I've just about started taking some shots from my quad using CHDK and a A490. Only had about 4 flights with the camera running. Last flight was to take a few snapshots for the estate agent who's seing our flat (just bought a new house to get a bigger hobby room). I know the shots are not of very good quality, but being a complete novice at taking photos I don't think its to bad a start... I think the A490 looks to be a promising camera even if it is out of date. Camera is mounted on a anti vibration platform that I got from someone in Israel via ebay
, Does wonders..
So the A490 seems to be a very viable option for aerial photos.
