Good honest review. Surprising. I would have thought the KM would have ate them but the top just disintegrated. Tires will make all the difference. And glue.

Awesome video! When my boy is old enough maybe ill get him a wpl kit for Christmas- and ill have to hit you up for required upgrades!

Use some rolls of pennies for weights and use the amount of pennies as a penalty for a WPL Multi Truck Offroad shoot out. like a handicap sort of system, more weight would benefit them flexing in lo range ya? Sweet video thumbs up!!

That was AWESOME to be fair the first two completely destroyed the dirt at the top of the hill great video!

Tough run that David,if the dirt hadn't been so dry,you may well have managed to get them over that crest.

First... great vid and comparison I thought the kit was gonna make it till it had a blow out 👍💯💨

If the RTRs just had a bigger motor and metal hubs they'd be amazing tbh

Ten out of ten for devotion to duty! Thank you for recording the entire test again - I found every second of this video quite fascinating. The RTR really shone, the kit did very well too and it was interesting to see how the KM, optimised for rock crawling, actually got hung up briefly on its 2-speed gearbox housing and dug its weighted wheels into the soft ground.
I did feel a bit guilty lounging on my sofa in the shade while you braved the desert for our education and entertainment, but you did get a very solid and interesting set of results!
When I rushed out and bought an RTR B1 I was horrified at the high wheel speed and utter lack of torque. I hope that new buyers whose introduction to RC trail trucks is an RTR WPL B17  will have a far more positive and encouraging experience when they take their new truck out onto the trail   : )

Nice video. Looks like the kit wins :D
I would like to see your MN's on that crazy trail.

Great video thank you! I have my B14-KM on the way in the mail now :)

He's baaaaack!  I was looking forward to this test, or re-test I should say.  Looks like the weight of the KM may have hurt it a bit in the soft stuff.  I wonder if kit tires on the RTR would have done the trick?  THANK YOU for getting back out there and sharing with us!  How would the MN's cope in this situation 😉

Fantastic comparison video! That new RTR did way better than the first RTR ever could have. KIT seems to be the way to go on soft terrain such as that loose dirt, the KM was way too heavy for that and is mostly suited for pure rock crawling and packed dirt or gravel.

Just a thought but the plastic bushings from the stock axles might be good spacers for your leaf springs

1st one, mine was an original RTR with all the disadvantages... #316 gearbox and 130 motor, plastic axle gears, bang-bang steering. beast now with the C-frame and upgrades. they don't need much for wheel weight with the battery under the hood, even a wimpy little 800mah 2S.
wheel weights on the MN soft tires is 4 turns 2 mm solder up front, 2 turns rears. its just a little wheel weight to help it flex, and lower the CG just a little bit, not like I'd done my MN D-90.
2nd one did really well minus drive shaft popping loose and wheel falling off at the end.
3rd one those printed rims are offset really wide, tire trimming may have helped a little bit.

the "deep dish stock rim" mod, with tire beads further apart the center tread becomes softer so more pressure to the ground at the tires corner lugs, the center tread big dots get pressed up (tread face against the ground going concave), so the corner lugs turn down into the ground more. hard to put into words but when you do a set and clip up a set of tires, you'll feel it! when you drag your finger down+around the middle of the tire.. a little pressure down the center and the corner lugs are turning in+up trying to grab the sides of your finger, weird but pretty neat.

sidewalls are nearer vertical and tires stay on rims really well using wimpy old Elmer's rubber cement, is mostly just to keep tires from spinning on the rim. trim the 3 center dots around/down the center, and their corresponding (shorter) corner lugs 2 x 2 mm... there's a line in the face of the corner lugs as guide for some big toenail clippers. soft kit tires trimmed like that on the widened stock rims might surprise ya, but can't expect miracles in loose stuff like this hill peak in the video today. its hard dirt but sandy, always means 4WD shovel time when stuff like that is steep, and the little truck trying to dig itself right back to China!

previous video left ya a little more on (moron?!) the 280 motor transplant, my D-90 is SO heavy now it needs MORE POWER for anything steep. it may end up getting the reverse gear setup someday... output shafts turning opposite directions ditches a lot of torque roll, as soft as I go with suspension that's a big bonus.

so with a lot of debate if finally decided im buying the new white c24 kit its on its way right now im super excited😁😁

I think you gonna trim that tyre a little bit on the km and it's should be more grip to climb with a weight rig

You should do this with the c44 km

You should put the mn 90 tires on it. More groundclearsn like a 1/4 of in . I put the on my modend c24 3600kv 2s does 21 mph and still 4wd.

Wpl should make more tyres pattern like the 1/10 scale rc hahaha
