Speed good, altitude good, sun [:'(]. Sorry about that. Was helping a guy the a while back and lost one to the sun gods. It was struggling to stay in the air due to a poor running engine (OS-LA) and as I was trying to bring it in it got into the sun and since it was already in a marginal flight regime it stalled and went in. My fault in the long run but at least it is fixed now and we flew it again 8 days ago.
