what gears to buy

[jackp1]

im waiting for my hurricane 550 carbon fibre, gaui 1100 kv motor,& gaui 75amp speed controller & 3300mah fp 3s1p batt's 20-30c,500mm carbon blades,and i want to upgrade the gears to the revco one's and since the heli hasn't arrived yet, i dont no what set's to order, and i live in the uk so my order has to be made in the us. and id like to order the gears so they turn up about the same time so could some one tell me which one's i need so i can order a couple of sets i want to change all of them if possible and i guess id need a pinion as well now im looking to set the hs to about 2200rpm so with the new gears what pinion do i need to acheive my 2200rpm thanks

there is a head speed calculator at readyheli.com - bit I am guessing a 24 tooth pinion with both Revco gears.

email John at readyheli (sales@readyheli.com)... and he will know exactly what you need.

he is the original Revco distributor for the gears.

2200 HS is pretty high... and those batteries are going to be gone in less than 5 minutes (about 4 to 4.5).

thanks for that, i want a pritty high hs as i like the extra power, & the batt's that's all im aiming for is 4-5 min flight time i might be ok with 2100 hs il not no til i get the bird up thanks
