I've had pretty good luck with
my Hyper8. The only thing I've broken is a shock tower, but that was from a direct hit on the tower with a wall at around 50mph. I've also had the CVD set screw loosen, so make sure to lock-tite those well.
You'll need the following for a Hyper-based buggy, but this setup will be similar no matter what you get:
-
Motor mount.
- Motor. Take your pick. Feigao XL motor for the cheap end, Neu on the high end. The kv depends on the voltage you use. Shoot for around 35,000 rpm max.
-
Battery tray. I know Mike can make custom sizes depending on the battery you choose.
- Battery. I'd go with lipos for weight/runtime/power. 4s is a solid start. 5s and up would be better for higher voltage setups, but then you may have issues trying to get them to fit under the body. For runtimes around 20-30 minutes, look for 5Ah capacity. For higher runtimes, you'll need around 8Ah. Of course, this depends on how you drive, ESC settings, terrain, gearing, etc.
- ESC. Up to 4s, the
Mamba Max is a good solid ESC. For 5s and 6s, I'd use the
Monster Max. Both have tons of features, computer programmable, built-in LVC, great customer support, etc. If using the Mamba Max, you should use an external UBEC - the Monster Max has a switching BEC built-in.
- Depending on the height of the battery you use, you may have to raise the body a bit for clearance. The sides of the body are kinda shallow.
- Mod1 5mm bore pinion. Tooth count determined by the speed you want.
- Spur. You can use the stock steel spur, but they are heavier and noisier. The
Kyosho 46T spur is a direct replacement. Quieter and lighter, yet still holds up fine.
