First real flights a couple of days ago. A nice plane to fly and the sound of the twin engines is addictive. I'm using two 140w brushless motors and 18A ESCs, with a UBEC for the power to the Rx (AR500) and MA 7x4 props. On the meter I actually see nearly 170W at WOT out of each. She flies steady on around 1/2 throttle and glides for miles! A 5 min flight leaves a 2250 3S with around 3.93V per cell. Heres a piccy just prior to the second flight...  |

Very nice, will that fly on one motor?

Very nice, will that fly on one motor? Supposedly, as there's enough power, although I read that it's not easy. I guess I may find out one day  |

Is it possible to try it? i mean temporarily kill one motor mid flight & try to land it?
Just curous...

Some have put them on seperate ones and then mix throttle to rudder to help with turns. I'll have to wait till something goes wrong!  |

Well thats a coincidence! I bought two of these to learn to fly then got cold feet and decided that since I was learning alone maybe 3 channel would be better at first, hence the SuperCub!
Actually the one I bought fist is a TwinstarI, much repaired by the previous owner. Then I got crazy and bought a new TSII when they came out. I have flown neither yet but the Cub is getting me confident enough to give it a go! What I thought I might do first is refit the Cub with standard radio gear and go mode 2 so the rudder would be on the left stick so I could get used to it...anyone got any thoughts?
I will post some pictures at the weekend

once you have a mode 2 TX setup you are usually flying something with ailerons which are primary turning control surfaces and operate off the right stick. i only use rudder on my planes rarley to coordinate turns or just turn flat using mainly rudder and aileron to keep the plane level. until youre running an aileron setup keep the rudder on the right stick

Agree with Admiral on that. When I first swapped out the stock electrics I did what you are suggesting without ailerons. It resulted in me losing control pretty quickly as I'd not got used to using my left thumb to turn.
Once you fly the TSII (or any other aileron aircraft), you'll realise that rudder is not essential to turn.
There are a couple of options that you can do though to use a new radio with the cub (without ailerons):
1) If the radio is capable, mix the rudder into the right stick.
2) Connect rudder servo to the channel on the Rx for ailerons.
Both of these would require a bit of ground testing to ensure you get the correct reaction from the plane before commiting it to the air.
