Tips for all Hawk Customers:

we had update the Instructions Manual for hawk,

Please Glued 2 Fiberglass for cover the plywood mount for Strong more...

mm?/ i did?
no idea i did but then yes we will do more inverted flights

Anton ,
good to see a pic of the F-16, but the one I'm waiting for is the mirage 2000, any info???

regards
Florent

i will when the weather is a bit better
and completely finished also from the inside

HI Guys
I just made some changes to my new hawk wing.
I was not mad keen on mini servos for the ailerons so I modified the wing so that a plastic servo box would fit. I lined the edges of the hole with ply to allow the box to screw down and this has made for a far stiffer set up and I got to use a standrd size servo.
Also the Flaps. I made the servo attached to the hatch cover. One side I stiffened and the other was left standard and there isnt too much flex in either.
For cosmetics I painted the trailing edges in the same colour as the model so that you can not see any bare wood

Ali, gree on the mini servos, JR 9411 are more suited but are a tight fit, but they will fit.
Regards,
David Gladwin

Ali,
Are 3421's OK for the ailerons?
David

Any idea for slotted flaps?
what I can think of is using ROBART external hinge point method.
regards

Albert

Someone just forward this to me!! COOL but simple is better!

Yep, thought about it. Have not taken mine out of the box yet since I do not have all the parts for it. But I did order some control horns to do the same, I take it I will have to add some material to the leading edge of the flap, or not make it move much.

i am getting ready to install radio into my hawk,

guys how about a few pics of the inside of your plane?

thanks

Thanks for sharing your thought.
To do this, what is important is the location of flaps external hinge pivot point, my thought is it should be located directly under MAIN WING TE where the flap is joining to. because it will determine the droping travel of the flap LE. And for a aileron LE designed flap, this is even more caution not to cause slight spoiler effect when deploying down. Splotted flaps have slightly different LE design.
Again, this is just ONLY my thought...

Best Regards
Albert

yep here you go
exept for the reciever but you can see where its going to be
the purple thing is a lipo pack 4400 7,4 volts for the turbine
i decided to use this since i am putting 2 x 5 pack sanyo 3300 in the nose to get the cg ok
the kero and gas valves , hoses , airbottles are beneath the "floor"
if anyone is wondering why the Jetcat was mounted :upon request of the customer
it was not my firt choice , i dont have jetcats

@anton and ali

found another small glitch
i was testing the gear today and found some problems
when putting gear out sometime the gears would not come out without some help
first i thought i did the mounting a little wrong maybe to tight
but found out this little problem
the cilinders input was not alligned correctly it will touch the frame when putting gear out and then cousing some friction
i used a dremel to cut out a little of the frame now all works ok
maybe you schould all check this this will save you a few hours off puzzling like me
and tell the manufacturer to check if the input is aligned in the middle (it is just a matter of drilling correctly)
note: the pictures show the gear in out position so you will have this problem only when gear is coming out!
just check if you have this problem if not leave it
here are the pictures:

Guys I like what you are doing with the more scale like flap but I am a little worried. From experience the last thing the hawk needs is more flap movement. I have been in situations Early on where large flap movements caused a pitch down that could not be picked up by the stab (No matter how much movement) Now I am saying this as a technical idiot and I do not know if the scale type flaps will lessen the pitch down situation. If so great lets go full steam ahead. But if As I suspect they do not cancel it they will only make it worse. So be careful.
David,
Whats the Spec on those Jr Servos
Sandor. I did see the potential of a similar problem with my hawk but I adjusted the position the actual retract on the bearers so this nipple cleared the wood work. I slid mine as fas as it would go toward the wing tip. Also I notice by your picture that you have raised the retracts off the mounts with washers. What I did was I removed the moulded lip that is on the wing around the retract mount opening. This meant my retracts could sit square on the wood mounts and slide toward the wing tip thus clearing the nipple.
I hope that all make sense. If not I will take some pics later today. Cant do at the moment as camera is flat
Here are some epics of my install. All done apart from the UAT which will hopefully arrive today

Hi ali

i considered the wood but that is not a problem since you just swap the gears left with right and the wood is no problem
it was for me a real mechanical problem
secondly i put the spacers beneath the gear otherwise it will rest on the fiber and not on the wood
now the gear is ok and all works

here are some nice pictures i found
for more details

http://s96920072.onlinehome.us/AWA1/...45/walk166.htm

done!
now wait for the weather
anton: you can use the pictures if you like
they are in jpg
sorry guys if they are big
and for the smart guys
yes i know the instruments are analog and no computers inside
i asked the rubber pilot if he minded and stayed quiet[8D]

"No Step" on the instruments....now who'd have thought that *g*

i hope to come with some good hawk-pics too as soon as my friend gets it there....i really got to go over and have a look!

well what did you think of the front one?

"spins prohibited"

actualy these warnings are for the owner of this model the "no step" is for the entire model
i feel sorry allready to depart it
but i am planning to visit ali next week in england
and get a few new ones

Sandor Hi,.
Pics look great. I bet you can not wait to fly. I would still advise you remove the moulded lip around the retract mounts and let the retract units sit right onto the mount. I think this would spread the load a lot better than everything going through the washers.

Ali,

The JR servo is the 9411 in UK/US (9401 here in Asia/ Pacific). It is a 5Kg mini servo with metal gears and really is a mini 9411 I have used a lot of them in my jets such as the BobCats, Sabre and even in my Savex L39. with total success. It is a tight fit in the Hawk wing but it will go in. Metal gears remove the possibility of any bumping of the surface damaging the gear train.

I too would caution builders about the slotted flap mod. As I wrote earlier the pitch down problem was discovered on the original Hawk and was fixed by DELETING part of the slot on the outboard section of the flap. It might look more scale but COULD give you problems. Just a suggestion.
Regards, , David Gladwin.

WING SERVOS, here is what I found today, I went to the WRAM SHOW, as i was shopping around, i stopped at the Hitech - Multiplex booth. Multiplex has 4 new digital servos out, this one i looked at was for a thin wing application. "Slim Star FL # M6538"

spec are; digital, metal gears, 2 ball bearings, weight- .81, tourque - 50.4, holding power 84-oz/in, transit speed 60* .09, dim- l/w/h in, 2.10x0.40x0.43

at the show, the young man running the booth didnt know to much about this new digital servo, nor did he know the price.

i will do some searching and see what i can find out.

also B&B specialties has a nice choice of tanks for the fuel, i picked up a 32oz flat tank that i will mount/place under the back servo plate, which i will raise to accomidate this new tank.

the only thing i needed but did not find was pilots,

where is a good place to get 2 pilot busts for the hawk

thanks again
