G'day

The Skyraider Mack 2 is the "hack of choice" at my club. It weighs in at about 5 pounds and has 556 square inches of wing. Most are powered by OS 46AX engines and they go like stink to the point of fluttering their elevators and ailerons. But, one bloke has one with an OS Surpass 48 like yours. It happily chugs around. It is not as fast as the two stroke powered models but it flies really well though without unlimited vertical performance.

The plane you are talking about is 6 pounds but if it has a larger wing area, then it could fly quite well with the 48 but just don't expect it to be really fast or to go up forever.

I also have a number of Sig Kadet Seniors. They have wings of 1150 square inches and I have successfully flown them with the older OS FS40 which is far less powerful than the 48 Surpass. Your 48 would fly one of them really well.

Once upon a time, many years ago, I had a 48 Surpass which I put in a Thunder Tiger ARF trainer. Everyone told me it would not fly well. They were wrong. And when they flew it, they were amazed. It was no rocket ship but it was steady and would do the things trainers are supposed to do and a few more besides.

It will fly your plane. It won't be a rocket.

And as for four strokes being difficult to use, I find them far easier than two strokes. My Saitos, Enyas and Laser four strokes are extremely easy to use and quiet and economical to boot.
