Simple racing quad frame with minimal components to print.

You will need to print

• 4 arms
• 6 risers (two types which you may chose, 50mm is the higher version for extra clearance)
• 1 lower plate
• 1 top plate

I would suggest using machine screws as a method of fitting the arms to the lower plate and then using nyloc nuts.

The top plate has been designed to accommodate a kk2.1 flight board, there is 2mm stand-offs already included in the print. The lower plate has stand-offs for a standard power distribution board.

The maximum motor diameter is 24mm, the arms where designed to take 250 size motors.

This build should fit onto a 200mm x 200mm build plate. The largest pieces are the plates which measure 60mm x 200mm x 4mm

~Update~

I have updated the arm design, after a few trials with my previous design I am not happy with how much they flex and also lack some form of ground clearance. I have rectified the design, landing legs have been added and also added a beading below to reduce the flex when under load. 'File name - armv2.stl'

You shouldn't require any supports as long as your print can cope with minimal overhangs.

I've built quite a few different sized multirotors, this one takes a lot of different designs into one. There is plenty of options to route cables to keep it as clean as possible.

The arms are designed to break off in the centre if you have a crash to reduce the impact force, they are simple to print and easy to replace.

The framework is tough, this is to protect the vital electronics. The risers are 10mm thick to aid in rigidity throughout the length of the plates.
