why is my 550e a pig
looking forward to my first large e bird was disappointed at performance.

castle 75 set to 2200, is this too little HS?

should I step up to 18T pinion?
should I run 8S?
should I run 14+- coll, 14 cyc at current 2200 (pulled this one out of the align book)?

confused, need help.

it is:
stock 550 kit
stock servos at 6 v through castle bec
align BL-600MX motor (1220 Kv, 6 poles)
castle phoenix 75 on "set rpm" mode high HS is 2200
45c 6 cell 4000mah pack
Vbar
550 mm blades
85 mm on tail

if you can help...

Tell the castle you have a custom battery, at 4v per cell, 6 cell.
Stick with recommended 3D pinion.
Shoot for about 2600?

2200 is a bit disappointing. I went from stock Align ESC at 95% flat to ICE and saw 2200 was max it would let me set. Headspeed made the 550 a bit piggy. So I followed advice from a Curtis video and just told the ICE I had mode voltage that 3.6v/cell.

You headspeed is way too low. For the three flight modes I use 2200, 2400, 2500 and a 18t pinion.... BTS

I’m not 100% sure but won’t entering a bogus voltage mess up the governor or does it just ignore it?

No. The voltage value is used by the setup software to give you what it feels is an effective governor range. The ESC just tries to make that speed work.Jim Senicka

Your a genius!

Thank you soooo much, I managed to get an 18t pinion, 2800 high head speed, 2500 mid HS, bird rocks!

motor, esc -- lukewarm at best; batt 100 degrees at most.

awesome trick, thanks bro

Just be careful over spinning Align blades. I had a weight fling off a 425D blade at 2600 (their highest allowable HS).

although I like align's "cord forward" aggressive blade attitude, I no longer fly them.

right now I have rotor tech 550's on, changing them to edge 553's when I have a chance.

to be specific 2780 is my high HS, wow, very violent. I have yet to dial the cyclic in, maybe 10 or 12. Collective feels great at 12
