Hi Guys

Hoping someone can help,

I have an MD530 scale fuse for my Titan 50 mechanics, I have test flown the mechanics out of the fuse and all running fine

Now in the fuselage I have extended the muffler exhaust to exit the fuselage in the scale position using a large bore silicon pipe and I`m now getting a strange pulsing of the engine after a while in the air

The engine is a stock TT Pro-50H with stock TT muffler running techpower 16% fuel from Model Technics, After a while in the hover I get a drop in head speed and a puff of richer smoke out the exhaust it then instantly recovers but will then cycle the rich puff and drop in head speed !!!

I thought that perhaps oil was choking the muffler outlet inside the silicone pipe but this is all clear

So, what problems could this exhaust extension be causing me ??????

Any help appreciated

I don't run that motor but did the same thing with a Hyper and it ran just fine. I had to run it a tad richer and not put the back windows in so it got plenty of cooling but other than that, no problem.
