Dispas Posted September 30, 2012 Share Posted September 30, 2012 Heyas I'm trying to do some upgrade work with my friend on my TM P90 tri-rail. I want to put in metal gears, new spring and a few other changes to up the FPS which over the years has slipped down to about 230fps, of course I don't want to break the bank doing it. My friend is the technical expert but to him, price is no object... to me it very much is! My friend has suggested kit from america which turns out to be three G&P Branded gears; Sector Gear, Spur Gear, Bevel Gear at a cost of more than £50! For three gears! I'm going to be cautious of putting in too many links to avoid the spamfilter, but these are some much cheaper HK choices I was hoping people here could help me evaluate. If possible I would like to buy from this site as I've had good experiances with them before and they ARE wholesaler cheap and I have other stuff I want to order from them: http://www.khmountain.com/airsoft/product_...roducts_id=3489 http://www.khmountain.com/airsoft/product_...roducts_id=1773 http://www.khmountain.com/airsoft/product_...roducts_id=2455 My principal choice manufacturers seem to be; Element Jong-King Dream Army (Classic army?) Or should I just stick with the G&P and insist on finding a cheaper place? Also would like to know if there is a big advantage with my Ver 6 of changing to bearings from brushings and if/what ratio gears my gearbox needs? I'm given to understand I want standard speed/torque parts. Hope I'm not asking too much~ Link to comment Share on other sites More sharing options...
