With Tekin's new system...for 6s on a Revo, 1700kv, 1550 or 1350kv

No serious racing....just bragging rites racing

For some reason I read this as Tekno's system at 1st.. lol

I would be inclined to go for the 13xx or the 1550 (for a touch of stupid) if you are mostly bashing w/ friends. Should be interesting to see how these motors do.

I just got the 1350kv for my rc8t.... (backordered from amain and now its in!!!) and i'm running it on 5s geared for 41-43mph on a big track....just looking for the least amount of heat...the most amount of torque.....and consistency...

1350 is def a tad lowin the rpm range on 5s. My 2.5d(1650kv) is decent on 5s but something around 1700-1750 would be better IMO. On 6s I vote for the 1350 or 1550 if you want stupid speeds!

Here's the guy from Tekno running a 3D on 6S iin an 8T in truggy class and destroying everybody. BL motors don't need massive rpms to be fast. I'd make my decision on desired speeds rather than minor eff differences.

thats plenty. thats actually what I run in my e-revo and its more then enough. Right now I plan on running 1400kv on 6s in a hyper 9e. Was actually going to run it on 5s but neu had a good deal on the 6s pack so thats what I ordered.

well...after ready through this thread again.....and using the speed calculator...i cancelled my order from amainhobbies..............and re-ordered the 1700kv combo from the axiom website!!!!!!!!! yay!!!..had to order both separately $369 total....only $10-$20 dollars more that most websites....AND they are going to be shipped out priority!!!!!

My main thing with low kv is the less restrictive gearing, especially with these bigger 5mm shafts. I might not be able to buy 4 pinions (i use only mikes) at 15.00 or so apiece, the lower kv allows me to settle for something not necessarily right but i won't burn it down. I plan to try something, I have a 2250 lehner 10t motor (1184kv) I plan to put this in a 8T on 5s for starters, i only have a quark 125 that has a chance to run this beast right now. In my twinforce, center diffed (51 tooth mod-1) with 1/8 buggy gearing the motor can pull a 19 tooth pinion, I figure with truggy diffs, i should be able to do the same easily on 5s and eventually 6s

Another thing, I have a bad habit of taking a path less followed. if someone recommends something, I have gone another route, not to insult them, but that's the established route, I look for different options. I guess it comes from my slotcar days, People wanted rpm's, I wanted torque
