The I can get altimeter watches like the one I use in my plane for $98 (used to cost $145, but I can get a better price now). They weigh 1oz without band and record rate, max altitude, etc. You can even tape them on the wing CG of a H/L and check your launch height. http://store.yahoo.com/outbackgear/freesalwat.html Tom "James V.
