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

[magman]

This will go in my Revo....so I can't decide which one to get...on 6s the 1550 will probably be a tad more efficient,but, the 1700 will be faster...decisions, decisions

[BL_RV0]

1550 gets my vote.

[magman]

I added the 1350 to the list of possibilities

[brushlessboy16]

also going with the 1550. should be really nice sensored :)

I can't wait to finish the truck and put this new system in it

I would opt for the 1550 or the 1700 on 6s. 1350 seems a tad slow IMO.

Yeah it will be a tad slow...I am leaning toward the 1550 on the premise of being tad more efficient and not a lot of speed loss

I really don't get why people have a problem with faster motors and efficiency being lower. The efficiency curve of most motors is pretty high up to the last ~20% of the rpm range from what I've seen (Griffins program). Actually, too low of an rpm is less efficient.

True..I am just trying to be too conservative I guess

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

Any of those motors will be fine and all about the same eff wise. Its just depends on how much spd you want out of it. Even the 3D will be plenty fast unless you are building a 60mph street rocket. 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.

whats your running style?

if you will be doing any serious racing on a track I would go with the 1.5y model w/6s, I am looking at the 2.5d
