Cons:
- Bearings have melted on the front hubs, seems like the plastic wheel hexes touch the bearing shield, generating lots of heat and destroying bearings. I've ordered some boca bearings and metal hexes to help.
- Car lacks positive caster and adjustability. There are shims under the pivot blocks toward the back of the front differential but removing them isn't enough. I ended up grinding and trimming the pivot blocks for max caster which has helped but I wish there was more adjustment.
- Body posts up front are cut from the factory so you can't raise the body any higher without buying new ones.
- Steering rack horns should be slightly raised off the chassis for better clearing of rocks.
- Replacement parts are very difficult to acquire, aftermarket/upgrade option parts are virtually non existent.
That last part is the real killer, if I had known it would be this impossible to upgrade and even replace a broken part I probably wouldn't have purchased the car. Be that as it may, it's a problem with the company rather than the car itself but it certainly detracts from the overall experience.
Update: GPS measured a top speed of 58.0mph with a 3s lipo.
Update 2: GPS measured 73.4mph with 38T pinion 64T spur and 3s lipo.
Overall great job by HPI on this one!
