i want to buy asp f61ar crankcase, why hobbyking have no stock?

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.

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 have been looking for a Four stroke 70-80 for a long time now and dont understand why Hobbyking doesnt stock them. I need a engine for Seagull models Ultimate-46 with the following specs: * Wingspan: 43 in (109cm) * Wing Area: 589 sq in (38 sq dm) * Flying Weight: 6-7 lbs Can someone please tell me if this engine would be suitable or not for the above model?

One of the reasons HobbyKing doesn't stock the 65, 70, and 80 four stroke, is because they are all basically the same engine in a nutshell. The all use the same crankcase and weight in at around 630 grams. The FS91AR weights 640 grams. A 10 gram difference from the others. I was originally planning on purchasing an FS80AR, but I went with the FS91AR and have been very happy with it. For your aircraft, this engine will do fine. Rule of thumb is, divide your aircraft size by two, and add that number to the existing size. 40/2=20, 20 40=60. I estimated your model to be a 40 size since it is the most popular. This engine may not pull unlimited vertical pulls, but it will chug right along.

I have the exact same airplane. I have had an OS 55AX, OS 70 Surpass II, Thunder Tiger 75 FS, and Saito 91. The Thunder Tiger 75 was not powerful enough. The OS 55AX was decent. The OS 70 Surpass II was good. The Saito 90 is the best performance of all. I don't know where the ASP 70 and 70 fit in relative to the OS 70 and Saito 91. If the ASP90 is not much heavier than the Saito 91, I would use that one. Just make sure you put a bigger fuel tank in the plane.

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.

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.
