Vid of LT-200A ESC in action in CRT.5

[snellemin]

I bought 4 A123 cells from Holmes Hobbies and homeboy ships quick. I was going to get me some G3 Lipos, but the A123's were just a good deal. Anyways, I built the pack really quick and ran 3 packs through the crt.5.

Brian calculator spits out 70mph. It looks more like 65mph. The motor just goes nuts on 11.7 volts and the poor crt doesn't know what hits him. I'll do a vid again once my new foams come in. Motor is around 130F.

Nice vid. That thing looks pretty darned fast to me. Nice setup to Snelleman. It kind of reminded me of the old days running slot cars on a track. That thing really rips.
