RE: RClander T33 for 90 or 120mm edf
I tested my Lander 120mm DF and Turnigy SK3 Fandrive combination using an 11s 5AH pack and a 12s 4AH pack.
The 11s setup (first graph) worked well, providing 3200 watts at 90amps. The 12s setup, however, had considerable voltage sag and only added an additional 300watts and 1000 RPMs. The voltage change under load was only 1.2 volts so I need to try a better 12s pack. I didn't have any other choices today as most of my packs are in cold storage at half charge. I didn't measure the thrust on these tests. The last graph shows both 11s and 12s runs so you can see the excessive voltage drop on my 12s pack.
The combination of testing in my isolated gym room and using the Castle Data Logger helped make things safe. The Lander aluminum DF also would help keep rotor blades from flying. I typically stand just outside the room when doing full throttle runs. Eye protection is always worn.
