I have the same Jet not build yet and i ll also use JetCat 120SE! I have done lot of research on the net and i havent found any article or built threat about the SM Plus Bae Hawk.
I will use PowerBoxed Royal 2x JR R900S receivers (i ll convert to 2.4 as soon i will feel confident).

Jeff here with Skymaster-USA

Our Demo hawk has a P-20 in it. we are also using the 2.4 JR system with the SmartFly EQ6. Its solid as a rock.

The jet fly's very well and the p-120 pushes it along great. Its a very stable flying jet.

Pay close attention to the Elvivator Servo setup. Make sure the servo's are not sitting on the pipe.

If you have any questions please fell free to ask.

Status: offline 		Hello Jeff,
thank you for your reply, i have 2-3 questions about hawk,
Since i have 9xii JR do you suggest me to use Spektrum 2.4 module and 9000 receiver (i m aware that royal can handle very well 2.4 systems)
I m thinking of upgrading the Aluminum Tube with carbon tube (is it good or not recommended?)
Any inside info about the known issue with the main Tank hole that is positioned at the top 1/3 of it?

thank you again for the support!

Status: offline 		Thanks for the note Jeff. Is there some kind of modification that needs to be done to keep the servos from hitting the pipe? If you use the recomended 8611 servos is this still an issue? What happens if they do contact the pipe?

I assume you dont want to fly your Jet without elevator

Jeff a piece of fire blanket under the Servos will help?

Status: offline 		I recomend mounting the evivator sero's on the top side of the servo trey, Not the bottom. This will give more clearance from the pipe. we used 8611 Servo's

Going with a carbon spar might save you a little weight but its no necessary to. If you use a carbon spar you shouldent have any radio problems from it.

I have been using the 2.4 system in my jets since the Spektrum DX7 came out. I have had 0 problems with it. We use the Spektrum 2.4 setup in all of our demo jets here at Skymaster-USA and we have never had any problems with the systems. We are using the new AR9000 receivers and the Smartfly EQ6 system.

I hope this helps...

Status: offline 		Hi guys:

This is the modification I did to my Hawk to solve the problem of the rubbing of the elevator horn against the aft fuselaje hatch and to solve the closeness to the pipe issue.

First I turned arround the elevator horn and trimmed the top and made new holes so tha the hole was almost vertical to the the pivot point of the elevator. This way you solve the rubbing problem and since the holes are closer to the pivot point the throw of the elevator horns are equal for up and down elevator. The reduction of the leverage from the pushrod, beacuse the hole is now closer to the pivot poin should not be a problem with strong servos (I'm playing it safe using two 8711, I know its probably overkill but I have peace of mind)

Then I eliminated the servo tray and made a new one and installed the servos facing each other flat on their sides. This way the servo tray protects the servos from the pipe and the geometry is better. The factory setup binds at extreme throws of the elevator since the axis of rotation of the clevis in the elevator horn and at the servo arm are 90ยบ to each other. This way they are both paralel and there is no binding.

I must say that I copied this idea from ACRORED that is our builder master at our local field, from another Hawk he built.

The photos below should solve any doubts if the explanation above is not clear enough.

Regards
Eduardo

Status: offline 		Jeff - Is the elevator servo tray supposed to have the servo slots pre-cut from the factory? Mine was not, seems like it should have been.

Status: offline 		No, mine doesn't have slots for the servos. I am in the process of doing the mods as shown by Eduardo. The suggested geometry stinks, as the ball link attaches to the control horn 5/8th of an inch in front of the pivot line and flat doesnt work. The fuel system also sucks, the clunks enter the tanks from the top and will not allow fuel feed inverted. I am in the process of placing 2 Dubro 50 oz tanks in mine to replace the SM tanks.
