Re: Helicopter Testing
I don't know, but even if they were allowed, would you want to use them? Think of the weight gain, even from plastic gears...

Re: Helicopter Testing
i have an idea that I'd like to test if I get enough time to build it and test it that I hope might work well and hopefully overcome the weight gain. But yeah, I thought about that when I thought about tandem rotors last year. But could someone explain how you could make one with 2 motors??

Re: Helicopter Testing
You're having difficulty with a a basic two-motor design? You must be really smart...
It's just like two motorsticsks connected together... kinda like this:
_ ' ' _
|__|
|__|
The vertical things are the motorsticks, and the horizontal dashes at the top represent the rotors. The two other horizontal lines (the longer ones) represent braces that connect the two motorsticks. (Ignore the two apostrophes) Of course, this is very very basic and probably not efficient in terms of weight. There is a picture of a tandem-rotor heli in the image gallery somewhere. Take a look sometime.

Re: Helicopter Testing
Oh wow ok I feel dumb. I've been imagining a tandem copter with only one motorstick going across horizontally which is why I couldn't figure out how people were going to use two.
And on a different note, would anyone be willing to post the rules for us that haven't had the luck of getting it yet?

Re: Helicopter Testing
I built a quick tandem heli today. Winding was tricky and precarious, but it was feasible. I used two separate motorsticks, and two 3/16 rubberbands. Three people would have made it easy, but I was able to get it done with two. It wasn't as bad as I had expected though!
