I been flying mine with a YS 110 for a while and it flys good. To help balance the model, I ran two Hitec hs-77 under the tail for the elevator, and a s9402 for a pull pull setup on the rudder. Reinforcing the fire wall is a must, my broke off when the engine backfire once. The plane hovers at less than half trottle, and will climb out of sight in seconds. For the price, its a great buy A+
