Tachometer For Iphone

Andras, does your Acoustic RPM app have an icon that looks like this:



I have that one, but have yet to test it on anything dependable.

Balogh, how did you tape the phone to the wing for the flight? That's cool!

Cool! I thought that is how you did it. I just could not wrap my head around the app "listening" through the phone while the video played on the phone. Did you have to do anything special to port the sound in software to the Tach app? Or was it simply "make sound over speaker," and listen to sound via the microphone?

That is a really cool picture of the .051 cruising along. Very nice. Decent RPM as well.

Thanks

It really revs up going downhill.

I read through a few articles on the Forum. I am definitely Not Tech Savy, and don't have an I Phone for a decent app for a tach. Fine with my Android Samsung Galaxy2. I had picked up an old New in the Box Hobbico Digital Mini Tach for earlier projects. I am now Very interested in a Hand-Held Tachometer, that does not cost an arm and a leg. I have been performing a few modifications to the good old Cox 8cc Production engine. Deck Height, Tank and Backing Plate modifications, glow head testing and so on. The RPM's I am coming up with on the Old Hobbico cannot be right, swinging a 5-2Prop.
Would someone out here in the Forum be kind enough to make some suggestions?

P.s. Please don't recommend building a Tach, I already have too many "Irons In the Fire"
