I’ve got a Krytac Alpha CRB. Yes I known vfcs are better and I shouldn’t have bought it but that isn’t gonna help now. I’m wanting to do some upgrades to the gearbox and motor. What is the highest rpms motor I could use? I have a 20k in it right now and was planning to put a 30k in it. Someone mentioned that I could use a 45k? I’m just wandering what’s the best I could put in it without stressing the gearbox too much. (It’s a stock gearbox) I’m also wanting to do some internal upgrades to the gearbox. Again I know it’s gonna be hard to get parts for and hard to work on because it’s Krytac but that isn’t gonna stop me from doing it. What are the best upgrades to do and what parts are they and what brand do you suggest? I’m also putting in a new mosfet, it has one but it’s the one that came with it. I am planning on getting a gate tunable mosfet(I think that’s a thing?) which mosfets would you suggest? I’ve heard there are ones I can connect to my phone to tune???? Those are problably really expensive though. Please keep in mind this is a budget build so for the gearbox, upgrades that are under $50. For the motor, something that is under $75 (I can probably get new). And for the mosfet, also something that is under $75. I might be replacing the HopUp so what would you suggest for that? Sorry for all the questions about upgrades and stuff. I just don’t want to get something that’ll mess up my gun.
