RE: Jetlegend T-45 Hawk
Ken, I just noticed that you have the rubber grommets on the servo, I would suggest removing them, you want that servo mounted ridged otherwise you can get undesired movement in the elevators.
As Bob has mentioned about the clearance I assume that you checked the clearance on the control rods to the servo case, from the angle of the photo it looks like they should clear. i.e. the full throw stop (new control rods will hit the frame) will be less than the arc of the servo arm to the case.

RE: Jetlegend T-45 Hawk
Let me answer some of your questions and add some additional photos.
- The servo arm is 0.75" L (center of screw to outer most mounting hole).
- Use of the rubber grommets are not an issue, the servo is solidly mounted on the frame.
- The linkages do not hit the servo case. The only interference in the setup is the base frame
that mounts to the wood bulkhead acts as a stop when the full throw is down elevator. And
when the throw is up elevator, the corners of the servo mount frame closest to the new mod
parts do prevent further travel, but it is already well past the necessary travel for flight.
- I did have to make an adjustment to the position of the shaft clamps that receive the elevators
relative to the angle of the modified parts from Rich/GJC. If you look at one of my photos you
can see that I aligned the black mounting clamps in-line with the servo mount frame. This is a
good reference to ensure you get the right setting for the throw needed for the elevator.
- I have yet to do the final tweaking of the travel in the transmitter, but shouldn't be a problem.
I have already test mounted the setup back in side the fuse and found the travel, done manually,
is sufficient. Now I just need to set the full throw electronically via the Tx.
- One other thing, I set the angle of the new parts so that they do not touch the linkages as they
travel the full path back and forth. I do anticipate the new parts to loosen and slip (rotate about
its axis) over time. I may add some loctite to help keep the screws in place.
Hope this helps...

RE: Jetlegend T-45 Hawk
Thanks guys! I'm looking forward to the test flight, I think... 
Super clean installs aren't my thing - not enough patience, but they do work. Here's what mine looks like. I have a 16 oz. additional tank that is made by the GJC for the 1/8 F-16's. I'm using a 5-cell pack with Fromeco regulator for the RX, a 6-cell NiCD for the ECU, and a 4-cell light pack. All are right up front and I still needed about 6 oz. of lead to balance.
Its an 8-channel FASST RX and mostly Futaba servos, so I didn't use a PowerExpander with this one. The speed brakes are operated off of the flap channel with a channel expander - go to full flaps, hit another switch, and the speed brakes come out. Put the flaps up and the speed brakes come in too.

Edgar,
The pilot is the 1/6 scale Blue Angles pilot figure, by Blue Box, I believe. In this plane, because of the equipment tray, the cockpit is very shallow, so its only his top half... [X(]
Of course, that did work out OK because my son had broken off one of his legs while playing with it a few years ago...

David,
There are small set screws in the mechanism you'll need to loosen up. Use the same Allen wrench to push the pins out. You will also need to remove one side of the bearing support brackets to get the red anodized control horn out. Hope this helps.

RE: Jetlegend T-45 Hawk
hi guys
my name is jean-pierre I'm in france
I have order a JL t45 to jeff sewel I'll recieve it in a few weeks!
Where can I found pieces to modify the elevator? Is it obligatory to fly with the plane?
thank you
JP

Hi JP,
This is the part that everyone's talking about. Ken's got a smart way to connect just one servo for the mechanism. I would never figure that out myself in a million years.
