that guy! I got to sort of do that when I got to crew Chris McMillin's Pitts Special when he flew Sport Biplane at the 1999 Reno Air Races. They have a race horse start by rows 3 or 4 across, at 10 second intervals. They are allowed to have some one hold the tail of the airplane down while doing run ups and while idling to help keep the brakes from heating up, until one minute before the lag drops for the first race. I got to be THAT guy and and it was the the first of two times in my life I served as professional dead weight! I'll tell you about the other one some time!. I am forever grateful to Chris for arranging for me to crew his airplane that weekend.  It fulfilled one of my childhood dreams, to work on airplanes in the pits at Reno!

Realistic or not, WWI fighters & some racers didn't have brakes or even throttles, but dead stop before takeoff and after landing is required to get full marks.
Lots of planes couldn't taxi, but rather just cut the engine & bounced to a stop.  The taxi lap and smooth landing are still part of the game.

Is a fighter or aerobatic plane that can't do aerobatics "realistic"?

It was fun. I'd never flown a control line "scale" model. The use of the hand held Tx instead of dealing with 3 lines made it easy. I've got to get a few battery packs so I can get out there and really do some flying. During all flights I was using packs I had borrowed from some of the R/C guys at the field. I'm certain that this plane would fly great on a large Glow mill controlling the throttle with a servo,Rx and small battery instead of an ESC. As you can see in the photos I let Banjock fly it as well. He liked it,but thought it could use a slightly smaller handle........PhillySkip

Thanks for sharing,very nice video!

Watching the video makes me think I will have to pull the 109 out of the rafters and clean it up.  It has only been in one contest and think I could have placed if the engine shut down worked.  But I was having fun.

How did you get that?   I've lost count of how long ago I got rid of that kit.   Just looked at the 109 up in the rafters and I have the radio for throttle control.   Probably have to soak the old Fox 40 to get it running again.

And Fred watched the video again of the B-29.   Might have to convert Hutches B-25 even though it has stunt air foil.
