Cermark spitfire,Powered mine with a g26 flies it great.Only problems i had wth the plane.Wanted to nose over while taxing.Solution which took care of problem was move the up sized 24 ounce gas tank 2 inches back,replace with larger wheels and replace with smaller tail wheel.with the stock air system had the pressure filling valve inside part fall out during flight lost all pressure thanks for spring down retracts.Replaced filler valve with robart works great.120 0s fs not enough power.g26 fit great just take off back plate.Best spitefire i have flown.
