...The route I plan on taking is purchasing a venturii, needle valve assembly, a few head shims from Stuka Stunt Works and converting the engine myself without any machine work and seeing how that runs. I'm sure that at this stage of the game it will meet my expectations since I'm fairly new at this control line stuff. If I discover that I'm unsatisfied with it I'll just purchase a Brodak 40 or similar since in the long run that would be cheaper; considering in the cost of the engine plus the additional $65 for machine work and additional cost for the parts plus shipping. If anyone has a source besides Tower Hobbies where I can purchase the needed parts, please let me know. It would be greatly appreciated.

Thanks again,
Maurice

Maurice,

You will probably be satisfied with it as-is. If later you feel the need to alter the engine, consider installing a LA .40 piston/cylinder. On the LA, they eliminated the baffle port, probably as a cost reduction. I believe it is a drop-in fit.

Good luck.

George
