You too, Su-31?

Careful checking on the main wing of Sukhoi Su-31 40 produced by Kyosho proved negligible discrepancy with twisting down to edge on both side though the rate of distortion differs promptly, of course this twisted phenomena should be corrected into zero thrust at any rate before fabrication. Obtaining the main wing with ultimate accuracy that has nothing to do with any distortion is a key to a happy Radio Control Model Airplane Life that I hope in future from now, I'm sure to do that tomorrow.
Though I want to go out to the flying place of holidays, too cold weather condition these days prevents me from doing that.
