Just finished a Tornado V3. Retract mounts are sized for Spring Air units, others might work, but will take modifying to fit. I couldn't get Spring Airs, so went with Robert air up/spring down. Dropped in perfectly with no mods. I also went with Robart 3/8" struts and small wheels/brakes, but if you can get the Tornado trailing link struts, would be much easier and fit better. I like the way the Tornado flies, but a one piece airplane is a little unwieldy, but still managable.

Good luck with your Tornado
