Mr67Stang -> Which F-86 is this? (10/9/2012 2:58 PM)

I just found this nitro ducted fan (old?) F-86 for sale. I am ready to jump on it. I think it may be new, never flown. He has the engine and pipe, I'm not sure if he has the fan and he has no servos for it. If you look in the picture he has Vietnam collectables in the back ground and did not advertize the plane as an F-86, just "radio control airplane". No specifications what so ever.

EDIT: I got some more pictures of it and the engine he has is a K&B 6.5 (.40) and he says the wing span is about 47 inches.

Dunno, new postage stamp by the USPS maybe?



TCHIEF -> RE: Which F-86 is this? (10/10/2012 2:11 AM)

Looks like house of balsa or the Pauls flying stuff f86



GSR -> RE: Which F-86 is this? (10/10/2012 2:41 AM)

JHH probably. HOB was basicly a flat bottom airfoil. S



Mr67Stang -> RE: Which F-86 is this? (10/10/2012 4:28 AM)

More pictures added. It has fixxed gear which will work for my less than perfect flying field.



jet time -> RE: Which F-86 is this? (10/10/2012 5:28 AM)

It's a Jet Hanger F86/Fury. The big cheater hole is a give away!
Great flying plane I might add....
Looks really well built and finished.

dbsonic -> RE: Which F-86 is this? (10/10/2012 5:45 AM)

Agree JHH F86/Fury. cheater hole and the way the hatch is done.



jetdriver -> RE: Which F-86 is this? (10/10/2012 6:38 AM)

It is a Jet Hangar Hobbies Fury ( navy version of the F-86)

here is a link to the turbine version sold by Global jet club. Should be the same size plane. maybe you can get some info here.
I have this plane that I would be willing to sell. new, 100% complete with unstarted P-60

Turbines are still out of reach for me so I will go with the nitro ducted fan. This guy is selling this one for $300 and I will just have to get a starter extention for this one.



jetdriver -> RE: Which F-86 is this? (10/10/2012 7:51 AM)

should be a good flying plane. LOTS of wing area. Good luck with it

It does look to be an older style Jet hangar Hobbies. They do fly very well.
If you do fly it as a Nitro ducted fan, on take off DO NOT TRY TO force her into the the air. You really need to do a scale take off. Right after she lifts, you need to hold altitude above the runway in ground effect until she gets her air speed built up. Then you can start a climb out. I use to have one many years ago and this is how I use to have to take off. Here is a pic of my old JHH F-86.

Also, here ifs a link for a video of my HPjets F-86 on a K-80. I still do the scale take offs. They just look so good.

The 6.5 is going to be very marginal getting it off of grass. Most of the JHH F-86s have the K&B 7.5 or OS .46s in them. The 6.5 is going to be very finnicky and probably require lots of nitro to get the RPMs. The most reliable and powerful setup was the last OS .46VXDF. The 7.5 RIRE with the machined carb was the best of the K&Bs.

I agree with Jeff that the OS was one of the better setups. Mine was set up with a Turbax one fan and a JETT Engineering Engine. This set up was just as strong if not stronger then the OS.


I Believe I had the .46 in mine. Here is a link to Jett Engineering.

Not sure if they are still making engines or not.

Mr67Stang -> RE: Which F-86 is this? (10/10/2012 2:07 PM)

Maybe he has the engine wrong. He just sent me a picture of the engine. It is a Rear Intake/Rear exhaust engine. Did they make a 6.5 in that configuration?



Jetpilot24 -> RE: Which F-86 is this? (10/10/2012 2:42 PM)

could be a Rossie engine

No, in this very blury pic you can make out the K/B on the side.



Art ARRO -> RE: Which F-86 is this? (10/10/2012 10:48 PM)

Mr67Stang,
The engine in the photo is a K&B 6.5 pylon racing engine-vintage unknown.  It does not have a carburetor only a venturi with a fuel cutoff feature by sqeezing off the fuel line.  Also, there is a pressure tap on the crankcase for feeding fuel to the engine.  It will run at or near peak RPM with no throttling ability.  An OS 46 VRDF Carb can be fitted but a backplate adapter must be fabricated from bar stock.  I had Clarence Lee perform this on a K&B 7.5 Marine engine and it worked well before  switching to a Fan Jett 50 engine which was far superior and more reliable than the K&Bs.  I don't believe Dub Jett is offering the Fan Jett 50 anymore.  I do recommend trying to buy an OS 46 VRDF or equivalent fan engine  and fitting it to the fan unit.  Jet Hangar Hobbies may have these in stock or look on ebay or the RCU engine listings.
Does the F-86 have a tuned pipe and header with the package?

