How is an Allison going to work? Are they going to put a Buchon style nose on it?

Whoa! Now thats a new thing! Im highly interested to see the progress on this one! I'm curious if they'll have custom designed cowlings to make the nose more authentic looking from WWII.




While we're on the topic of 109s....anyone see Fagen Fighters acquired a 109!?

I've been told this is a mock up with the only Bf/CASA parts being the landing gear...

I'm curious. What's the advantage to using an Allison instead of a Merlin?

It's going in with the exhaust configured to look like an inverted engine. Seems like this was done with an FW-190 not too long ago. This Hispano came from Connie Edwards long ago in a trade for a Barron.

I have seen photos of the custom exhaust used to make an Allison installation in the Fw 190D look like a Jumo 213 installation. I wonder if there is enough room under the Bf 109 cowling for that to work as well especially without an annular radiator mounted on the front.

Would really like to see a C.4k restored to original with Spanish markings.

They're doing it as a G-10 (they've got wooden formers for the bulges tacked in place)... that would give a little more room under the cowling for the drop-down exhausts. I can say from looking at the Allison installation on the MAM's Dora that externally, that one looks very good. There may be some weight/balance things to sort out on a 109 though- what's the length of an Allison compared to a DB, anyone know? And which one weighs more?

Lynn

Allison can be dead on for length at 85 inches (and there are long and short nose ones) and 300lbs lighter, which leaves room for exhaust mods etc.
For a low altitude exhibition type airplane, it's probably a much better fit than the Merlin was. Not so much if you want to shoot at things at 10000 metres.

The DB 601/605, Merlins, and Allisons all rotate the same direction(excluding P-38 variant). Right handed as viewed from the cockpit.

IIRC the Bf-109F(and later variants) had the vertical stab designed to compensate for a RH rotation.

Were the Hispano built airframes designed with a LH vertical stab for use with the Hispano-Suiza 12Z left hand rotation? I believe the first 25 or so airframes where German built and sent as kits, so one would presume they had RH verical stabs.

Airworthy? One day. I mean heck... we'll soon have a -5 Corsair flying in Honduras markings. If your looking for just a static airframe there are already a few...

AFAIK Hispano Aviacion (HA) received 25 fuselages in 1942/1943 without vertical and horizontal stabilizers. They also received the correct necessary blueprints. When they used the LH rotating Hispano-Suiza 12 Z-89 and 12 Z-17 engines, the vertical stab was designed appropriately. Around 90 built. When they built the "Buchons", the new built ones got the same vertical stabilizers as the original German DB-engined versions. They knew what they were doing. However when the ~ 90 HS-engined ones were changed to RR´s, the "wrong" fins were not changed, Spanish Air Force left them as they were built. So there were some "Buchon"-conversions, that had the wrong fin for Merlins. One of them was the first D-FMBB of Messerschmitt Stiftung, sn. 195. In 1983 this airframe was a 100 % loss due to a takeoff accident. The actual D-FMBB is a different airframe, sn. 156.
