This is incredible… what’s even more incredible is you did this basically all by yourself! Have you thought about maybe with some more publicity you could get more help/funding? 
 

 

I look forward to videos and fly sight data!

Thank you.

Actually I preferred to do everything myself, it was more difficult but also more rewarding.

So far I made several successful flights, and they are getting better and better. Once I will feel they are good enough I will publish video and flysight. Presently I'm aiming to 8 minutes flight.

Results so far ...   6L of fuel consumed. I'm still learning how to fly it efficiently

I don't know about funding but there are many talented people in Israel who would come at problems with new perspectives. Engineering trained skydivers in particular.

Congratulations on pulling this off!

May I ask what's the biggest challenge in maintaining constant horizontal speed? Did you have thrusters "On" at constant RPM all the time or was it impulse acceleration?

During the entire flight RPM was 97,000 which is turbines' maximum.
As you can see in Flysigh recording horizontal speed was not constant. This because I was experimenting with body position. When I increased pitch (i.e. tried to “fly up”) I lost some of horizontal speed but managed to achieve level flight and even climb up a little bit.
My conclusion after experiments is, that with engines thrust, the optimal flight characteristics are different than in the case of regular wingsuit. Optimal flight speed with ATC wingsuit is around 150 Km/h. But with engines I found that optimal speed is around 110 Km/h, in body position aiming to “fly up”.
I’m planning to experiment more in future. But prior to further flights I have to make significant changes in some of system components, which will take time.
Sadly saying Israel went through horrifying event 10 days ago, which drew us into an unexpected war. So currently we have completely different priorities.

I hope everything goes well for you, family, friends and Israel.

One of my friends, pilot who took me up for jet test jumps, was killed in terrorists attack 10 days ago. He is one of 1300 civilians which were murdered in one morning

Please extend my condolences to his family.

Thank you for sharing your project (which is really cool), and I'm sorry for your pain.
