Not yet I'm afraid. It's 2-3 weeks standard isn't it?

i think your mounts for the dragonlink need to have a swinging mechanism. Not everyone holds a transmitter at the same angle which means the bracket will not offer best position for the antenna for everyone. BUT any chance of one that works with DX7?

This has come into question a few times, but as stated, I don't think a slightly misaligned antenna will mess with the range too much. I doubt there are many that hit the outer limits of their dragonlink range. It also makes a cable length issue, it makes the mounts less universal due to differing radio design etc... Im still dead set that a swinging mechanism would create more problems than it solves. If you would like a custom design though im more than happy to cater for it.

The DX7, what sort of module does it have? similar to the hitec? (when viewed from the back, 5 pins horizontal on the lower left portion of the module hole), JR/Turnigy (when viewed from the back, 5 vertically aligned pins in the lower right section of the module hole) or Futaba (when viewed form the back, 5 Pins aligned horizontally across the middle top section of the module hole).

A picture would help .

What happened? You changed your attitude towards it over night.

I don't see the cable length issue, why isn't there an issue with the stock holder then? I have lots of length left over, so much that I worry about snagging it on something even when the DL is fully rotated.

I have always held the position that a swing arm isn't necessary due to the sheer signal strength of the dragon link system. But as I stated earlier, I'm happy to accommodate others designs. The other issue of course is the unit compatibility changes. Currently, all of my futaba adapters will fit all futaba radios, the same goes for JR. if I were to implement a swinging system the antenna risks impacting the radio at either the back, or the bar. unless I separate the unit and hang the DL case from the bar, which as stated earlier, is a mounting system supplied with the DL V2. Im not entirely sure the geometry of having the hinge attached to the module would work universally with all radios, perhaps further research on this is required. Additionally, The cost of a 2 part unit would increase as they would need to be printed separately, so material used and print time increases (probably to the sum of 5).

mmm interesting design....will it fly ? possibly, will it fly well ? errrm maybe not otherwise there would be plenty mode full size equivalent ? I think it will need rudders

Mind you Burt Rutan has kinda sniffed around that...

Tandem wing, into which I have done a heavy amount of research. Main drawback is production time (you need two wings instead of one), not so much a problem for me. front wing is in effect a canard with an airfoil profile (Clark-y in this case). Advantages include wide COG range & shorter wingspan. Disadvantages, the rear wing flies slightly in the front wings washout (hence why it is higher, I may yet raise it some more). Wing chord, 100mm, each wing spans 300mm, leading to a total of 1200mm. Maximum all up weight, 1000g (a wing loading if 25oz/sq ft). Predicted airframe weight thus far, 620g. Gear on top (camera, 6 3.6g servos (one for cam tilt, five for surfaces, I have since added a reasonable rudder), motor, prop, spinner, ESC, 1800mah 3s lipo, DL Rx & OSD, misc cables and connectors & 5.8Ghz VTx gear) 330g.

Total predicted weight, 950g. Not out of the realm of possibility!

dx7 doesnt have any module...it has a 3.5mm hack where trainer leads would be put? see here for image:

Alright, I thought saying you would look into it meant you would consider designing it.
I'll just wait for the 9XR to be released, then we can work on a solution for that specific radio since the stock DL solution won't work on it, and it will be a hugely popular radio.

Probably for the best iskess. I'm more than considering to design it. But if you want it for a specific radio like the new Turnigy one, then it'd be best to Taylor it round that, rather than trying to make something universal.

Rsands2901, I think you may have missed the point of the module adapter, it's main function is to hold the DL on the back of a radio while making the plug in connection super simple using the existing module slot on the radio. If you have a radio without a module, there is no way to fix my current design to your radio, and if you can only then plug in via the trainer port, the two main functions of this mount don't exist for your setup. In which case, I'm not entirely sure what your asking for. A picture would help .

Got a few hours to go on it yet. Planning for a Keda out runner mounted internally. 30a ESC under the rear wing fuse brace. Gotta do ailerons and elevators, servos going to slot into the wing with their output shaft lined up with the control surface. Direct drive as it were. All internal linkages. Tilt mechanism for the camera needs to go in (I plan to use the same as you have for the reaper, link me?). It'll have a similar rudder mechanism. Again, direct drive internal linkage. 8X4 folding prop with cone spinner. The cloverleaf is quite clever, to save weight but maintain strength, it's actually positioned facing down imbedded in the front wing brace, the VTx will go above, in a cooling vent. Built in landing skids. Nothing will be a bolt on extra protruding into the air flow. It will all be "designed in" .
