Sure is! Thanks for giving me the idea to hunt it up. So much easier than using the aluminum screen.
I spent most of the morning getting the elevation function to work on the jet engines. I used the HL elevation unit, with some of the case cut off so that it would fit inside the turret ring. The slide is made from a couple of telescoping, rectangular shaped brass tube. The arm that rides on the cam is steel rod, with a brass skid plate soldered onto it.
Here's some pictures from different angles.
There is a piece of brass angle that ties the engines together, I attached the slide to it with an R/C car swivel fitting. It slides on the screw to compensate for the forward / reverse travel .
And a link to a short video of it in action...

After I got it all working correctly, I added the covers, ducted fans, and hoses. Of course, now there is too much weight for the elevation unit to move without the clutch slipping. Gonna have to think on this for a bit. It really moves pretty smooth, so I might just add some counter weight, or a couple of springs to carry some of the load.
Here's the interior layout that I think will work out. Still waiting for a Taigen V2 MFU board to be in stock. ALso, there will be 2 ESC's installed, one for each jet.

- inside
The motors for the fans arrived Friday, so I tried running them up. Not sure if this beast will be able to run much above half throttle. Those little fans really move a load of air. Might not need those spray nozzles, after all, Mick!
It was about this point that I fried the ESC for the fans. Thought it was heavy enough to run the two. Think again.

So, ordered a couple of them. Hopefully they'll be here this week.
Cut and installed the hoses for the sprays and took it outside to get some decent pictures.
The business end.
Also made up the access ladder.
Guess it's about time to start some painting!
