Z is on the gear with wheel pants. The mounting was pretty straight forward, but I think I will pull them back off and shim with thin plywood to take up the gaps behind the fiberglass giving the wood screws the ability to clamp the pants and not deform the fiberglass. It is also critical that the angle of the wire gear be bent to center the wheels in the pants. Mine are too far forward right now by about 1/2 inch and they rub on the front of the pants when the airplane sits on the bench.

I ordered a 1/2 3D printed Pratt & Whitney Wasp Jr. from Damon at Atwood Aviation. The diameter we agreed on was 9.6". He can print whatever a person wants. The plan is to install this on the front of a baffle in the cowl and then just expose the cylinder head for the Saito. The surprising thing is when you block all the open area of a cowling like this and duct the air right past the cylinder only, your cooling of the engine actually improves! Crazy thing. I will be using a thermocouple temp probe with telemetry on the head so we will have actual readings. The goal is continuous operation below 300 deg. F if possible. Leo
