Savage Nitro to Brushless Conversion - RC-Monster Forums

Well, I finally did it and made the decision to convert the beast. I was having trouble tuning it and realized the motor was toast. The clutch bell bearings also blew out, so frustration helped the decision along.

I am holding on to the motor and plan on rebuilding it for fun, and might convert back one day. I am doing this mod to be able to do just that. Using as many stock parts as possible. I am also too cheap to buy a new chassis.

Here are the parts I used:

Tekin RX8/T8 - 2250kv - 4038
Robinson Racing 48T spur
Kershaw Hardened 12T pinion
Kershaw Dual Motor Mount
Flux Idler gear - HPI100905
Titanium Drive Shaft - HPI86345
H/D Drive Gears - HPI102514
H/D Cup Joints - HPI26276
HPI Wheelie Bar - HPI85245
Flux Battery Boxes - HPI100908
Battery Mounting Kit - HPI100909

To start this modification off, the nitro stuff had to come off. And there was a lot of it.

I thought about keeping the mechanical brakes, but I am going for simple with the conversion. I saw how well the flux brakes work with the Castle setup, so I figured that's all I need.

i just saw this thread on rcu.

even with the CEN diffs and the big tires, you should get at least a 16t pinion for 4s and use the 12t for 6s.

Thanks, I am going to pick up the run of pinion sizes.

Here are a couple of videos of it's maiden run. I need to go up on the pinion a little and this is only 4s. 6s is coming.

I'll have better video when I get it out to a track or bashing place with jumps.

Damn, you are good. You are/were actually right. I discovered that this morning and tightened it up and added a drop of thread lock this time. I can't keep it from flipping over backwards now.

It has a 12t in it now which is too small even with the CEN diffs and Goliath tires. I have some larger pinions on the way. This thing has stupid power. More than the Flux's I know and have driven even with all the extra weight on this tank.
