RC KTM Ascender by Phil_Maddox

Last crawled date: 3 years ago

Heavily inspired by some images from 2008 i came across on the net i have been wanting to 3D model and build this for many years. I've been working on this for nearly 2 years in odd moments when i have time
Update2 > uploaded the cosmetics ( tank, seat etc) All the new files have the number "2" as a prefix.
Ive also, alongside the original, added a 2 part version of the battery compartment for easier printing
Update1 > FC PDB base is now Rev1a = Original had FC board in stl Oops Good now
First test hops in the dining room,https://www.youtube.com/watch?v=I9EW7ZZrlag
The main frames are printed from ABS to be durable but this definitely isn't something that will survive hard landings or crashes very well.
I have only provided left hand side parts so certain items need to be mirrored
The main frame prints flat on a 200 X 200 bed It then carefully needs to be heated and bent . Info on bending attached in drawing
Obviously had to adapt a few things to make it fly but the core layout is intact.
Most joints are either solvent or friction welded
Here's a link to friction welding https://www.youtube.com/watch?v=Cj9TMmUldhc
I printed the main frames from ABS with 80% infil.
Once the main skeletal frame was built i adjusted for warping with a hot air gun
The outrigger struts ar 3mm OD solid carbon fiber rod and the rear yaw drive shaft it carbon tube 5 mm OD / 3mm ID
The equipment ive used can be found in the following links
