RE: OS 70 Ultimate w/pump
Hollywood,
If you look at the date of the early posts in this thread you will see they were made several years ago.
After the OS 70 Ultimate was introduced, Hobbico decided to discontinue selling it because they would not run correctly. They were discontinued for 2 years before Hobbico/Tower started selling them again.
Now that they are trying to sell off the remaining OS 70 Ultimate production, there is a new model out and the OS 70 Surpass II has been discontinued. The Ultimate will be discontinued also as soon as they sell off the inventory.
