MOTOR MOUNT - APPRENTICE STS

If you are used to fly RCs, you will have noticed that the incidence set for the motor in this plane is very high.

Incidence down: given by the firewall Incidence right: 6º (if you go for the 5,5º incidence mount, you'll need to sand a little more)

What infill should I set???

Good question!!

Let's follow this rule of thumb:

If you are an experienced / skilled pilot, your landings are smooth, and you don't really need the SAFE assistant when flying, then you CAN set infill to 100%

If you are a novel pilot or not skilled yet, don't worry, you will be soon. Until then, you SHOULD print a "breakable" motor mount.

Go for something close to this: 10-15% infill 2 walls (2 x 0,4 mm) 2 or 3 layers at the bottom, depending on whether you need to sand or not 4 layers at the top ---> remember you have to sand the top surface to smooth out the layers before mounting the motor, so as a result of this there will be a small loss of printed material. Layer height: 0,2 mm

Why a "breakable" print for unskilled pilots? Well, you better break this motor mount before cracking the firewall. The firewall is quite fragile: to big, to thin and there's no isogrid or similar at the back ...

Enjoy printing! Enjoy flying!
