hey Gustav, im glad you like it!

About the battery slots, i don't ever plan on using 'cells' anymore anyways. I know it may look like it was meant for NiMH, but they're not. In fact I'll be standing my cells (A123 M1's) upright close in the center, there is still room for 'ultra capacitors' if want to invest in them. $130 for a 20V system, not bad, and extreme power.

The servo mounts, I kinda like having a barrier between the servo and the ground, that's just me though, most ppl probably prefer on the upper plate though like you said.

The ESC mount, rubber mounts are not going to stop shocks to the electronics, they will merely damper higher frequency vibrations; nothing much really. If you really want to protect it from shocks, make a mount that is suspended with springs from either side, and the springs connect with rubber grommets. :027: I've actually though about doing that...

I was originally going to make the parts from 7075-T6, but i've read around the web about horror stories that it can just blow about with a bang without warning. That is of course with excessive fatigue, and, the 6061-T6 is better at copping with fatigue. 7075 would have a clean break, were as 6061 will bend more before it breaks. If i could afford it, i would use 2024-T3 aluminum, this stuff is is like steel, it's light, and has superior fatigue resistance.

Here is another pic of top view. If anyone wants to view a 3D file of the assembly, just let me know. I can email it to you.
