UGH !
I was flying my Raptor 50 today and WOW it was flying extreamly fast i could not belive it, seemed like a jacked up 90! But then came to a high hover around 40 ft and she just cut out. Now once before i left that line that goes to the muffler off and i noticed it was running very fast like today, and it was off after the crash so im guessing here.. Does that make the motor run fast and cut off after a while. Whats the deal with that line anyway, if it does make it run faster, what tweaks can be made with it,, can you restrick some of it somehow. As it was comming down it was doing a good auto and i though i had it made but around 10ft it dropped a little hard, my carbon blades were ok but smacked the boom, at least the blades were ok. Please tell me about auto's. When i seen this perfect auto happening i let off the stick a little cause i wanted to save some pitch but i think i lost head speed by doing so and thats why it dropped. I was a little above mid stick. Should a of kept it there than waited to get maybe5 ft then up stick???

Thanks

Obviously without the muffler pressure line to pressurize the tank and fuel flow, your fuel flow will be? LESS!

Lesser fuel per fuel/air mixture = lean run

No wonder you were getting insane powers

I think your engine should be fried dude. Open it up and have a look

ooh, I hope that motor is ok. Strange it was making a lot of smoke soon as i started it like it was rich. I just put the motor back in right before this flight and belive i put that line on. Theres a chance that it could of been pinched while putting the motor in though. Can the heli smoke a lot and be lean at the same time. >?

The motor seems like it sounds the same by just turnning it over with the starter . Should i just try and fire tommorow it up or take it apart ??

turn it over without the plug jsut to make sure you can. I would also replace the glo-plug if you havent already. I had a good auto when mine blew but it wouldnt turn over and then shaking it around i could hear a rattle. best of luck,
