Cylinder porting?

Hello, just a quick question I know within the gearbox sometimes the piston cylinder is ported due to there being a shorter barrel. Since the umpy uses such a short barrel is it a good idea to use a ported cylinder, or just stick to the full length one?

Thanks for the help in advance.

Mine has a full port cylinder and standard barrel length and it shoots well sitting at about 280fps.

That is exactly what I am looking for in fps, could I please ask what modifications are done to yours from stock?

Im putting one of these on


If you look at the inner dimensions thats huge, then inside gonna fit a

Or a 11v equivalent.

dont reckon u will need it. the 11.1v 3s battery lasts for ages
2s might be a bit slow

So there are no problems running them at 11v?

Spose it depends on what motor you using.

Thats the golden question I have no idea…
