bionic 24

[amdemby@pol.net]

I have a logo 10, and see alot of you guys flying 14's....Is there anybody out there flying the Bionic 24? Is it really a 3D machine? Is it worth the added expense?

[OICU812]

I honestly do not know anything much about the Bionic 24, from my understanding it was not designed as a 3D machine, it does not have driven tail either to my knowledge which really tells me it is not. The 14 is Logos best machine imho as I have flown every other one, just never the 24....

Hello, well I'm building one right now. Here's the link:

It was time to retire my L20, so I thought why not give the Logo24 a shot? I'm positive that it is going to rock. The only downside I see for 3D this far is that it does not have a driven tail, but other than that it should rip. I guess I'll find out.

Hey Carlos', glad to see you building the bionic, always wanted to see one, and now I will.... :glasses2:

You are gonna love it, I predict that anyway....Gordo... :)

Hi,

my name is Stefan. I'm from Germany and I also have a Bionic here waiting for the first flight. I bought the kit a few month ago on EBAY for a really good price and i also would be very interested if s.o. could give me a good setup for the machine.

I have a "Logo 10 3D" with Plettenberg Orbit 20-10 Motor flying with 5s Lipo and V-Stabi Virtual Flybar System which has great power. So I am thinking about a 10s Setup for my Bionic with 2x 5s1p 3700 Flightpower cells.

So, now as I found out, the L14 has the same rotorhead as the 24, I would prefer Plettenberg Orbit 30-12 or 25-14 or Köhler Actro 24-4 or 32-3. But I am really confused which one to take?!
I have seen a Video of Markus Kim flying a Fury Ion, a 90-Size Heli, with Actro 32-3 and 10s Flightpower 3700. So I don't know if the Bionic will stand this power or if it will be destroyed in the air :twisted:

But I have also seen the German Factory Pilot of Mikado, Andy Rummer flying the Logo 14 with Orbit 30-12. His machine has absolutely Extreme power and I think this Motor is similar to the Actro 32-3, although it's more suitable for a 90 Size machine.
So I'am not sure which Motor has the best perfomance. I have seen some Raptor 50 electric conversions flying with Actro 24-4 or Orbit 25-14 which also performed very well.

Now what do you think, what would be the best? The prize difference between the 2x and the 3x Motors will be 10 bucks, that's not the problem. And the kV-difference is also about 50 rpm. So who can explain me, what's the real difference?


One thing to talk about would be either, that MIKADO warns in the Bionic Manual not to exceed 1600 rpm Headspeed. I think that's just a bad joke, because the L14 has the same Rotorhead and those factory Pilot guys fly it with about 2200 rpm. So the L24 Bionic is an Old Model and the manual was writen in 2004. Maybe those guys did never think about flying extreme-3D with their 24 NiCad-Cells?!
I think using a L14 Setup would also fit to the 24?!

The other fact is, that a Pinion with less tooth will maybe kill the maingear in a few flights. So a Motor with low rev would perfom better on a low Gear ratio.
By the way, I've got the small Bionic with 600mm Blades, so it would be really be similar to a 50-Size-Heli.


Maybe someone out there has the clue, I would be very thankful for some response. I never thought it would be that problem to get some good Setups, but it really seems that nobody is flying the Bionic. Even here in Germany, where this Model is produced.
I'am quite sure (I really hope), that this thing is absolutely 3D-capable, first of all the L14 is nothing else than a newer Version of the Bionic.

Greetings, Stefano. :noteworthy

Hello Stefan, I just got back from IRCHA-SE where I managed to put in a couple of flights in my Bionic yesterday with the EspritModel guys.

Like you I'm just starting to play with this machine. I am also looking for some HOT 3D performance. I flew it on 10S 3850 Extreme packs, Tango 45-06, 8t pinion and 600mm MS blades. The headspeed was tached at somewhere above 1900 rpms (in hover) at 95% gov. With this setup the Bionic flew very well. It felt very light and powerful in the air, but it still didn't compete with the latest Logo14 setups. Unfortunately the cold weather was affecting battery performance, which convinces me to try another couple of flights here in the hotter Florida weather.

