another crt.5 brushless in progress

[MetalMan]

The 4s1p "brick in back" seems like it would be the most feasible. Honestly I wouldn't go with any less than 4s1p to achieve 15mins. Just make sure it's geared for no more than about 35mph, otherwise that 15mins. might be difficult to reach.

I too like the 4s brick.

I took it to the track today and was quite impressed though I couldn't drive it for more than a couple packs. One of the king pin screws that hold the front steering knuckles fell out and the steering got sloppy. I also need to replace some other lost screws and locktite em all before I take it back out there.

I ran 3s because I could secure it in the car well with a zip tie. I was suprised that it was able to take the jumps level as long as the throttle was steady. Easy to bring the front up or down to correct with the throttle too.

For the battery holder I think I'll fasten a vertical plate that allows me to strap different packs on there using velcro. I've seen some gorilla velcro straps that include screws and some mounting washers for sale on rc-monster.
