Thanks BladStrikes for the awesome videos, that was very helpful! I'm amazed at the difference between the 91hz and the 91sr 3ds!
By the way I'm loving that 550 I got from you about a year ago!
Remember to keep everything balanced!

couple guys fly those at my club and its insanely awesome. the only thing i've seen is a clutch break from time to time which was fixed in a matter of minutes. i dont know what your doing to strengthen the heli but i know my bros do thiers up solid!!
never seen a jesus bolt break! main gears strip on electrics too..

power to weight... and as far as flight time, bout the same as an electric flight only added smoke
I did a big block mod on my Raptor 50, 6-7 years ago.
I went from using +-11degrees to +-16degrees with 620 blades.
Yep it was a blast.

The clutch held ok, about 30 flights into the fun I shearded the lower Jesus bolt just before I climbed ballistic for a 600ft auto.

I watched it free fall from 600ft. Not much left after it reached the ground. LOL

I did rebuild it with a modified/ported OS 50. The performance was about the same with way less fuel and no drivetrain issues.
She still flies.

If you want more power, GO ELECTRIC!

No problem man..Yeah,the YS 91SR 3DS is WAY,WAY more powerfull over the OS91 HZ..It doesn't matter what type of flying you do,you'll notice a HUGE difference in power/torque between the two...
Glad you like the heli..Its a beast and loved it,took well care of it..

Not really. Even if you change the gearing which most folks don't do, you end up with 90 size fuel consumption, stripped main gears, broken clutches, and the ultimate, broken Jesus bolts, and a heli falling out of the sky.
If you are able to work all that out, trust me, you'll have an ultimate 3D machine. Ask me how I know.
In any case, "aggressive" is a bit of a broad term. The 600 will be more agile, the 700 will have a higher top speed. Generally speaking.
