Mirocopter SCH-2A Coaxial Ultralight Helicopter

[coaxman]

This is my latest flight in my Mirocopter SCH-2A. I am just a beginner getting to know it better.

Are you teaching yourself to fly your helicopter?

 

[coaxman]

I built my own helicopter simulator rig (see enclosed picture) and spent about 40 hours flying an R22 model in X-plane. Because of that experience I was able to hover in my first lesson of dual instruction in an R22. After just over 5 hours of dual instruction I felt confident enough to take off in my Mirocopter. Here is my first hover:

My second hover was MUCH better than my first:

I went to both US dealers websites but I could not find any prices. Can you let me know what to expect price wise and shipping.

 

[coaxman]

Here is the purchase price and other information on my website: https://rototrek.com/purchase/

Price $37,500 plus around $4K for shipping.

Right now the lead time is 2 months plus 2-3 weeks for shipping.

I'm curious about that metal framework in your sim setup. It looks like something designed for prototyping. What is it?

Very nice Mark. Do you find the SCH-2A easier to fly / hover than the Robbie?

You look to be doing well, but you may benefit from resting your arm on your leg and just fly the cyclic with wrist movements only gripping the cyclic with two first fingers and thumb.
That will help make you smooth .

Hi Wayne. Yes, I do find it easier to fly than the R22. Seeing if it was easier to fly than a conventional tail-rotor configuration was one of the reasons why I wanted to fly the Mirocopter. The cyclic was not as sensitive as the R22 and of course you don't need to think about the pedals nearly as much as in the R22. Not having to think about pedal input everytime you pull collective or transition to forward flight makes it much easier to fly.

Thank you Wolfy for your advice. I will try and consciously work on that next time.

I used these youtube videos to build my helicopter rig:

Because these videos show how to make a standard airplane throttle, I used some of the techniques shown in these videos to create my collective with throttle.

Are the rudders effective in hover, or does this design also use braking on one rotor or the other for yaw control?

The tail vanes are hinged at a 45 degree angle so the are effective in both hover (using the downwash) and in forward flight (using the forward wind). It does not have any braking or differential pitch for yaw control.

 

[wolfy]

Have you had a chance to do any cross wind hovering yet, is there enough yaw authority to do so?

I have and my helicopter pilot friend has hovered my Mirocopter in about 8-10 knot winds and have tried cross-wind hovering. You do not have as much yaw authority as a helicopter with a tail rotor so it is more difficult to hover with a 90 degree crosswind because the tail vanes cause the Mirocopter to weathervane. My friend was able to hover at about a 45 degree angle from the wind direction comfortably.

 

[wolfy]

Thanks for the reply mate, maybe a little less yaw authority than would be desired.

Thanks for the thread about your fascinating little helo, and good luck with it. Since you're still new, you may want to consider dressing with more protection than shorts and tennis shoes. A Nomex flying suit/gloves with boots seems more proper attire. Glad that you're at least wearing a helmet. Keep us posted on your progress!
