possible fix for clod stall!!

[david37370]

hello!
as i understood it from reading, clod stall happens in MOA rigs when one set of wheels (front wheels or rear wheels) are in less tractions with the ground, and need less force to rotate, and then the other motor under pressure doesn't move until you throttle more, and instead the free wheels/motor will move.

I have read also fixes for it that say i can balance it with different pinions, or 2 ESC's and batterys, and other things, but i thught about it a little and a brilliant thought came: maybe connect the axles with an universal shaft (like the driveshaft)?

after all that is the disadvantage of MOA's against shafty's! the shaft driven cars rotate all the wheels at the same time, because of the shaft. that is very good cause then the power will ALWAYS go to the most pressured axle, and wheel. but what with the torque twist..?

the shaft im talking about will connect both the axles to each other, and have the power on the most pressured wheel, also it will will lower the COG because of the low motor on axle, and no cons! so far... hehe

what do you think guys? after all im 15 yrs old maybe i oversaw something...

by the way im waiting for the rs10 to come.. 2 days now..

The fix for clod stall is more power, period.

The setup you are suggesting already exist, we call those shafties. no MOA, center motor, center trans, two shafts out to a set of shaft drive axles. SCX10, Venom Crepper, Wraith, Ridge Crest, Losi....anything....(does Losi even have a MOA???) are all shafty production rigs.

MOA rigs are better suited, but limited too, Comping. You have Comp shafties too, but most are MOA. The idea behind MOA is to get teh drive shafts out of the way, no center mass, more clearance. Don't over think the RS10, this is a introductory rig. While there are Comp RS10's, they are expensive to build. We have no aftermarket support other then a few items that Crawford supplies us, hell the Venom Creepers has more support then we do. what we do have and factory replacement parts, they and cheap and plentiful and by the time you have replaced a few you have a damn good idea of what kind of rig you want next.

Get your RS10, swap the servos and drive pins out. check all the fasteners, cut the foams, adjust the suspension, throw in a 2s Lipo with a low voltage alarm and go have fun.

Hi, firstly I'll say straight up making it shaft driven will defeat the point of moa. You may as well buy a shaft driven car. IMO clod stall can be fixed but some injinuity is needed. Firstly the 540 swap will help a lot so I've heard someone can help me on that. Than gearing up the front one higher pinion than the rear. And run 3s lipo then that should help heaps. Plus there's no way of making it a shafty anyways.

Pinion and heck 2S lipo on the stock 380's was enough for me. keep her lite too.

3s lipo got rid of 90% of my stall

8t pinions, duel esc's, banebot 390's and a 3s Lillie the way I have gone and wow what a difference.

guys you dont undrestand! you think that i meant just making it shafty?
so no. i meant leaving it MOA, and connecting one motor to the other motor with an universal shaft, so both motors rotate in the same speed always! the motors are still on the axles

we understand what you are saying, but that would be pointless as you would be defeating one of the primary ideas behind MOA which is to get rid of the center drive shafts. besides, what gear box are you going to use? not saying your idea is bad, it's just not a valid solution for the problem. The solutions to clod stall are all stated above. if you want the axles to spin together, then you need to a buy a shafty, simple as that. To do what you want to do, you will have entirely too much time and money invested in a rig that is unusable because nothing will work right together in the end and then you will realize that you still need to be able to Dig.

With a shafty, we have either dig front/rear or no dig.

With MOA and dual ESC, we have the ability to proportional Dig, meaning that rather then one axle being locked and the other pull, we can limit the movement of one axle and pull with the other.

Sorry to burst your bubble, man, but Doc is right. You're over thinking the problem. For what you would spend to add these drive shafts, you could easily just buy a shafty to begin with. The functionality of the rig would suffer and the mod would essentially be pointless with the small motors the RS10 comes with. If they have trouble with keeping one set of wheels turning under load, what makes you think they'll keep a drive shaft and another set of wheels turning?

 

[david37370]

ok i understand, you're right. so the perfect solution is dig that can limit but not totally turn off one set of the wheels. where can i get one? considering i dont have any tx/rx except the one im getting with the car...

 

[Docwolf]

you will need a second ESC and controller set that will allow proportional mixing like a hacked GT3b (or c). BUT, lets slow this train down, you are just getting into the hobby. As i said before, spend some time with your rig in it;s mostly stock form. there are minor upgrades, as I laid out above, that need to be made to make it usable. out side of that, i wouldn't start planning anything until you have a good idea of what you want. no two people crawl the same way and no two rigs are modded the same way, that is the art of this hobby. just get your rig and go play, in a month or so you will know what area of the hobby you want to be in....hopefully. heck i still don't know. I started off a scaler, now I am building a hill climber and some what comp ready MOA tuber.

 

[david37370]

thanks you've given me some motivation! im getting my rig in 2 days
still... i've got an old rc toy, maybe i'll use that radio to cut off the rear wheels sometimes XDDD
