LonR you the man. I 100% agree now after flying the 50 with 90 in it that it is pretty fun and worth the effort if you've got the engine. You happy you win
No,its not about winning anything and im being 100% honest.If that 600N has a OS 70 in it,something is wrong and its what you said below
Just flew that 90 t600 again and its a fun heli. Stock gear ratio with no stripping issues.
You can't run the stock gear ratio because you'll never run in the power band of the motor.If anything,trust me this one time and stick a 22T pinion in it with the stock 170T main gear.Tune the motor and have fun.Not being funny at all but when you roll that heli and did tictocs,it bogged.Change the pinion..

the .90 in the 600 was powerful. Wasn't even in the same class as that logo that threw the battery though

High Voltage just works better

Hey, I just thought of something interesting.
I bet this thread has broken a RR record for how many people that have unsubscribed.

I'm glad they did rather than complain about how boring it is to them.

Oh, and btw, a 22T still isn't enough for the OS70. It redlines at 18000 rpm. Not goint to have a good HS with that.
Anyway, that isn't such a good choice these days anyway. Only 2.5 hp and it weighs the same as my YS91.
Actually, I shouldn't say it's a bad choice. It actually looked to be running pretty strong and efficient. Just not what I'm looking for at the moment is all.

I'm looking for something that'll be able to puke out everything it's got in 4 or 5 minutes....just like an electric.

You have a little to learn I guess ..
OS 70SZ-H specs from TowerHobbies:

Power Output: 2.5HP at 16,000 RPM
Practical RPM Range: 2,000 - 18,000 RPM

16000 RPM is where you wanna run the motor Bob now lets do the math .

170T main gear/22T pinion is a 7.72 gear ratio right?
Now divide 16000 into 7.72,thats a 2072 RPM headspeed.Runs AWESOME at a 2150-2200 RPM headspeed.
I hope you don't blow your YS 91SR ..

Since we where on the subject of Lipos has anyone tried these yet? http://www.hobbyking.com/hobbyking/...idProduct=14960

At $17 for a 40C LIPO with a 6C charge rating I couldn't resist. Total cost for two batteries including 3 Day USPS priority mail shipping was only $40.92.

The new Hobby King USA warehouse really seems to have gotten their act together. I ordered them at 7AM and they where in the mail by 8:30 with USPS showing them as in transit to destination by 10AM.
Wow!! with so many people bashing Chinese LIPOs, I was surprised to see Hobby King sold out of those $17 LIPOs over night!

To late now They sold out in a flash after I posted the first link! Anyhow the deal was $17.77 for a 2.2Ah 40c Lipo with a 6c charge rating.

I ordered 2 packs with 3 day shipping and it came out to $40.92. Great shipping to! I ordered them on Friday and USPS shows them at my local post office which means they will be here Monday morning.

BTW Bob,
You need a 23T pinion for that motor with the 170T main gear.You can run a 2150RPM headspeed.The motor will run right around 15500.

Damn Lon you got some sweet pics in your gallery

Regardless I got you both beat on power. I have a heli with 2 motors One for the main rotor head and one for the tail. Can't wait to finish building it but its nothing custom its a existing product by mincopter. I going to record the power on the tail to give an idea of how much power the tail actually uses.

Too slow man. My electric 600 doesn't come alive until 2300.

That's funny, I did that a number of years ago with a 550 and a 500. Had the motor mounted on the sideframe running the tail belt. I did it for the exact reason. I also was looking at performance at different tail speeds and 2 and 3-bladed. It never flew all that well as for tail control but it gave good data. I can dig up some of my data if you're interested.

Ive already flown this heli a few years ago. I just recently got time to revisit the airframe. I custom wound a motor for it...tested and working great.

My goal is to simplify the tail(using an alternate Minicopter tail mount and a few light weight tail options) and reduce the overall weight. The machine is a utility machine that is a solid reliable platform for things like AP. It's also a beast

Hopefully I finish it this week. Its a flybarless 90 with 2 motors, 3 packs, and 2 ESC's. Just when I was saying things about bobs machine mine takes the cake for electronics required but its pretty cool. When I'm done I'm hopeing to be in the 10.5lb range with crazy power for about 4.5 mins. The way I'm starting to fly that's more than enough time My guess is the tail can use 20-30% of the total power in a std machine(discussed on this fourm before some where).
