I just picked up a few more upgrades for my TR-SC10E project including a Tekin RX8 Gen3 ESC, Tekin 4300kv motor, and a Protek 170SBL servo.
Also in the picture above is a FlySky FGr4 receiver that I'll be installing for use with my Noble transmitter
Here's a quick look at the 170SBL servo installed. This servo is substantially heavier than the Savox 1267SG that was in the truck but it appears to be well constructed. The servo itself was a straight forward install. I did notice that there is potential for the servo to move should the mounting screws ever become loose so I may use some servo mounting grommets in the future to take up some of the space between the screws and the servo tabs.
I also installed a Protek 7819-BK aluminum servo horn but I'm not sure if I'll actually use this one or not. Because the horn is designed to be low profile, the servo linkage ball stud was touching the top of the receiver box. I had to move the ball stud from the bottom of the servo horn to the top. This created a fairly dramatic slope to the servo linkage. I'm not sure how this will effect the truck's steering geometry so I'll likely see what other servo horn I can find that is a closer match to the stock plastic one.
I also took this time to mount a transponder in front of the servo.
The Tekin RX8 was a perfect fit for the TR-SC10E's ESC tray. It's almost as if the truck was designed for this ESC. I purchased a black case for the RX8 but when attempting to remove the white case, I stripped two of the tiny phillips head screws on the bottom of the case (I was using a 30 year old junk screwdriver). I suppose if I tried a little harder and perhaps purchased a new screwdriver, I would have been able to get the screws out but I decided to just use the white case for now. Compared to some of my Hobbywing ESC's, the Tekin is a little ugly looking and I definitely don't like the cheap on/off switch but I'm sure the performance will be good.
Here's the Tekin Motor installed. While I was installing the motor, I also added the aluminum center diff mount and cam style motor mount. The aluminum diff mount will help ensure everything stays where it should and the cam style motor mount will make pinion gear changes much easier. I'm not super happy with where the motor tabs are but the combination of cam style motor mount and where the holes are in the motor didn't allow me to put the tabs on the top as I would have preferred.
Here is everything wired up. I'm fairly satisfied with how it came together. I may make a few more minor adjustments but I think the truck is now ready to hit the track.
Notice that the servo horn ball stud is now on the bottom of the servo horn. The servo came with some shims that I added under the servo to raise it up just enough that I could return the ball stud to the under side of the servo horn. I'm still not 100% satisfied with this arrangement but, I think it will work.
Also, the FlySky FGr4 receiver fit okay in the receiver box bit it's about 1/8" too tall so the servo box lid doesn't fit as snuggly as I'd like it too. Other than dremelling some material off of the top of the receiver and from the inside of the servo box lid, I'm not sure how to improve this situation either.
That's it for now, I hope this helped you with your TR-SC10E upgrades. By the way, you can do me a HUGE favor by purchasing your TR-SC10E parts and hop-ups from me and also by using my Amazon link if you make any purchases at Amazon (they'll pay me a small commission)
