I posted this on RCGs, but I thought I would post it here as well as I am not sure how many of you goto those forums.
After smacking my Blade 400 around pretty hard over the last two days, I decided I had better log a flight or two to make sure I wasn't over doing my ESC, Motor or Batteries. So here is the data for you all to look at. I put it into 4 different graphs as it is just easier to read that way.
My setup is as follows
Stock Motor
Stock ESC
LoongMax 2250 20c Lipos
HXT 9 grams Servos
Futaba 401/9257 on the tail
Align 335mm Pro Woodies
The flying I did on this pack is the same as seen in my video in my last post. I did fly it harder this time though. I really wanted to work the heli to see how it would pan out. There was alot of loops, flips, rolls, Full Collective Climbs, High speed passes. Generally, just banging on the heli pretty hard.
After reviewing this data, I feel that the 10T pinion is just too much on the Blade 400 for my liking. I do not like running my helis at or around 3000 RPM. I like to keep mine more in the 2700 RPM range when I am flying it hard and more in the 2400-2500 range for just general flying about. To get these HeadSpeeds, I am having to really drop my throttle curves down. Doing this pulls the motor out of is power band where it performs the best and is most efficient. A 10T pinion is just too much for this motor IMHO. So I will be putting a 9T pinion on this motor and testing again sometime this week. I am sure I will be much happier with those results. It will bring the Max Amp draw down, allow for longer flight times and keep a more consistant head speed. At some point I am going to replace this Stock ESC with something that has a Governor on it as I got spoiled by the Governor on my Scropion ESC I have on my Dragonus. Having consitant HeadSpeeds throughout the flight makes it alot easier to manage your collective. I in no way feel that this ESC is not up to the job, I just miss having a governor.
So here are the Graphs.
