Hi/ I am a new member so treat me gently/ We have been flying elcetric,about5 yrs, we have flown general types,ie Wot 4s etc. now we are branching out to large scale and semi scale,airobatic types. we have been experimenting, with lipo flight batteries and have had some sucsess. we have aquired a large Tucano 70 inc span,complete with retracts, there are two separate flight batteries,but no receiver. what we need is where to plug in the two, obviously one is for the retracts,and one for the R/X. we have a large esc,so where do we put every thing??
