First Look at the OS 50 Hyper.
I went to a fun fly this past weekend in Albany GA. Met some of the guys from on-line and had a great time. The one thing that really impressed me was how well the OS50 Hyper was doing. They were doing some pretty heavy duty 3D and the motor wasn’t bogging at all. Lanny Baker told me that running this motor with a Muscle Pipe II was a dream. Tuning was extremely simple compared to his old OS50.
I spent some time trying to get my TT50 Pro to run with a Muscle Pipe II, I thought we had it figured out by using a regulator and check valve, but when I got home it ran like crap again. Thanks for all the help guys but it didnt work! Looks Like Hyper Time !!!
My new OS50 Hyper came in yesterday, and I figured I would wait until I do my CCPM conversion on my Raptor. Well that little Blue Headed Devil kept calling my name so this morning I plugged it in to my Raptor.
Installation was pretty simple, I used the OS motor mount that came with my Raptor and it bolted right in. I had one problem with the Carbon frame stiffener hitting the head. I shaved it down with a dremel and it fit perfectly. The head looks like it will dissipate the heat much better than the old square types and you also get the cool blue bling factor as well.
The instruction manual stated that for break in run it slightly rich for the first few flights. Yahoo that’s a whole lot better than 5 or 6 tanks getting light on the skids.
I turned the main out 2 turns and left the slow speed where it was, cranked it up and did some hovering around the front yard, it was pumping out the smoke but sounded pretty good. I use a GV1 for my head speed and its set at 1800 in normal. I am also running 30% CoolPower heli fuel. I set it down after the fuel level hit the header tank and felt the back plate, it almost felt cool compared to my other motor.
I decided to hover one more tank full before I started pushing the motor to see how it feels. Well after 10 or 15 seconds it died, I refired it and it died again, the back plate was still real cool. Can you say GLOWPLUG, the OS8 that came with it was DRT better known as Dead Right There. Changed it out and back running like a dream.

I leaned the motor up a few clicks and went to IDL1 to see how it liked 1875 for a head speed. No problems, sounded great and was real responsive. Next I did a punch out from the ground, Man this thing has almost twice the climb out of my TT50.
I think the combination of 30%, MPII, and the OS50 Hyper is one that cant be beat!
I heard some rumors about bearings being the same as the old 50, but I think heat is what was killing the old 50’s as they didn’t really have a good carb on them. This thing really runs cool, and has Gobs of power, the 60L carb has a massive 10mm throat on it. Fuel economy is not a strong point, I lost about 3 minutes on a tank at hover so I’m guessing a little more in forward flight and even more in 3D mode.
I’ll keep everyone posted on the progress this motor makes, and I have a couple of more reviews to do over the next couple of weeks so stay tuned for more great info (at least I hope its great).
Thanks for reading
