Alpha Plus F850 'Club Racer' .21 Engine

Good entry race engine, it has a very linear power band so pretty easy to control. Decent but not overly impressive fuel efficiency. Takes a turbo glow plug, OS P3 are generally considered the best but Alpha do their own range too.

I've got an Alpha Z852 with a Hong Nor 2047 in my CLX, very quick and snappy on the throttle with great top end. My brother as a Picco .21 5 port, which although we haven't run side by side yet, seams to have a bit more bottom end, but once the revs increase, the alpha just seams so much quicker, the engine loves to scream  :yes:

I have fitted 1.1mm clutch springs so the lack of bottom end isn't noticeable now, it just takes off like a scalded cat.

Never used or seen a F850 so can't compare, but I'm more than happy with the Z852
