which rb engine is it????

all i want to know is how much difference a pro kit would make to my hyper 7; as in if i put the same engine, radio gear and servos and pipe in a hyper 7 tq sport and the same in something like a losi 8ight, how much difference would i get in performance?

lhs, i got my mine from modelsport and they ieally made gettin into nitro easy.. For the extra money ul probably get invaluable help too....

whats the difference between an engine that uses a turbo plug, n one that uses a standard plug? Noticed it when looking at the go 3 port engine...

are they available in the uk? Where can you get them frm?

just going to say, with a budget of

i noticed theres a go 3port TURBO engine for the same price as the 5 and 7 port... How good is that engine? Torquey? And what advantage does a turbo plug give you?

hehe, on paper the 3 engines rev really high, 40000+ so they wont lack top end....

but it uses a lot more fuel..... There are many powerful .21s out there, the axe rossi mamba (seen one in action - scary n quick) or cobra, or the go 7 port. The go engine is supposed to be amazing, and relatively cheap,

make sure ur engine has reachd running temperature, that usually means to drive it for a few minutes (i used half a tank before trying to tune) then you can lean it out... I got the same thing while running in my engine. but i just kept leaning it out and on the first turns i couldnt see much improvement but then it got A LOT better, now the engines an absolute screamer! Have you only tried leaning out the HSN just one 1/8 of a turn? And this is after youve done the running in process right? I couldnt really get a smooth acceleration when i ran my engine in because it was so rich.

what did you mean by everything? Did you make sure youre glow plug was fine or that your glowstarter was charged? U probably did but just checking hehe

why should the piston be left at the bottom of the stroke?

okay,.. How do i make i sure the piston is at the bottom of the stroke?/ how do i make be at the bottom?

anyone?

you turn the needle anticlockwise to richen it and best thing is to get a temp. Gauge so you know when ur too lean... Can save a lot of
