Title: Jet Hellcat
Post by: Acree on May 21, 2015, 07:19:43 AM
Just wanted to give you guys a heads up on what I am working on.  Since I have a very limited stash (and even more limited stash-space), I usually decide my next build based on what partial aircraft is sitting forlornly in the stash needing to be kitbashed.  In this case, I had a 1/72 Hasegawa F6F-5 which had contributed it's engine and cowling to my SPU-1 Stingray and it's wings to my recent SK-1 Malt.  It was such a nice fuselage just sitting there... So I decided to replace the original engine with a much-smaller R-2600 from a B-25, supplemented by a jet in the tail.  The intake for the jet is directly under the R-2600 engine cowling, just ahead of the wing.  Having transplanted the wings to the SK-1, I looked in the stash for some wings that are not already dedicated to a future project... about the only things I had available were the upper wing from a Gladiator (definitely out!) and the wings from a Kingfisher.  I decided on the Kingfisher wings, which had two problems: 1. No landing gear.  I solved this problem using a dremel to cut out wheel wells and I'll make doors out of sheet styrene to cover the F6F gear.  2. The Kingfisher wings are too short for this Hellcat fuselage - I hope to address that somehow with high-lift devices and backstory. 

I have already installed the jet exhaust, which looks really good, I think.  I have also begun to craft the intake trunking and modified the B-25 cowling to keep the exhaust out of the jet intake.  The back story will involve the jet Hellcat being a backup to the Ryan FR-1.  If I had thought of it in time, I would have saved this for the WWIII GB, but I think I am too far along for that.  Even so, I may put it on hold to try to get another (different) entry into the Extended Service Life GB, if I can gather parts in time AND there is an extension.   

I will post WIP photos later tonight or tomorrow. Comments and suggestions welcome!

A couple of WIP photos to give you an idea what I'm talking about:

This build is more involved than it first appears.  Good job :)
Fireballs were retired in 1947 due to excess corrosion.  Jet Hellcat was needed.

Nice project and good start, go on! :)

I was expecting a pure jet Hellcat, something more like a Ta-183 "Hückebein" at the front with the tail as you've done it.

Yes, I probably should have said "Mixed-Power Hellcat."  I never really considered a pure jet. But it would have been a real challenge considering the size of the Hellcat's nose - it was really HUGE - about the same as a Thunderbolt! 

I think the Navy had good, logical reasons for going with mixed power before going pure jet (fuel consumption and unreliability of early jets being top of the list).

I think the slow spool up time of the early jets was also a key issue - especially for failed traps etc.

Absolutely!  I remember even in the 80s the (50s technology) T-37 had THIRTEEN SECONDS spool-up time.  I would have hated to try to land something like that on a carrier!

I couldn't agree more!

Looks like you found a gap that needs filling, Chuck!

You're off to a wizard start, too!

Well, the more I worked on the Jet Hellcat, the less Hellcat it became!  So, to see the end result, see my new thread: Bellanca FE-1! See here: http://beyondthesprues.com/Forum/index.php?topic=5654.0 (http://beyondthesprues.com/Forum/index.php?topic=5654.0)
