I'm really enjoying mine now. There are a few upgrades and stuff I did to get it to be pretty durable though. Here's some things I think is a priority for upgrades.
1. Shocks. Tops pop off. I got traxxas 5862
2. Rear ball stub strips out. I got HR aluminum hubs and rpm 4-40 rod ends. Or you could do the hollow ends with a nut and bolt
3. I adjusted my slipper and lowered the punch setting to 1. I like it much better and my drive train has held up.
4. Input gear metal. I stripped where the pin goes in. Replaced with metal one but also I think my slipper wasn't adjusted correctly along with the punch setting was high.
5. Nylon locknuts for the wheels. I tightened the front too tight and messed up the bearings.
6. Tbone front bumper. My son broke the front arm the first day. Not Arrma's fault, ran straight into the leg of a metal bench. The bumper is awesome. I ordered a rear one too yesterday.
7. Dogbones. Just make sure they come with the 83mm (pin to pin) mine came with the 80's for some reason. Been fine since I got the 83's
My electronics have held up fine. I bought a set of Vorteks wheels and tires and love it. The offset is wider and I think I paid like $18 front and rear from amazon. I did order some 1/8 buggy tires and the 12 to 17mm adaptors.
I really enjoy it now with the upgrades. You will spend a little more on upgrades but for arrma to sell at that price point somethings gotta give.
