What plane is the GP123 for. Never owned one but from what if have read they are up there with power.Received a few goodies today, the new formers for the Bulldog and the GP 123. I compared the formers to the outline for width and height and they look spot on. The GP 123 looks pretty good, it came with NGK's so no throw a way's. I have some Bowman rings for it but I am not going to install them. I think it would be best to see how this thing runs before I go and void the warranty, who knows it may surprise me. And something I have yet to see from any other engine, they have included in the manual the torque for every bolt on this engine. Very cool!
It is going in the AJ Aircraft Laser 230, the Valach is fully broke in and needs to come out.What plane is the GP123 for. Never owned one but from what if have read they are up there with power.
They are interesting just pulled them out and checked them and brought them up to storage charge. At storage charge there was not one cell above 1.1 AR that is impressive. Will see how long they stay that way. It will be awhile need to build something for them.Are they the newer 90C ? If so let us know how you like 'em. I bet those would get my Avanti S to 120+ mph.
Best I got with the HRB 50C 5000's is 116 mph straight and level.
