Very nice! looking Hawk. I would like to do the details on wing some day.

Has anyone made functional the two hatch/doors on the nose? Like most people do on the Skygate Hawk?

Enjoy your Hawk! It looks just great. I agree the Hawk is very easy to fly but on landing don't try to hold it off too long. Let it slow and settle with the nose wheel about 2" off the ground when the mains touch. You will have quite a bit of elevator in at that point, but don't get too high an angle of attack it will bite! It is very maneuverable with great rudder authority.

I did it like this. Then I dont have to take of the cocpkit glass between flights. Its a flexible wire that i can rewch from the inlet duct that servers as the lock mechanism.

Kenrico

yea just what i would like to do, only difference i would prob try to hinge it from the top with some gear door offset hinges.

Were you able to use the same piece you cut out as the door?
what would be the best tool to do this?

thanks!

I did some CAD last week and designed Vortex Generators and the pitot Tube for the Hawks nose. Did a swift print afterwards and they came out quite good I think. Of course they have to be painted or printed in black / white according to the position on the wing.

If anyone is interested in either of those parts, shoot me a PM.

Yes, the door came out ok. I used the dremel with the thinnest round convex thing, dont know what its called. Taped a blade of a hobby knife to the door to make the line strait. The corners can be made the same way with a coin if your hand is shaky. The line will be less than one millimeter and it looks ok.

Hi Guys, I have the opportunity to pick one of these kits up at a very low price but the only reason to buy is for using it on grass runway of local field as I already have other jets suitable for paved runways. For those of you that have already had this jet especially Dave, do you think that it would be suitable for a semi rough / bumpy runway. I need it to lift off at about 100 feet as otherwise it would end up bouncing. Landing is not an issue and I can make it as light as possible with ample power.

I would appreciate your input if you have had the plane and are already using it on grass field.

thanks, Behzad

Behzad I only had mine briefly and it lifted off quickly with a 120 in it. The landing gear is stout no issues on grass I would think.

Hi Kevin, thanks. Did you sell yours? Bill flies the ultra flash there and I fly the Electra and we are okay. But he has a140 in it so it is a little over powered.

Yes I did awhile back I have an avanti on the go now. I have a spare canopy and frame to get rid of if you are in the need they are new.

Its a good grass field model, flown mine a tonne off grass and that includes a very bumpy strip in Scotland. But 100' take off is 30m-with a head wind it will, but you are launching it! Keeping it light is good, don't really see how landing is not an issue with the ground surface, but take off is! Depends on the gear/legs you use, the earilest legs had no down stop and the main leg can hit the ground.

140 is perfect power for it.

DUCMOZ

Hi Dave, thank you. The reason I said Landing is not an issue is because the field is over 700 feet long and has stretches of smooth surface so once we slow down and touch down, the plane settles nicely and even with a couple of bumps, there will be no problem.

thank you again

OK, then your fine, you can do scale take offs then, it gets lighter and lighter on the run so will be gliding over the uneven ground by the time its run that far. Big thing with all Hawks is to not be pulling/climbing while the gear is going away, Mr G adds to much more work for the cylinders, that and the angled out gear doors its why some people have trouble getting their gear away, I always release the climb as I hit the gear switch, my gear has never failed to go completely.

This is my nose pitot tube. Actually not finished and sanded, but you get the picture I thought I do this one myself as it seems there is no manufacturer or shop where you can buy these yet.

Building a T45 guys. Has anyone glued the 'bunny ears' on but made them functional? In other words cut the fuse under the ears for ventilation. Not sure it's needed but I like things functional.

Any concerns??

Kenrico

I think most people cut the fuse, I made mines functional.

Hey guys,

Any chance anyone knows the thread "pitch" on the wingmount bolts? I know/(think) they are M4x60mm bolts but don't know the pitch. Lost them before I even got to use them :/
Also, I have several shorter M4 bolts leftover, how to know which one is for the canopy?

Thanks in advance!

Dave Wilshere

You need a hole under the scoops ideally.
Std M4 thread is 0.7mm from memory. Its a std M4 thread. M4 x 15 for canopy

Dave

Yeah 4mm x60 for the wings. The 4mm canopy bolt is pretty short, 16mm I think.
I have 90 flights on my Hawk now. One more day of flying and I have to send the Cheetah in for its 25 hr service. That went by quick!

I have had the "opportunity" to fly my Hawk in pretty stiff gusty breezes and moderate crosswinds recently, up to 20mph. I found it to be a bit of a handful in the flare, in ground effect, with full flaps. It moves around a lot from the winds and it is pretty sensitive to pitch inputs... So a little more difficult to set it down at the perfect landing attitude. After getting the dreaded hops going on one landing I figured I was done for the day. I swear the last hop the Hawk wasn't even moving forward anymore. And I thought I had landings down to perfection after 70 good ones. LOL. (no damage besides a tail scrape) But i wanted to fly so I tried using takeoff flaps for landing at Dantley's suggestion and liked that better. The combination of less susceptibility to being blown about and a little more positive control feel for catching and correcting those bobbles in the flare was nice. Plus it seemed to stick to the concrete a little better on touchdown. I guess it would be fun to try a gyro in it and let the gyro make those last second corrections for me...
I also had an issue a month ago when my turbine flamed out on another windy day (no explanation for that, rogue air bubble). Due to being low and slow abeam the field I executed a 360 turn to final and came up couple hundred feet short. I opted to belly land gear up in rough grass with takeoff flaps. From the pilots position at that field I could not see the touchdown but it must have been OK because there was little damage. Fuselage strakes and one nose gear door broke off. a couple of cracks in the fuselage skin. Anyway easily repaired. My advice is don't overdo the glue on those fuselage strakes. I had blobs of Hysol on the tabs inside the fuselage and that did make a mess coming out. So as I said before 90 flights on the Hawk now and it looks a s good and flies as well as the day it rolled out of my shop. This is one tough airplane too, hate to say how I know. It has been a great introduction to turbine powered jets for me.

Husafreak,

Thanks for the story about your experiences. Ours is (slowly!) getting ready for flight and we've put so much work into it (too many "scale" features ) I've been getting nervous about the maiden. Glad to hear that its forgiving *and* tough...

Husa, where are you at for CG. I moved mine back over the winter based on some suggestions here but, haven't test flown yet. Getting a little concerned that maybe I moved it back to far.

My CG is 197-198mm. It is a good compromise for aerobatics, the nose doesn't drop in turns and I don't need ridiculous amounts of down elevator when inverted or rolling. But in the landing flare with full flaps it feels more tail heavy/sensitive. It is very honest but the nose will just keep coming up higher and higher if you command it to, then you get into trouble. As long as you hold your landing attitude (the nose tire a 2-3" higher than the mains at touchdown) and let it settle it lands great. It has a lot of drag and slows down quick after I chop the throttle so spot landings are a breeze. I am not using crow. It is a sweet flyer but mine won't stand for hard landings at high AOA. Mine will drop a wing or start bouncing if I do that.

Thanks, I flew it last year at 190mm but, have moved it to 200mm so, should be in line with what you have. It always felt nose heavy at 190mm, flew well but, required quite a bit of down elev for inverted and I would max out elev in the landing flare. Never had any tendency to tip stall or snap at 190mm though, maybe that's why it's the carf recomended cg?
