VTOL rc airplane called the Vertigo

[machiningfool]

I wanted to challenge my building ability for rc aircraft. I was a member of a club here in Seffner Fl. and I had been flying since I was 26, I am 70 now. I fly helicopters and fixed wing, both models and the full scale, so I decided to scratchbuild the Vertigo. You can still get the plans from Airplane News. The original design was created by Grumman aircraft when they were experimenting with VTOL's. One of the engineers got permission to make available to the public this design, one of several that they had built and flown. What a challenge, took me six months to build, twice. So, after a year I flew the model as designed, as I made the mistake of redesigning it to suit my desires, bad idea. After building for six months, had to re-build it correctly as per the plans. It flew flawlessly after that. The motor is an OS Max ducted fan motor capable of 26,000 rpm with a ducted fan, but only turned 18,000 with a 10 inch prop. It weighed 10 lbs. Here in the video was the first hover attempt, I hovered it 15 times after that, never transferred to horizontal flight yet, maybe some day. You might want to skip to about 9.5 minutes, it was cold that day and I had problems getting it warmed up. Robert Brown. What are the odds, Jaffrey Stevenson was in my club and I didn't know that he had built one until one day he showed up with his Vertigo, I will attempt to add one of his videos of his going from hover to horizontal and then back to hover.
