Hi folks,
 Although having been keen on trying a 4 stroke set up for a while I have been holding off as I couldn't really justify the expense.

 My lhs is having an after christmas sale offering 20-50% off everything in store.
An O.S .52 surpass has been residing under the glass top of their back counter for quite some time now and it looks like the owner will let it go at a fair discount.
 
 I assume that this engine should be quite happy in the .49-.60 size airframes which is to be my main focus from now on.

 The price listed on the box is $299 Aud but I suspect I could get it for around $220ish Aud or about $185-$195USd.

 Does this price seem reasonable and does anyone know of any problems using the O.S .52 for stunt?

 Any thoughts or advice greatly appreciated.

 Thanks in advance, Rob.

Rob,

I don't know about the price, but the engine ran fine for me in an old 60 size Time Machine. There is plenty of power and if you like the typical four stroke stunt run, you should be happy.

FWIW - O.S. has discontinued the 52 in favor of a newer 56 "a" model. The "a" series has a redesigned oil system which eliminates the crankcase breather. I haven't tried one yet, but they have been making better and better engines each time around (with the four strokes). 

The Saitos should be nice also. I'm still playing with my old 56 and 72.

Take care,

Ron
