This hotend is really awesome. It preforms very well with a very short melt zone. Without the UHF extension I can get ABS to achieve ~25mm3/s with amazing reactions @ 0.4 with Galileo 2. Same heat up time as Rapido V2.
The UHF extension is where things kinda fall apart. I can get ~32mm3/s but retractions are 0.8mm but still is wispy. It also take a 2 1/2 minutes to reach 260c
This is a great hotend with the extension but the Rapido is much better when the extension is installed.
This hotend is the same exact dimensions as the Pheatus Dragon without the UHF and can use the Dragon StealthBurner Printhead.
When the UHF is install it is same height a the Rapido but does not tapper to the top and cannot use the Rapdio Printhead.
This is a link to a modified Rapdio printhead which will support the UHF extension.

I will be running with a CHT and not the UHF because I get better retractions and good enough volume for my printer.
I really like it just wish it was easier to find the information for it. It will not be on Phaetus's website but directly on Drop Effect's website.
