RE: Seagull 40 size Spacewalker ARF !
Good plane for the money.
Excellent flight characteristics.
Tends to yaw HEAVILY at runup.
I had over 75 flights on mine when I lawn darted it.
I still miss it.
No problems in the build and I found nothing wrong with the instructions, but a few things ( like the engine mount ) required more work than indicated.
The supplied mount is a little small for a .46 engine.
This plane needs at least a .46 ( NON-LA ) type engine as it is not light.
It does float in for gentle landings.
