| R2 2 speed RC4wd tranny DIG
i hope these R2's are doing better so I can have one again. How are these trannies holding up to large scale with big motors ? or 2.2 with cobalt motor I had one that lasted 3 feet with a 55t on 8 cell nhmi and a 11lb super with heavy drag brake. Maybe I just got a bad one I would really like a 2 speed and the new 2 speed with DIG would gain me 2wd front 2wd rear , 4wd hi low and front and rear dig in my setup. List what you have: R2 2speed with DIG or Just a 2 Speed So I would like to hear some feedback of your rig, weight, ESC battery, motor ? Thank u Last edited by toy4crawlin; 07-15-2009 at 09:20 AM. |

I can tell you what happened to my R2 HD when I used a 500 Cobalt motor and a 3s LiPo. ( 10 lb scaler with TLT axles) It lasted about 5 minutes of full throttle running. The bearings were toast and the 32P gears were almost melted. The gearbox was so hot I couldn't touch it. Forget about running any serious through these gear boxes, they just aren't up to the task. A stock plastic AX-10 tranny will last a lot longer. My opinion is, the issue is with the gear pitch rc4wd uses in the trannies. You need at least a 48P gear, but a 64P gear would be ideal for big power. |

I was using a 18t pinion on the cobalt 500 to get some wheel speed. I have no idea how fast it was in M.P.H, but I had to run to keep up with it. I just purchased a rebuild kit to fix it. mod 1 is decent, mod.8 is equal to a 32P gear. | |
