Well done Jurgen .... every replacement shaft should come with a new shaft to motor adaptor ......

You may remember I had to replace my CF shaft after a handfull of flights ..... it was a pain in the $$$ to get the old shaft out of the adaptor .... I ended up using a vice ..... a small blow torch and a set of Mole Grips ...... Oh, and a suitable drill and 1.5mm bit to free up the vent hole in the adaptor .....

I really should stop using high quality Epoxy ....

Have you any idea ?

Thanks

Finished my own carbon motormount in KD-style. Took some time because the guy where I cnc'd the parts by accident used 2 mm GFK instead of 1,5 mm. I then ordered 1,5 mm carbon at Hobbycity; very nice and very cheap.

I'm very happy with the results so far; very solid and looks really professional - 'will post some pictures when everyting is ready.

Also had some thoughts about that. You need pretty long legs since the prop is mounted on the read of the wing. And long legs provide an awful lot of drag. So I was thinking about retracts like these at HC. Enough ground clearance for a 9" diameter propellor. But the project got cancelled because it will snap the retracts when landing on a bumpy grassfield like our clubs airfield.

Landing Gear for XENO


Thanks Sleurhutje,

I think something simple that can be add or remove.

With some thin weels I think than aerodinamique will be not affected very much.

Well; I have a few things to do to the airframe and I'm waiting for a few centimeters copperwire as extension between the motor and esc. Maybe next weekend!

Just fired up the Hyperion outrunner for the first time; 12 Ah with the Aeronaut 9x5 folder. Should be enough, but I'll order the 10x6 sometime. The motormount and carbon prophub (own design) works perfect; everything is extremely light, solid and the folding prop works without significant vibrations...

That kind of landing gear would not provide enough ground clearance for the model to rotate without the prop hitting the ground.

152mm should be enough for a 10" prop. So with a 9" prop plenty of clearance. The prop isn't in the middle of the wing but even a little higher.

yeah, but I think you need the nose to point a little upwards, which compensates that

if the purpose of a lg is only preventing bloody fingers, you'll better consider a bungee

Why would you need a bungee for a glider? If you are afraid of the prop, just launch with the motor off and it on at a safe distance.

I can throw my Xeno and fly a 360° circle without any motor power at all.

Agree, but I can't think of any other reason why somebody considers a lg on a Xeno

I think the lg only for landing on ground. Not for take-off.

How you landing on the ground ?

If there good grass on field, it's ok, without lg.

In this case the nose to point a little down it's ok.

Just add a little padding on the bottom of the fuselage when you don't have grass to land on and don't point the nose down when landing.

I bought this plane and I have no idea what to do with it. Based on this thread, clearly there isn't an inarguable best solution that results in precision and performance... unless one performs unique re-engineering... the cross supports without the shaft seems like the only viable solution. I wish it came in a box as I'm not yet retired...
