Mine flys great on a Webra 1.20 mounted sideways with a Perry pump and the tank over the CG. In fact , another flyer at our field liked how I mounted my engine sideways and did the same with his Saito 100 and now it doesn't have fuel running out the carb after fueling it up cause the carb is even with the tank outlet ( his tank is in the original location). I have Hitec 645MG's on ailerons and elevators and a 945 on rudder and a HS85MG mini servo on throttle. Have fun !
