I can't stop obsessing about flying a ka50 havoc,I have downloaded card models and scaled them up to about 1/20 scale.I am looking at the century razor cx for the mechanics as this size might have a reasonable chance of flying outdoors in maybe even a slight breeze.I'm wondering how easy a brushless conversion would be,the motors are brushed 380's supplied by an independant speed controller.I've been looking at some of the images of the electrics and can't make out if the independant speed controller has 1 or 2 receiver leads going into it from the 3 in1 unit,the replacement brushless setups have two esc's so it needs 2 channels(motor and rudder I guess).I notice dealers in the USA sell mixer leads so you can still use a basic 4 channel tx receiver still needs 2 outputs I would have thought.Can anybody advise me
