i want to buy asp f61ar crankcase, why hobbyking have no stock?
Lawrence  20 points - 5/27/2015
Why is the .52 F.S. 5 gm heavier than the .61?I really would like a slightly smaller version,the 30F.S. is a sweet little motor,perhaps they might become available from H.K.?

Could try Aliexpress for the ASP30FS they do have a supplier on there.
 Glyn R 108 points
The 52 is heavier than the 61 because they use the same crankcase and ancillaries. The cylinder liner in the 61 is thinner than than the 52 to give bigger bore. This reduces the weight. This is is common in lots of engines. The Irvine 40/46/53 2 strokes are identical externally but the 53 is lighter than both the 40 and the 46.

I actually have a os 50 2 strokes mounted on my plane. Could I use this engine or I use better the ASP 91 four strokes engine? Thanks
 Lawrence 20 points
A .50 2 stroke will certainly be a lot faster if speed is what you want.The .61 is a great engine for cruising around in a nice realistic manner,I have a 60 " Ryan s.t.a.which is perfect with the .61F.S.

I bought two of these engines , both started straight away and run perfect even down to a low idle using 10pcnt nitro - plenty of power using a
12 x 6 propeller and economical on fuel.
smooth transition from idle to full throttle.
i am very happy with the motors for the price.

This engine is out standing. It started on the first try, no problems. It was pre set from the factory so I didn't need to do a lot of adjusting to it. It's worth the money believe me.

Wow! super engine. I use mine in a 40 size low winged trainer. Plenty of power, easy to start and running clean. Would recomend this to anyone! Perfect to use later on a 40 size acro plane too. nice!

Great engine - very happy. Make sure you prime it until it is literally soaking in fuel and then it starts easier than any other engine I have come across. With a 500cc fuel tank I get around 15 minutes of mostly full throttle running a little on the rich side with a 11x7 prop.
