Piper511, you doesn´t seem do to get that "CLINK" in the air like the others when their V7 goes all to he** you only get a carb full of fuel. empty it and you be fine.
But this is a serious subject, I', soo sick and tired to hear all the stories about V7 engines that go "KlinK" and "Klank" in the middle of the air.
You buy a brand new heli LMH 117, put some expensive electrics in it and the engine fail in the middle of the air, in best case you get away with some broken main blades and such but in the worst case.
You might have to get a new receiver, servos, main shaft, main blades, tail boom, tail rotor case and all kind of stuff.
LMH should really address this Flaw, cause I think is a REAL Flaw in their helicopter.
Sure it's great that they replace your engine without hardly any questions asked, but do they replace your electrics and other parts that breaks because of your engine gives up? and should they really have to replacy your Engine ?, I think not, I have flying planes over 10 years with engines standing right up and inverted and I can never blame the engine for crashing my modell.

LMH Please shape up and get some new other engine in your model, cause it's a really GOOD Heli to get inroduced in helis with.
