I'm not really sure it needs an article. It is just time consuming to make the nozzles I simply cut off the original nozzles and let in a 5 ply (1/8th ) former into the very rear of the fuselage and at the sides of the nozzles using Aeropoxy and glass cloth to keep this part of the fuse a stiff as possible. Small beech blocks are glued to this former to receive the screws which retain the nozzles . Each half of the tailpipe (I have retrofitted the BVM F4 pipe) is located by two socket screws mounted in beech blocks glued to the rear former, like the BVM F4. The nozzles are lined with sheet titanium on 1/8th ply standoffs. and the inside of the glass nozzle is coated with heatshield. I will soon find out if this is OK as I am just completing this mod to my F15 before flying it with aTJT 3000 and then a JetCat 160. My F15 was extensively re-engineered in the load bearing structures of the wings , stab. and fins to handle this amount of thrust and the JetCat 160 will be de-rated. Hope this helps but if considered useful I will do an article for RCJI as the F15 looks just so much better with this mod.
