I plugged your info into Castle Link. A 500kV motor, 13T pinion, 112T main gear and 6S battery will only allow for governed headspeeds between 850 and 1100 RPM -- too slow for your AH-6. As Don mentioned above, you're going to want between 1400 and 1600 RPM.

So. In my opinion, you have 2 choices. If you're going to fly on a single 6S battery, you will need a higher kV motor with that gearing in order to get a workable headspeed (between 1400 and 1600). An 890kV motor would work with that pinion and main gear on 6S.

Or...

You can get an HV ESC that supports more than 6S and run a 10S setup (2 x 5S batteries) with your current 500kV motor, 13T pinion and 112T main gear.

My AH-6 flies on 2 x 5S 5000mah batteries (10S) with a Castle HV80 ESC, 550kV motor, 12T pinion and KDE 115T main gear. I have governed headspeeds of 1400, 1450 and 1500.

Hope this helps.

No chance i can use a series of battery. no room. maybe get the 890kv. 1600 rpm for flying?

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.
Don
Don, yes its correct. now its clear that my rpm is too slow. i will get a higher kV motor to get the 1600 rpm. i can't imagine how fast is that 1600. hope my fuselage can handle it. lol.

Ok, found a 1220KV motor. if i have 13T pinion and 112T main and a 1220KV motor at 50% throttle i will have at least 1600rpm. is it right?

Thank you for all the help Gentlemen.

Jason.

The 1220kv motor is way too fast. With the gearing you have now, a 1000kv motor, governed at 92.5% will give you a good top rpm of 1650 and from there you can tune it down as you get more comfortable with it. Don't jump at the first thing that crosses your path, thinking it will work, as you will waste more money and time. It is a very sharp looking Little Bird. Have fun at HSM.

Set him up a flat throttle curve (set rpm in gov mode) at HSM and the thing flies great, even in the wind @ 1170 hs. No weight and 4blade tail makes it work even with the 510 motor in 6s!!

Jim set the Governor mode at the HSM event. right now my set up is 510 kv motor, 13T pinion and 112T main gear. with 1170 HS. flies even better now.

Helicopter Scale Masters 2017 Report

On August 24th-26th, 2017 we had our seventh International Helicopter Scale Masters event. What a BLAST we had! This year we had overseas participants coming from Germany and Chile. From the States we had registered pilots coming from Oregon, Nevada, Washington, Arizona, Louisiana and California. We had 21 registered pilots. The weather was HOT as hell and the action at the flight line was non- stop despite the heat. This year we had some amazing scale helicopters at the event. Several of them, turbine powered and some incredible electrics too. One specific helicopter was awarded several times. This model belongs to my good friend Daniel Lowry. Daniel brought to us his new Vario CH47 Chinook tandem rotors, simply amazing! The scale details and the flying of the Chinook was superb!

We also had several full size helicopters coming and landing at our field. I brought as a pilot in command on August 24th a Robinson R22 with my copilot Romano who came from Chile for the event. We flew from Santa Rosa (KSTS) direct to WDA field flying over Lake Berryessa. On August 25th I also flew in a Robinson R44 with Romano to our field. Once we arrived to the field we gave rides to many of our good friends, total blast! At the end of the day I had a vapor lock on the R44 during the extreme heat at the field preventing my departure schedule at 5:00pm, so I was literally stuck. I call my friends at Helico Sonoma and in about 30 minutes a Robinson R66 turbine arrived to the field to assist us. Alec who is our instructor and AMP assist us to get running the R44. Thank you so much Alec and Steven the owner of the beautiful R66. At about 7:00pm the R44 and R66 helicopters in route back in formation to Santa Rosa. What an amazing day and adventure!

On Saturday August 26th we had the Robinson R66 and R44 helicopters coming to the field information as well as the legendary Huey UH-1C from our friends and brothers at Hueyvets. The legendary Huey UH-1C from the EMU 309 Vietnam unit fully restored as when it was flying in their unit during the Vietnam War. The Huey also performed some low passes that got all of us inspired for the next project. This is the six year we had support for the EMU 309 group at HSM and I have say the owner, pilots and crews are the nicest people. The Huey is based in Hayward so it took about over an hour of flight time to come to our field.

We had some amazing prizes that were given at our event for some of the awards.

Helicopter Scale Masters 2017 Awards:

Best Fire/Rescue Helicopter Flight Demonstration: Tyler Grey
Best Military Flight Demonstration: Gonzalo Martinez
Best Paint Markings: Jim Davey
Engineering Excellence: Karl Hewlett
Best Scale Flight: Thanh Cung
People’s Choice: Daniel Lowry
Al Wert Excellence: Rick Jow
Best of Show: Daniel Lowry

Outstanding Support: Helico Sonoma

I want to say thank you to all our sponsors for the event with their generous donations of resources and for the top prizes. We had the following sponsors this year: Vario Helicopters Germany, RC Aerodyne, Starwood Models, Graupner USA, HueyVets, and Helico Sonoma.

I also want to say thank you to all the pilots attending HSM! I was so pleased to see some new and fantastic participants coming this year! We have forged some incredible friendships and more to come.

I also want to extend my warmest thank you to our club, Woodland/Davis Aeromodelers! And to all the fantastic support from our volunteers! All logistics performed spectacularly and the dinner on Saturday was superb! Without your volunteer support this event would be impossible to run. Thank you so much!

We are still finalizing the numbers we got from the event. I am so thrilled that we already surpassed $4,500 on corporate and personal donations. All donations were given to Autism Speaks charity. Since I started HSM in 2011 we already given to Autism Speaks close to $80,000.

Warm regards and Thank YOU,

Gonzalo

It was a great turnout and a great event. The best part is seeing good friends as well as meeting pilots that are new to the event. I would like to give a big thanks to Gonzalo for hosting the event and for bringing in the full size helis for us to see. Also to Mike and the Woodland Aeromodelers for opening the field up to us and providing food and drinks to help keep us fed and hydrated over the hot weekend.

Very special thanks to Kirsten from Vario for supporting the event and for the Al Wert Award which is very special to me now that I am flying Al's Starwood Lama with him in the back seat. Hopefully Gonzalo will recover from the weekend and will be willing to do it again next year. Thanks to everyone who made it possible.

Regards,
Rick
