I was wondering if I was trying to reinvent the wheel...I'll will see what he says!

Let us know if you hear anything... I might be interested in doing the same thing...

How are you planning to weigh these airplanes?

How do you expect to get the engine power or thrust?

For weighing, I was thinking some electronic scales would do the trick. They dont need to be excessively precise. Any other ideas?

For engine power, I'd like to use power charts where available. Some engines just arent going to have those available, so I'm shopping for ideas there too.

Thrust we can calculate and/or measure directly

Default < $100 Arduino / Bluetooth / GoPro Mount Sensor Pod

Last year, for EAA's Founder's Innovation Prize competition, I made a < $100 sensor pod with an Arduino variant connected to a differential pressure sensor, with Bluetooth to an iOS App. The general idea was that the pod would attach to a GoPro style mount and provide pitot static data to an iOS device and cost about as much as a "Stratux" DIY device, but for pitot-static and other flight data instead of ADS-B.

I did not get selected by the EAA -- other similar things were selected to present during AirVenture. However, other than the $2000 Levil BOM Pod, I have not seen anything further in this space, and nothing further from the other EAA Founders Prize Finalists.

I have not tested it in flight (I just got a steam-gauge RV-6A that I may try this out on once I get transition training and comfortable with the airplane), but, when I saw this thread, I figured I would share this for educational/discussion purposes here:

This...
https://wingbug.com
also looks interesting. Not sure if they are for sale yet, but they had a few units at Sun n Fun. I believe they said raw data was captured on the iPad and was exportable.

I have no connection or experience with them.

Good luck, sounds like an interesting project.

I hope to have a WingBug to test soon, and if that happens, we?ll let everyone know how well it works!

Have you looked at Levil aviation?

Sounds similar to this. http://www.spingarage.com I think there's been a Kitplanes article on it.

I did something with altitude several years ago... never really followed up with the idea though.

I have a set of sensors I was going to use to make a pitot tube and a set of gyros etc that I was going to use to make a bank turn and artificial horizon. I'll have to dig those sensors out of the box if you want to know what they are. The one sensor had two vacuum tube ports on it so you could hook one up for static and one for "ram air" which would give you all you needed for airspeed.

AOT sensor would be easy enough basically a potentiometer like a fuel sending unit.

The one thing I found at the time alot of the other projects on the internet the formulas people were using was wrong to calculate the altitude of pressure, or didn't adjust for baro. So I derived my own formulas.

EDIT:

The sensors for airspeed

or if you want the tubing etc

diydrones has one also
