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

BL_RV0 03.20.2009 10:27 PM

1550 gets my vote.

magman 03.20.2009 10:28 PM

I added the 1350 to the list of possibilities

brushlessboy16 03.20.2009 10:35 PM

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

BrianG 03.20.2009 10:58 PM

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. :neutral:

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

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.

whats your running style?

suicideneil 03.21.2009 05:24 PM

One foot in front of the other?..

I'll get my coat..

Bashing...but may do a tad bit of racing w/friends...I am leaning toward the 1550

I'll get my rc's and meet you there!:mdr:

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

No serious racing....just bragging rites racing

Finnster 03.21.2009 10:37 PM

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.

hootie7159 04.23.2009 07:05 PM

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...

E-Revonut 04.23.2009 08:15 PM

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!

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.

hootie7159 04.23.2009 11:08 PM

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