Isn't that a little big for a .40 size ducted fan?



Airplanes400 -> RE: Which F-86 is this? (10/11/2012 2:09 AM)

Looks to me that the jet was built a very, very long time ago. All the epoxy has yellowed. I also confirm that it's a JHH model from the late 70's ~ early 80's.

With a 6.5 engine, the jet would take a long time to get up to speed on a paved runway. On grass, I doubt it will ever get airborne except for jumping in the air after hitting a clump of grass. Then there is the danger of it stalling because it has minimal airspeed. Don't try any steep climb-outs. Take-off's will be hairy and exciting ... to say the least.

If it does get in the air, with a 6.5 engine, I think it will be sluggish / under-powered.
Go with an OS .46 VRDF engine, or better yet, go electric.



jetdriver -> RE: Which F-86 is this? (10/11/2012 3:31 AM)

have a look http://www.jethangar.com/


http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXBY99&P=SM the 46VRDF has been discontinued for several years now.


I would call Larry at JHH and see what pipe he recommends. I would also put either a BVM or JMP remote needle on it. just my opinion



TestPilot-101 -> RE: Which F-86 is this? (10/11/2012 4:03 AM)

What you have there is an old Airforms F-86. The flat sheet stabs are what separates it from JHH' s F86.
I own one just like it

Here is a picture of the pipe and another were in, it looks to me to be a throttle arm on the carb. I can not verify if he has the header manifild or not. If he does not I have already found an OS .46 VX-DF new from TH for $315. I might be interested in electric if it could be done for the same price ($315).



Art ARRO -> RE: Which F-86 is this? (10/11/2012 10:30 AM)

Mr67Stang,
I see that you have a tuned pipe and header for this engine but it is still lacking a carburator. What you see as a throttle arm is the device used to pinch off the fuel line, working as a cutoff.  There is no rotating barrel as required for a carb.  Another carb may be fitted but the intake port on the backplate is rather small in diameter limiting the size of the carb.  A manifold is also necessary to connect the pipe to the engine. 
I'd go with the OS 46 VRDF but you may have to widen and redrill/tap the engine mounting pan to fit this engine to the fan unit.  The OS crankcase is wider and has a different bolt hole pattern compared to the K&B. 
The Turbax fan unit appears to be a very early vintage but that is really no problem. Be sure to balance the fan rotor before running the engine.
 I still recommend contacting Larry Wolfe, or his son Chris, at Jet Hangar Hobbies on advice for this setup.  Electric DF would be preferable but the cost of batteries may/will be greater than the OS 46.  There's also limited room in this jet for the batteries required to fly the model successfully.  Good luck with this project.

Mr67Stang -> RE: Which F-86 is this? (10/11/2012 10:57 AM)

So the engine is pretty much worthless. Time to reconsider if the buy is worth it or not.



Art ARRO -> RE: Which F-86 is this? (10/11/2012 1:13 PM)

The K&B 6.5 pylon engine is unsuitable for ducted fan use as it doesn't have a carb or means for throttling it.  It may be worth something to the speed guys over in the Extreme Speed segment of RCU.  That said, you can purchase a new or "like new" OS 46 VRDF or VX-DF for DF applications.  This engine should have a proper carb in order to throttle it for takeoffs and landings.  There are many "bargains" for glow-powered DF equipment and it may be worthwhile to search around for something suitable/affordable.
Also, I did not see a tailpipe in the photos of the F-86 and a tailpipe is recommended for best flight performance.  This could be made from rolled fibreglass sheet or purchased directly from Jet Hangar Hobbies (JHH)-see web link posted previously.
In any case, it would take some effort to get this F-86 flightworthy, but it depends on what your investment would be, both in time and $$$.
