Default FG, rear diff-epoxy?

Anyone ever fill there rear diff up with epoxy or such for any reason....ie broken gears, want lock up, structural support......etc. How do you like it and does the truck still turn corners? Yes I know you can buy alloy rear diffs.

Why dont you just buy or Build a live axle? im not sure about it turning good in most cases a posi rear end can be a tough on the steering & wipeing out alot. but it is a must for a drag set up. i would think a limited slip rear would be your best choice in your truck.. www.quarterscaleberetta.com

I Know that J.B. Weld will work that stuff is very strong. dont use the quick set stuff though it's not very strong. if you use it use the orgianal stuff. I am building my 1/4 scale car with that it will hold them gears together with no problems.

I just ran the truck tonight......omg, I wish I did this a long time ago. I run the truck in 95% dirt and never on pavement.

I know what you meen.. Right no i run and all alloy adjustable diff that allows me to completely lock the rear end if i wish to. it's a pretty nice upgrade. ofcoarse if you want your one wheel wonders back just loosen the allen screws a bit

look closly at the rear and you can see it, the casing has a hump in it for the allen screws sit, so you can make your adjustments


P.S Incase you want to purchase this down the road. the part number is 8485/05 But most sites i went to do not show a pic of it anymore []

I had a diff crushed, and running totally locked.

I also run mostly on dirt, and my Leo was totally undriveable, would only do dounuts on dirt, ran fine on tarmac. (mildly Ported 29cc engine and tuned pipe)

prolly has a lot to do with the pipe as to how fast the truck comes around on you, with a locked rear diff. I have a stock engine with a FG pipe which is known for smoother power rather than the snap that would likely spin the truck.

Well I was out tonight racing some HPI Baja 5s and I really suck under pressure. Well sure enough, powering out of a corner and my FG MT wants to sping 180 rather than get up and go down the straigh away. Also bashing around between races it took a good tumble, ripped out another frt upright and broke an out drive. So maybe a solid rear diff is not for everyone. But I was winning the start and straight away against 3 HPI Baja, 2 of them are 30.5 engines with padle tires in very loose dirt. Hopefully this helps others make a decision.

it will be down to tyres above anything else, you dont stand a chance against a buggy anyway tbh. stick to racing other monster vehicles. have you got the softs on the rear and hards/mediums on the front?
