Ofna .21 Pro JL

[Bkyd Basher]

Just wondering if the Ofna .21 pro JL would work and or be a good engine for a revo?

I'm interested in this too. It claims 3.7hp and 37000 rpm while picco red dot .26 claims 2.7hp and 34000rpm. Anyone experienced this .21 in their revo or other truck?

I would get the TRX 3.3 for the Revo myself... The Revo is a 4x4 Rig #1 / It's on the heavy side #2 / The power plant needs to be a good balance to produce good power to the wheel's & trans # 3..... So I would say the Ofna .21 would be OK to drop in the REVO but I think the Ofna will hurt the REVO's Performance overall.... If the RIG was 2x wheel drive I'd say GO FOR IT.....

I would do the opposite and use the 3.3 for a paperweight, install the Ofna .21 in the revo and have some fun.:

The TRX 3.3 is an okay engine, but the Picco, OS and OFNA engines are better quality and put out more power than the Traxxas mills.

The 3.3 is a .20 sized engine, so the. 21 will be better suited for him. Plus the 3.3 has known weak points, if you put a HD con rod, different carb, and better bearings you'll have a reliable engine that cost as much as an OS .21 without the performance. The 3.3 is a good expendable basher engine, especially if you send an old one in for the power up.

Actually... I have NOT experienced that problem in any of my TRX power plants yet... 1 of my TRX's Mills went back to Traxxas but only for a NEW Swap out I am hooked up with Traxxas Engine Replacment Plan.. Not a bad Deal for the money..... BUT THANKS FOR THE WARNING chickenman.....
