Thanks for the kind words Rob,

I am always happy to share my knowledge as long as my input is appreciated.

There are various way to make a nimble Logo. I have experimented and concluded these are the factors:
- blade length, cord size & weight
- voltage (6S/8S/10S/12S/14S) vs disc load
- rotor mast height
- HS (lower HS + more col pitch vs higher HS + lower col pitch)
- FBL settings

The key is weight and the battery packs are the biggest factor. ESC/BEC and motor can makes the difference of 50~80 grams. Sometimes using what we have (like packs we already have vs packs that are Correct in size) can offset all the benefits of higher voltage setup. Spending energy just to fly around heavier parts are inefficient. So unless both heli's are setup exactly, FBL settIngs and little variations in weight/distribution can affect flight characteristics.

My latest project is my Logo 500SE with 603mm FB on 8S 4400mah. As fast and nimble as my Gaui X5 but with better visibility and power.

- 8S are from my damaged 6S and 7S packs
- single discharge lead like a 6S pack
- I charge the 8S packs either on my PL8 or Duo 4010 per channel
- Logo 600 canopy
- 25mm boom
- SX head but no Counter Bearing
- Logo 500 blade grips
- Logo 500SE boom and belt
- 2250 HS @ -/+12 collective
- 10 degrees on the cyclic
- 4:30 of solid 3D flight time with 20% left over
- nothing over 109 degrees after flight
- HC3-SX / Jive 120+ HV with internal BEC @ 5.6v / DS610's
- X Era 4025-560kv 5mm shaft (over 90% efficiency)
- Mod 7 main gear
- ridiculously low disc loading
- plenty of power and pop with proper collective management
- very quiet and I can get 7 min @ 2050
