Large Skymaster Hawk build
#651
That' scheme looks fantastic. That was going to be my second option. I went with the RSAF camo. I ordered mine with Dirk from kingtech; those guys over there provide great service!

Skymaster offers 1/4 pilots that are the perfect size. I had 2 in my Saudi Scheme Hawk. Warbirdpilots.com has 1/4 pilots as well, but I haven't seen them in the cockpit of the Hawk, so I can't say if they look appropriate. I have the new SM T-45 on order and I'll be using the SM 1/4 scale pilots.

I am getting ready to hinge my flaps and the slots are way off. They are a 1/2 inch too far aft. I can move the front of the hinge forward, although you end up having nothing to glue to forward of the block around the original opening. However, moving the hinge on the flap itself moves it really close to the leading edge of the flap. On top of that the slots are pretty sloppy width-wise. Not real happy with how they are set up.
Are you guys just glueing the aft hinge in at an angle? Does it affect the geometry doing this?

Get the front one to fit all the way down, flush with the notches of the hinge on the wing surface and by doing that it moves the hinge point back and the rear one should fit the same, just clean up the slots on the wing so they fit. The hawk and PC21 have the same setup and it works. Just keep the back of both front hinges the same distance from the rear of the wing. Have a look through the PC21 thread as well for confirmation of what I hope I described ok.
The Hinge covers are another story though, but with lots of patience the end result is worth it.

Looking at this photo they didn't line the hinge point up with the hinge line. Is this acceptable or should I move the hinges forward?

The photo attached is the picture taken from the Hawk manual. This is what the manual says. It also appears they moved the hinges forward. Not sure why the jigs haven't been fixed.

Check that slots for flap hinges line up. Pivot point must be
where leading and trailing edge meet. Cut slots if not happy.

That PC21 pic is correct. The hinge line is not the front of the flap. Keeping the rear of the front hinges the same distance from the rear of the wing (i.e. front of the flap) the hinge line geometry is correct on the pivot bolts, which all works out fine.

Ok guy's,... Let's talk wing fences... Who is useing them and your thoughts ?? The ones that came in the kit we're building now won't even go around the leading edge... My thoughts are that they sent the fences to the 1/5.5 kit accidently.. Any of you guys have this problem ? And back to my main question, are the needed for stability and tip stall ?? I have always been told that flying a Hawk without fences is like useing razor blades for toilet paper !! I had the the 1/5.5 kit, key word is HAD.. So I think there is truth to the myth... Please tell !!!
Thanks,

Peter Goldsmith showed me during an event last year how if you sight down the wing the Hawk has a bit of wash in built into it so if you set the ailerons just a tad higher than the flaps (flaps up, ailerons neutral) you end up with slight wash out which will help with the tip stall tendency. I'm building the 1/3.65 but I think the same would apply. Thought I would pass this along because I never would have seen or thought of this. JS

I have heard of this now that you mention it... A very slight full time crow in essence... How much are you planning to use ?? I would think the thickness of the aileron at the flap joint up wold be enough.. Thoughts ?

As I did write the turbine was move from standart position to the tail. To minimize ballast at the nose all servos (elevator, rudder) installed close to CG

There are hard mounting points in the wing. Look for small dimples or indentations on the bottom of the wing. They can viewed form either the gear mounting area or flap servo opening. I used 4-40 threaded inserts on the mounting points. My mounting points did not align up with the pylons so I re drilled the holes in the pylons.
As for transporting I made a tray the size of the fuselage and I'm using 3 " foam, leaving an opening for the ventral fins, then strapping the fuselage to that.
FYI I have not transported mine yet and the maiden will be in a couple weeks.
K.O.

The biggest that is on the market. Not a Skymaster or Comp arf.. Scott Marr flew his a First in Flight last year and it is BIG!!!
I have seen a video of a 1/3rd MK66 Hawk that is bigger but I don't think you can purchase it in any form kit or plans.
