I went out to try to make some progress on a 1/2a project I started a couple of years ago and got side tracked again.
The first two photos are of a project thrown to gether using a wing from a foam glider. This is the fourth project for that wing. First was the original glider, then a couple of rubber powered projects, and now this. I'm a little shy to fly it because it has no timer and that motor will make good power for 1-2 minutes on a full charge and then kinda pull for a minute or two after that then it may actually be more of a brake. If it flops it flops. If it works how far will it go?
The second two pictures are of a Gulliows Cessna 180 that has really amazed me. I did go to the trouble to build it light. I ended up "trussing" the wing joints with news print after several wing disconnections. I also finally decided to leave an "access port" near the rear rubber band connection after replacing several rubber bands. I ran out of good rubber a while back and have been using some cheap rubber bands from an office supply place. You may notice the trim tab I put on one wing. I tweak it to make the plane fly in circles so I don't have to go so far to get it.

If it works how far will it go? OUT OF SIGHT! LL~ LL~ LL~
I am not into free flight but electronic timers should be easy to come by. Also I have an old KSB timer, 5 - 30 seconds, that could be modified to flip a switch. I would use a Radio Shack switch such as:
SPDT Switch Without Roller
Model: 275-016 | Catalog #: 275-016
This SPDT changeover switch is rated 5 amps at 250VAC and has a body size of 3/4x1/4x3/8".
The timer is old but it still works. If you want it it yours. Email me.
