I am just now getting back into airsoft and I need to pick a new motor from my project. I am going to be running 400fps, and I want a high rate of fire. Should I get a super torque up, or a high speed motor. I've always used super torque's but ronnie said that the high speed motor would hold up with 400fps. help.
IMHO, stick to Super Torque-up motors with 400fps springs. Unless you're prepared to rewire your gun with good quality, low resistance wires. I noticed too much amperage draw when I tried High Speed motor/400fps combo. Handle was getting warmer than normal & would blow 20A fuse on hot days. You may also want to consider using 10.8v battery or higher.
If it only takes a M120 to get your gun up to 400 fps the High Speed should be fine.
