I made a new thread here so the other gun guy can enjoy him self too: http://www.rcuniverse.com/forum/rc-j...l#post12300603

Now back to building

Aviation shows that you glue the wood with the elevon servos direct to the fuse..
I added 2mm G10 on one side for extra strenth and hysol it in place.
I aligned it and now it helds in place with four M4 screws so its removable in case i want to service something.

Also the last frame at the rear that holds the elevator bearings got reinforced with G10 inside out. ..now we can pull some cobra G





sand and glued with hysol




here can been seen also the mounts that hold the elevator servos in place

The fins have no rudders .Simple and light !

DelGatoGrande

My Feedback: (23)

but my flight envelope does include 4-point and slow rolls so i am getting them rudders

rudders been cut out and robart hinges will be used.

The inner hinge suport wood is made from multiple layers of 2mm balsa and 80gr fibreglass cloth in between !
And its hysoled in place!

And you have seen them REALY UGLY rudder links sticking out from the fins side. Not in this one.
Steel torque " Γ "rod passing thru and under the elevon servos makes a perfect hidden link.

The space where the rod will turn the rudder and it will get fulled with hysol.
The sides got reinforced with G10 as can be seen

My Feedback: (23)

Remember the torque rod must be aligned PERFECTLY with the hinges pivot point so servo wont be fighting the setup. Simple jig make this a piece of cake.

Next with scrap balsa and sandpaper making the LE of the rudder.
tip: The corect radius in each point is half the thickness of the rudder on that point

..some putty and sand and putty and fine sanding will give perfect gap result!

ball bearing hysoled on the other end finishes the setup!

25kg of torque from a hitec 7955 delivered with no endpoint redused= full torque / full resolution / hidden setup

Beautiful finish with no UGLY external links!
Plus rudders are removable by pulling the hinges rod from the top of the fin

So its 2011 and my scale chutes from D4S have arrived .

DelGatoGrande

My Feedback: (23)

And with my HotSpot as TestBed i am doing trials in a quiet parking place
25 years ago playing with Estes rockets had learned me how to fold a chute and with the help of PowerBox,
control was made from a single channel triple switch : 0= In 1=deploy 2=release (just in case lol)
Fishing wire pulling the model from the wing tube ,long enough to be away from the engine.


TEST CHUTE VIDEO LINK ! >> http://www.petame.gr/forumv/showthre...2648#post82648

My Feedback: (23)

and since they where on the hotspot at the time...i demonstrated them at the National Greek Meeting 2011 in 111AFB

DelGatoGrande

My Feedback: (23)

And after the tests getting them back to the SU-37.... Should be easy installation inside that big rear cone !




NOT!

DelGatoGrande

My Feedback: (23)

It looks that Sukhoi designed the chute to be on top of the aircraft between the fins and not on the cone at the rear end

DelGatoGrande

My Feedback: (23)

At this point the fuselage is not thick at all and a simple door can not be made. Actually the chute folder is the thickness of the fuselage at this point
So a compartment that will elevate had to be made..like the real thing.

DelGatoGrande

My Feedback: (23)

After alot of test fit and geometry trials its ready.Made out of strong G10.
Single channel operation again with the help of PowerBox .
Controlled with a triple switch, 0=closed , 1=compartment elevation and chute deployment , 3= chute release (just in case)

In the photo the deployment cylinder can be seen .It gets triggered with a trigger air switch once the compartment has reached the upper point.
The servo that holds the chutes is glued in the fuselage.The chutes stress the main wing spar and not the servo.Easy reloading even if released

DelGatoGrande

My Feedback: (23)

the old link with some photos and drawings explaining a servo release can be used with out stressing the servo..
