blackbetty Posted December 14, 2017 Author Share Posted December 14, 2017 (edited) as seen here. now the fit is better. cut down trumpy flaps to get an idea of placement of these. the -7 (as the AU-1) had the exhaust located further down as the -5, so i will have to grind a recess (black marked) and fill the lower cutouts pretty flimsy at the moment, but i think i can make it work 07 by karl holubar, auf Flickr Edited December 14, 2017 by blackbetty BradG, Shawn M, Out2gtcha and 2 others 5 Link to comment Share on other sites More sharing options...

LSP_Paul Posted December 14, 2017 Share Posted December 14, 2017 Looks good so far Karl, it is going to be fun to get the ducting correct, I know you can do it. All the best, Paul Link to comment Share on other sites More sharing options...
blackbetty Posted December 14, 2017 Author Share Posted December 14, 2017 i will see how the ducting of the eyhaust is routed. i have pics of Bordellons plane that show some kind of square tubing around the exhaust pipes. good that its hard to see it i filled the cutouts with superglue and micropearls, then ground the new recesses i have a lot of more doubts about the cheek intakes. i only have one chance with the resin, if i mess up i´m screwed. i tried to vacform the cowl, but its too deep 08 by karl holubar, auf Flickr Out2gtcha, TorbenD, Shawn M and 2 others 5 Link to comment Share on other sites More sharing options...
LSP_Paul Posted December 14, 2017 Share Posted December 14, 2017 I had thought about making a 5N conversion but I was going to modify the kit cowl with Milliput or Apoxie Sculpt. Draw an outline of the side scoops on a piece of white plastic. When you have the shape you like cut it out, make a duplicate. Glue the new scoop patterns onto the kit cowl and build up with plastic and putty until you have faired in chin scoops. Create the intake cavities for the new sculpted scoops as the epoxy putty is drying with sculpting tools, toothpicks etc. Paul blackbetty and Harold 2 Link to comment Share on other sites More sharing options...
blackbetty Posted December 14, 2017 Author Share Posted December 14, 2017 (edited) i do want to use the resin cowl as it allread has the bulges on the sides and i only have to create the intakes. i have some good pics, we will see how that works out...

Tailspin Turtle Posted December 15, 2017 Share Posted December 15, 2017 what on earth is a "tri prism retro reflector" ? "For night-fighter gunnery training purposes the F4U-5N had three retro-reflector devices (trihedral prisms): one on the upper surfaces of each wing tip and a third located on the tail cone. The prisms were used in conjunction with a light projector and the gun camera of the pursuing aircraft." blackbetty, RLWP, Shawn M and 3 others 6 Link to comment Share on other sites More sharing options...

Googling for "tri prism retro reflector" brings up lots of stuff about devices that reflect light back in the direction it came from.

blackbetty Posted December 19, 2017 Author Share Posted December 19, 2017 (edited) worked on the cowling and the cheek intakes. located them first (not easy) and drilled holes that i made into slits 08a by karl holubar, auf Flickr then i formed the bumps with miliput. used water and various sharp and round objects to get it in the ballpark. after drying over night some sanding and grinding with the dremel took me near the final shape. first coat of a guidecoat here 09 by karl holubar, auf Flickr 10 by karl holubar, auf Flickr still have to work on the shape though Edited December 19, 2017 by blackbetty Harold, Dragon, alain11 and 6 others 9 Link to comment Share on other sites More sharing options...
