New to RC and haven't even received our TT-02 kit yet. Does the following look like a good choice for a servo and is 120deg enough? It is a JX PDI-6208MG

Dead zone: 2μs
Maximum pulse width: 900-2100us (suitable for remote control)
Maximum angle: 120°
Motor: iron core
Working voltage: DC4.8~6.0 V
Speed (4.8V): 0.09 sec/60°
Speed (6.0V): 0.07 sec/60°
Torque (4.8V): 6.8 kg.cm
Torque (6.0V): 8.2 kg.cm
Size: 40.5X20.2X38mm
Weight: 55.6 g
Bearing: 2BB
Cable: JR 265 mm
Output teeth: 25T (Futaba universal)

Car is dialed...running on outdoor asphalt...35wt oil ft and rear. 1.5mm shim inside shocks f+r. shocks all the way in on front and all the way out on rear. HPI tires front and rear...Vintage tires...5.5 ride ht front ...5.0 in the rear. Calms car down...Added the 3Racing oilfilled diff in the rear with 1000wt oil and a 3racing spool in the front. PF mustang body.....I use Savox servos. 1251mg ..59.00 from the bay and fast and strong.....Also use the yeah racing adjustable motor mount, the one with the slots not the holes and usa a 82 t spur and a 51 t pinion in 64p. 6mm hub in rear 5mm hub in ft....1.5mm toe out on front 3 deg toe in alum hub on rear.

The sweep - 120deg - isn’t really that unusual for an entry level (and some expensive!) servo and not issue.

don’t expect it to be amazing and actually meet the specs below (which are also fine in theory) and might not last that long - it’s a cheap servo.

Thanks for answering my question.

Nope the rears will not work since the TT01 upright is wider than the TT02 so will not fit in the TT02 rear lower arm. You can probably fit a TT02 rear upright onto a TT01, you’ll just need to add spacers between the lower arm and the upright.

The front TT01 steering knuckles will fit on the TT02 suspension, but they are shorter so it will change the angle of the upper and lower control arms, thus affecting your roll center. Remember the TT02 steering knuckle needs a spacer above or below it to keep the arms parallel to each other.

Thanks. I'll see if I can modify the TT01 uprights to make them fit the lower arms. Think I can trim down some plastic material on it so it becomes narrower.

What are you trying to achieve with the TT01 uprights? You don’t have the correct TT02 uprights available?

I just want to have the option of running 5x11 wheel bearings. 5x10 bearings in the TT02 uprights still work fine for me. Just want to try something new.

It looks like my TT-02 will need to go through a full teardown and rebuild. I had a high speed crash a while back and just now realized that the impact was so hard that the motor mount hole in the tub chassis is destroyed. The diff cover is also cracked so I'll be inspecting for other possible damage when it's torn down. It hit the curb head on @ 35+mph. Completely my fault. It was still all in one piece and still drivable afterwards, which I didn't expect it to be. Since I am planning to do a complete inspection and rebuild, I also plan to take this opportunity to attempt making it my 1st dedicated rain/wet car with stainless steel hardware, stainless steel bearings and all waterproof electronics.

Ouchie!

Thankfully, these are inexpensive kits to work on.

using 42102 TRF dampers, with standard length spring, no way I could get 5mm & 5,2mm ride height
Changed the using short springs (for M chassis dampers), yes... got the ride height.

Just came across this oil filled differential kit made by Yeah Racing. https://www.rcmart.com/yeah-racing-o...t-020-00104972

Wonder how well it works compared to the one made by 3racing and the Tamiya one.

For those using tam 54874 upper arms, I designed droop limiters for the TT02. If you want the .stl file for printing, PM me.

Oooh, that's a good design. Nicely done.
