Losi Tenacity TT Pro SCT RTR 1/10 4WD Brushless Short Course Truck (Brenthel)
Straight out of the box incredible. Not being built with the extra weight of a big plastic inner roll cage allows this to handle without flipping over. All aluminum shocks are awesome. All aluminum skid plate and shock towers. This this is fast and handles awesome. Definitely high quality. I find the quality out of the box better that the Baja Rey and Hammer U4. The Tenacity ttPro is just so solid. You will know when you open the box. I did read the reviews of center diff leaking. I did not have this problem but AMain is awesome to work with so even if I did they would take care of it. Anything can happen. I would give this 10 stars

I have had this truck for 9 months or so and I would definitely recommend it, the truck is awesome. It is obviously based on the Tenacity platform and is thus pretty much the same as the DB Pro which I also have. This truck is plenty fast for me on 2s, I have not run it on 3s. Although I have ran my DB Pro on 3s and it is bananas, I imagine the SCT version would be also. Compared to the Arrma Senton, this truck seems higher quality and handles much, much, better, which it should since it is more expensive. I am not sure what more to say, the truck seems durable, although I have not sent it to the moon, that is not my style. I guess I would say if you just want to bash and don't mind the exceedingly ugly looks, save some money and get the Senton. However, if you actually want to do more driving and or racing in a realistic looking RC, get the Tenacity TT Pro. Losi is definitely my favorite brand, they make realistic looking, awesome handling, durable RCs. I am not into psycho paint job weird RCs that have no basis in existing life size cars/trucks.

I'm not reviewing this yet. But I did have oil coming from my diff too like the other review. I haven't taken it apart yet..

Edit: so diff screws were a little loose causing the leak. I added diff fluid and reinstalled. Not a big deal but it would have been for a newbie. This is a solid platform. You can't go wrong with it. I bought this from Amain using a $180. coupon. For $320 it was a steal.

My vehicle arrived with Oil all over various parts of the vehicle and drenched the underside of the body. It appears that it leaked out from the center differential. The more I look at it, the more oil residue I notice on parts. This will be a dirt magnet on all those parts. I am still waiting on a further response from Amain. ?
