Do a search on this section of the forum for LA.40. You will find that it is pretty similar, except for prop diameter. They don't have the good rep that the LA.46 has fro some reason. I have an LA.40 in my Dusty profile scale/stunt model, and have never had an unacceptable run with it. I have it on throttle for scale competition, and then for stunt contests, I pull the carb and install a venturi and spray bar and fly as normal. Plenty of power for the almost 50 ounce airplane. I think I have a .250 venturi from Russ Gifford in it and a three bladed 10-5 prop from Master Airscrew, SIG 10% Champion fuel, Glowdevil R/C long plug and tung muffler. I'll probably use another one in any future .40 size stunt projects.
Type at you later,
