Nitro Nimbus flown by Keith Williams at RCHO! 

Looks like it needs a bit of tweaking….Clutch liner looks a bit tight!

So weird seeying a nimbus with all that nitro smoke. Must smell great!

Great video bill! What went wrong at the end? It sounded pretty bad. 😮

awesome video. thank you so much for sharing. very cool!

I started flying when nitro was the only powerplant and I will never go back. Was so glad when electric matured and I was able to ditch it for good. the vibrations from nitro motors kills things way too quickly. My electric helis last many times longer due to being smooth as butter. Did you see how the skids vibrated violently on takeoff? Lol
