Default motor KV question

I'm an experienced racer looking to build a basher truck, and I've never used 1/8 scale gear before. I am looking to use 4s battery power, a Hobbywing XR8 Plus ESC, and the Hobbywing 2250KV 4274 motor. Is this a correct combination for this vehicle or will I be chasing gearing? I've seen KV's on this thread listed up to 4000 and I don't want to be chasing gearing to start out with.

Basically, I'm not looking to set a world speed record, but I know what a mod touring car and mod 1/12 feels like, I want that kind of rip out of this truck. Wheelies on demand.

That 2250 will wheelie on demand with 4S. It's a whole different feeling than mod touring or 1/12.

I just got mine in the mail and soldered in my 4S power system, and the combo of this truck and that Hobbywing 4s is a good match. I had to put a nice big glob of 2.5 million weight silicone in the center diff otherwise it was just roasting the front tires while the backs were barely moving, and I'm probably going to go with some thicker shock oil, but its been a lot of fun so far. If the steering bellcranks were metal instead of plastic, it would be 10/10.

I guess that the question for this truck is simple: Is it better than an E-Revo 2.0? I think it is. The E-Revo isn't junk, but this Pro MT 4x4 seems to be more like a somewhat built-to-a-price 1/10 truggy than an overgrown tmaxx. The chassis is metal, the driveline is steel, and the engineering seems great for what is explicitly a basher truck. If you're looking for a fun vehicle, this thing fits the bill.

Nice Chevy truck body AJ Dragon!

This truck is a lot smaller than a Revo 2.0. An Arrma Kraton would be a better comparison to the Revo. A lot of people compare the Tekno MT410 to the ProMT 4x4 but it's a lot bigger too. This truck is comparable to the Stampede 4x4 and the Redcat M10E.

Hi
I made a new part for my truck, a chassis brace. I made it out of a piece of hardwood flooring. I still have some more tweaking to do to the shape to make it look better and add a finish to it, and get longer screws in the front, but basically it is done. The shock tower will have to be beefed up a little bit on the back side to prevent the screws from being pulled threw the plastic if I land wrong or crash hard. Now if I only had a CNC machine to make aluminum versions .

It looks like some good woodworking, but I am not convinced we need a chassis brace. If you wanted something for it I think that two long turnbuckles from the front bulkhead to the rear would be enough.

Hi

Actually it's a know problem with this truck that on hard landings the rear end will bend upwards and then bend the drive shaft and possibly brake the rear diff case in half. This truck should have come with a three point chassis brace instead of the short two point brace. If they had run a brace from the rear diff case to the chassis and then to the center diff case like I did, then there would be no need for people to make there own. Running a brace from shock tower to shock tower on "THIS" truck is not a good idea because of how soft the plastic shock towers are. One hard landing and you will shear the towers clean off. My brace is actually pushing against the top of the stock chassis base, the diff case and the shock tower, plus I filled in the cavities on the back side of the shock tower with super glue and baking soda to strengthen the shock towers.

I ended up selling my Pro MT 4x4. Was really tired of all the things going wrong. First it was the servo saver issue, then came the pillow ball issue. Once those 2 where taken care of. Next came the weak hinge pin blocks and the rear diff cup c clip popping out. I was so tired of this thing. I ended up selling it, i took a big lose but am happy to be done with this thing. Ill stick to my Teknos and Arrmas for now.

Hi

By any chance does anyone know what the shock spring strength ratings are? I have found more springs that will fit, I just want to make sure that they will be stronger then the stock springs.
