Hi All

I have just purchased a HCA ARF AVISTAR 40 AEROBATIC 59", Before that i was learning to fly with a WORLD MODELS SKYRAIDER MACH II.

Anyway It doesnt come with a engine so im wondering what type of engine to buy for it does it have to be a engine designed for aerobatics or can i just get any .40 engine for it.

Thanks

I'm a fan of the Thunder Tiger Pro 46.
Cheap and strong & long run life.

G'day Mate,
What motor did you have in your skyraider.

The Avistar is fairly light and will fly like a trainer just fine with a 40 engine. With a higher performance 46 such as the OS 46AX the plane will fly fast like a sport plane at full throttle. My opinion on the best brands for these engine sizes are either the Thunder Tiger or the OS. Both are easy to adjust and run reliably. With the OS though stick with the FX or AX series. The LA are reliable but very weak running. All ways look at the next plane and see if the engine will work in that as well. For the price difference I would look at 46 size engines. The weight is pretty much the same but you get more power. What happened to the engine from the Sky Raider?? [8D]

Isn't the Mach II a low wing plane? I would imagine that would be fairly tough to learn on.

I suggest a ball bearing 46.

I can recommend (from personal experience), OS 46 FX/AX, Thunder Tiger Pro and Evolution NT. The Thunder Tiger and EVO engines are more reasonable than the OS and given proper care should last just as long. The primary difference between the Thunder Tiger and EVO is:

Thunder Tiger - needle valve on carb (angled back for safety)
EVO - needle valve on rear of engine.

I too have a Pro .46 and it is a surprisingly strong and smooth running motor. Like already mentioned, the needle valve is in the front and kind of scary (for me) to adjust with that big old prop spinning away so close to my fingers.

I have the GS-40 on my Avistar. It pulls mine around with authority, and is almost half the price of some engines mentioned above. I have an OS .46 FX, and its a reliable, easy to tune engine. But is it worth the asking price? In my opinion no. I don't have a TT .46 Pro, so I can't comment on that. The SuperTigre is a quality engine, and hey, for $50, how could you go wrong?

Re: "The SuperTigre is a quality engine, and hey, for $50, how could you go wrong? " < my experience:> finicky miserable engines to tune, probmatic carb barrel which will suddenly jam with the throttle stuck in one position, weak connecting rod. The engines have ok power if you can get them to run right but for an inexpensive engine the Thunder Tiger are much better. [8D]

If money's no object, then I'd go with an OS .70 FS or Saito .82 FS

But if it is, then get a SuperTigre G-51, you won't regret it and you can use it on your next model
