Mike, designed the original kit version and unless I am mistaken the overall aeodynamics of the kit vs the ARF are the same, but the ARF has some slight tweaks to make it more mass production friendly. You might find this little fact interesting.

Back when the Patriot was being developed, Mike had the opportunity to race Dave Ribbe who was flying developing the then new P-51 sport from Great planes. Both were using the same power setups and you would have thought that the Patriot would have been faster, but nope THe P-51 was faster by a fair margin. Mike thinks the main reason was the fact that the Airfoil % cross section is pretty high(thick) which gives great handling at slow speeds, but you sacrifice a fair amount of speed. This is just one of the main areas that the Jackal is so fast as the wing is rather thin and yet the airfoil(designed by George Hicks) is very fogiving in slow flight resulting in a very easy to land sport model.

You do have to fly the bird down to the ground , but there are no unusual tenencies on approach.


I hope this helps

Bill,

I'm thinking a Jett 90LX. Will it fit? If so, will the airframe handle the speed? Your thoughts please.

Guys,

Glad to see the interest in the Jackal. Let me try and give you some more details and possibly answer some of the questions that you have posted.

The model you see me flying in the video has an all up weight of 7lbs. 9 oz. and I will tell you that at this weight the Jackal feels very nimble and light on the controls. In fact as you you can see the model slows down very nicely for landing with the use of flaps.

The flap are not an absolute necessity for landing, but do enhance this aspect of the flight profile and we all know the landing is what separates the men from the boys... If you so choose you acan fix the flaps in the up position as we have included an internal wood flap stay that will allow you to install flaps at a later date if you so choose.

I understanfd that you think the model is overpriced...well let's look at some of the features when compared so some of our more recent Hangar 9 releases in similar size.

1) The model has fully sheeted airfoiled tail surfaces
2) The wing is fully sheeted over a foam core to allow the airfoil to be as thin as we required and still maintain the strength for high speed.
3) The entire top black stripe on the fuselage is painted all the way from the cowl and onto the fin & rudder - this was done to stop the small pointed edges from peeling.
4) The top hatch is very generous and made from acrylic plastic to give better acces to all the interior gear.
5) The spiiner included with the Jackal is a CNC machined aluminumn lightedned back plate Hangar 9 spinner that we have painted white to match the model. 30.00 valus alone
6) The model uses tricycle gear which again adds complexity and cost when compared to a tail dragger
7) The inlets are fibergalss and are removable to allow the wings to pocket in to the fuselage and then the inlets slide up nice and tight to wing to keep the gaps to minumum. You will notice the inlets are designed to allow the boundary layer or air on the surface of the fuselage to pass by the inlets. This works to reduce drag and yet keeps the model looking more jet like.

Not many of you may know this when you campare this model to the Patriot, but both airplanes were designed by Mike McConville, so let's just say we incorporated some of the things that Mike thought were needed to that design.



The Jackal uses the new Robart PRS (Progressive Retract System)retracts which I have been developing with Robart for the last 18 months. These retracts are available as mechanical actuation (Two JR RT-88 servos) or Pneumatic. The reason these are called PRS is that we hope to be able to include the mechanical units with a Hangar 9 airframe and then if the modeler chooses he could purchase the air cylinder upgrade kit and convert to Pneumatic operation. These units come set up to accept Robostruts that you only need to cut the strut to length and then just slip intp the trunion and secure the set screw.


These retracts should bew availabel to next week as we have them in stock in the warehouse and the Jackal is on track to release the first part of October.


HAN501 Mechanical retracts 89.99
HAN502 Pneumatic retracts 159.99 includes complete air install kit
HAN502A Cylinder upgrade kit 95.99


I hope this information is helpful and we look forward to seeing these out there in your hands soon going faaaaaaaaaaaaaaaaaaaaaaaaaaaaaast.

Just pre-orded my Jackal 50, that thing looks fast, the hobbie store said November here in Canada. Thinking about jett 50 could't find any info on the jett 56. have the jett 50 in my patriot now, best engine in my fleet.
