RE: Engine of Aurora 25
I use the Webra Speed 35 AERO #1023 with the Hatori manifold specifically made for the Aurora 25 and Hatori quiet pipe. Converted it to Spring Air retracts (main gear only). It seems to like the APC 10-5 prop!
Needless to say, it sure stands out among the current 3D style planes at the field...(wink)
