Ok, so a few of us have one of these:
Review:
This thread will be about what and what not to buy for these, mods, and repair help for new guys.
Which to buy
If you already have a radio system with cheap receivers like a FlySky, go and get one of the Brushless BND models. This will give you the best value. If your receiver costs more than $30, you may as well get an RTR and save yourself the trouble. The brushless RTRs come with a lipo and slow lipo charger, and the brushed models get an nimh. The BNDs do not come with a battery, but something like the Gens Ace 1550 is a perfect fit, save for cutting a notch in the battery tray to let the wires out.
Tires and Wheels (list will be edited as more members contribute)
I have tried both the Iron Track buggy/sc treads and the MT tires. It's a bit conflicting. Primarily running on the street, the buggy pins wore quickly and got less than optimal traction with the ballistic BL system some of these come with, and burnt off quickly. The MT tires have provided the best versatility for me, but they are rounding out the D-shaped hole in the wheels. This is a problem.
Durability mods
TheJANG abused his quite a lot, as shown in the review. These are tough little buggers, with one exception: The dogbones. These are plastic with only little bits of metal on the ends, and these like to snap. This did not happen for me with buggy tires, but I suspect that was because of their lack of grip. If you take a tumble with the throttle on, you have a high probability of breaking them. The aluminum upgrades are a must. Also, as mentioned in the tire section, the D-shape in the wheels is not the strongest. Set your wheel nuts so they are not too tight (wheel should spin freely), but not too loose, and lock in place with blue loc-tite.
Will add more later.
