Since the weather is below freezing in the U.K. and has been for more than a week I canít get the shop warm enough to safely spray the UF Evo trays. I bought this Rebel Hott end of last year with the idea that there were dozens of JetCat P-60ís tucked away in boxes not used, as there are not many suitable airframes. The Hot is perfect and fits a need for me as a grab and go turbine, plus should be popular once itís promoted properly.
Iím going to use MacGregor 2810 servos throughout and either a Powerbox V3 Sensor Switch and 9ch Core Rx or a Pioneer. Either choice with the excellent ISat Gyro.
Since the P-60 is a little heavier than some of the choices Iím looking at the airframe to see where I can save a few grams.
Set up is the stock CARF tank/pipe and JP gear.

I'm going Pioneer with iSat and 26D receivers on my CORE, and probably MKS servos and a Swiwin 60b

I would very interested to see how you set up the equipment. It is the one area the Rebel design is lacking.

After modifying the tank in mine I used the orig front tank mount as the rear mount for my radio tray and then added two blocks to secure the front of the radio tray.

A few detail shots



Rex12 driving a Cortex Pro batteries are mounted up high above tank on plywood plates and secured with velcro 2S2000 lipo for radio a second 2S2000 powers the gear controller and turbine through a ďYĒ harness I made.

I've finished the last details of my Rebel Hot restoration. I've moved the turbine back quite a bit. I cut about 1-1/2" off the HAB G10 mounts and ran them all the way back in the compartment. As a result I trimmed about 4" off the tail pipe. I cut the pipe to match the shape of the tail, like the CARF pipe is done. That looks cool. The HAB pipe is 0.006" stainless-steel and cuts easy with lexan scissors. With a 1/4 tank and full air trap I at the center part of the spar for CG. My CG machine is set for the back of the spar. Weight w/ the 1/4-tank is a respectable 5.7kg.

I would change the line from the bubble trap to ball valve. Add a length and make a loop, it’s likely to leak pulling the tube across the festo fittings like that.

Looking at the Rebel and wanting to keep things as light as possible with the heavier turbine choice-plus I really want to paint the inside, I weighed the fuse shell at 1289g. From here I cleaned off any excess resin, sanded the wood work and gave it a coat of thinned Zap 40 finishing resin. I also opened some of the infill sections. Masked ready to paint, Iíve never actually weighted the paint/resin process.

Looking at the wing I decided to true up the wheel openings and lightly paint inside, I also wanted to bring any cables out of the LE opening, so I made a slot in the foam spar for the Aileron servo lead.

Dave,
Why the desire to paint?
Is it just cosmetic or for any sealing issues?
Curious how many ounces it adds ...

Just the large openings, I think it looks better. The grey I use hides any fuel staining, my Instruction manual Classic Flash will be 15 years old this July and it’s looks ‘old’ and dirty inside, my CARF Hawk is 11 years old and where I painted it grey inside...it pretty much looks as it did when I built it!
I tend to keep my models and they last, so it’s a step I like to do. Originally I used just grey primer as it covers really well, the last 5-6 years I have used a textured paint and experimented with coverage. Just spraying the texture on the white glass needs a couple of layers to stop the white showing through ( it’s basically clear with granules in!) but I found spraying a very light coat of grey primer, mainly in the corners and edges and before that has dried spray the texture over it you can put a very light coat on.

I don’t expect much weight, I hope it’s not as much as an ounce!

I see models like that 🙂 when the wood work isnít treated with resin I always say Ah you donít expect it to last more than a couple of seasons...

Painted the UF trays and fuselage. Will see what the weight is after it dries.

So paint is dry, itís added 26g ( less than an ounce) satin black in the tailpipe, grey in the turbine area and texture the front. Difficult to photo but you can see how thin the coat is. To the eye the coverage is pretty good

Nice work.
I've vowed to never use black inside a fuselage again. It makes it too hard to see inside.

It’s grey 🙂
To the eye it’s not too dark, plus I only had some of the shop lights on when I took the photos

Picked at some more jobs this week. Made up 3 long leads from Powerbox wire and male ends. Ran those down the fuselage and covered in alloy tape as my std for the last 20 years. That allowed the pipe to go in. Mounted the rudder servo and nose retract unit so now I can decide on an equipment layout once the wings are finished to allow a rough balance with the P-60.

Dave,
Are those MPI fittings on the servo and horn in the last picture?
How do,you keep the threaded rod from moving/backing off?
Threadlock liquid or add a jam nut?

Equipment supply CARF. Once the length is set I wick a small amount of Thin ZAP 08. To fill the thread clearance and lock them. You can still unscrew the fittings.

Decided to get wings pretty much finished so I can plan the fuselage layout when I get back on the Rebel. Going to finish the UF Evo completely before going back to the Rebel.
Paper towel is to soak up drips from the bike chain lube I sprayed into the oleo knuckle joints (I forgot to do it before installing the gear!
