Chip Hydes "Milt's Aerobatic's is fairly good and probably worth the $30.00. It is laughable that the producer chose to have a picture in picture of Chip's transmitter while he does his magic as he had the most nervous, switchy hands on the sticks. They are impossible to follow. But Chip's narrative as he is flying does describe what he is doing. He covers a lot of the basic aerobatic maneuvers and even shows some "bad" execution of some. I periodically watch it and then go to the computer simulator to practice.

The "Wring It Out" series (3 tapes) by Dave Patrick is probably a better buy. The picture in a picture of his hands on his transmitter is good. SOme of the same manuevers are done by different types of planes such as the Ultimate Bipe and the Extra 300. I have tapes II and III, chosing to skip I as being too basic.

Both tapes have filler which is of no real value to give you your hour's worth of viewing.

If you have a computer running Real Flight G2 you can download videos of submitters doing IMAC routines. Once downloaded you can select the picture of the transmitter with the sticks moving along with the aircraft. Quite a nice feature.
