DIY Altimeter for small Rc planes
you can buy altimeters for your Rc planes but their $50+ and i want to know if theres any way i can make an altimeter made from stuff available at radioshack theses planes are light 10-20oz with a 20-40 inch wing span. So i need to know if it is possible to make a small light one for cheep. And if i can then if some body could show me a diagram of how that would be great.
Thanks for the help.
i just need it to record the maximum altitude reached
