Great system for the Losi nascar, this makes three of them with no problems at all
Just as easy as they said I got it and it was installed in my Losi nascar less than an hour later. Most satisfied I had been from an rc car purchase in a good while thanks AMain! Always taking care if the tinkerer.
Direct replacement and perfect drop in fit for Losi NASCAR kit, with the upgrade to brushless and programmable esc as a bonus! Much better than the stock components.
It’s going strong, don’t want to jinx it because I drive a lot but man 3s is crazy with 28t pinion.
All four reviews are from verified owners rating the combo 5 out of 5, and none report problems. Reviewers say it fits the Losi NASCAR as a direct, drop-in replacement and that installation took under an hour. One reviewer says it has held up under heavy driving and describes 3S running with a 28-tooth pinion as very fast. Others praise the brushless upgrade and programmable ESC over the stock components. One reviewer bought three units for their cars without issues. No disagreements or recurring problems appear in these reviews, but the sample is small.
- + Direct drop-in fit for Losi NASCAR
- + Quick installation
- + Brushless upgrade and programmable ESC
- + Durable under heavy driving
