Mikado Logo 600 Flybarless Electric Tips

From Mikado Logo 600
Important Tips
My Logo 600 main blade grip bolts were bending when I was running it at about 2200 (as in they got deformed) had to change mine to Titanium Main Grip Bolts from Hirobo (I believe they were for 60 sized Hirobo helis). I also had a few bolts in my kit that were bent/deformed even before using them! That would lead me to believe that the quality of the bolts supplied may be not as good, so please check.

The tail grip bolts (the ones that screw into the hub) are relatively small, make sure you replace them (and also the hub) if you suspect that they have taken any knocks or stress. And when you do, put as much blue threadlock (without overflowing it to the bearings/washers!) on the bolts before screwing it in. Also, use only Blue Threadlock as they work though oil and grease. As an added precaution, you may clean the threads in the tail hub to remove excess oil present during manufacturing.

Essentially, you'll notice that the tail parts are a little tiny compared to the rest of the heli, so extra precautions on the tail are always good. Other than that, most would agree that the Mikado's tail unit gives very good response and perfomance.

Securing the Tail Boom is important, you'll need to make sure that the bolts (4 of them) on both ends of the boom (the main frame end and the tail assembly end) are tightened sufficiently. After tightening, expect to have to re-tighten them again after a flight or two. Once the airframe is sufficiently broken-in you'll need to re-tighten the bolts less often.

Cyclic Servo Horns: I'll stick to the JR Super Horns made of good plastic (Nylon). Metal and carbon fiber horns tend to destroy other parts of your heli during un-planned landings. For example, I rather my Servo Horn breaking (< $1) rather than my Swash-Plate (> $100) (happened to me once!)

My Setup
Headspeed: 2050rpm (Governed by Kontronix Jazz, use a tacho to get it right!)
Main Blades: NHP Razor Pro 620mm (Carbon Fiber)
Tail Blades: NHP 100mm (97mm not as good, 105mm kinda too long)
Motor: Scorpion 4025-630 KV
Pinon: 10T Mod 1.0
Main Gear: 105T Mod 1.0
ESC: Kontronix Jazz 55-10-32
Batteries: Zippy 5s 5000mAh 15C x 2 (in series to make 10s)
Connectors: 6mm Gold Plated Bullets
Receiver: Futaba R6014FS 2.4GHz FASST 14-Channel
Cyclic Servos: JR 8717
Tail Servo: JR 8900G
Gyro: Mikado V-Bar V4.0
Weight: 3.66kg (RTF) 

Flight Times & Smart Li-poly Battery Management Techniques
Flight Time: Max 10mins, I do 6mins flights for safety (less stress on the batteries and you can quick charge them to 4.1v per cell - about 85% capacity - in almost 1/2 the time of a full 4.2v per cell charge!)

Chargers: 2 x Hyperion 0610i NET (Charges from 3.7v per cell - 25% capacity - to 4.1v per cell - 85% capacity - in 30mins with only 1C charge rate! Read - Faster charge + long battery life = more flights + less $$$ + more joy)

VStabi Settings
Here's the juicy part - my Logo 600 Hard 3D VBar/VStabi Parameter file for download - helidaniel-logo600-12jun09.vbr (right-click and Save As). Bear in mind that you have to adjust the trims and endpoints and possibly servo reverse to suit your heli's electronics and linkage setup. Also, don't forget to check your gyro sensor direction.

I hope that your Logo 600 flies very well, do drop me a comment or email (daniel@helidaniel.com) I'll do my best to respond.
