Sure, I would be open to suggestions, please feel free to send pictures or drawings of what you have done, I have tried fly bars, paddles, hinged rotors all without success, your help would be appreciated, pictures would be great. Thanks. Ray K.

I am glad to see a rare fan of rubber-engined scale helicopters! Only a few people in the world do this! I also had experience in trying construction. You can see the Robinson R44 on my channel. Now I have started making a scale of the MI 2 helicopter. With your permission, I want to give you some advice. The downshift from the rubber to the main rotor is an unfortunate decision. The rubber motor likes a lot of torque and doesn't like a lot of speed. Optimal raito 1:1. you Also need to stabilize the rotor, such as flybar, or weights and hinges on the three or more blades. The blades must have a concave profile

Ok, here's what I came up with for a new 90 degree drive, torque and PSI test were successful now to build another Huey to put in in to, original gear box assembly was 5 grams new on is only 3 grams.

Cheers,  Ray k.

Hello everyone, The Huey failed to fly due to the main gear box stripping out, my gear box design is a 50 50 shot, if I get the alignment perfect it works fine, if I am off on my alignment she strips out. This just wont do. I need to come up with something for a 90 degree drive that is not alignment critical. I am tinkering with something new that will not be alignment critical and that can't strip out so time will tell. When I come up with something I will let everyone know.

Cheers, Ray K.

I'm moving this thread to the rubber powered  helicopter category because this is more of a build than a cookup. 

Ray this is a fantastic model, thanks for sharing it with us!

Hello all, she is finished, she even has a nose cannon and all up weight is 54 grams without rubber, less than the VS300,  I will be doing flight tests in the next day or two.

Cheers,  Ray K.
