HW 200A ESC and 850MX setup
Hello folks. I just finished my Top combo kit. I set it up with all the defalts of the HW ESC and exactly as the Microbeast plus calls for in the manual, i.e. +-12* collective and +-6* on the roll. Just wondering what you guys are using? I flew it once with the ESC set to store Gov and a flat 80% throttle. I think I want more like 85% (2170 RPM Headspeed??) Tell me about your ESC settings? Timing specifically. My ESC is running very cool and the motor is about 105* after a 5 min easy flight.

Data logger is the key.

I recommend open data logger file prior to anything else...and we can see what is really happening on your 700.

In My opinion, it is the best way to understand what is happening in your ESC, according to your way of Flying and parameter on ESC.

Ok, second flight and I recorded the data from the ESC before I powered it down. My setup: HW 200A Platinum with BEC; 850MX motor; two 6S 5000mha 100C Smart Batt's.

I fully charged the batts and flew for 4 1/2 minutes at 85% flat curve. The store Gov mode in the ESC seems to work great. Battery cells were all at 3.8v at the end of the flight. I could probably get 6 minutes out of it without too much concern with the easy flying.

Mild flying, tick tocks, full stick up and downs, fast forward, funnels.

Engine temp was 125*F
ESC Data: Max RPM=111x1000; Min Voltage 41.2; Max temp c048; Max current 0138.
Thank you for your input. I really appreciate it.

It is very difficult to improve your numbers!!

4.5 min flying... Very good!

Forget about 6 min since only my mother in law can do this time doing hover.

I would Continue doing some testing with less collective.
The data logger relate max Amp with flying time so, you can figure out what maneuver consume more amps... So watch it!!

Datta logger is a powerful tool so, don't compare your numbers with other pilots because it is not relevant.
Compare your number with yourself.

I don't like to mess my rc helis with my pc but... Data logger is very helpful.

By the way, you don't tell us about pinion and spur configurations.

As you can see, your electric monster is full of torque!

So, that is why you must consider spend some time lowering the collective till you feel confortable with it.

To increase your flight time, also consider a very low start up.

Leave your packs at 3.8 volts per cell, 30%, is a good practice.

You must review your trex700 autorotation configuration.
I don't feel confortable with electric big birds doing such a maneuver.

What did you do about it?
