I don't get it, why are you guys replacing your sensors? The new ones work the same and are just more vibe resistant.

Actually, the new Silicon Sensing Pinpoint CRM100 and CRM200 sensors are much better than the old Invensense 500 series sensors in about every way. It is much more vibration resistant, has almost twice the max angular velocity (900°/s vs 500°/s), changes less due to tempurature changes, are more sensitive, have both analog and digital output (Invensense is analog only), has a wider bandwidth, more noise rejection, etc. The list goes on and on.

Besides, I don't believe you can even buy the 2 axis IDG500 anymore. Although Invensense makes a 3 axis sensor ITG3050 that would work just fine. I guess it was a cost decision by Mikado and knowing that the Pinpoint worked well for Futaba provided confidence it worked well in RC use.

What is shocking is how inexpensive these MEMS gyro sensors are compared to the complete sensor unit. The 3 axis Invensense ITG3050 is only $12 in single quantity. No doubt much less in large lot. Although the Pinpoints are more costly at $20 for each CRM100 and CRM200 (3 total required as they are both single axis) for a total of $60 for gyro sensor cost in quantities of 1000 pieces. I'm sure Mikado worked a better deal.

OK, I have no doubt that they are technically better, but when you pull off your old sensor and put on the new one, you are not going to see better performance. So why spend the money?

Maybe it's just me, but I can tell my CGY750 equipped heli is quicker responding than my V-Bar equipped helis. The CGY750 is just a PIA to get working to its best. I got lucky with mine I guess as I only needed 1 major change beyond basic setup, but most people hate having to play with so many setting like on the 750. V-Bar has a much better user interface. I don't mind "lugging" a laptop to the field with me. That's how I check my data logger on the CC ESC anyway. I think many are going to be very surprised how much better the new V-Bar will fly. I'm confident I didn't just waste my $400!

I'm just sure you're not. They've changed sensors multiple times and it has never changed how it's flown. It's only been software differences that have made a difference.

True, but this is the first integrated 3-axis sensor ... the other sensors boxes had a 2-axis gyro for ail/ele and another gyro for the rudder (just all in the same box).

Among other things, not only is this new sensor considerably higher resolution, it's more vibration resistant, there's a long list of reasons why this sensor should make for a more locked in heli.

To early to speculate, we'll have to revisit this in a few weeks once some get out there and see.

It may fly better if you have high vibrations on your heli, but I'm with Nick. It appears to be running the 5.2 Express software that the Blueline runs.

it may be that they may not be better right now but with a little bit of firmware updating then you may see a dif in what are are now able to do.......

maybe ?

Correct GetToDaChopper!

From the Vstabi.de website -
The New VBar Silverline uses a new sensortechnology, which uses three sensorelements that are the only ones on the market specially designed and adapted for the use in real model helicopters.

The Sensors are manufactured by the Company Silicon Sensings and use a oszillating ring structure for the detection of rates in opposite to the known sensors that have only one or two oszillating masses.

The symmetric design and 8 separate sensing devices inside the sensor give a perfect ballance of the system, which enables to detect smallest rotational movements even in high vibration environments. This gives us the advantage to mount the sensor very stiff at the frame, so it detects smallest movements very quick without getting disturbed by the vibrations.

Every heli produces lots of vibrations if it is rotates quickly around the axes. This is fairly normal but can create a certain drift in the other sensor elements which gives a slight cross coupling through the axes. The new sensor gives advantages not only in nitros or tubine helis, but on dynamicly moved 3D helis as well!

The result is a very easy to use sensor with nice hovering performance, best possible vibration resitance and an superior dynamic behavoiur if flown in hard 3D. The full advantage will be available with the upcoming 5.3 Firmware release of the VBar which will be available soon.
The new unis is available at Readyheli, and can be purchased complete or separate (Sensor/Main Unit). The sensor is compatible with the known fullsize VBar main units.

Just being able to get the sensor only is a plus.

Well i was hoping they would be able to shrink it a little bit. This way the sensor would fit inside the frames of a 450 pro.

I don't have a 450pro but the new sensor is not as wide as the previous blue sensor. I would think the new one would fit.

I'm taking about the mini-vbar. Its about 3mm too big to fit in between the frames. The full size sensor itself would fit ,but the amp is way to big.

Which points to there being no difference in flight between the two. Mikado isn't going to be selling a mini that flies worse than the standard.

The new sensor is to take advantage of putting the best product out Mikado can and it will help a lot with guys flying nitro which mikado markets and sells the vbar for. The mini uses a different sensor that is not compatible with high vibrations a combustion engine produce.

I've been flying a mini on a Henseleit TDR for a long time. A few have tried mini's on nitro machines. No success at all.

The new sensor ignores vibes better is all. No one said it had a super processor that put signal out 100 times better. If you have a smooth vibe free heli like a Logo 600 there is no benefit. Ask Ulrich. Go to the Vstabi forum and ask the horses mouth. It helps nitro and vibration in general.

I still fly the older black sensor on my Logo 600. It was most sensitive sensor Mikado ever made. My heli is smooth. It works GREAT.

A vbar "magic" is in the software. Always has been. Sensor sends signal but then you have to do something with them.
