  • Handmade
  • Materials: plastic

Please note, these items are handmade and so each COBRA turns out slightly differently, including differences in color. The pictures are for purposes of illustration only.

Cobra RTC is a flute support accessory which is attached to the body of the flute. It is designed for standard flutes only. For alto and wood flutes, please use the RTC-AW.

Cobra RTC consists of a clip, which attaches it to the flute body, and an adjustable thumb rest for the right thumb. Cobra RTC is made of plastic with soft plastic pads so it will not scratch the flute or hurt the hand. The soft plastic pads prevent slipping. There is a metal screw to adjust the thumb rest.

Cobra RTC comes in 3 colors: black, silver, and gold.

Buyer Reviews

4 out of 5 stars

This helps keep my flute from rolling in and takes pressure off my right thumb tendon which was sore to begin with but got worse playing flute. I've only had it for a few days but it seems to be very sturdy and has not slipped. I've adjusted and tightened the height of the thumb rest 4 times and it stays where I put it. You need a very small flat screwdriver to turn the screw to adjust the height. The reason I gave it 4 instead of 5 stars is that it's expensive and for that price I think they should have included a tool that fits the tiny screw. Not everyone will have one that size and if you don't have a good fit you could end up stripping the screw.

Amazing. Went the extra mile and made an alto cobra C. Love the color too! I'd give six stars if I could. :)

I bought it for my Baroque flute and it fits and works wonderfully! I have very short thumbs and wasn't able to balance the flute well, which caused issues with technique. Now I can balance and stabilize the flute much better!
