I found this new Reptile RX155 frame (also available as 130 size) and it looks quite nice. I have been looking for a lightweight and sturdy frame for 4" props, and by the look of it, I would think that this frame gives more protection to the electronics in a crash than my previous Diatone ET160.
Does anyone have any experience with this frame? It also looks like there is one version for small motors and one for small/big motors
