Perfect power, a little more then the speed and still great run time, I would highly reccomend one. My son Dylan loves his.

What kind of run time is he getting out of his o.s 25 and what pipe is he running with it?

I bought one a while back and installed it on my Kyosho Inferno GT2 onroad car with an OS 2060 pipe (perfect combo IMO). For run time, still haven't checked it out yet.

Were running os 2050 pipe and depending on the track and finger pressure we get from 9-11 mins of run time. Side Winder fuel
