| Is a Tekin Pro4 a bad idea?
So, I'm in between builds and I have a spare MMP laying around along with a Pro4 3300Kv. Note: This is not an HD, not that that makes a huge difference.... I was browsing around the interwebs and forum to try and figure out what I might want to put them in, and I came up with a Twin Hammers kit. Now, I'm not new to high power systems and how they like to eat parts, it is just that I'm not super familiar with the Twin Hammers and its durability. Basically, would the drivetrain explode the first time I pulled power? This would be be running 3S 2200's, but I'm not opposed to stepping down to a 2S pack if that would make the motor substantially more survivable. Also, I usually set my slipper on the safe side, so there will be some give to the transmission, but I just don't want to be replacing gears every other run... |

I think the RTR comes with plastic gears in the transmission, so that's probably a no-go. Kit comes with metal, and should be able to handle some abuse. Kit is 2 speed though, not sure if you're looking for that.

I have found the TH very durable. The durability issues I have come across with high power have been 1) the driveshaft set screws fail. 2) a bent steering link. |

I run a 4100 kv brushless on 3s in my RTR and have had no driveline issues. Having said that, I run strictly in the dirt where traction is limited. No wheelies in the street and you should be fine.

People buy Rock Racers to drive on the street?

As long as you run the metal trans gears, and don't lock the front diff, I bet you'll be fine. If the diff is locked you can expect to break cvd's during violent one-tire-hits-first collisions/awkward landings. Not that the plastic trans gears are bombproof, but my brothers been running them with a Castle 5700 for almost a year with a very heavy throttle finger without issue. |

Mine was fine until I locked the front end. It's grenades front CVd's now extremely quickly. Just for that reason I went back to brushed to try to keep it reliable. Before the locker I only hurt a sour gear (it was my fault) and the. I switched up to 32p gears. all depends on your use. Without a locker it's useless for rocks.

| Re: Is a Tekin Pro4 a bad idea? I didn't even think of that. Does it still act like a locked front end in the rocks until bound? All I do with mine is trail and rocks. Mostly rocks. So I just stepped down to a brushed setup to help longevity of parts. I may have to look into the putty.

| Re: Is a Tekin Pro4 a bad idea? I used Mack's Pillow Soft Silicone Putty Earplugs in my front diff. Allows for a little slippage but crawls the rocks well.

| Re: Is a Tekin Pro4 a bad idea? Awesome! If the step down to the brushed system instead of the big brushless doesn't solve my problem, I will have to try this. When you applied the putty, do you just install it in the area where the spider gears and cross pins are or in the whole differential? Then bolt it all back together? And is there a specific amount or fill it until you can't put anymore in it?
