Blocker great build, I just ordered a plan set and short kit from Solopropsll. Following your post I got a O.S 300 I plan on looking into the scale Windscreen and glass cowl. I built an AA Industries 1/4 scale Champ it’s powered with a os 120 gemeni two. Your using a os 160 twin hey great engine, like to know how it performs in your 1/3rd scale. I am planning on polyfibre glider fabric for covering and heavy silk on the control surfaces. I like your Aileron control set up. Are you going to use a pull pull on your rudder. I would sure like to hide the elevator control and use a pull pull system on it also. You got a great project! AJ
