Motor trouble

[TurboChargedHonda]

I have tryed a many of motors ranging from the 170 to a 540 but it come with a 170 I think. All is the same oh and yes no reduction. Go big or go home right. I have speed controle on the remote so I can super crawl or turn it up and burn the tires off it. Well it is supposed to.

A 170 sized motor is significantly smaller than what you currently have now. When the whole car was stock, how was it configured (gear reduction wise)? Did it have a transmission? I think your problem is torque-related. Both the drivetrain and the motor do not have any manufactured issues, but the motor simply does not have enough torque to handle the load of the car. More gear reduction helps increase torque, and switching to a lower turn 550 sized motor would also help.

He has (or had) a 540 80T motor on it at one point. Without being able to see it and not knowing anything about the kit I'm stumped.

It doesn't look like there's a lot of gear reduction... What turn motor did it come with stock, and is the current motor overheating if you try to drive it for a while? If you still have the original motor that worked, try putting it back in and see if it has the same problem. If it doesn't it is something with the new motor.

I have tryed a many if motors but it come with a 170 I think.

I have tryed the 13t a 80t and a couple in-between the 380 and the 540 not to shure the exact size and all the same. Sometimes it won't even move.

I have installed a set of soft rubber tires and to make shure it gets traction a bunch of weight. I was thinking that last night I just can't believe that a 540 is not big enough. The 170 had a transmission attached then the 380 had a gear reduction but I honestly didn't think a motor the size of a 540 wouldn't work. I'm going to weigh it and figure out a power to weight ratio to determine what size I should go with. I really should if done that first but tryed cutting corners and that we all know sometimes works out then other times causes alot more work in the end. If needed what is a few sizes more then the 550. I would like to go a bit larger to make shure I don't work one to much causing heat issues since I decided not to run a reduction gear set. Thank you for confirming my thoughts I am shure that is the issue now and as soon as I can I will try it out. I'll post what happens.

when the truck is not moving, is the motor spinning and the truck itself just not moving? or is the motor not spinning either? i would assume a 540sized motor would be fine, but it being direct drive (no reduction of a spur and pinion gear), am unsure if it might be geared to high.

You mentioned before sometimes it moves and sometimes it doesn't move at all. Does it move with the bigger motors on it but not the smaller ones?

When it doesn't move at all is the motor shaft spinning but the 2 drive shafts are not?

I don't think traction is a problem here. Adding heavier wheels and tires will only make this issue worse...
Just curious, but are there any reasons why you don't want to run a transmission?

I think that it is the fact that it is direct drive and the motor can't handle it and my not have enough torque correct me if I am wrong

Well he tried a 540 sized 80T motor. If that doesn't have enough torque to move this small kit then I dont know what would.

I wonted to have less things to fail in the future. Straight to the point and I just thought that the transfer case would of enough. I sounded good at the time. Haha well I have friends who just eat transmissions up with the power of a motor so eliminate that and no problems. It works great now I went with a motor I'm not shure the size but guessing around two times larger then the 540. It come out a large drill. Now it wonts to climb walls and flatten everything in it's path. I guess I just had to see if I could.

I agree with that or did. It is only a 1/16 scale rc but the 540 80t does not have enough to move it. Well I got it moving and was doing good but with a old motor and I think some how it got metal shavings invite from a somewhere not from it. It's cool I have a duel motor mount and I plan to have one 540 working the front axle and a twin 540 operating the back axle. If that don't do it I'll use the truck as a boat anchor. I have 3 other rc builds going on so one is bound to work. Haha I'll keep the weight down. Thank you all for sharing ideas with me and helping as much as you have. Now you probably know more about this truck then your own. You all have been a big help and it was fun so I'm not giving up and will post photos of it and others. You guys keep in touch the other builds are a old friends rc cars and we'll bringing them back to life I might have a few more questions for ya. I'm no rocket scientist.

 

[Daniel C]

I have to share this with you guys a friend thought it would be funny to give me this. The smallest rc car with full working shocks. Oh and below it is that duel motor mount. I'm still digging to find the motors for it. The motor unit is the 80t but I installed it to show. The other motor will be in the back side pointing the other way. What do you think? Will it go this time?

 

[Greywolf74]

Only one way to find out
