REDS 721 Pista Gen2 GT S-Series 3.5cc (.21) On-Road (Pro-Tuned) Nitro Engine
I have the gen 1’s. X3. What a motor. In all honesty I’d overlooked these for on road for years! don’t!! Typically they have moved on and made small adjustments to make this spec even better.
Having raced ic 1/10&1/8th since the mid 1990’s. I can honestly say that I’ve probably bought and raced most models, specs and variations available.
The reds have stood out for me, from the moment I initially started them all, break in was a pleasure! As is racing them!

Once i’m in a position to purchase a spec/gen2 i’ll be doing it, because i hear from my colleagues overseas that they are even better! I find it hard to think how they can be?? But will do my best to experience it. Once again REDS. Amazing product! And of
Course a massive thanks as ever for amain for
Supplies, which are always on time, as described and amazing to use.
