@EstebanCRC I haven't tried the 9x7.5. The group I race with specify the APC 9x6 prop so I've just been using it. My next order from APC will include that 9x7.5 though as I'd like to see just how fast that TT40 will go.
@jfinch84 Dude can you give me some advise? What do you think is the best way to break in this engine? It looks like every body does it diferent, but you really seems to know about this things. Thanks man, I´ll really apreciate it.
@EstebanCRC I broke this engine in using a 7x7 (or maybe it was a 7x6) APC prop with both head shims in. Run pretty rich for about 12 oz before starting to lean out. Then run a tank (~4 oz) with one of the shims removed. Then another tank with the last shim removed. Don't lean too much (adjust so the rpms jump ~300 or so if you pinch the fuel line. Then I just put on the 9x6 and ran. Don't know if that's the "right" way or not, but that's how I break in my engines.
@jfinch84 Hi Finch! A other question for you men! My engine comes with an extra o ring in the same bag with the Allen wrenches. I removed the needle valve to check but an other o ring is all ready installed there. the one in the bag is an spare o ring or I missing something important? Thanks man... I really appreciate your advises.
NICE plane, BEAUTIFUL mountains.

@EstebanCRC I don't remember if there was an extra o-ring or not. If the carb leaks fuel when you run it than it's missing the ring. Enjoy the plane!
