I have no experience with a Dream Classic but do have first-hand knowledge of similar aircraft and Airdrome Aeroplanes.
I presently fly an Airdrome Fokker D.VII which I built from their kit. The kit is primarily a materials kit but is well-supported by Robert Baslee the designer and owner of the company. Construction is simple and easy to accomplish with basic tools. A call to Robert will provide a ton of details about the aircraft and its construction, he is very willing to share information.
I also built and flew a Legal Eagle whose flying characteristics should be similar to the Dream. Any Part 103 aircraft is going to feel like flying a feather compared to heavier aircraft. These aircraft are best suited to calm air, turbulence is more work than it is worth. I suspect control characteristics will be similar to the Eagle and D.VII which have adequate aileron authority, good pitch stability and good harmony....if you know what the rudders pedals are for. In other words....flies like a very light aircraft.
The biggest decision with the Dream will be deciding which engine to use, choices are very limited if you wish to stay within Part 103. Do your homework, and best wishes for an enjoyable project!
