Hi Aronw , sorry for the delayed response to your email , I'm more than happy to share what I did on my two HH-3 Lindberg kit bash . The first three pic's are of the USAF HH-3 , from what I remember there was a slight discrepancy where revell's cockpit front halves join the lindberg fuselage . That is , the lindberg fuselage is a fraction wider than revell's front section . I taped both section together for a dry fit and decided to glue each front half to each fuselage half , so there was a slight gap when the two halves were glued together down the centre join ; not a big deal but something you will probably notice if you follow what I did . As far as the interior is concerned the seats came from a Italeri UH-34 Seahorse but I had to add some plastic strip to the bottom of each seat to raise it up to the right height . You really dont see much of the interior when everything is closed up but you can see the red seat backs from the outside so I put them in for that reason . the rest of the interior you can please yourself , I had some spare ammo box's and I just remembered I put in some stretcher/seats that came out of the revell kit [ I think ] I'll have check on that ? . So that brings me to the most challenging part of the build the rotor housing ; If you look closely at the first three pic's of the rotor housing , I think it was easier than what I attemped on the second USCG 3F build . I tried to use the whole rotor housing and exhaust section on the 3F but I just created more work when trying to join the lindberg engine housing piece , it didn't fit flush which requied a lot of sanding . The way I did it the first time by using just the rotor housing middle section only , was a much better idea . I guess I tried to be to clever on the second build and really made things a lot more difficult , "Oh well-live and learn". One thing that did work out well on the second build was the slight droop in the rotor blades . One other member of FSM forum pages did something similar about the same time I did mine using a similar technique . That pic is on a different disc , I'll find it and post it shortly , I was very pleased how it worked out . Revell's cockpit really does improve the front section and wasn't that difficult to join onto lindbergs fuselage , with the rotor housing just take your time like I did , I always cut well away from the line's I mark , It makes for a lot more filing and sanding , but I would rather do that than cut to much off . Illl go and have some dinner and think more about what else I did and I'll find the rotor hub and blade pic . I'll be back in about two hour's . Kind regard John .
