Default Nitro Models F-86 Sabre-140

I am interested in obtaining EDF setup information on 2008 Nitro Models F-86 Sabre-140 Radio Controlled Aircraft w/ 60" Wingspan (SABREJET) before I purchase it. I found this F-86 Sabrejet 140 size at Fly Model.
It looks like the retracts (Model FM05-101) on this plane are displayed at Fly Models Products.


What EDF, such as AirPower AP-1200 120mm Electric Ducted Fan Unit Combo - 10+ lb with Intake Ring Outside Diameter of 147mm, work with a F-86 Sabre-140?

Here is one option that I was just provided: DS75 HDT fan 110 mm EDF unit Nue 19 motor 1.5 8 to 10 Lipo, plus likely Castle 85HV ESC. This would cost approximately the same as Jet Joe 14lb turbine($1600), but not require AMA waiver.

I calculated the wing loading to be 36 oz/sq ft using specs at Nitro Models web site copied below.

Wing span: 60 in /1524mm
Wing Area : 887 sq in /57.2 sq dm
Flying weight : 13.8lbs /6300g
Fuselage Length : 67 in / 1700 mm
Engine Required : 2c 140 4c 180
Radio Required : 6 channels 9-10 servos
Top quality wood construction with fiberglass fuselage.
Detachable 2-piece main wing. with ailerons and flaps.
Detachable stabilizer, All hardware and Accessories included.
Optional pneumatic or electric retractable landing gear.

That model is designed as a prop driven model. I dont see any easy way to convert it to EDF unless you plan to completely rebuild the fuse.

Them saying it would work with a 12 pound turbin is just silly. No way.

I agree that it appears that this model is designed as a prop driven model. Thus, it would need to be converted to EDF, which may require completely rebuilding the fuselage areas for electronics.

I will likely go with glo power to save on $ and test it out before moving to $$$ e-power.

Larry, check out the Nitroplanes web site for a video of their Sabrejet with a turbine jet installed - amazing!

The plane in the video is not the same one they are selling

Different markings and finish scheme and landing gear. The nose intake has been enlaged and the tubine model has flaps in the wing and the ailerons are slightly different.

At a minimum they would have had to build a completely new fuse to install that turbine. Looks to me like they changed almost everything!

Thats a nicely done turbine Sabre but its not the one they are selling.

While I see some making difference, such as naming and skull with crossbones, it still looks to me like the same plane with turbine engine.

Maybe I am wrong here?

Have you ever looked closely at the insides of a turbine powered plane? You cant simply stick a turbine engine inside any old fuse structure and go for it. It just cant be done. Its almost the same for an EDF installation.

Look at the parts breakdown pictures. The inside of the fuse is typical balsa stringer, former and bulkhead type construction. Thats not at all how a tubine or edf fuse would be built. Its not stong enough fo a turbine and its way to cluttered up for an edf.

There is no way they used that stock fuse. As I said - at a minimum they would have built a completely new fuse. On top of that, they did major changes to the wing.

Its almost always easier to start from scratch when the changes are that major.

Im pretty sure its not the same plane except for maybe a few scraps of balsa here and there at the most.

See spec above that include "fiberglass fuselage," not typical balsa stringer, former and bulkhead type construction.

I recognize your point to best buy a model designed for ducted fan or turbine, rather than convert.
