unfortunately with these rtr models it could be a defective board or transmitter (make sure your using new batteries in the transmitter and the trucks battery is charged). I would contact seller if its new or just upgrade electronics if you want the truck to perform better.

I recommend just upgrading it and you will have a better running truck. Go to WPL-RC.com and look for the V3 esc sound kit with controller and esc/receiver combo and bumps up the performance of the MN D90.
Hi David, Great videos, very clear presentation. I am new to the RC hobby and have just ordered a MN99S from Bangood. What mods do you think i will need for mild rock crawling. I am thinking about a 2 speed box, but I don't know if i will need other upgrades to get this to work ie head unit, receiver ect and if so what would you recommend for budget/hobby grade? Joel in the uk.
you would need to upgrade the electronics to use thebl 2 speed remotely. Also I am not sure the stock mn model electronics can handle the bigger motor on the 2 speed. The lights as well will need to be modded or replaced of you still want the light functions. If you want to run it stock it isn't that bad. just get some metal cvd style driveshafts for it and it should be ok for a while.
@@RunThatRC You may of done it already, but a total newbies video would be good. It hard to get up to speed with the tech language. Very basic talk about which components do what...
Fayee 6 spoke rims+tires are barely shorter and 7/16" wider track. wrap the front pair one if not 2 layers 2 mm solder wire (8 or 16 turns between the tire beads.. I went 2 layers). this lowers the CG, gives wider footing, keeps front down maintaining pulling and steering when climbing steep. the stock tires are a round profile, the Fayee are a square profile AND greater final width, does wonders.
I just use wheel weights. also adding metal axles and a metal upgrade kit for the gears and driveshafts will add weight down low to help with rollover.
@Run That RC David yup, mine has evolved like that, metal gears, axle casings, and drive shafts, A285004 oil shocks, on top of the wider+weighted (front weight only) Fayee 6 spoke rims+tires. bone stock the original kit would side tip or back flip when climbing, pretty easily, now its got "magna-traction" compared to stock.
I don't think i would run a 1060 in these rigs. it will be a tight fit and probably requires some panel trimming. also a bit overkill in one of these. I have a B36 kit with a XL5 esc and that had to be opened up to fit under the hood compartment. I have seen it done by someone. Smaller 30a ESCs would be a better fit. or the WPL V3 controller with esc receiver sound kit combo.
You can also buy clear sheet styrene (polystyrene) plastic from many hobby stores. Evergreen makes some, Plastruct too and in other types of plastic; clear acrylic (plexiglass), ABS maybe. Lots of options.

yup, axles and mounts, all about 6 mm wider. if you want to adapt MN axles to a WPL you'll need those MN bridge mounts to go with them, and add 2 mm spacers with longer screws to the shock tops. minor headaches if you want to monster out a C-14, but doable! for 1/8" more axle width its much easier to use JJRC axles and lock the diffs, then use Fayee 6 spoke rims+tires comes out near 3/4" wider than stock WPL
@@ginsonvillanueva8244 I use this product called Plastidip. It's a rubber coating for multipurpose use.

I am assuming they are 3s capable. I ran my B36KM on 3s with no issues. I'm using the WPL V3 esc receiver combo that is 3s capable so I assume WPL took that into consideration.
