Well done there! They fly nicely don't they?

Your engine sounds quite lean, I would richen the high needle a few clicks

Heya,

Yeah towards the end of the tank the engine will not have enough fuel to burn and there for it increases its rev's and then dies. This can be quite dangerous if the engine is quite lean to start with. You can pop the piston by the added increase during the rev up - die of the engine.

Listening to that video again i would richen the main needle by half.

Regards
Callum

If you are going to go from 15% nitro to 30% nitro you'll need to add an extra shim to the head of your TT53 AND you will *need* to open up your needle at least 1/2 turn. Also open up the idle a 1/4 turn.

Tune it in from there.

Thanks guys got it running good this weekend I got a local guy I meet thru RR "aceisback" helped me out and met a good group of guys. I might need to redo my clutch liner as it engages a little later than I want, could the liner be re-used? Will get more videos when I can.450Pro~Vision50~EXI450~

I strongly recommend relining your clutch bell before you break the clutch. I'd get a Raptor-90 liner and just cut it to fit.
