av8tor1977, How does the GSP Katana 72" fly with the 23.6 conversion engine? Is there any need to modify the firewall to get this engine to work? Can you bolt it straight to the firewall and have the proper distance to fit the cowl on? And how about the CG? was there a need to add a lot of tail weight do to the weight of the gas engine on the business end?

There are lots of planes that can use a good 25cc engine. Like I said in the earlier post; anything with about 1000 square inches of wing or more, and preferably weighing less than 13 lbs.
"PHOENIX" my own design. 10 lbs. 1000 square inches wing, Homelite 25cc
Giant Scale Planes "KATANA 72". 12 lbs. 992 square inches wing, Echo/Kioritz 23.6cc
Hangar 9 "ULTRA LITE STICK 120". 11.5 lbs. (with smoke system) 1150? square inches wing, Homelite 30cc
Great Planes "FOKKER TRIPLANE". 10 lbs. 1312 square inches wing, Echo/Kioritz 23.6cc
All are very aerobatic.
