Hey Barry, sorry to see your R22 go down, I'm sure you will get it fixed and flying again.

Would love to see all you guys again at HSM, but life as turned a different direction these days, still flying but only EDF jets. Sold all my scale helis but I did keep two sets of mechanics and parts just in case I get the bug again which may be soon, starting to check in on RR more often and seeing HSM coming soon got me thinking on a project......
If I don't see you guys this yr at HSM, have fun and fly one for me.

Darryl..........

Similar Problem..
lightfighter, I had the same problem on a 4 blade head and tail and changed the tail servo out for a faster one and it cured it to the point where I had to reduce a little travel...
Might help you out..

Jason,
Bring the heli to HSM. There are plenty of good folks there that would be happy to help you get it squared away and flying right. This is the biggest bunch of good guys on the west coast.
Barry

All helis and planes have an expiration date stamped on them...you only find it after you crash!!

What size is the helicopter? What headspeed are you running and how long are your tail blades?

@Co_rotorhead
600 E PRO. I don't do governor mode just flat 50% throttle and 4x 105mm tail blades.

Did you do the auto rotation and front tt gear swap from the 600 nitro?

Ron

I didn't crash. I just ran out of airspeed, altitude, and ideas all at the same time!

Hi lightfighter:

Two things that I found had to be done is to put a motor in that will give a main rotor speed of 1500 to 1600rpm, first and foremost, at your maximum governed speed. You need to go with a governor or you will overheat your ESC dropping it down that much. A motor, somewhere around 450kv with a 10:1 to 12:1 gear ratio, will give you top performance in a scale ship of 600 size. A good example of a good gear setup is the 118t main and an 11t pinion for the Align chassis you have. If yours is the stock 510kv motor, a simple switch of the pinion to a 10t with the 118t main, will give you 1597rpm, which is at the top range but you can still drop it with the governor. Don't balk at the governor, use it as it will save you a lot of trouble in the end. Naturally, if you have a freewheeling ESC like the Kontronik line, ignore references to using a conventional governor.

Second, your tail and main blades must turn counter-clockwise or you will be putting a tremendous amount of thrust against the tail fin, and trust me, there is not enough residual thrust to counter torque. I run my MH-6 and my previous TOW Defender with a two blade tail at 105mm and a five blade head at 600mm. I would go with the recommended conversion to the nitro gears and make sure you move the boom housing forward for proper gear mesh. My 600EFL Pro has been converted so I have the 4.5:1 tail gear ratio. You will be fighting that bird rather than enjoying it. Been there, got the t-shirt. Take care and have fun at HSM.

Barry, sorry to see your R-22 take a dirt nap. Hope it is not much more damaged than it looks.

To the rest that can make it to HSM, have a great time and see you soon.

I'm running the same setup as Don (keygrigger), except my main blades are 550mm. Tail holds well with 2 x 105mm blades. My tail rotor is on the left side of the tail boom (when looking at the helicopter from behind) and spins counter-clockwise as he noted above.

why is my pod and boom flies ok?
Well, you have to remember with the fuselage, cockpit and pilots, weapons, etc. your helicopter is heavier now. This will have an impact on how much main rotor RPM and collective pitch will be required to get the heli airborne.

Are you powering your motor with a single 6S battery?
Which ESC are you using?
What is your gear ratio? (or how many teeth on your main gear and pinion gear?)

lightfighter, if what I read is right, you are 22.2v nominal too low. If I have this correct, you have a 500kv motor, single 6s battery, and the 112t main and 13t pinion. At full throttle, that will only give you 1150rpm!!! If you have it a half throttle in the radio, I can't imagine what you are actually turning in flight. Your motor is half the value it should be for a 6s system. My original power train was an 890kv motor with the pinion and gear I am running now and the motor, battery, and esc overheated running it governed at 92.5%. Are you sure you are running a single 6s battery?

Using a 500kv motor, you should be running a 10s or 12s HV system. It is becoming clear why your tail has little authority and why you can't get the gyro to maintain tail position. If I have this wrong, please correct me. Take care.
