Can someone advise me as to the recommended gearing for a 4500KV brushless GTP car ?

What Size Motor ?? ... Brand ... and what type of chassis ??

Checking with Kim, (who has been running 4500kv cars at Seagulls), they have tried and run both 13:32 and 14:34.
Both apparently work well

Obviously your results may vary, depending on chassis and body choices but that should put you into a workable 'Ball Park' as it were

Thanks Stoo i am getting so much conflicting advice . Some say 11 tooth pinion, some say 13 and some say 14.
I think i will give 14:39 a go see what happens .

That will probably work fine
Kim's tests, were with the KC motors btw

Try to keep the 'Mesh' relatively Open and Free ie: Not too tight
If you experience any 'Cogging' or it not wanting to restart, perhaps try a smaller pinion.
