I'd leave it the way it is. IMO, unsensored is more reliable, runs cooler, and longer... It just doesn't work with every setup.

As for the slop, without even watching the rest of the video, I'm guessing it's on the upper control arms. Almost looks like there could be another shim on the hinge pin. You would need to file the upper arm to fit one in, I think.

That said, a little bit of slop is good, especially for a high speed car. You don't want the steering to be too twitchy, which is what will happen if that little amount of slop was gone.

Edit: Your servo horn is moving. That's not slop. Nothing should make the servo move except the input from the controller. Something going on there for sure. What servo is it? Is the horn tight?
Thank you for the input. I figured it out as well that the cheap solar d771 has some play. My ofna aluminum servo arm is tight and tried to use the servo arm that came with servo, there is play as well. I haven't ran my car yet. Will this cause any problems? Should I buy a savox now?

It won't move like that on the ground.

But for 70 bucks... The 1256s are real nice. That is what I am running in mine.

Cool. Thanks. Wouldn't the 1258's be a better choice though?

Ya know, I'm not 100% which one I have in the car. I own four of them, two in my truggy, one in my SCT and one in the Ofna... ha ha.

Either the 56 or 58 will work. But yeah, the 58 is all you need. Burt even with half the response time of the 58, the 56 will still feel plenty fast, and more than enough for an 1/8 GT car. In fact, a little slower servo will prolly make the car easier to drive, on the track and for speed runs... Again, less twitchy.

Hello all. Just wanted to share a quick video of my new GTP-2e that I took out for the first time today. I owned several RC's in the past but never had an onroad vehicle. I don't really know why I waited this long to purchase a vehicle like this, in addition to being a 1/8 scale. Or in other words, I have been missing out from all this fun, having only 1/10 scale in the past.

Thank you all for your comments and suggestions. I just have a simple setup which consists of budget electronics, no Mamba Monster, Tekin, or high discharge lipo's:

Tenshock X802 V2 2100kv 6 pole
Hobbywing Xerun 150a ESC
Solar D771 Servo
Two SMC 2s 5000mah 40c / Two Duratrax Onyx 3s 5000mah 25c
19t pinion 51t Spur
SupraSales Wheels/Slicks

It has been a blast for me so far. I have never had this much fun in this hobby considering this kit is less than $200. Well, I plan to gear up to 25t for my next run and probably take it to the track in the near future.

Here is a quick video. If you turn up the volume a bit, there is some old school music for you guys =)

Edit: I didn't have my GPS on hand today. What do you think is the estimated speed on 6s based on the video? 50-55 mph?

pop your data into here, will give you a great idea of where you can be as far as theoretical top speed.

19/51 on 6s (@3.7v/cell) shows about a 67mph TTS.

Its simple. everything you generally need is in the drop downs.
The numbers at the bottom aren't the most important and i don't even use them. (im a basher so im not that particular and they don't change the totals by a whole lot anyways)

The big ones are the voltage, i use it at 3.7 nom v/cell. and tire size.

It does not really matter... It is hauling pure azz.

Ok just wanted to share that I was able to run it with a 25t pinion and stock 51t spur, and 6s.

Just to give you an idea, I was going around 55mph with 4s and 73mph with 6s.

Mine clocked in at 46 mph with my iPhone strapped to it.

Track Star 2650, 3 cell, 18/51. Plenty fast for the track we have. All my reaplacement parts are in, so I can put it back together. Putting a center diff in, prolly run 15K in it. My Mugen is so easy to drive on our track with 5/5/3... Shoot... might put 5 in it.

I think I need to soften up the rear too. Oval shocks are a little too stiff. Or maybe I'll just bump the toe up for some more rear grip.
