Just managed to get my prop back from my friend today who got the hole enlarged to 8mm?!? Thank god for him coz I wouldn’t know how to get it drilled without having to bring it to a machine shop. Anyway I managed to hook up my WattsUp Meter to my Yak55 and got some readings off it. Specs as per below:
- SWANG 480Kv Brushless Motor + 80A 5A BEC ESC 158U
- RHINO Battery 3700mAH 5S1P 20C
- Turnigy 17×8 Light Electric propeller
Max Amp: 54.46
Wp: 1049
Just as a comparison from my previous post with a 16×10 prop:
- SWANG 480Kv Brushless Motor + 80A 5A BEC ESC 158U
- RHINO Battery 3700mAH 5S1P 20C
- TGS Sport 16×10E Precision propeller
Max Amp: 52.08
Wp: 923.3
From the looks of it… its not overdrawing any Amps for both the motor/esc & battery. The only problem is… there’s actually very little clearance of the prop from the ground. Especially hard not to scrape the tip on fields with loads of pebbles. Probably need to increase the wheel size perhaps 
Happy Flights all!
