I have the 60 size 300 and must say it is built very well. Flys as good as it looks and everything was straight. I have mine powered with a Saito 1.20 and while I won't say it is "unlimited" vertical, it does very well. The other day I had a dead stick with the plane and had to cross a pond to get back to the runway. the air press diff. from the watter caused my plane to drop like a rock and it went in from about 20 feet up. cracked the cowl and a little dent in one wing and that was it. I figured it was a total loss but I flew it again that day!

Some of the hardware is kinda cheesy and the landing gear is a little light for the plane but after you rebend it so it looks like it should have in the first place and it is fine. Mine has 15 or so flights on it and so far I am a happy camper.

Full up weight is almost 10 lbs with the Saito.
