Joel, words can not express you how cool that is!!!! Excellent work my friend, now I want one!

Edit:
How much throttle percentage were you using for hover? Did you happen to get any measurements for hover wattage? Just curious ...

Hi Joel, happy to share ideas. I saw your work with the single sail winch servo but decided to use gearmotors so that I could come up with my own solution instead of replicating yours. Plus they can provide yaw control without the need for another servo, so I have 3 bearing joints instead of 4.

Biggest issue I'm having at the moment is getting enough authority from the roll posts. I suspect you've run into this too. I really want to make it work with bleed from the main fan rather than adding separate fans. Perhaps we can discus via PM or in another thread.

hi i use a 90mm and a 80mm edf. current while hovering is about 60amps. taking off vertical about 90 amps. i use 6s 5000mah from apl. throttle percentage is about 55% so i have enough for the whole jet hover time about 3 minutes

i have the same problem but the solution is to make smooth cornering and smooth valves. but perhaps we can start a seperata thread to share information. my roll are strong enought to keep the jet stable. but it is weak for heavy wind. i can do a nice hover under normal flyingconditions. i dont like to use seperate edfs. dead weight when normal flying.

Vtol x35 hover in livingroom (1 min 14 sec)


this was a test with a f22. the f35 is still in progress:P. the one who is flying is a buddy in this f35 project. i learned him how to hover. my goal is to make the f35 as easy as an drone. i used the pixhawk combined whit the kk2.1. (sorry for my bad english :P i'm from holland)

I've been flying electric RC since 1993. Back then we used NiCd batteries (heavy) and brushed motors (bad eff.) for power. Something like this would be a dream way back then and few tried it. Amazing to see these finally work, Keep up the inspiration !
