  1. Bluebird servos in my 40% Dalton 300SP 5 Star Review

    Posted by on 14th Jun 2016

    Today I had the maiden flight for my 40% Dalton 300SP. The bluebird servos performed flawlessly. When I was doing 2, 4, and 8 point rolls they held the plane right on the marks. Will let you know how they performed after a few more flights. Need to go through the plane to make sure nothing shook loose.
