Ran a Typhoon 500 in my DF26 today. Very choppy water but, it seemed to perform similar to the UL-1 motor, only its $25 not $57 or so.

I ran same prop as with the UL-1, a k42mm Graupner carbon. I also tried briefly for giggles, a Grim 40mm x57mm 3 blade and it rocked nice on that, just too much torque roll. The 42mm gave it similar if not the same speed as a UL-1 but, thats just a visual, not backed by real numbers.

I don;t have any water cooling on it and the second and third runs it came back quite nice, not hot at all. The first run with old Lipos it was hot but I could hold my palm on it continously without burn.

Best damn $25 motor I've ever tried. Hands Down!!!

They are in stock for once too.
