Any one have data on Sapac's MB1s on 5s


I just bought some sapacs MB1 combos. Does anyone have any data like amps, thrust, and watts?

I fly my rclander cougar regularly using a sapac fan and MB1 on 5s. I have measured 100A peak and 1600W, lots of thrust but hard on batteries. My turnigy 5s 3600mAh 30C packs are only good for 3 mins of flight time. I hope this helps.

I have an MB1 combo in my T-50. Flown in on a 5s Thunder Power 45c 2650 a few times now. Also have a CC 100a Ice Lite ESC with it. This was my 2nd flight on 5s. I didn't measure the motor temp until I got back to the pits but it was around 100 degrees. It took about 3 minutes to get back so I figure the temp was 120 to 140 at landing.

Average Max at take off 101a & 1950 or so watts. This flight was 98.4a & 1804w ESC temp reached 168 in the middle of the flight. Abient air temp maybe around 90 deg. that day.



I think this was the second flight on 5s.

I almost hit LVC. I hit it white taxing back. I made 1 or 2 high speed passes I shouldn't have. but I did make it down OK.

I think I made the right choice.. Seems like the bigest bang for the buck. What about motor timing should I back off on it to keep temps down? I only hope to have performance like that very nice video, notice my name. This is what a jet should fly like, the guys at my club laborday are gonna hate me.
