Warranty Policy:
Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered!

Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following:
GMK Supply Piston Drill Set

I saw that too. I wonder if the stock status is estimated based on current order numbers. For example if there were no back orders it would be in stock next week, but with all back orders its next month.

who knows.

I was reading over the manual and saw that it says in the "needed to complete" section: MOD1 Pinion (TKR4171 ->TKR4190). That is a huge span!
I have a 3300 kv Pro 4 motor. Any recommendations for a good starting point on pinion selection?











never mind I found it on page one. I was searching for pinion...didn't think to try gearing

maybe someone can contact Tower or Tekno (not sure if they would give the info out though) about how many vehicles Tower actually was sent.

Heck this may kind of a good thing for Tekno, big demand and all, just hope they can fill orders lol.

No experience with that particular setup, but the range is to cover the different pinions available. If you look at their page, they do offer a 3 pack of mod1's, I'd start there.

I think people usually run between 15t - 18t pinions depending on motor and track size. I was running a 16t on my gen1 with a tenshock sc411 4600kv

I canceled my order and bought one from PowerHobby's Ebay store. Sure it's an extra $20 but it's arriving next Thursday.

The one piece composite diff cross pins don't seem too bad.

They were ever so slightly tight in the gears and so there was a very slight drag/resistance when turning the gear on the pin. Once submerged in oil and run for a bit they'd likely be fine.

I went with the aluminum cross pins (TKR5149A) which are still very light and had perfect tolerances.

While I'm sure the boys at Tekno have tested and tested the composite pins I went with the ALU pins. Perhaps the thought of plastic pins in a diff environment makes me uneasy.

I had no intention of using the plastic cross pins, so I didn't bother checking the weight difference with a scale. The aluminum pins felt very light.

be curious tekno's stance if a plastic cross pin fails if they will replace the diff gears. game to try them, but also skeptical too.
