RE: Radial engine in Top Flite Stinson Reliant SR9
I have not been able to find any info on the Seidel or Moki radials to see what they have available. It looks like with a cowl rework, that the Evolution E777 7 cyl engine will be the best fit in size and power for the Stinson. Hopefully, Horizon Hobbies will have one on display at the AMA Expo show next month in Ontario, Calif.
