Which FBLhas the best internals?
Just curious and looking to get a better understanding of what's actually inside the box. I see things like 3, 6, and 9 axis gyros or digital vs analog sensors, processing power, etc.
Are some companies using old tech but masking it with slick setup software, bailout features, or a fancy case? I've used BeasrX units but have no experience with other units. What unit should in theory at least be the most accurate in flight based on the components it uses? Hopefully that makes sense.

I really think it makes little to no difference at the end of the day.
The old BX and VBar chips fly fantastically and have been and are currently used by the worlds best flyers in top echelon competition.

Went through the 3, 6, 9 thing... There are only 3 axis.
So 3 axis gyro, is just that. 3 gyros. They can be fooled by slow drifts. 6 axis means 3 gyros, plus 3 accelerometers. (Think gravity detectors) they basically know the direction of down. So they are used in auto leveling. 9 axis is 3G, 3A, as above, plus a 3 axis magnetometer. No clue on how that helps etc... Probably less fooled by vibration, but can be looped in to check accuracy of the other two. I think in a nutshell, it's checks and balances just like our government. Gyros slowly deviate over time but have no perspective, just measure changes. Accel provides perspective when it works, but vibration fries it. I think a mag is probably less accurate than an accel, but less prone to interference. With all three you can do more advanced stuff like auto level even if one sensor type is having issues. Eznov uses the 9 axis type. Anything that does self level uses the 6 axis type. (Except BD, which uses math, and the very old Revolectric Copilot which uses "eyes" that track the horizon somehow.) I like the ikon or MSH brain best. It's 6 axis and flies great as well as works with leveling too. Never heard any negative about BD 3SX, but it's over $300. As far as regular fbl, the market kinda died out. You got the cloned stuff, which is dead end (even if it flies freaking EPIC and costs $35), your Tarot / Copterx which cost $40-$50 and fly well, but not like the $100 plus options. Most vendors went to 6 axis and some form of bail out or self level. Used fbl market is great! Except for Vbar. Just make sure it will register and transfer if you can. (Get the serial before you buy, check with Mikado.) New guys are doing well too. Spartan, Spirit, have garnered a following despite being new fbl systems. Good luck! |

What type of chip does a Futaba CGY750 use?
Curious.

While the hardware in our FBLs is certainly important, let's not forget it's really the SOFTWARE that make the most difference. Selecting an FBL by IMU spec is probably a bad idea. It's the software, control loops, testing/debugging that make the most difference.

IMO - A Silverline VBar is superior to older black/blue VBars

I believe the Skookum SK-720 BE's have the highest level of technology and quality of components on paper, or at least the did within the last year.
How well they utilize that hardware in terms of software is very good and they are feature rich, however I wouldn't go so far as to say they have the very best software out there. I also wouldn't necessarily say that another FBL controller with lesser HW but software designed to work well within the HW constraints couldn't end up flying better.

This is a topic that interests me because I'm a tool and gadget geek, but i fly ikon and I'm sure theres nothing fancy in them, but every thing just works so wonderfully that I cant complain at all. I mean even my self level works in extreme vibrations. Like missing half a tail blade kind of vibration. I seen a thread where guys were talking about these chips and it was cool, so hopefully some of them chime in.

I think Skookum has great hardware. But their firmware lack quality. They consistently break things on firmware updates. Are impossible to contact, and rarely fix what they break. At least that was my experience with them.

I recently updated two of my helis to the latest firmware and they still fly great. Unfortunately I don't consider myself a highly skilled pilot so that opinion is only worth so much.

Chips are cheap, software is the make it or break it factor.

For me. Mikado does it the best. They don't have a flashy interface or anything like that. But they're stuff just works well. They don't release firmware that breaks things. But they are more than one guy in a basement somewhere too.

So are you suggesting that Art works alone in his basement?
Art was not working alone on the FBL code or at least he wasn't the last time I was shooting emails back and forth with him. BTW I've always gotten great support. We always hear about Uri with VBar development. I never hear anyone else's name brought up. Should I assume he is the only developer?

No. Skookum is a small company compared to mikado. That's all I meant.
As far as support. Well. There are lots of threads about Skookum not responding to emails and such. I had my own issues with them. They would say they would do something, and wouldn't. This happened repeatedly. With mikado. I put in a request. It's dealt with quickly and it's over. Plus. I'm not overly impressed with their help on the forums.

However I like some of the things Skookum is doing and consider them one of the good companies out there that are innovating and deserve credit for their accomplishments. Skookum is launching their new GPS-2 module with Laser Altimeter. They have been steadily improving this technology and I applaud their efforts! Their end goal is something equivalent to an invisible force field that keeps your heli from hitting the ground. Whether you would personally use that feature or not, it is pretty cool stuff. We need more than one company out there innovating and adding cool new technologies.
