Just have to work quickly with it though on the big areas. I haven't had any trouble with them holding either. Even in a nose in at about a 45 degree angle. (lost signal.) Had to replace both motor shafts and reinforce 1 landing gear with carbon fiber rod. No other damage.

Bomb drop!

I have figured out a way to drop bombs without a servo from your DC-3 All you need is a rubber band, a popsicle stick, an easter egg, some toothpicks, a straw and some flour.
1. Glue the straw to the middle of the popsicle stick(Refer to picture below)
2. bond the rubber band to the popsicle stick(Refer to picture below)
3. cut a tooth pick in half and then tape or hot glue it to the front of the easter egg. (Refer to picture below)
4. Wrap the rubber band around the front of the fuselage and connect the band to the popsicle stick (Refer to picture below)
5. Fill the easter egg with Flour
6. When dropping the bomb climb to a desired alltitude kill your throttle and put the plane into a dive.(Refer to video below)

I hope you enjoy this idea it took me a while to think of it but it works very well and there is nothing better than a satisfying explosion. (The idea described above does not go against AMA rules)

Thank you I spent a lot of time on the idea and it can also be used on different airplanes. Although I can not think of any way to drop a parachute from the plane. Any ideas guys?

Maybe set it up so that when you pull enough negative g's a drogue deploys, and it then pulls off a loosely attached chute.

I've seen some bomb drop and parachute drops via a spare servo and a rubber band. Seemed to work pretty well, but I haven't actually tried it myself.

Been thinking about doing this with my C-47 and dropping about 30 paratroopers at once...that would look cool as they all floated down, one after the other!



(P.S. Looks like "your" idea has actually been done before: http://www.ehow.com/how_5660897_make...rop-bombs.html )

Me and my buddies have made servo activated drops on other more suitable platforms than the DC 3 and will share vids later. Nice set up you got there Schroedr4

That's odd I did not know anyone had the same idea I had. I would have done a servo extension in the first place but I got the ready to fly verison and only have a 4 channel radio.

You could use one of the empty holes in one of your existing servo arms.

Maybe the rudder,, you don't use that too much except on take off where you use a lot of right rudder. You could use it on the left rudder and be all good.

Yeah, just set up the release at full throw. In the past I've used full up elevator for release.

Here is the drop from the Big Bird. The payload (stuffed bear wearing a parachute) is the orange box under the wing.

I also made the parachute. my next one is going to be much bigger to be able to see it better once its dropped from the plane (and of course to be able to see on on video).

Hey Schroeder4 the above post is to answer (I hope) your question. The box could be made shallower to fit under the stubby landing gear of the DC-3. Good luck.
