Brushless motor turn suggestions

[HotRod716]

Hello to all:

I am getting back into the hobby after 25 year hiatus. I am giving my daughter a sc10 (brushed rtr) and I thought it would be great to go to the local track, short corse with many tight turns, and run my old Kokomo. After reading up on here and many forums, it is a 870c with a upper plate, RPM front diff housing, I do have a tcs installed along with the rc-10 spur conversion. I bought this car used back in 1988-1990, cant remember. I will post pics as soon as I get cleaning it I promise.

This leads me to my question: What advertised turn on a brushless motor would be good for this car? I am going to run lipo batteries, have the conversion plate on the bottom of the chassis. I have an Orion r10 ESC. From what I read 8.5t is for most 4wd, I am leaning toward this direction. I could de tune it a bit until my driving skills come back to form. I'm just not to sure, however. I would appreciate any suggestions and ideas you may have. The surface is a higher grip hard clay surface. Thanks for your help.

Reedy/Velineon/Castle 3300-3500Kv on a 2s lipo 5000 mAh 50c will rock your socks and be reliable


I would pair it to a Vxl-3s or Sidewinder 3 ESC

I would put the old girl out to rest or keep a very mild stock setup in it, a stock hobbywing with a 21 turn would be enough a cheap enough and fast enough.
pick up a newer model car for the 8.5 turn, a Tamiya DB01-RRR is bullet proof, very robust and extremely agile.

I run an 8.5t in my Works 91 with tcs with no problem at all once i'd rebuilt the diffs. Biggest problem i encountered was lack of weight, the old Yokes are very light compared to todays cars and there's a big difference between the old nicads and lipo's. I waa adding weights all over to aid traction. But SO much fun to drive, look forward to seeing some pics of your 870.

Thanks for the replies. I'm going with a trinity 13.5t and see how it goes. I have to wait until Christmas before I can tear her apart. Have to hide this car from my daughter so she doesn't suspect anything.
