Pinions

[jamiesawyer28041978]

Hi guys I have just checked my 450 and its the 11 tooth pinion on it . Midlands are selling 15 tooth pinions and I was wondering what this would do to the head speed. Im going to fit the 12 tooth to see how it improves things cos I thought the helli was a bit twitchy due to the head speed being to low. Any in put would be nice guys .

and the other thing is it 's a Align 430l brushless outrunner . Is there a better motor more powerful on the market.

15 tooth will be way too much I think.
13 is probably your best bet.

Re motors. The new 430xl is a great motor at a good price.
Take a look at Ashley's site for more test results.

Ive seen a motor which is the same as the one that came with the trex 3550kv 430l motor and it is 4050kv 430l motor . I presume this will add more power but flyte times will be reduced.

I have 3050 rpm head speed with the 13T pinion.

Thats plenty fast enough IMO..
