Rebuild REX R1/R2 Grips Cracking
Digging way back here. I'm rebuilding 3 rex R1/R2s that I got for free. I have replaced all the orings and batteries and the leaks stopped. have not had a chance to fire paint, but they fire fine dry. The only issue is, i found some rebuild kits that came with new grips. I was pretty excited, but after installing one set of grips the new ones cracked in the same place as the ones i took off. is there a trick to keep these from cracking or are the old plastic just too brittle.
