2nd Sailplane: BigBird or OlyII?

[Mark_Alan]

I am a very enthusiastic newcomer to RC sailplanes. This summer I flew a Highlander foamie, occasionally getting flights as long as one hour. Unfortunately, many of my flights are still under five minutes, and I feel ready to go on to a more sophisticated plane.

I'm considering either the OlyII or 100" BigBird. I'm heard great things about both planes, but I'm wondering what the subtle differences are. On paper, the OlyII appears to have better wing loading, but the BigBird appears to have a more sophisticated airfoil and leading-edge sheeting out to the tips. Which plane would be more appropriate for a novice pilot?

Thanks for the great info on this board!

Instead of the Oly, consider also Blaine Rawdon's Mirage, recently short-kitted by Mark Miller at www.isthmusmodels.com . It's about as easy to build as the Oly, but it's a more sophisticated design and a far better performer, IMO, especially for light air. The Big Bird is better suited for windier conditions.

Agree whole heartedly with Mark Drella in his assessment of Oly and Bird. Additional thoughts on the Oly's wing should be given if you decide to go that route. Built stock from older plans, there is a good possibility of wing flutter during launches. I usually have to go softer on the winch with the Oly than with an older stock Spirit to keep the right panel from fluttering. D tubing the front section may help or using a bracing system such as found on the Saggitta wing may help. Good luck in your choice and happy flying.

My vote would be Big Bird from skybench, Ray is a heck of a good guy. Will help with any questions you have. The Big Bird is my second purchased glider. I have only been flying it for 2 weeks but on the second day out with Big Bird I was able to log my longest fleight ever (26 min.) The plane just seems to float around the feild tipping its wings at the slightest differance of Air.
Dont be afraid to let is circle down wind, ease the nose down and it will come back. Can you tell that I am in love with my Big Bird:D

BIG BIRD

Have been slope flyer for the past two years. Getting back to my roots, sorta. Haven't build anything this big. Sould be interesting.
