Hi guys, I pretty much set on ordering one to make use my esc and a couple of 5s batts lying around, also at the same time, wanna try flybarless for the first time and I figured the ideal heli to try on will be a logo 400se before moving up to bigger size flybarless helis. I've some setups in mind, therefore I need some advice to help me match one that suits my flying style.

1) esc - CC85HV ( took out from my decommissioned E550)
2) motor - scorpion hk3026-1600 or Hyperion hs3026-1600 or savox bsm4050-1650
3) servos - mks9660 or align d510 or hitec5245 or? (anything that can fit w/o mods to the frame.
4) flybarless - mini vbar or beastx or helicommand
5) tail servo - bls251
6) blades - edge 473mm / edge 86mm
7) pinion - 20t
8) batts - kong power 3200mah 25C 5s ( a couple that I had)

So yeah, these are what I have in mind. Please give me your advice and opinions. I probably am a sports flying, no 3d yet but learning how to do flips and rolls.

Thanks!

I'll comment on the power set-up. The standard Logo 400 commonly uses the 3026-1400kv or 1600kv motor, and targets head speeds of 2500-2800. As an example, Kyle flies his Logo 400 with a 3026-1400kv motor, with an 18T pinion (maybe a 19T...I can't recall for sure), at about a 2700-2750 head speed.

The Logo 400SE has a larger disc, and Mikado states a target head speed of 2200-2500.

So...your suggested motor choices of a 1600kv motor with a 20T pinion, will drive you head speed far too high for the larger disc of the "SE". It would be on the upper limit with the standard Logo 400.

In order to get the head speed down in the 2200-2500 range, you need possibly the 1400kv motor and a smaller pinion...especially for your stated flying style of "sport flying". 2500 head speed with the "SE's" 473mm disc will just make for shorter flights as you waste energy driving the head speed, and is not needed for "sport flying" and "soft 3D".

Note: My suggestion about the 1400kv motor and smaller pinion are just to get you in the "ball-park". Check things with a head speed calculator to confirm things.

Hope this helps,

Dave (-:

Hi Dave, thanks for the feedback. I just checked the headspeed calculator on rh and it seems that on 20t at 85%, my headspeed is stated to be at 2400, using 1600kv. You reckon I should use 1400kv and upped the pinion?

Btw, I am using 5s, not 6s.

"Btw, I am using 5s, not 6s".

Sorry I missed that. Disregard everything I said, as none of it is valid on a 5S set-up. I was speaking from a 6S perspective. Huge difference.

I've no "experience base" with 5S on a Logo 400...so you already know more than I do after checking the calculator (-:

Hey, that was good advice as I have the intention to go 6s once my 5s batts dies. Now it's a matter of deciding what servos and fbl system and the rest of the undecided items to use and I can start ordering the stuff in..

Hi Dave, did you guys test or fly anywhere the 400SE with the new Scorp 1070kv on 3300 6S at 2500rpm 470s and 72 or 86 tails? I mean the standard 400SE suggested components. Curious that I haven't seen many videos and most threads on all forums are about 400 stretches and not the official 400SE, which is on its way to me right now!

Good question, was also wondering about the new scorpion motor for the se. Would like to run it on 6s.

I rebuild my old Logo400 into a Logo400SE with the new Scorpion motor (4015-1070). I have rely big problems with high freq. vibration. I have almost concluded that then motor is running to hard.

I have a new Pyro 600-11 motor, but I am waiting for a pinion to use.

I can give you some feedback when I have tested the new Pyro-motor.

Regards

Thanks Erik.

I followed a thread where they mentioned the Pyro comes only with 6mm shaft now and for this size you only find 5mm pinions. I guess you managed to find a 5mm shaft. I would have loved to get the Pyro for the 400SE and discarded it because of that.

The high freq vibe is probably gear alignment (perfect 90º boom) as you might already know. If not you'll find info on Logo 400 vibration on all forums and it is always related to that.

What do you mean by "too hard"?

The shop where I purchased the Pyro motor promised me that it had a 5mm shaft. But when I got it, it was a 6mm output shaft

I have ordered some RevCo pinion and will try them to see if they fit.

The other night I was searching for vibrations on a Logo 400. I disabled the boom and had only the motor running against the main gear. Even if I had some backlash between the pinion and the main gear I had high freq. vibrations.

I backed off the motor (about 0.1-0.2mm) and the vibrations became much better. I had already replaced all the bearings, main gear, main mast and the pinion. I noticed the same with two different motors (Hacker and a Scorpion).

You can rebore a 5mm pinion to 6mm especially the 22-23T pinions can perfectly clamped in the turning lathe!
First drill on a turning lathe with a 5,8mm drill then use a 6H7 reamer to make the hole perfect.

I had bad expirience with Vibrations on the RefCo pinions (Mod 0,7), same setup with Mod 0,5 and rebored pinion runns smooth with no problams!

Some say the RefCo pinions have to be polished to run smooth!

Pyro 600-11 22T Mod. 0,5 -> perfect setup.
Will try the 4015-1070 with Roxxy 9100-6 and V-Bar governor next weekend

72 or 86 tails
86 Edge tail blades on my Logo400SE
They work very well, the 72s are a little too small.

I'm using a Hacker A40-10L 1100Kv motor
Only sports flying so 1900 RPM with an 18T pinion
08:30 flying time on Voltz 6S 3300mah batteries

Flies great.

Wait, you run 1900rpm? It recommends 2200-2500!

That's a matter of preference. 1900 is great for sport flying and slow 3D.

Wait so for the ice 75 then when i set it in governor mode, it has 3 governing headspeed modes...one for 30%, 70%, and 100%...so if i wanted a head speed of say 2100rpm, would i set the 100% mode to 2100, then 30% of 2100 for mode 1, and 70% of 2100 to mode 2? So when i set the throttle curve in the tx to 100% itll govern it at 2100rpm, correct?

My-Logo-n, you have a valid question but would be better off posting it as it's own topic in the proper forum "Electric motors-controller-esc". I'm sure you would get an answer.
