Edwin, I've got a Hitec Eclipse 7 transmitter, and usually use Berg 7 channel receivers. I've not got the cash to convert over to 2.4 gigglehurts yet.
I think the situation is pretty much like the EDF Jets. You don't want your wires or electronics anywhere near the fan unit. It creates RFI which can shoot down your airplane.
I did notice that there were two types, electronic ignition and the magneto you mentioned. I wonder which one is the easiest to start. I've read somewhere in the past few days that EI can be more difficult, but then, that was just one opinion.
I've noticed that those who fly the big aerobatic airplanes will push their prop into a particular position before flipping it. Sometimes they get it to catch the first time, but more often, especially when starting the motor for the first time, they spend a few minutes before the engine catches.
All I can do is read the owners manual like with all other rc gear to learn how to use it. Hopefully, any equipment from China will be better written than some of what I've gotten in the past.
I've heard of nyrods. Are they the Dubro things that have a white and red plastic tubing setup with metal hardware that screw into their ends? That sounds like it would be very good for the throttle control.
Gorish mentioned pull-pull setups on the tail feathers. The only thing I've done like that was with an electric powered Curtiss Jenny I had at one time. It sure was fiddley getting it all set up properly, bur after that, control was really good in the tail feathers. Of course, this was mostly built, and ARF, and the pull-pull lines were there waiting to be connected to the servos and control horns. This type of system would take a bit of thinking on my part to design, as it isn't part of the instructions on this kit.
The next time I am out at the field, and someone brings their bit 100+ inch wingspan Extra out, I will ask if I can watch and ask questions about what they are doing. Need to learn somehow.
