Status: offline 		I picked a Sig Fazer over the weekend that had a MVVS .46 attached to it. I don't know much about these engines. I appears to have a long pipe attached to it instead of a muffler. Are these engines good?

Anybody have one or know much about these?

Thanks,
Troy

The long thing is a tuned pipe and gives you more power for more RPM or to swing a bigger prop.
If the engine is new you might think its a pig to run, but it needs a long run in period, dont worry about running it rich, it just takes ages for it to settle down, espicialy on bottom end, but once it is, they are lovery.

Status: offline 		Hello!
The MVVS engine is a good engine.
There is amuffler available for it if you wanr one anf two different tuned pipes,one made for rews from 10.000-14.000(No 3248) and the other made for rews between 16.000 and 24.000 rpm ( No 3246).
These pipes are realy cheap and cost only $17.00 each!
So if you have the No 3248 pipe which is apr 13cm long you have better use a 10x6-10x7 or 11x6 APC prop to have the engine work okey!
If on the other hand you have the shorter pipe made for the 6,5cc Q-500 MVVS engine and high rpm (No 3246 pipe) Then you better use a 9x6,5-9x7 or 9x8 APC prop, but remember that this pipe is made to give high speed to small Q-500 racers or Q-40 pylonracer and is not sutible for ordinare "sport R/C airplanes.
You could see some of these engines and planes at my homepage http://hem.passagen.se/airracing
