Hi dassault,

The dirty birdy is a classic pattern plane designed to fly with an "old" 60 on a pipe and perform smoth pattern manouvers at high speed. I have one with a modern Irvine 61 and it is probably my most used model at the moment.

I would strongly suggest you follow the advice of a more intermediate type model before progressing to the dirty bird as whilst it will fly slowly and land beautifully when you open the tap things happen very quickly albeit smoothly.

I agree it is a third or fourth type model when you are very confident flying the "point and shoot" variety.

Good Luck,

Colin
