Losi Tenacity TT Pro SCT RTR 1/10 4WD Brushless Short Course Truck (Falken)
My new favorite go-to truck. I've run multiple packs through this rig with no issues. On 3S this truck is beast. I run 2S and it still has plenty of power. 2S also saves wear on the outer drive cups and keeps motor temps down. I usually run my Slash 4x4 in the same session as I run the Losi. The slash just doesn't feel as "dialed." You really feel the Losi racing pedigree running the TT Pro. It drives very similar to the DB Pro as they share the same chassis. Great handling, great air control, great power delivery. The Spektrum setup is awesome.

Worthy upgrades to fix steering slop:

- Exotek steering rack
- Up-graded servo and horn (I ran the EcoPower WP110T)
- RPM Rod ends with Hot racing pivot balls for OEM steering links

** The Traxxas Bandit receiver box can be used to house the Spektrum receiver

** I've seen bad reviews for oil leaking from diffs. Losi uses grease in their diffs. The model could have been sitting in the box before shipment for months, or stored on the shelf of a hobby shop somewhere. Oil can leak due to gravity or just simply from not being used. This shouldn't divert anyone from buying this truck. Most of my Losi RC's come with a little oil spot in the box. I've never had an issue with operation. I service my Rc's regularly and they always run great. Less cryin', more drivin'.

Worth every penny!
Lets start with bang for buck.
Aluminum shock towers, Aluminum shock bodies! 2 thing you don't need to upgrade. The transmitter and receiver cant be made any easier for this kind of performance! Its all auto tune plug and play. The step by step instruction make it easy to tune for your style of rally or race. 2s battery for racing and 3s for that bashing good time.
The LED light bar on the front is very bright and awesome for night time rallying! Everything about this short course truck has been made to be user friendly. Just follow the user guide and you'll look like a pro instantly!!
Cant wait to put it on the track and dominate my competition!

Happy Hobby Days

Love this truck!!! It’s very fast on 3s and it handles amazing when being compared to a traxxas slash or other short course style trucks on the market! I was very impressed how this chassis loves to grip the road but also allows you to throttle through turns and controllably break traction to start a drift without just flipping over and flying through the air on any fast turns. Very happy with my purchase and highly recommend! Build quality is top notch as well with the aluminum chassis and shocks straight out of the box. I thought that was a nice touch!
