The goal was a 5'-Copter under 250g because of local restrictions.
I really like the frame designed bei Christian from Druckbär racing frames.
I started with the standard 5' frame. After some issues with touching props I modified the center body with the racing arms and changed the position of the arms to the upper side.
I'm still a beginner in fpv-flying but I really like that frame.
I also tested biblade-props but I prefer triblades even with the higher weight.

performace? speed? also what biblade props did u try? Also props, this looks like one of my fave builds here

I'm flying freestyle, so the maximum speed is not my main focus. The performance is really enough for my flying skills. I find it hard to describe the performance without speedtests or videos.
I tested 5040 Gemfans and KinKongs. I will try Dalprop 5050 Cyclone Biblade and Racekraft 5038 next.
Thanks for the compliments ;-)

Maybe try the TMotor T5143 props?
They're not very durable, but super light, very smooth and extremely fast to spin up!

A couple years ago I built the TransTEC Frog and since then I've been patiently waiting for another TransTEC frame to catch my eye. Fast forward to today and the TransTEC Laser S is that frame. It's a 82g racing frame that features 6mm arms, a TPU micro cam mount, 30.5mm and 20mm stack mounts and 3K carbon and 7075 hardware. My goal here was to build a high quality 6S racer at a reasonable price. I'd..
