Amongst several well known brands of 2 stroke, I have several Fox's, but as Hossfly says, they are not for the "Plug and Play" man.

I got a heap of good info from the guys at: http://www3.bc.sympatico.ca/fliteline/

Once you have learnt about setting them up (and the rules are different for Fox's) they are o.k.

My favourites- the .45 Ring, (never had a dead stick from that engine) the .46 ABC (who said they don't do ABC technology- I also have a .40 ABC) and the .50 Ring.

The latter is a real stump puller.

I tune them all rich 2 stroke (they lean out once airborne) and use a mixture of synthetic and degummed castor oil in my fuel mix (total 20 % oil and 5 % nitro)

One other thing Fox will do for you. They will rebuild your Fox engine if it needs an overhaul, or rebuild it after a crash. And the cost is quite reasonable.
