Power Systems for Logos, DATA & GRAPHS

Date: May 4, 2008
Helicopter & particulars of setup "servos,gyro etc": Logo 600 3D - Vbar

Setup style: 3D / Sport / Scale ? FAI: Light 3D + Sport
RTF weight if known: About 7 Lbs - will get acurate measurement soon :-)
Ambient Temperature: 20 deg C
Motor and Pinion: Orbit 30-12E Heli Expert - pinion 14t - http://www.plettenberg-motoren.com/UK/Motoren/aussen/orbit30E/Motor.htm
ESC "Brand and size":Jazz 55-10-32 - http://www.kontronik.com/index2e.htm
Lipo "Brand and Size": A123 MEC 12s Solderless Power Tube Packs - http://www.modelelectronicscorp.com/view_products.php?tid=2

Length of flight: 6 min
Headspeed: 1700 - 1950 - 2100
Motor Temp "average or on landing": cool
ESC Temp "average" or on landing":cool
Lipo Temp "average or on landing":cool
MAH put back into pack after flight: 2000

The machine feels VERY light and responsive. A123 cells are a great altenative for people who want safer packs and aren't into stick banging 3D.
The Heli Expert motor seems better than my other setup using a Tango motor which surprised me. It draws less current for similar flying style and seems to have as much or more power in the air.

I flew a Trex 600 last season with a similar 12s A123 setup and only got between 5 to 5.5 min per flight. It seemed like a heavy tank compared to the L600 Vbar :-)

Ambient Temperature: 20 deg C
Motor and Pinion: Hacker Electric Turbine 40-8-10L - 15t
ESC: CC Phoenix 80 @65% flat curve in high gov mode
Blades MAH 516mm
Lipo FP 3750 6S EVO 25
Length of flight: 5.1 min
Headspeed: Avg:2250
Motor Temp "average or on landing": warm
ESC Temp "average" or on landing":cool
Lipo Temp "average or on landing":warm
MAH put back into pack after flight: 2500

Soft 3D flight and bad collective management :) - Stupendous rate of climb and power - probably running too much collective ~13° and blades stalling before appreciable bogging = tempted to drop a tooth on the pinion and ramp up to 75% gov mode might decrease HS variation but will check collective and play a little longer but very happy so far - on these figures 98% efficiency :wow2: and flight duration 6:30

Notes: Good but not great power. My Z-30 has 500 flights on it. It started life in a Swift for 400 flights. After I retired that, I've put it in the Logo 500 3D for 108 logged flights. It's still going strong.

Hi!
This is my setup:
Logo 500 3D - VStabi
3xBLS451 - 1x BLS251
Jazz 80
OBL43/11
M0.7 - 13/153
VStabi: +/-12° / Adv-Mode
Esc: Idle 1: 60% / Idle 2: 80%

Log 1. Lipo: SLS ZX 6s 3300 30C
Log 2. LiFe: 8s

This logs shows my second and third flight with my logo. Just some gentle turns and loops...
Added a cooler for my Jazz and mainly fly in Idle2 right now, everything cool with these settings.

This is my L400 setup:

Logo 400 Flybar
3xDS520 - 1x JR8900G
Jazz 80
Hacker 40 12 8P
M0.7 - 17/200
Pitch +/- 13°
Esc: Idle 1: 70% / Idle 2: 85% gives 2030 and 2350 HS respectively

Intersting how power draw the same whether flying or hovering steady to check HS with optical tach
