Alright alright alright! Florida Jets has come and gone and the beautiful Skymaster Large hawk took flight! In my initial observations, the aircraft flew very stable in what everyone knows are pretty harsh conditions at FJ with 20mph crosswinds with gusts. I have not installed the gyro yet and even though it does not need it, it will make those crosswind landins smoother!

The aircraft tracks like a pattern plane and maintains momentum when engine power is reduced. This is helpful in case of engine failure. Helps carry the plane and maintain speed while you select an emergency landing location and procedure. I had 4 flights at the show and every flight after fine tuning, the flights were even better.

Overall, I found the P200 to fly the aircraft with authority, flying at approximately at half throttle after established in the down wind. At full throttle, the bird really moves at a speed that is too fast for scale looking performance but the aircraft is solid and able to handle the power without a problem!

The expos and throws recommended by Anton are spot on. The CG is a little nose heavy for my liking and will continue to work on that after I install the gyro. With the P200, I was getting 10 minute flights and only using 1/2 the fuel tank. I use a lot of throttle management but a nice 10 minute flight with reserves is no problem! I did not use the smoke this weekend but will be used at Nall for sure!

The aircraft has a great presence in the air! The details are easily seen during low passes and even at higher speeds. It drew a lot of attention and the positive comments about the airframe were coming all day long.

I am looking forward to some tweaking and flying along with Craig South at Joe Nall!

Keep an eye out for the build and review of the New large Skymaster F-18C/D model to come soon!

Great Job on an amazing aircraft Anton!

Amazing Hawk, very good construction, very stable.
Thank you very much for all your help and advice.

Hello all, I finally got time to put in some flights on the Hawk and needless to say she's flying great! Luckily the weather cleared Saturday at our field here in Atlanta and I got 3 flights in on her. I was able to do some fine tuning after each flight and she kept getting better and better! My overall take on the airframe is its AWESOME!!! The Hawk is very stable in all speed ranges and at any attitude. You can get real comfortable with it in just a few flights.

I got a chance to fly her with the Powerbox Igyro for the first time and it performed perfectly. The Hawk is very stable and doesn't need the gyro but it will come in handy on windy days.

I am running the new PBS TJ23 turbine in the Hawk and its running great. The engine is super simple to install and makes great power. It pushes the Hawk around with ease and has a very quick acceleration time.

The Hawk tracks very very well, and holds a lot of momentum, which makes loops, split S's and all your scale aerobatics very smooth and effortless. I flew around most of the time at around half throttle and she was very happy there.

Im using the control throws provided by Anton and they are right on the mark. Ive got the CG a little nose heavy at the moment but it flys great with plenty of elevator authority. I will start moving the cg back on the next round of flights.

I had my timer set at 6 min and I was landing with more than a third of a tank left. With the tank almost directly over the CG I saw no trim changes as the fuel burns off.

Once again Anton has done a great job with the Hawk and I couldn't be more pleased. Danny and I will have ours at Joe Nall in just a few weeks, and we look forward to getting some good flying in. Make sure you come check um out!

Good to hear, Craig! Mine is getting closer and closer. Won't be too much longer!

We had some questions about ideas when it comes to installing the cockpit. In my plane, I made the instrument panel fixed and the two separate tubs removable separately. For the front, I made a permanent frame within the fuselage. I slide the cockpit in at an angle and set it in the rails, then I push it forward to its position. The rear cockpit sits on a fixed cross brace I installed onto the fuselage. This brace (See pictures) holds the front and the back of the tub itself rests on another rear piece I installed into the fuselage. The tub itself has been reinforced for more rigidity. See the pictures. Last picture of the inside and the frame does not yet have the middle cross mount. This was added a little later. Hope this helps you guys with the questions!

Thanks!

Danny and Craig ... I saw the reinforcement for the stab mounting location but did you also reinforce the area where the stab servos are mounted?

Thanks! Jamie

No, there is plenty of wood underneath.

OK ... thanks, man!

Getting more flights on yours? Any words of wisdom learned on cg, throws, etc?

Flies great. Make sure you build as light as possible. Factory CG seems a little nose heavy. Will be moving the CG back and today I am installing the AXIS gyro. Tomorrow I will fly it again and take some video.

Hello Craig

are you using a pneumatic fail-safe with your Power Box configuration?

Hi Craig

do you mind me asking what % you had your gyro surfaces set at?

thanks

I decided not to use a fail safe for a couple of reasons. First the gear is held up by air pressure and is pretty heavy which will allow it to free fall down. The second is the gear is designed with a new locking cylinder that locks the gear in the down position. In the event of a pressure loss the gear would drop out and all it would take is a little cross control input to lock um in place.

Without looking I believe my settings are around 55% on the elevator and ailerons. About 50% on the rudder. I also have the GPS installed, and the default gain reduction is working good.

Did you do servo actuated doors? If so, I'd be concerned that the weight of the gear battling the strength of the servo would stop the gear from deploying & send the amperage up high. On my Skygate/Carf L-39 with a Powerbox Royal, I setup telemetry to signal the pneumatic pressure back to my Futaba 18MZ, then set an alarm on the TX to warn me (verbally & vibration) if my pressure fell to =<50psi. Then if I feel the vibration, I'll drop the gear manually via the TX which will sequence the doors also. Works great, & is the best thing I could come up with until Powerbox integrates a pneumatic pressure sensor with a failsafe into their units.

HAS this Thread gone DEAD.. is there another BAE HAWK 1/3.65 thread ?
seems that no one followed up after the Florida Jets of last year on this thread...
so seems to me that there could have been alot more that could have been shared.....
I know for me I would like to know more about every ones planes..
and what kind of time did they have at Florida Jets.... ????
