coolhand country, I have indeed thought about lipo.. I own two AF 109d chargers w/ a psu, and have three 2s1p polyquest packs, but have never used them. I'm planning on trying the 16 sub-c's, and if it's too much weight, or not enough voltage, I'll look further into lipo/liion/ect.

tcolesen, thanks for the info.. still not sure on what batts would be best.. but I first have to figure out what vehicle to run, and get it configured, then i can change out batteries/motor later.
the MT2 project is still sitting here.. Andrew at CFR cut me out some test pieces to make sure the critical measurements were on.. they weren't, but only the rear diff didn't line up w/ the center brace. I designed a very small simple part to connect the two, and the design is now finished. the reason it's still sitting, is $. I got quoted ~$300, which isn't bad, but enough for me hold off on that project right now. in the meantime, I had bought a Academy SB Sport V2 4wd buggy to race with. I put the 380c-6l and 8 cells in it, and didn't even get through practice before both front and rear diffs were gone. It's now going to be sold. I went ahead and bought one of Andrew's $25 motor mounts, so I can run the MT2 at least with the stock chassis in the meantime, but have to find all the random parts for it that became scattered around my room during the design phaze :P

captain harlock, I've actually designed a 1/8 nitro converted to electric, but lost my work on that hard drive.. the problem, is I don't own a 1/8 onroad, and I've never even seen one assembled up close. I used the hi-res renders of a Serpent car.. the driveline on these cars are alot more complex than say a 1/10tc.. i guess i could buy/build one, and then get the measurements i need to design a feasable motor mount and chassis..

Serum, I know you know alot more about brushless than I do, but I'm not sure about your power recomendation. I've hit 75mph with a tc3 running a Basic5300 on 12 "sport stick pack" cells, and it was controllable even topped out in a parking lot.. on a prepped and banked track, I don't doubt i would be able to run 70mph around the track w/ the setup i had, and that included 6 of the cells being simply ziptied to the rear bumper. I think a 540c-9L on 16 cells won't have a problem supplying the power. I'm not sure if your familiar w/ Cliff Lett? http://www.rccaraction.com/articles/need_speed.asp His tc3 setup was 14 2400mah subc cells, and a custom brushed motor w/ a 12t armature and stronger magnets.. he hit 96.4mph. I don't see why a 540 9L on 16 cells couldn't run equal to that. I would only run this for about a minute or two at a time, I can and will overgear it. I don't need a tried and true power house, I only need ~1 minute of full power. also, multiple laps can be run, and i don't need to worry about accelleration, as i can be rolling accross the line at 90mph when the clock starts. the way they had the sprint run, he did three warm up laps to get heat in the tires, and get the motor up to temp, then did two "fast laps". first being 14.90 and the second being the new record at 14.3. I'm not saying your wrong, as you said "and that is the reason why you need all that power!", you'd be correct if I had to start from a stand still.
