The IRCHA Jamboree is the place to be if you love RC helicopters, and rotor-craft of all types and sizes were in abundance at this year’s event. One standout is this 40-pound monster, the handiwork of Joel Rosenzweig from Marlborough, NH. His IRCHA Scale winning Erickson Air Crane S64F weighs in at 40 pounds, has a 6 blade rotor head and 4 blade tail rotor, and uses four 5S 5,000mAh battery packs which gives it a 9-minute flight time at 950 main rotor rpm. This looks more scale than the full size version! (For more IRCHA news and photos, click here!)
What a beautiful machine, must be s real joy to fly .

An excellent scale reproduction. Enjoy flying it.

He is using standard 600 mm blades – but 3 of them for better performance. Therefore, for the TT E720 I would try 3 – 700 blades – but the lightest ones you can find. Keep up the rotorspeed prior to liftoff, and during flight, and I would think they should work well. Let us know how you make out.
where could i find one like that i like Erickson air Crane S64F our can you buy them in remote control
At one time I made main rotor and tail rotor parts for these in real life. I laser cut then remachined the ribs for Erickson air crane . Now I want to find one in an RC and paint it in my company colors. Where can I find one? I retired and closed my shop. Please email me at cavalino328@yahoo.com
Thanks
