We've had a successful flight to ~76k' with a combination of TeleMega and EasyMega for primary and backup, respectively. I know of at least one successful flight to well over 100k' that also used *Mega boards in some capacity. The Kalman filter model seems to work quite well.
If you're doing 2-stage, there are definitely some programming tips that I think could really help, particularly around the ignition event configuration and lock-outs. (Sadly, we've had a few flights where the lock-out programming became all too relevant.) I can dig up my notes if that would be of use. Other than that, I think it's fair to summarize the prevailing wisdom as: - Make sure you're using the latest firmware, or at least understand the errata for whatever version you choose to run. - Make sure the accelerometer is reasonably calibrated. - But as long as you're over 100k', it turns out that perfectly detecting and ejecting at apogee probably isn't all that critical. You just need to get the airframe in a good configuration before the atmosphere becomes relevant.
