old and used parts:


- diatone mamba f4 20x20mm
- diatone mamba 4in1 20a
- akk 20x20mm vtx, dont know the model, has a builtin mic and able to provide 600mw (as space is needed, a nano32 would be nice)
- eos turbo (to change after settup)
- t-motor f20 II 3250kv
- modded baseplate of airblade uav eclair 3“ frame
- fs-a8 ibus receiver (to change, looking for some space)
- 20x20mm canopy, a design found on thingiverse
- rubycon 25v 470uf and a changx 25v 470uf, this combinations as a try, i will remove one after a few flights and an impression
- for the moment some dalprop 4040x3 and 4045x3, i need some hq4043
there are some gemfan 4023x3 on the way.
- crappy lipo strap
- griptape for the lipo

will be used with 650mah 4s, probably 850mah 4s lipos

bf4.2 rc2

wasnt allready on the scale, should be about 100g, hopefully less. a true ultralight, should be my lowest weight 4inch.

It will probably fly with a those different props.

it would somehow xD i wont try it like that

4x dalprop4045 will be my first try

A true four inch Frankenstein, lol... Love it!

You're going to give that FC some serious processing to deal with those props!

its windy, to much. the maiden was a bit shitty.
its fast - nice topend, its okish about efficiency but its not responsive enough.
regardless the wind, the f20 doesnt spin the dal4045 v2 well, the prop is to heavy, to much load. i doesnt own a more lightweight lowload prop at the moment.
some gemfan 4023 are needed and i will order some emax avan 4024, i will try them if they arrive soon enough.

originaly frankenstein should receive new emax rs1306 4000kv, paired with hq4025x2. still waiting for this motors i deceided it need to fly soon, added the f20s. i beleive i will hook the f20 to another build if 1306 arrive.
i mesured 121g, to heavy an 850mah would decrease the crashability to zero. 1306 makes more sense for this settup. the frame is thin and still not stiff enough with the actual uaw.
with the rs1306 the weight should be decreased at least 20g, the motors have less weight and the props aswell.

the gemfan 4023 are very nice, all props should receive the t-mount-5mm shaft ability. work nice without issue. 650mah 4s is perfect,gets very responsive with the low prop pitch and tall blades.
was pleasure to fly gates and around flags indoor and the frame is still alive after a few crashe :-)

the emax avan 4024 and 4028 have longer blades than all my other 4inch props, they touch eachother on this frame. i didnt mesure, but i guess they are smore about 4.2inch - bad declaration from emax... why...
