RE: Rocket Take Off RC Plane
Getting model rocks to go off at the same time is extremly hard, and how he managed to get such even fireing im not sure.
when you wired all the rocket ignitors togeather, did they all connect directly to the battery or togeather in a *string* of sorts?
they should all connect togeather at the battery for the most even firing, wiring anything in series or *string* or sorts allows one to get more voltage before the other, adding to the problem.
2X ignitors may also be needed per rocket, not everyone is made equell.
Something like this requires alot of trial and error, and infact if you watch mythbusters they did a episode or *myth* about a rocket powered swing, they could allmost never get both rockets to fire evenly. so obviously its a common problem, but fixable with enough effort.
as far as a remote firing, a servo could do it mechanicly by directly attaching 2 wires to complete the circut, there is probbly a way to do it without a servo directly but using the servo for a direct connection would make it simpler and just as effictive, i cant think of the correct RX powered switch at the moment but they exist.
