I decide to desing something small so I made quad 250size.
This is similar thing to spanky frame ,but with interchangable arms,available as spares.

Frame weight is 230gr as on pictures.There are simple nuts somewhere - but will provide self clinching nuts all over quad frame - save weight.
Just don't have enough for first build.
Also can change arms easily after crash or crazy FPV

- every part of frame is available.
Funky quad is made from G10 material 3mm bottom plate with 3mm arms ,top plates are 2mm thick.
Zenmuse dampening system build in ,takes all vibes away and keep weight down.
From cage for 1/3 CCD FPV cameras.

Anyone interested - post here ,comments ,mods ,ideas everything welcome.

Looks good Marcin! However if I may help you to improve the design with some constructive criticism. Firstly its a little portly my spanky weighs a good 55grams less. My other comment would be the isolation dampners, those style could pull apart in a crash, might be better with the original QAV/Spanky style ones. If you could loose some weight and change those bobbins I'm sure you will be onto a winner

bottom plate can be done in 2mm G10 - this is smaller piece = less weight + still waiting for these selflocking nuts.
Separate arms add weight unfortunately there have to be more parts ,but these arms are 3mm thick and 3cm wide ,where planes you send me are 2cm wide so can make them less wide ,this will drop weight a bit.

I can assure you these zenmuse dampers will hold a lot ! 12 of them hold's my whole 3 legs with 3axis gimbal and weight on them is 2.2kg.They are different dampers then these from HK - got them all here and stifness is a lot better.
Bottom plate is done in 3mm as I said ..but there is no holes in bottom plate at all - so making couple + 2mm G10 will drop weight ..I will definitely improve all these details with time and ,promise weight will be same or less then spunky

...I hope.
These plastic bolts are jjst standoffs ,so changing them to plastic standoffs with tread inside might drop weight also - for now I have to use 45mm long M3 screws

Thanks for ideas and comment Ben.
