||This gear is pretty good.
Ive installed this gearset in 2 builds and it shoots fantastically. They will get you shooting 30+ rounds per second on a fully charged 7.4v lipo/9.6v nimh.
This is a 16.32 ratio gear so be sure to have similar ratio bevel and spur gears.
It is NECESSARY for you to have steel bushings due to the stress these gears handle.
DO NOT use a HIGH SPEED motor with these, as they are not a stable platform and might not be able to pull the gears. ONLY USE HIGH TORQUE MOTORS.
DONT FORGET!, in order to install these and get proper feeding, you MUST modify your TAPPET PLATE by measuring the engagement arm 11mm and cutting the excess away.
Also, be sure to do an angle of engagement mod on your piston in order to have proper engagement and piston life.
These can handle an m130 which will only get you about 280 fps with these gears because they are essentially short stroking your system to 8 teeth instead of 16 so you only get about 60% of your spring's power. I recommend getting a spring guide spacer and an m120 for the best performance.
DO NOT use these in a gun with an inner barrel over 363mm because they will lower your fps and range.
if you need anymore tips on installing these. Message the nice techs at Evike :) or email me at firstname.lastname@example.org
