Recently purchased a $15 watt meter on Amazon that had good reviews.
I used it on my Das Mini Stick scratch build from the plans forum and it was pulling way higher amps than expected.
Motor: QAV2206-1900kv https://hobbyking.com/en_us/qav2206-1900kv-cw.html?___store=en_usbn
Prop: 6045 bull nose
Batt: 3s 1300
Esc: Turnigy Plush 12 amp
Now according to HK this combo should be around 12 amps (from the HK page). I showed 18 +/- amps and 200 +/- watts on the new meter! I have been flying the plane. Quite a few times in fact with no signs of letting the smoke out.
I also tested my FT Mustang w/ NTM 28-30 1200 and 9x4.5 and came out with an as expected 250 watts.
Something doesn't make sense about the Mini Stick test. Is it even possible these numbers are correct? Wouldn't the ESC have burned up in a couple flights with a 50% plus overload? And could the published prop test be so far off? And if the watt meter is junk why do the numbers on the other plane look correct?
