That's insane. Did you ever make it through a whole pack without breaking something? How fast would it go?

Honestly no lol. I snapped 4 carbon fiber links in one outing. If I would have been smarter about it I would have built the truck much more stout with machined lower links and aluminum upper links. I'm not real sure how fast it would go. It moved out though. There's a video on YouTube of it. I think the name is 7700kv predator?

I'm gonna run 2 castle sv3 5700kv or 6900kv combo's. I'm undecided on what body I want to put on the clod. I picked up a roller without a body for $50 on offerup. Also just built a lunchbox and might put my castle 4600kv in it.

I seldom make it through a pack either, but it has gotten much better. Metal gears, aluminum axle tubes/knuckles, TTR front diff, and soft/long travel suspension have helped a ton. Most problems now are little things; thankfully, I haven't had to rebuild a diff for awhile.

Watched your video. Man, that thing hauls.

I down loaded the photobucket app and then just click the pic copy then paste.

Are you using the 1/8 or 1/10 scale proline monster truck body?

Great looking truck. What kind of shocks are those? We need some action videos though, so drop some batteries in and see what it can do. I'll warn you - brushless Predators are a handful!

And, who wants to guess how many runs he will have before a major :explosion: ? I say less than 3.

It's broke all 3 times ive had it out :(. I have stripped out two wheel hubs and broke an axle tube. Any ideas on keeping the hubs from stripping out?

Sorry you busted parts on your first three runs. I was hoping your experience would be better than mine. I think I've made a complete run about 3x without breakage since I built my truck.

I don't think the Tamiya wheel mount system is up to brushless power. I tried a few different solutions but eventually went with RC4WD "Extreme Duty XVD's" and Ofna Pirate wheels and tires. So, now I have hex drive and it has been very durable. Not a cheap fix, but at least it was a fix.

I'd also recommend aluminum axle tubes and knuckles. Some people on this forum can actually get some life out of the stock plastic ones. I never could and got tired of changing them. My tubes are Hot Racing and they've been fine - most recommend the Integy's though. I've had both the HR and Integy knuckles, and the Integy ones are beefier but still have steering stops on them.

Aluminum hubs http://m.ebay.com/itm/130855322986?_trk ... mwBanner=1
Also turn down the esc's initial brake and punch control. This will weaken initial launch and braking torque.

Those are great suggestions, and much cheaper than my idea. I found that the little nubs on the inside of the wheels would often break, so I bit the bullet and went with the hex drive. Everytime I fixed a weak link, I just found the next one.
