All great suggestions. Sign me up for a copy!:)

Texantomcat, Do you have a photo of the mounting flange? I’ve never seen anything like it. If it is off a Defiant, surely there has to be some way of bolting it to the Merlin exhaust port(s).

Great photos of the main landing gear disassembled. Interesting engineering solutions. Thanks again for sharing Matthias!:)

Oh dear! There are some sensitive little petals here!:(
I was trying to be light hearted and not overly technical in my description of the propeller rotation.

Anyway, back to the subject…

Reversing the direction of an Allison from R/H to L/H tractor basically involves disassembling the engine to swap the crankshaft end for end, swapping some drives end for end and repositioning a couple of idler gears in the accessory housing, repositioning the reduction gear oil jet and scavenge inlet and rewiring the distributor for the altered firing order.
Now, it would be nice to know, for my own technical curiosity, if these guys have fitted a L/H rotation Curtiss Electric propeller, or have come up with a different solution.

For the record, the vast majority of P-38’s had handed engines for aerodynamic reasons I believe.

This thread seems as good a place as any!

Does any one have drawings for the Husun Mk III Compass?

Here’s a video of the DH-4 flying in the US. A great machine! I can’t wait to see (and hear!:)) the DH-9 fly.

Thanks for the link ZRX61. As an engineer, I am trying to understand the failure mode and sequence of events, with the view of maybe preventing a recurrence. I really do not need to know about the resulting gore. I have been to the Reno Air Races twice in the past and particpated as pit crew.
My heart goes out to the families affected by this tragic accident.
