Sorry, brain fart in my last message. They're 6353A-18 blades reduced to -30s and reprofiled by San Antonio Propellers. I have the 61196-12 piston and have sourced a 52940 shaft extension tube. Should now just be a case of setting the stop rings to something appropriate for non-feathering and...

Using 6565A-18 (DC-3 needle blades) cut down and re-profiled to -30 to match the rotol diameter of the spitfire. Same conversion as the Allison powered Yak9/3.

The -505 I have has the faired knee cam. The -489 I am converting to has the standard cam track, but I can live with the faired knee. In reality, I am just installing the shaft extension assembly, removing the distributor valve and making the -505 non-feathering. This is going in a full-size...

Cheers Michael. The liner inspects OK. I am back converting a -505 to a non-feathering -489

Thanks both. Always amazes me the amount of knowledge on these forums. Cheers, Dave

Hi all, Was wondering if anyone can identify which dash of 23E50 a 61196-12 dome might have been used with? I have cross-referenced as many Ham Standard manuals as I can find but the 61196-12 doesn't show up in the lists. The domes are available in inventory through parts suppliers so they...

Thanks Greg. Any thoughts on the original topic? Is it fairly doable to convert the E to an F? I see there are some minor changes to the oil scavenging system around the reduction gear, but other than that I can't see any show-stoppers. That being said I also can't find any literature that...

Thanks for the info everyone. For those who are interested you can follow my progress at - EAA Builders Log The basic design is from the original Clive de Cros plans which have been re-engineered to accept the Allison V1710. More details and some other builders at Spitfire Aircraft Workshop

Much appreciated thank you. I am building a full size Spitfire replica in Australia and looking at engine options. David

Hi all, wondering if we might have a couple of Allison engine specialists on the forum. I am looking at whether the V1710 'E' type engines can effectively be turned into an 'F' type engine by simply fitting the reduction gear from the F onto the E block. For those not familiar the E type was...

That’s fantastic thank you. Would you be able to share the drawing number you found this on? Thanks

Hi all, I am having difficulty finding any technical drawings of the fixed tailwheel leg on the spitfire. Specifically I am after material spec and wall thickness of the leg, if anybody knows? Cheers D
