Photos of tractor pusher pod

Here are some pics

The template is really good for the essential part: the lower portion where you
fix it to the Xeno - the upper part is up to you, depending on prop size etc.

I just tried it, and it works, you might go for slightly smaller angle up, but
it worked ok at that power level

for mounting the motor I just glued on two EPP pieces, and put a plywood
piece in front.

Most work is to get the curvature right at the bottom, for stability you need
to glue on some wood, and file it to the right curvature. I put some rubber
pieces on for vibration damping

I think it's 3mm plywood, anyway that should be fine

most importanty I learned that it won't work to try to fix it like the MPX
power cowling, the thin plywood gave way after the first hard landing

Better to just have some plywood extending below, and press the pod
to the plane usiing a zip tie around the inner body, just make small holes on
both sides to get the zip tie through

good luck with yours!

cheers
Clemens

Hi guys,
in the next days i'll receive my xeno. I'm reading this thread to prepare me to build it in the best way. I have a question about how to move the linkages on top.
I don't understand how to calculate the right slope to dig the hole across the wing. Can anyone explain to me how to do this? Unfortunately I don't speak german so the instructions reported in link at post 527 are unuseful to me, but I wish do a thing like this.
Thanks

Hi, Welcome,

My Xeno servos are on the top of the wing. Use the servo cut-outs on the bottom of the wing as a guide to cut through the wing with a sharp razor. Once you have cut out the pieces, slide them to the "bottom" and re-glue them in place.

Hi Nioa,
thanks for your reply.
I don't want put the servos on top of the wing. I want put on top only the linkages as shown in post 527 but I don't understand how calculate the correct slope to dig the wings. Can you explain me how to do this?

I just ordered one of these from eBay and cant decide if I want to make this a glider or more like an acrobatic plane with lots of power. Would adding 50 grams of weight make a big difference on how this plane would glide?

Angelus, I think that contributor just poked the linkage through the wing by estimation. I know you don't want the servo on the top of the wing, but consider also that the control arm can easily be moved to the top of the wing too. If the control arm is on the bottom of the wing, you can still damage the servo and the linkage in a bad landing. Moving the servo and the control arm to the top of the wing is the most protected position.

Thinking about picking up a Xeno. Does the kit come with a motor mount to attach an outrunner?

Sadly no. You will have to make your own. Many people use plywood and mounts from other planes.

Around here the motor set was sometimes sold quite cheap. ESC and motor with local (not Honkong) prices and a bit for the mechanics were not much cheaper than the set which works quite well.
At the moment the regular price here is 85 for the set and 50 only motor and ESC.

And a picture of what I used with my first XENO:

Looks great! I picked up a new xeno on ebay for $35 and I'm still in middle of building it. Is a folding prop "a must"? I got plenty of 7x6s APCs so if I would buy, lets say a 1600kv motor with 300 watts, I think that would work pretty well. I never used folding props and they seem to be expensive-ish.

I have the Multiplex motor set on mine, but I've got several other wings that I just use a regular prop without any problems, and I fly out in the desert on gravel and sand.

If I were to rebuild my Xeno or build a new one, I'd put the servos on the top rather than underneath where the control horns or servo arms can be damaged. I wrecked one servo with just a normal landing, on the sand. Other than that I really like mine.

The only reason for the folding prop is that this was intended to be a gliding/soaring plane and the folding prop is more aerodynamic while gliding.

AND it will survive better at landings. Gliding with a normal prop is not very funny.
They may be a bit more expensive, but they probably won't break. But you need to limit the blade travel for tail props so that it doesn't swing to the front or cross in the back.

The servos can stay where they are, but you can put the linkage to the top which is definitely a good idea.

The motor mount situation of the Xeno reminds me more of the wonky mounts on the TwinJet more so than the streamlined FunJet and Ultra!
