It has to do with gain. Nitros operate linear on the throttle where gassers operate in a very arching curve. Nitros also respond quicker. We tend to have to lower the gain so the governor doesn't think something is wrong and shut down. When things aren't setup properly you end up with a governor turning itself on and off and getting hickups in the throttle.

Futaba governors are the governors of choice because they allow us to modify these gain settings. Other governors have gain settings but are still unable to work with gassers...such as the MultiGov.

It's very tricky stuff.

I think the key thing here is that if you make a FBL unit that works extremely well with gassers without modifications or heavy tweaking, then it will become the defacto standard equipment for this niche market segment.

A simple solution is to make the governor selectable as a governor or limiter. Limiters work perfectly on gassers. The most consistent headspeed I've ever achieved on a gasser (My Spectra G) was with a Revmax. Dead simple setup, too.

Several pages back, probably near the start of this thread, I explained the reasons why we may not be able to make an effective vibration analyser from the same sensors that we use for flybarless stabilisation. Today I came across this video which is a perfect example of what I was saying and simple demonstration that not all MEMS sensors are the same.

To avoid confusion, the Vortex VX1 is not using the AD sensors mentioned in this video but our chosen technology is also designed to offer high vibration immunity. I am using the video as an example only.

The Spartan FBL unit makes yet another strange appearance....

Here is a little recreational project I coded this evening. It is largely based on the electronics and firmware of the Vortex VX1...

Thats cool but we just want one for our helis!! Good luck with the plank guys, hope it exceeds expectations

It's getting there! As for the flying wing implementation, it is just for my recreational flying (at least for now). I am curious if it is possible to have effective rudder controls using this type or airbrakes. The idea comes from stealth bombers which use similar breaking system for rudder control to avoid using vertical rudders that reflect radio waves and make the plane visible to radar.

Angelos, I hope you know my last post was tongue in cheek attempt at humor. Just anxious to get my hands on your new product.

I think it's very cool that it can be adapted to other uses, and that you are developing the software and experience for unusual application installations. Sorry if I came across wrong.

Figures you'd reverse engineer the B2.

I think there is a market for 3axis stabilization for plankers, the trick would be the marketing aspect ... plankers are cheap buggers

The park-flyer plankers in my club sure seem to be. The guys with built-up models, multi-cylinder power, larger scale guys don't spare much expense.

I just gave a planker at my club one of my old 2100t tail gyros, I think he is going to use it on his ailerons or rudder for one of his crazy fast EDF. If creating software for the VX1 that allows it to be used on plank doesn't distract from the work on helis it can only be a good thing.

Don't worry about it; I realised what you meant. I just wanted to clarify that there was no strong commercial interest at this time. Just playing with the idea and see where it leads.

Incidentally, I maidened the X8 today and what a wonderful plane it is. Probably the most precise plane I ever flew and does some wonderfully elegant turns without any sign or tip stall. It will be fitted with FPV gear during the weekend.

Now that you posted this on a public forum, probably 10 Chinese are already working on it.

There's nothing I know of that can offer that level of control sophistication, but it is a fairly niche implementation.

For general 3-axis gyro stabilization there are several good options already for planks at far lower cost than it will ever be practical to sell the vortex, but perhaps there is a higher end market interest there worth exploring.

Good luck with the FPV maiden of the X8 Angelos - I'll have to show you my new FPV project sometime! I can't wait to get it all up and running.... I think you'd like it!

I'm getting rather keen, I'm eyeing off the mini Vbar on the Protos and thinking it'll probably be the first to get the flick.
I also know the Protos is a solid little heli and will be the ideal candidate.

I take it we've all seen this already??

Been around a while now, a right bugger to set up
