Its sounds like your your front tires are touching part of the front suspension and are locking up. Set your car on a car stand, free spin the front tires, and turn the front tires left and right with your controller. Are the tires rubbing on the suspension causing them to lock up? If they are, something is assembled incorrectly (I would check and make sure the black plastic spacer is correctly behind the castor blocks - a common mistake that would cause that, the second is that the left and right castor blocks are on the wrong sides).

I was wondering what motor you guys are using for mod buggy? I have been out of the whole electric game for the last five years or so since brushless and lipo packs have really came into the scene. Any help would be appreciated. Oh and I am using the new lrp flow esc.

I'm running a Reedy Sonic 7.5 with an LRP Esc with the updated board

'im run 8.5 or 10.5 depending on the layout and amount of traction there is on the track.

looking to use an 8.5 Speed Passion here since its full mod.

Depends on the size of the track really. I was running a boosted 8.5 previously, but recently went with a boosted 9.5. The Orion motor didn't have the torque that I was looking for. I'm much happier with the Gen 2 Tekin that replaced it.

That said, A blinky 13.5 would get the job done most of the places that I run.

If the motors had the torque, I'd say on the track I plan to run on a 13.5 or even 17.5 would be plenty, just need the torque. But some of the guys run even 4 pole SCT 4x4 motors.

Most of the tracks in the Midwest are indoor high bite clay. So that is what I will be running most of the time. When I was racing a lot before my wife and kids came along I almost always ran reedy 12 turn double geared 81 21 if I remember right. So basically I just want something comparable to that. Thanks again for the help.

7.5 - 8.5 will fit the bill then.

Most people I know that run mod use a 8.5. You can always turn power down on esc if it is to much.

yup pretty much.

I just ordered 7.5 and 8.5 for SC and buggy respectively. If I need more than that, I may as well just give up LOL

I run a 10.5 tekin motor. Not the fastest by any means but there is nothing I cannot clear. It's real tame and controllable. I had a 6.5 but that was too much.

I think I read it it like 16 grams total added

I had my orion 7.5 in and it had very little punch. I threw my 10.5 back in and got more low end and more control. Suddenly I was pulling very fast laps, I just need to get to the track on a more consistant basis...but dont we all

I was using green slicks and boy I couldnt stop the wheelies. I am going to try and loosen up my car...

Just wondering,you guys running the shorty packs in 17.5 class. Do you leave the weights in the rear? I run full packs now and I have ballast weight and 1/4 oz each rear triangle. I have tried removing the weights and the car just loses alot of traction. So I guess what I'm trying to say is the whole point of running the shorty is to reduce weight and improve handling right? So to me it wouldn't make sense to run the shorty without weights. As far as handling with the shorties,I don't think I can get my buggy to handle any better than it is now its awesome. Guess I should maybe try and borrow one and try for myself.
