Looks great

Is it necessary to place the Rx and GPS away from eachother? As they both listen are they not quite content next to each Other?

If so- you could put the video Tx on the other wing which would give you even more separation than on the tail. Plus will keep the weight on the wing tip roughly equal? I suppose it's less important with 5.8. And maybe it's easier to wire in the tail?!

Looks good, nice clean methodical :)

How can you only be using a 4 channel rx ? How do you control AP and multi cam switch ?

Quite simple
Servo ch1 - outputs SPPM 1 to 7 plus RSSI on SPPM 11 and LQ on 12
Servo ch1 goes to the SPPM intput on the ET Vector
Servo ch2 - outputs TX ch10 for the camera switch
Servo ch3&4 - outputs TX ch9&10 for the P&T servos.

Exactly how i've done my Penguin and Bixler2 builds makes for a tidy lightweight build.

I really need to learn about this sppm stuff. Great build blog

Looking good :D like the idea of being able to switch to the tail cam mid flight!

Do people have problems when mounting all the components on the main body? I only ask because I see a lot of people putting the rx or vtx out on the wings. I put mine all on the main body and it seems to be performing really well.

1.3 video often causes interference with UHF control if the video Tx is powerful and close by. The further away you get the more of an issue it can be.

I believe it's less of an issue with 2.4 video. Its almost a non issue with 5.8 video.

Im running on 1200 video no issues :) i have the Dragonlink antenna in the tail and my vtx on the front pod

That's still a decent amount of physical separation. 40-60cm perhaps?

The quad guys find it much more tricky. Or putting both of them in the hatch of a plane 5-15cm away is asking for trouble.

Yeah i'd say the two are at least 60cm apart :) Im building a quad at the moment and hope i dont run into inteference problems (?)

I'm only using 5.8GHz video and 2.4 Frsky for control but I'm going to put my vtx out on the wing just in case I change to UHF in the future... regardless, the separation certainly won't do any harm in the meantime :)

Its definitely the best way to get distance between the two. I just wanted to avoid butchering the wings and having extra electronic to connect in the field when attaching the wings :)

Rangler are your tail reinforcement rods in place permanently? I haven't put mine on yet but trying to do it so I can still remove the tail for transportation.

rangler · February 18, 2015, 01:58:12 PM

Its permanently in place, i have a skoda fabia estate and trasport all my ariframes with the back seats down.
I wanted strength more than anything for this build.
