As some may know PRA reached out now to 2 colleges senior engineering departments asking for them to create three open source projects.
Two prerotators one using low tech car starter with a 2-speed, ball, transmission, and a lightweight state-of-the-art (expensive) prerotator and a G-impact fuel cut-off switch for this year's projects.

But I've already reached out to them for next year projects and added UCLA asking all the colleges to design another PRA open source project for jump take-off systems using two 18 HP electric motors,
Reached out for help from Dick Degraw and he advised you only need 30 HP and a Robinson rotor head and it should work.

These are going to be even more fun projects with Dick's help, so there is hope for those who want or need jump take-off capability. PRA will buy in volume to reduce the cost to all and hold in inventory for our community all of the open source projects.

How are they going to test the jump take-off system?
We are looking for an experienced volunteer Dave?
Do you have any ideas?

Will ask Dick 1st.

My main man Jake stepped up and called me offering his experience and about a much better rotor head selection that would retrofit current gyroplanes.
He said to just replace the U-Join with a block using a A/W 95 rotor head.

And this project may move forward this year. Another engineering department head from SDSU just emailed me asking if he could have a project too for THIS YEAR!!
He'll be back from vacation in a week and feels left out of other cool projects. So will offer them the jump takeoff when he sends me the department form.
