Ok people,

I have my new Logo 6003D V-Bar about 75% built. I am now wondering about batteries and motor/pinion combos. I want to run 10s and I have a Jive 120HV to handle the amp draw 10s sees.

So, what's the recommended motor/pinion/battery for 10s?

I "think" it's a Scorpion HK4035-560kv with a 13T pinion. Also, 5s packs in the 3000mAh are the norm, right? I cannot find this motor in stock anywhere though. What charger would you guys recommend for charging two 5s packs at one time?

Also, does this 6003D come stock with mod1.0 gearing? I have no idea by looking.

Thanks.

4035-560 with 12t mod 1.0, many carry the motor
Yes gearing is mod 1.0
4000-4500mah is best on 10s, 3000 is to small indeed.

Ok, I'll focus my search on 4000-4500 packs then. Do you know of a vendor with that moor in stock? ReadyHeli, innov8tive, etc show no stock.

12T or 13T pinion with 10S and 560KV motor. If you plan on a headspeed above 2200, the 13T pinion may be more suitable. For 2000-2100 HS the 12T is it.

The Logo 600 flying members of my club using 10S have all gone to 4,000 to 5,000mAH packs. The 5K packs will give you better than 7 minute flight time unless your name is Kyle Dahl. If you plan to do mostly 3.5 minutes 3D competition flights, you can go with around 3,300mAH packs to save weight. Most of us would rather have the extra flight time with almost no loss of usable performance.

Look at the Xera motors as well. They have high quality bearings and great power. The 4025-3Y motor is 560KV, or you can go with the 4030-2.5Y (560KV).

13t on jive is overkill IMO. Also know anything over 1180 grams for weight on packs WILL need weight added to tail end to get good cog.

I presume I want to keep my headspead around 1900-2000. I will be doing regular sport flying with an occasional loop, flip, and roll.

ReadyHeli shows the Xera 4025-3y 560kv to be in stock. What is the difference between it and the 4030-2.5y 560kv (not in stock)???

Do these motors have flat spots on the shafts already for the pinion grub screw?

Some do some don't only takes seconds to mask end bell and file or dremel a flat spot. Yes your hs range for flying is ok but 2100 would be good target lower and you lose tail authority. Xera is comparable but not near as easy to service. Scorpions bearings and shaft can be replaced in only minutes.

O.k. so it's between the Scorpion HK4035-560kv or the Xera 4025-3y 560kv. It seems the 12T pinion is what I want regardless.

The Scorpion is easier to service but runs hotter and is less efficient.

The Xera is harder to service but has good bearings so servicability isn't too important?, runs cooler, and is more efficient.

Can I set the Jive governor to 2100rpm and still have plenty of headroom with either motor and 12T pinion?

Yes but I wouldn't say the xera is less prone to needing bearings changed out etc there are many here and many factors on those intervals in regards to timing on changing bearings etc...

That's not quite true. I have box stock 600. I use two different type of packs, 4000mAh Flightmax and 4000 mAh Turnigy Nano-tech. They weigh 702g and 625g, respectively. Times 2, both 12S setups are heavier than 1180g (1404g and 1250g). My CG is spot on. The lighter pack is longer and sticks out the front more. This added moment arm makes the two packs balance almost exactly the same. I actually have to leaves about an 1/8-1/4 inch gap at the rear of the heavy packs to make it balance.

No need to oil the Xera bearings. I would replace the bearing in the Scorpion first thing with a higher grade bearing and re-glue the upper bearing inside the case. There is too much slop in the Scorpion case from my experiences with the 4035 and 2221-6.

Both make great power and neither comes down hot using a Kontronik ESC. If you use the CC ESC, they will be about 65-70°F above abient if pushed hard. I have measured 172°F on my Xera 4030 and about the same on a buddies Scorpion 4035. You won't have this kind of heat with your ESC.

Are u basing cog on level boom or skids? I suppose with shorter packs maybe over 1195 may work, I've just never seen it.

Ok, I've decided on the Xera 4025-3y 560kv motor mostly because my favorite store, ReadyHeli, has them in stock! I like the idea of them being more efficient too. I'll go with the mod1.0 12T pinion.

Thanks for the insight guys!

I'm using a vertical main mast to determine CG. As I'm sure you know, having horizontal boom and/or skids is not relevant unless they are perpendicular to the main mast.

One of the great things about flybarless is that CG is less critical than on a flybar equipped heli. No one should misinterpret this to mean that CG should not be obtained on a FBL heli. It will fly better balanced. But compared to a FB heli being even the tiniest bit out of balacne, the FBL heli will compensate for minor CG issues amazingly well.

I suppose this is dependant on how anal you are, personally I want my COG within a 4-5 gram spot. The difference in level pirouettes and carry through on a maneuver on heli off balance by say 50 grams to 5 grams is a big difference IMO.

I agree. Everyone should balance their helis as best they can.
Eventhough the FBL system can compensate, it takes processor capacity that could be used for following the control commands instead of counteracting outside influences.

What does the winding number affect in a motor? For example, the Xera 3y vs. 2.5y?
