I don't know if y'all have noticed but that carb looks like a real pain in the ass to get out of the engine if it is in the heli. It's not always convenient to leave the carb on the engine and then install in the frames.
Don't see much differences with YS 50 ST carb in terms of easyness of removal.

2.1 hp is not much of a change from the Hyper. That is too bad I have a feeling that some will not be happy with this power output. WE really need an engine that is in the 2.5hp range for todays 50 heli.

It's a 10.5% increase in power.

Or in other words, it's like shaving over 3/4 of a pound off of a 7.5 lb helicopter. Not bad.

I disagree with the way you approach it. Eventually, you can't admit tha a 10% power increase will be equal to a 10% weight relief .
Power increase contributes more to the capability of a heli (while being on power), to deal with cyclic inputs without loosing head speed.
IMO the 2.1Hp output, in case it's valid, will be the "Cherry on the top of a cake"

WE really need to improve collective-cyclic management

Not long ago we only had 1.6 hp and back then it was huge improvement over the 46 or 32. Come on, we dont need, we would like to have, that a big difference.

back then I have seen Colin Bell flying a wood bladed TT39 while every one watching believed it was a TT50.

If you need 2.5hp for some work, then you can go electric, have your engine boosted by some boat expert and use a different gear ratio or simply use a 70 engine, that's been done.

Oh by the way, 10% increase in power is a big improvement, Just try to go from 30% fuel back to 15% is see for yourself a 7% difference.

my 2 cents

I agree,10% is a great improvement.(I think) the hyper had an 18% over the non-hyper,And look at the difference,An extra 10% and you have a very powerful engine.Correct me if im wrong on that 18% thing.Everyone complaining now that 10% isnt enough,Will eventually come to their senses and understand.

I wouldn't put too much faith in the published specs. For all we know they're using 60% nitro and testing at -30 deg celcius.

Very true and good point.

I'll just add that the TT Team members that were flying this engine at the LA Fun Fly looked like they had a Turbocharged Raptor 50 tearing up the sky. Those who saw the performance were very impressed - and couldn't wait to get this engine in the lighter Trex 600N!!

Too bad it's taking way too long. I was hoping to get this engine in my Pro #2, but it's now built and flying with a YS50.

"I wouldn't put too much faith in the published specs. For all we know they're using 60% nitro and testing at -30 deg celcius."

I'm sure OS decided to use premium conditions to do their testing also so I think the specs can be safely compared. Both manufactures probably skewed the specs in the "better looking" direction.

I heard the guy who made the OS motors in the past. Is now the guy who is making the tt motors. So the new tt red head should run like a redheaded step child.

There's no way TT is going to release a new premium engine without having better specs than the hyper, even if they couldn't make it more powerful. We'll know soon enough if TT actually flexed some engineering muscle with this engine.

When? As long as it's before next April when I can fly again. Right now it's -21 deg celcius outside and 2 feet of snow.

If you need real power call up Dubb Jett, the BSE 76 is the same mounting as SX50, he can port them for whatever powerband you need, the only question would be if cooling is enough without adding a heatsink on the head. Plus they're a work of powerfull art.

If it's gonna happen it'll happen up there!

Are you saying you can take that you can take a Jett BSE 76 and drop it right in place of a OS50 Hyper without any modifications to the Heli?

I've read that before too, apparently Jett can tune the motor to your specific needs. I don't know all the details (I'm just a guy who plays with em, not builds em), but I'd imagine that they can be tuned to work with the gear ratios we are running. I have a friend who had Jett build an engine for a plane, and he had a bunch of options of how fast he wanted the prop to turn, how he was going to use it etc. I'd assume they'd do the same thing with a heli engine.