There are a couple of things I will do to increase performance. First I will change pinions from 8t to 9t, aiming for a headspeed of 2100rpms. Secondly I will switch batteries to 4600 Extremes and see how it likes it. I believe this non-stretched heli has some good potential with the Tango. We'll see.

I'm positive the Orbit and Actro motors will work equally well in the Bionic as they do in the 14. Not sure if the handling will be the same though. So far my Bionic, although it flies great, it does not feel as smooth as my Ion-X. I will try and get some video footage of it in the next week.

Hi Chachin,

first of all many, many thanks for that Flying-Video. Now I can assess much better, how my Bionic will perform.

So there is no doubt any more, the Bionic has no problems in twisting and turning around. Did you also fly some more extreme maneuvers like Kaos or TicTocs?

Seeing you just doing some smooth and wide-range 3D-Flight it seemed as if the Bionic is some kind of comfortable and not very agile. (Hope you understand what I mean :oops: )
But maybe the 45-06 isn't really the right motor. Perhaps a 45-07 would be more crispy. It seems that in the climbouts the 06 starts to bog more or less.
As you said, this can't really compete with the L14.
So maybe you're right with turning the Headspeed higher.
I had nearly the similar performance with my L10 3D at 5s first. Using one tooth more on the pinion brought incredibly more power.

I also heard that using the Raptor 90 Flybar and the Red Raptor 90 Light Paddles will help the Bionic/L20 to a much better cyclic response (I will use the VBar-System at any rate and so I don't bother about the slow cyclic)


To sum up, I believe you when you say the Ion-X is more smooth :smokin: .
I have seen this Video in which "H to the C" and Markus Kim are rockin' the Ion on 10s with Actro 32-3. That's really smooth :twisted:
So I am looking forward with pleasure to find a very good setup on 10s for my Bionic (the Actro with 3,2 kWatts will be too extreme for me and my batteries).
In any case, now I know that the Heli won't be the problem. Again, many Thxx for that Information. :noteworthy


By the way, you're running the Mod 1. 96 tooth Main Gear, aren't you??


Greetings to the Sunshine State and also to the rest of the U.S.

Hello Stefan, glad you got to see the video. I know exactly what you mean.

I have not done any Chaos or really hard tic-tocs yet. This is only its 4th flight and the hardest I've flown it until now. I am also in the process of learning chaos. I should be able to do it with my real helis very soon. However, I did try a few large tic-tocs between the 3:00 and 3:08 minute mark in the vid. It may be hard to tell since there are no points of reference.

So yeah I'm still in the process of tuning it right now so it's not fair to judge the heli too much by this vid. For example in this clip the piro rate as well as the cyclic is still too slow for my likes. I need to change headspeed, main/tail blades and flybar paddles which should make a big difference in performance. I guess it can't compete with a 14 because it's not setup like one yet... hehe.

Yes, the 45-07 would probably deliver some more pop on an 8t pinion. And yes I am running the thick mod1 gears (96t main gear) since I've heard anything else may strip out too easily.

Now the V-bar should make a real difference!!! Let us know how it performs! :shock:

[Chachin]

Also, your name sounds familiar to me for some reason. Do you fly for Mikado??

Chachin..

[Stefan Hornstein]

Hi again,

unfortunately I'm not sponsored by Mikado :(

But I've got some good connection to one of the VBar - Producers (he is a good friend of mine (a veryvery good friend and he is very interested in my test-flights).
I will report back when my Bionic is ready to rumble,

'till then,
Byebye.

And don't hesitate to report your latest realizations here!!

[Chachin]

Did another flight yesterday after some more tuning on the Tx. This heli is actually getting pretty sick :D . The increased piro rate made a big difference in how aggressive it looks. The hot FL weather has livened up those packs a lot too. I tried my first set of piro flips yesterday. Did a couple of complete flips and it handles it well. I also did some aileron tic tocs, no problem. I will practice some more this week and get it on video on Sunday. This Logo seriously should have no problem performing those maneuvers.

I am happy with my "bionic"
