Recommended KV for a Hyper 10tt?
 
Looking around trying to figure out what KV motor to get. Its going to be a Castle system, this will mostly be used for track days. I usually hit the track up on Saturdays and open practice is from 11am to 8pm. Sometimes I stay the whole day so thats ALOT of running.

I would rather go with a lower KV motor and run higher voltage than a faster motor and have to run good batteries

My Mini 8ight has been great about it, nothing has worn out yet except for the foams inside the tires. There have been broken parts, but no parts that have worn out and I probably have about 50-60hrs of the buggy so far and I've only owned it since January.

Anyone with a Hyper 10TT or a Hyper 10SCT have recommendations? I am not a racer and am not beholden to any class. Classes mean little to me.

where are you racing buffalo grove local ? Can't help you with 1/10th stuff, too small for my ballz

Your 1/8th stuff wouldn't be welcome at the track I visit most often. Mine isn't.

"Too Big", "Too Dangerous" are the phrases most people talk about. A 1/8th vehicle driven by a proven driver is safer than a Slash VXL driven by an idiot.

Oddly enough, despite its crazy size, when I was able to bring my Truggy to the track it was one of the fastest things on the course even paired down to 3S on a MMM 2200kv setup. It was just so smooth and easy to control. Some of the corners were tight requiring full steering lock and braking to get it to rotate but I miss having it on that track.

Might want to look into a 2700-3300kv motor on 3s for that. Unless you were wanting to run 4s or higher.

I've raced a 10sc with a cc2650 on 2s but switched to a 3s 2000kv(medusa) setup after puffing a undersized 2s lipo with the 2650.

That was before the castle 14xx series came out. Now I would use the cc1410 3800 for 2s to 3s or the cc1415 2400kv on 3s to 4s voltage.

How about a 2650kv on 3S or similar motor made for 1/8 buggies. It will stay cooler longer having a larger rotor. I run a 2650kv Tekin with a mmp on 3s in my Ten T and it's great. I bash it pretty hard and no worries. No heat issues and I have a lot of flexibility as to gearing. I am of the belief that put in more motor than you need so as to never have to worry about it.

brian015 04.10.2012 07:56 PM

I run a tekin sc4x 4.5t (4800kv) on 2s with a mmp in sensored mode - very nice.

I just ordered a castle 1410 3800kv and a SV2 for my hyper 10tt which should be here tomorrow. Right now i only have some 2S 5000mah 20c to try out, but i plan on running 3s in the near future if it's not gonna be enough juice for me.

I also have the optional heatsink w/ fan mount on it that im gonna try out when i put it together, hopefully i can let you know how it goes in the next couple days

See, I already have 2 2S and 2 3S packs for my 1/8th truggy which runs matched pairs of batteries in series.

At the track I run the 3S as parallel packs, and the 2S in series for 4S. I however don't get to run this truggy as much because there aren't many tracks around here that will accept it.

Hence the 10TT is coming in to fill the niche, my Mini 8ight is simply too small to handle the track, its not smooth enough and the mini bounces all over the place. That and I get smashed by SC trucks driven by less experienced/careful drivers. Getting tired of buying parts for the 8ight.

I'm thinking a MMP 3800kv setup might be my answer. I wouldn't mind a few blasts with a 4S pack for speed runs though.

nitrostarter 04.11.2012 06:58 PM

With your battery setups available, the 3800 should be perfect for that setup.

I recently tried the Sv2 and CC 1410 in my hyper geared 15/46 (46 is stock right?) It was surprisingly...slow. Motor was 85 and esc was 150, I don't think i have much wiggle room for gearing for more speed at this point.

I suggest getting the MMP or a better esc that can handle 3s normally better than the SV2 can. Ive read and seen nothing but problems with the SV2 and SCT esc's on 3s.

brian015 04.21.2012 08:15 AM

Yeah, my hyper 10tt gives the mmp a workout - I wouldn't use a sidewinder in it.

CerberusVI 04.22.2012 02:00 AM

What kind of gearing are you running? I plan on purchasing a mmp and some 3s lipo's and was gonna try 12/46 gearing. 2s is too slow for my track and my lhs

brian015 04.22.2012 07:47 AM

I'm running 2s with the 4800kv motor and a 18t pinion - it's plenty fast.

Thirdgen89GTA 05.09.2012 01:49 PM

Welp, its all up and together now.

Went with the MMP / 3800kv system. Initial impression on 2S was too slow for any type of bashing. Horribly slow in a larger open area. But 3S felt okay. That was with a 14t pinion, I stepped up to a 16t and it was better, Temps are very happy on 2S and 3S with the 16T pinion.

Different perception at the track! The problem was the tires simply spun in the med. length grass. On the track the 2S gets up and goes and is plenty good for the small track I run it on. Can get ham fisted with the throttle and its never too much power. I do however want more power for those "power to pass" bits. There were times I simply couldn't set it up right and overtake cars by using a better line. It just lacked the power to do so. It really begins to shine on 3S though, there is enough power that you can visibly see power getting wasted on ballooning the front tires. I'll have to play with the diff oils to see if I can find a happy medium. its possible the diffs are simply greased right now. 4S is out until I sort out its power delivery, all of it would be wasted on the front tires anyways.

Steering is good, it holds its line well, but I want more turn in out of it. It pushes too much on the stock setup, I'll experiment this weekend at the track. To get the nose to dive into the corner I have to get off the throttle and dab the brake to get the car to rotate. I'll have to play with the suspension to see if I can make it turn the way I want. It could also be the tires, they are just straight up pin tires.
