Between Hotwire and the Castlelink, my vote goes to the Castlelink. It's a bit easier to use (which is saying something, since the Hotwire system is simple as well) and I absolutely love the custom throttle adjusting feature.

I'll try and take a look into the timing thing. However, if the top end speed of the motor is any indicator of the output, then I think I just might stick with the Neu. From what I've seen, the Neu is putting out probably about 20% more power.

Thanks! And yeah...perhaps I should take the truggy and motor back to the lab for more tests first rather than just dumping it in to swim with the sharks. :)

Yup...smooth and crisp would describe it perfectly. Looks like the lag I have is all user error...damn.

and a MM Pro? That all of us should be so lucky... :)

I'll second that motion. Nice to see good straight forward feedback.

why is it the wrong motor? Why must it be a 2200kv at max?


When I first started ordering motors for the conversion, I think I was looking at the 2.5D AND the 1.5D. Figured I'd try one first and see how it went, so I cancelled a motor from the shopping cart.

Only to find out after the order shipped that I had cancelled the 2.5D instead of the 1.5D. I spoke to Mike as well and he said that the 1.5D would be fine, but just to be aware that my battery and gearing options would be limited. He also informed me that the 1.5D is an amp-monster.

So far I haven't had any major problems with temps in my set-up. :neutral: I mean, aside from just this previous race session, my electronics have been happy. Average temps (on an 11T pinion) for everything were as follows:

motor: 126-135 (no fan)
ESC: 130-150 (MMM v3)
batt: 105-125 (3S, 5000mAh, 25C) - the 125 is usually after a rather vicious bashing session

Now bear in mind that most times when we run the ambient temps are usually hovering around 95-96 degrees.

I could be wrong, but I think the set-up is quite happy. For this race session, I moved up to a 14T pinion...which would explain the higher temps. :neutral:

Am I misguided in thinking that the temps are ok?

thank you! Yes...I hope to stick around awhile too. I've been meaning to post up and stuff...I've just seriously had no time. :intello:

thanks, man. :great:

The neu was probably ok, was it a 1515/1.5d? I was refering to the tekin motor, the 2650 is designed for the buggy not the truggy, its even listed on tekin's site as such. The highest kv motor on the truggy list is the 2200kv, Size wise, the truggy motor would be better at handling the load

As far as the temps, you seem to be ok. I was refering to the tekin motor being a buggy motor, you even said it run a bit warmer over the neu, I think it was because it was a smaller (shorter, as in a 1512) motor than the neu

affirmative...the motor is 1515/1.5D/F. Don't recall where I said the T8 ran warmer than the Neu...in fact, the temp was lower. 123F, if I remember correctly. :)

I have one last test remaining for the T8...if she fails to perform, it's off to the chopping block for her. :diablo:

Or you could just send it to me! I promise you the punishment will be just brutal!!!!

You were right, I misread the temps. I still think part of the problem with the tekin motor, is its designed for a buggy, so less power available and less torque from the input

Well, we shall see. The T8's torture test will be this weekend. :whip:

If she cannot perform, then she shall be promptly kicked to the curb with a "For Sale" sign behind her.

aaah....I see! So...the lower the KV, the higher the torque and the bigger the can.

So if I wanted a stupidly powered buggy, then I should use a truggy motor in my buggy, aye?

Well, well...we shall see. Looks like I might hafta sell the 2650 and pick up a lower KV T8.

Alright...here's the weaopnry for the weekend:

Vehicle:
Hyper 7

ESC/Motor:
Tekin R1-Pro, modified with bigger capacitor installed and 35v UBEC
Tekin T8, 2650kv (sensor cable removed)
No fan will be installed for either motor or ESC

Pinion/Spur:
15t pinion, Spider center diff with 50-something tooth spur. I'll take a closer look tonight or something.

Tires:
HoBao Buggy rims, Losi Step Pins (silver compound)

Diffs: (most likely they will all be bumped up by 2K, but we shall see)
7K center
5K front
3K rear

Batteries:
PolyQuest 2S, 25/50c 5100mAh
ThunderPower 2S, 40/80c 5000mAh
NeuEnergy 3S, 25/50c 5000mAh
ThunderPower 3S, 40/80c 5000mAh
SMC Racing 4S, 40c (no burst or continuous was spec'd), 5000mAh


I'll let you guys know how it goes.

Hokay. So this weekend wasn't too bad. I got to run the buggy in another club main, and she did ok.

Correction to the diff fluid:

Center: 5K
Front: 3k
Rear: 1K

Spur: 46t Spider center diff

Ran the buggy on 3S (TP 40/80c 5000mAh), and she did alright. Also ran the T8 with out the sensor lead...seems to perform similar to a Neu. Didn't have too many problems with temps.

Motor: 142
ESC: 125
Batt: 105

Ran 2 10min mains. Not too bad, setup was still cogging a bit (a little more than the Neu). Power delivery is so-so. I ended up swapping out the R1-Pro for the RX8. The R1-Pro is a tough lil bugger for sure, but she's just not capable of handling the current draws of 4S. Either that, or my gearing was all out of whack.

But...overall, my observation still sticks from last weekend: I'll stick to Neu.

I also had a chance to run my X1-CRT in a couple of mains. I'm pleased to say that the RX8 didn't hiccup one bit on 4S and I was even doing well enough to place first in the three mains we ran. My mentor flamed out early, and I was able to hold my own against two Mugens and a X2-CRT.

The 4s (SMC 40C 5000mAh) is nuts...but interestingly enough, the temps were lower.

motor (Neu 1515/1.5D/F) : 125F (4s), 135 (3S)
ESC (RX8): 123 (4S), 126 (3S)
Batt: 4S: 105
3S: 120



SO...in closing, I am not too impressed with the T8 series. Perhaps I need to try a lower KV motor, but from what the 2650 has shown me, I am more incline to stick with the Neu. Although, to her credit, the T8 was an absolute monster on 4S in the buggy. First time I seen the buggy wheelie. Usually, with the Neu, I get nothing but wheelspin and paper plates. The T8 was a fraction less powerful than the Neu, which I think enabled the tires to hook up and loft the front end. Not too bad, but my vote is with Neu for now.


SO....anyone want to purchase a T8 2650kv motor from me? :neutral: I'll price it fairly. Open to trades as well.

I'm not sure what to think on that, running that tekin motor on a buggy should have been right, even the temps were higher. That is wierd
