    Default model 3 converted to model 4 speedster

    I recently installed model 4 speedster wings on my model 3. I have already changed the cowling for the more sloped windsheild plus i installed the thicker windsheild 00.90. Still have the original virtical stab and rudder. next winters project. Still using the original mixer. the plane flys alot better now. landings are much more predictable. climb out is not that bad with 2 people running a 912 ul. Would it be worth it to replace the mixer?? adverse yaw is not that bad. cruising about 115 mph with ivo inflight prop. love the plane now. here are some pictures

    foxkit3,
    I can't comment on the mods, as I am still dreaming of building my own Model 7SS. However, can I ask what inspired the paint scheme? It's nice and clean...I like the mulitiple colors and the layout differs from what I've seen before.

    Are you using the Model III, flat bottom, flapperons, yet? (It looks like it.) If the plane flies good as is, I wouldn't change the mixer system.

    To update to the Model IV system would require lots of additional work, welding and fabric removal/repair. That would be a project for recovering time. (If ever.)

    Thanks for the positive remarks. Was not sure if I was going to get beat up or not for making changes to the plane. It was alot of fun I really enjoyed building and covering the wings.
