Aerobatic flight with SKYVIEW

[Invertidus]

Hello.

I am currently finishing a project airplane and have been following the development of the SKYVIEW. I am truly impressed with the information I’ve seen thus far.

I am building an aerobatic airplane which is capable of over 300 degrees of roll per second. It is also capable of high G´s, both positive and negative. I have read through the forum and it seems the current ADAHRS might not be able to support these roll rates. I don’t need a system that works flawlessly during acro, but I don’t want the EFIS to be rolling on its back after a few minutes of acro when I need to come back to the airport. Would you please explain the limitations this system has when it comes to flying heavy aerobatics.

I have read through the ADAHRS post and you mention price as a factor to not building a more capable ADAHRS. For those of us willing to pay to get a more capable system, do you think this might be available in the future? Maybe as an upgraded ADAHRS module that can be easily replaced? Is something like this in the drawing board. This would be a major convincing factor for me and a few other acro junkies.

Thanks, and congratulations on the SKYVIEW launch.

The current AHRS just takes a few seconds to resync even if you exceed the roll rate so I suspect in actuall practice, it would work just fine for you.

The new ADAHRS is 150 deg/sec just like the current ones. Exceeding this doesn't damage anything, but it does cause us to lose track of "up." Once you hit anything near straight and level and coordinated for a few seconds, it comes back.

The tradeoff to higher roll rates is a bit about cost. Sensors that read higher roll rates aren't more expensive- but they aren't as sensitive. So if you really want to do it right, you now need multiple sensors, which is is a whole new design. We don't think there is a big enough market for us to undertake this design, especially given the current design recovers gracefully. We're already in plenty of acro planes, and as you say, it doesn't need to follow you in the maneuvers, just when you are doing cross country work, and it works awesome for that.
