Using your phone for a pitch guage
I bet a few of you guys could inprove on this.

Im gettng old and was having a real hard time lining up my pitch guage. So I made up a digital guage using my phone. The side of the phone is flat and butted up against the paddle clamp so I knew it was square.

I used a few popicle sticks and some 3M indoor outdoor double sided tape (love that stuff). I stuck it to an old pitch guage clamp.

Worked like a champ.

As you can see in the last picture I also tried it by just using rubber bands butted up tp the side of the phone.

I seen a camera app for the iphone for pitch but I wasnt sure if it took in account being off center with the camera. Plus my hands are not steady.

I did end up purchasing a real digital guage but this actually works.

That's pretty good!
I wonder if you took the blade off maybe you could just stick the edge of the phone into the grip???

Clever and useful.

There is an iphone app that uses the camera in conjunction with an alignment intersection on the screen to view the tip of the main blade. Simply center the line on the leading edge and trailing edge of the blade while viewing it through the camera and read the output. Always in your pocket, nothing else needed. May not be super accurate, but definitely a ballpark tool.

That is very nifty, but how do you make a call with that phone if you have to?

The iphone works great as a pitch guage.

I will not buy a digital guage as long as my smartphone works

I built a similar setup using the clampy part of a pitch gauge and a lightweight piece of thin hobby grade plywood meant for rc planes. I clamp the iPhone to it using rubber bands and it doesn't shift because it has an edge to be clamped against. Stick it on the blade just like a regular pitch gauge and it does not move and the weight it pretty neutrally balanced so there won't be movement. Not that the weight could overpower the servos anyway. The app I use zeros out so as long as the blade pitch is at 0 degrees when you start you zero the app and you measurements are accurate. Doesn't matter if the helicopter is level or not. The app is free and looks like a construction bubble level but also gives the degrees numerically. Works awesome, makes FB and fbl setup a breeze.
