New hi-speed project

The car is very similar to the GTP in design. Plus it has a two speed! I am only trying to get to 70mph, but I can gear up if needed. You should have fun with it, my 10th scale tamiya that can do 80 is a blast, body choices will be critical, downforce and airflow management will be a big concern.

Actually, I was looking at that project a while ago. I liked the way it was built, but not sure how easy parts availability will be at my LHS. Of course, I could get them directly, but sometimes it's just easier to call up the LHS and tell them to get it for me.

I understand about parts. I have bashed the snot out of my ofna mbx buggy (identical mostly to the gtp) and it has never broken, only the front bumper cracked. I only bought the Yusa cause it was under 100 bucks shipped. I doubt that i will break anything, these vehicles are so solid being based off 1/8 scale buggies, almost indestructible! And the wear items will interchange, such as diffs, etc.

Are you going to use a clutch, or one of mike's lst 2 pinion adapters?

hey BG, how about you use lutach's 200a controller when it comes out or maybe a CC HV110, and a neu 1527 1d (2160kv), and 12s 25c lipos (polyquest)?
esc: $270
motor: $433
batteries: $776

how does $1476 for a setup sound?

I agree that HV is the way to go. I am going to order a great planes 60amp hv esc and the programming card. I will try it on my tmaxx first, 10s lipo on a 20xl feigao should be ok, do not think it will overdraw the esc.

Brian, the use of smaller batteries and more cells would probably be cheaper. I have seen 15-20c 2100mah cells go for $10-$15 per cell. And I am sure that a 12s2p setup of those cells would be able to get you about 4hp. Run that thru a decent hv esc, castle, knotronic, etc.

I am actually reconsidering a hv setup for my yusa car. I will test it on 4s with the 2600kv motor, but may sub in a 1300kv and run it on 10s lipo?!?

I agree on parts availability, usually there are one or two parts that break fequently, so you would end up with quite a few rollers!
