I think you got the prop sizes reversed. The 13x7 should be used on 3S and a 12x6 or 12x6.5 should be used on 4S. One site says the motor is a 920KV and my quick calculations show a 13x7 or 13x8 on 3S and a 12x6 or 12x6.5 on 4S. Of course, I'd check the rpm, current, and watts before flying.
Update: eCalc confirms the 13x8E on 3S and a 12x6 on 4S, but both push the ESC above 40 amps on the ground (zero airspeed). However, that's calculated, not real..
I used info provided by the website. OMP has 2 websites. One with wrong info and one correct. I flew additional flights on that prop with 4S without issue. However now i have 12x6.5 installed.
great looking plane !!! have a good one...
Agreed! Thanks JCB!
