On all my pusher prop wings, I think I've only broken a prop on landing once or twice. Here's my solution to powering the Xeno. It's a 3000KV 24g "blue wonder" with an 8x4 folder. The ESC is much bigger than it needs to be, but I needed weight ahead of the CG anyway. I use it on 3S, and while the performance isn't rocketship like, it keeps the plane in the air just fine. It's made so the wing still folds too. The black circle on the left wing is a lost model alarm. The wing is notched for prop clearance, and put a plastic plate across the back of the prop yoke to keep the blades from over folding(if a blade goes over center to far, it won't fling out on powerup and will shake the plane to pieces. Not a problem on pullers because the blades fold against the fuse)

Pretty simple really. The motor mount is only screwed onto the right wing half(you can see the three white nylon screws in that half). There is enough flex in the wires that they don't need to be unplugged although they can be if need be.

Looks nice, cheap is good If I might make a suggestion, trim the top of your motor mount round. It'll be a bit more aerodynamic, and allow more cooling air to get to the motor.

Am I the only one launching this by hand as designed? I haven't had any strikes. What am I doing right (or wrong lol)? Is this a real issue or another internet mythos like lipo fires and bigfoot?

I also launch it by hand, three fingers in the right holes, no gaz. When it is one meter away, full gaz... It works well, but always go against the wind.

I too hand-launch, and apply power when the plane clears my fingers.

I had difficulties launching because the props would sometimes not be able to spin up fast enough to get the plane flying due to the props trying to sort themselves out. Most of the time this resulted in expensive repairs to the Xeno power train.

Thanks to Bugman Jeff for his simple and effective modification to assure a good power launch.

No I'm launching it powered up.

I suppose it's possible to hit your fingers, but I'm wondering why I haven't? Just luck?

I give mine a good throw then throttle up. As long as it's into the wind, it seems to work just fine.

It is possible...believe me, pay attention!

I learnt on my blood that it is important to withaw down fastly your hand after the launch if you want to launch it powered
