Also, it would be great if you could share the spinner model or the link.

hello, I have the same motor and I want to use a spinner but I don't know what should be spinner's aperture. 6 or 8? Can you share this information, please?

[@keremgulpnar517]

what propeller would you recommend to an UAV that has 2 480kv's? like nimbus 1800

Hi Kerem
to choose the right prop for your motor please look it up on your moto-specs. I always try to keep current as low as possible on cruising speed. Weight to Thrust bether than 50% depending on the plane. But not every Propeller is what it is... thats why I testing it like you saw on my video...🙂Clear skys!

@@hb9hal you're right man. Thanks for taking the time

Hello, I have the same PIlatus, did you encounter any problems because of the height of this Pichler landing gear (adjustment of the incident angle)? What about the quality (landing gear) ? Thank you.

Hello Hobbyflight
The Landing gear was my bigest consirn. I have had to modify it a bit. Make sur nothing blocks it so that the endpoint switch applies.
Even If the wheels are too thick you may get into huge problems.
Second consirn seems to me the frontgear. We printed a 3D push road clamp. I showed it in my previous PC-7 Video ( Notice timemarker in the description).
Unfortunately my perfect landing with reverse thrust was not cought on camera. It was my best landing ever and everything worked just fine.
