Thank you to the team at Monto RC Hobby for contributing 4 Avroto 3520 400Kv motors to our Autodesk University Multi-rotor UAV Project.
While researching large scale and heavy lift Multi-Rotor UAV's in the RC Groups I read Stephen Clinch's review of the Arvoto Lift Series motors. I was impressed by designer Andrew Raines 21lb Hexacopter and wrote Jim at Monto to discuss testing out his engine design on our project.
The biggest design challenge for the Medusa Project is that the final UAV build weight is still undetermined. Only when we completed the 3mm ABS 3D printed exoskeleton and CNC the 1500mm air-frame can properly configure the UAV's power system. This major factor focused our design effort to develop a Power system that would push the upper weight limit of off the shelf UAV components.
I added the Avroto 3520 400Kv motors specs from the Monto RC Hobby website into Ecalc to get a comparison to other motors I was researching and the numbers came back very favorable. 8500 grams at 62% Throttle for 5 minutes.
Our next step will be to add the motors to our full scale PVC prototype to evaluate their performance with 16.5 and 17.5 Props.
