It's all because in my area - there's no spacious park or bando to fly, hence this frame created.
I've been in love with the JeNo Fit 5" since I built it months ago, so the only thing that make sense to me is to shrink down the 5 inch version into a 3.5 inch.
At first I don't have any expectation since this only for my "side-quest" freestyle rig - But oh boy I was wrong...very wrong...
With the help of members of the WE are FPV community (Jerome & Nochamo) - we've been able to make this frame comes to live.
Even tough this frame is mainly designed by me, but I've always keep it stick to most of the previous JeNo philosophy, Which is:
High performance and durability
Completely clear video feed, with no frame or props in view (3.5" size and under)
Spacious and easy to build
Open source
Huge thanks to Jerome & Nochamo for their feedback, opinion, and sharing the experience. Once again, this shows the benefits of open source, where everyone gets to benefit.
