Question about upgrading km4 RISkm4 ris lipo spring
Posted 03 December 2013 - 07:11 PM
I'm having trouble finding a solid answer on this. I want to upgrade my km4 RIS. I'm thinking a 11.1v lipo and a stronger spring. I'm currently chronoing with .2s at ~370 fps. I'd like to get it close to 400 without going over. I'd also like to increase my RoF, hence the lipo. I read that to stay in spec I should get no larger than 15C.
My Question is is it safe to get a 11.1v 15C lipo and a stronger spring?

The KM-Head 6.02mm inner barrel I just installed in my RM4 took the muzzle velocity with 0.20g BBs from about 378fps to 400fps and didn't require cracking the gearbox. 10 minute job.
