1. From what I gather, I would need a servo with at least 300oz of torque. Anybody have the Protek 170S?
2. it seems a lot of people like 2000kv truggy motor, but I have a 1900kv T8 buggy motor. I would be using 4s batteries. Will this be a good enough motor with an RX-8?

Matt Wolter was running that motor in truggy last year at AMS 4.0.

Guys running a 15t without sanding down the brace is a fine mesh?

I started with a Protek 130t and switched out for a 170S. I have to say it is the most badass servo I have ever used. Totally overkill on 7.4. I want to put one in everything I drive. Some will say it makes your truck twitchy due to the speed and torque but it's exactly how I like it. After I ran through a pack at the track I went inside to run my SCT410 with a savox 1258tg which is supposed to be fast and I was running into walls getting used to having to turn so much earlier. I have since put the 130t in my SC and prefer it over the Savox. I have not had any issues with my 2 Protek servos (knock on wood) and will buy more in the future if they proove to be consistand and durable.

Perfect mesh for me with a 15t.

I had to sand my brace, the 15t pinion would only partially mesh for me.

A longer screw. the stock screw is a M4x10mm (TKR1443 on step L-3 page 18 of the manual). This only leaves a tiny bit of thread left in the case and the team is pretty sure this is causing it to break.

Many of us run a M4x14mm. I noticed it almost pops into the rear case but still clears everything. May want to try a M4x12mm if 14 makes you un easy.

I think the included Tekno plastic horns have gotten a little better, but I wouldn't bother with them and just go ahead and get an Aluminium horn.

Other than that I think most are running more like 15-20-5 in the diffs vs. stock, otherwise handles great out of the box and then tuning for personal pref from there.

I personally took a few turns of droop out of the front and stood up the shocks in the rear a bit to tune out some push exiting turns, but otherwise still running stock.

my body is THINNER than a touring car body!!!

munrath 05-21-2014 09:44 AM

I shoe goo and tape all my 8th scale off-road bodies.

mamdot91 05-21-2014 09:54 AM

Quality of body seems like the one from my mini 8ight body. Or maybe that's even better than this ... Lol.

Mizchief 05-21-2014 01:00 PM

I have a couple of cracks but otherwise is ok after 2 race days. I definitely need to tape and goo it to last, but using Velcro on the bottom forgoing the clips has helped a lot. That lets the body be supported from the bottom and has a little more give.

I just bought a one race old ET48 from a friend of mine. Got a smoking deal on it RTR with 4- new 4s batteries. It has a 1700kv Tekin truggy motor on it with a Gen2 RX8. Has anyone else ran this motor? My other truggy which is a non Tekno I'm running a 1550kv motor on 5s and get 17 1/2 minutes run time. What kind of run time would I be looking at with the 1700kv? Just wondering in case I have to run with the nitros and might need to make a battery swap.

I'm going to change to a 16t and run 2x SMC 7200 2s and think I'll have plenty for a 20 and can take a practice lap an not hold back.

I used the 7200 x 2 in practice for 34min !! In the main I did 3 practice laps and the 20min easy. The next day they ran for another 4 minutes on the stand.
