Tip for slightly quieter exhaust

[Gustav]

I just fitted a Dynamite exhaust deflector(little silicone hose to deflect the messy stuff) but i noticed it affected the sound quite significantly.

It's alot quieter at idle and whilst not significantly quiter at high rpm, it does seem to take the edge off the noise and sounds less harsh.The sound seems to echo a little less and so doesn't travel as far.(not so important seeing as my nearest neighbour is over a mile away.)

It didn't seem to affect performance at all,in fact this Sirio 27R seems to gain power with each tank but it is still loosening up.Just coming up to 1 gallon but not bad going seeing as i've been running it less than a week.

I have to say this engine is superb,definately the best i've used by a million miles.I was totally fed up with nitro before trying this engine and had sworn to convert everything to brushless but now i'll be keeping one as nitro.This engine is so nice.

Not all big blocks are the same.Before you give up on nitro, give a Sirio a try.
