Greetings all,

Had a zoom for about 6 months and can now safely hover , bought reflex and been practicing.

Decided that it would be fun to have a go with a " big one " so got a century hawk with irvine 39 engine.

Thought I'd make it look a bit flash so added a musclepipe 2 from midland helicopters ( told them what engine etc ). It was nice and shiny

Paid my local model shop to check it out and set up throttle curve and pitch etc as this bit I have not got a clue

Anyway get it back ready to fly I'm told so off I go and try .

Get it started with a tiny bit of throttle , lots of smoke and get it to hover !

I,m a bit surprised that it takes 3/4 throttle and the engine is screaming But I hover it for about 5 minutes and then come off the throttle to land and guess what ??

The muscle pipe 2 explodes, no kidding there is huge bang and the back of the exhaust smashes into the floor where it lands and burns the ground with bits of the inside flying every where

Simple question really, what did I do wrong ?

I'd say the first place you went wrong was to get the model shop to set it up for you. IMO you'd have been much better to find a flying site and finding some kind soul there to help you set it up and test fly it for you. This way you get to see how to set it up and get explanations on why things are done a certain way. I'd go back to the shop and tell them what happened and ask them to test fly it with you watching. If they refuse, then chances are they probably don't know how.

You may have overfilled your fuel tank resulting in some overflow getting into the muffler where it could have pooled. A backfire resulted when the fuel ignited resulting in the loud bang and subsequent explosive force. This happened to me once on my Raptor 30 with a one piece muffler. Always make sure there is no fuel collected in the muffler.
