RE: Which ultimate?
I also have the DP Ultimate with a Saito 72. It is an awesome plane. It flies smooth and predictable. Take offs and landings are easy and can fairly be slow if you want. This plane will do anything I ask of it. Actually it will do more than I can. I have even gotten it to hover, and this was the first plane I have ever tried that with.
I compared the Global kit to DPM's before my purchase and was not impressed with the Global kit. It is not as good, not even close. In fact the Global plane looks like my old Hobbico Ultimate which was a nice plane 15 years ago, it had lots of plastic, but compared to DPM's it was a joke. If you get the DPM you will not be dissatisfied with it.
DP has some issues occassionally with customer service that have been reported here on RCU, but I have not experienced them myself. My dealings with DPM were fine and the products are great. Everyone agrees DPM's planes are terrific.
