I´m not a electric man but the advice from Ivve Hallberg(the guy with the B17 on the video above) I bought the same setup to the Lanc,
https://www.hobbyking.com/hobbyking/...idProduct=2099 and speed controllers for those..
I dont know how much it weighs yet but it is light,thats for sure!
A guess would be 25 Lbs or somewhere around that.
The power is as far as i can tell more than enough,no aerobatics yet but i flies around on 50% throttle?
One thing I forgot to tell you,the rudder has little "response" (and in the air),taking off is with full right rudder,the tourqe is if not a problem,something to considder.
Two of my new props are contra rotating,this solved the problems with Ivves B17,the other way is in the manual:let the inner pair of engines rev up to full RPM before the outher...
And I´m going to mix the throttle with the rudder,I think this can be very useful in windy conditions..
