Default Seagull Spacewalker with OS 40-LA

Seagull Spacewalker with OS 40-LA

I am thinking about buying a Seagull Spacewalker and flying it with an OS 40-LA. The weight is listed at 6-7 pounds, is an LA-40 big enough to fly it, that seems like a lot of weight for a 40 size sport engine. I fly a Tower Trainer with an OS 40-LA and it takes a good long run to get it in the air. I weighed it and it is only about 6 pounds with a flat bottom airfoil.

Thanks

Default RE: Seagull Spacewalker with OS 40-LA

propjobbill - Although I didn't use the OS40 engine, I do have a Seagull Space Walker II with an Evolution 46 engine, and yes, (depending upon what you want from the model) the Evolution 46 was about as small as I would have wanted in the airplane. Although I could do loops and rolls, etc. I would have preferred a little more power in the air at times. The take off roll wasn't bad at all, but it was a bit anemic in the air, not much of a vertical. You have to understand, to a point, I prefer to overpower my airplanes and fly at 1/2 to 2/3 throttle except on up lines and down lines. It would fly nicely at 2/3 throttle, and would make nice big loops at full throttle, but as I said, was really anemic if you wanted to do a hammer head turn. The OS 40 may be stronger than the Evolution 46, but my minimums on powering a model is the largest engine they suggest, and I prefer going to the next size bigger.

The airplane is a good model for a first tail dragger. It's as rugged as any you will see. I've cartwheeled mine twice, breaking only the motor mount the first time, and the wing mount the second time with a minimum of damage (took about an hour to repair and have flight ready). I've bounced it around on landing like a basketball. I would recommend that you use nylon bolts to hold the landing gear on however, and make sure you check the glue joints on any arf in critical areas, especially in relation to the firewall, wing saddle, and the landing gear mounting block.

And above all remember, "Experience is a hard teacher. She always gives the test first, and the lesson some time later!"
