Fricklick Mini

After reading some threads about the very efficient Mavic Mini Motors and finding a cheap source on Aliexpress, i decided to try some builds with them.

This one should give a nice and handy mid-range-time cruiser. Its not build at a total minimum weight, but should be a strong and reliable frame. So far its looking wuite good. first tests seem to be quite promising. Still not sure what will be the final battery for this, so far i tested it from 2S550 over 3S850 to 3S3400LiIon. The Happymodel X1 Board with build-in ELRS and DJI Connector makes it quite simple to wire.

Operation: Broken Arroy - at least thats what its made from ;-)

The 2nd set of motors went into an ultra-light frame build (actually i build this one first, but had both ones planed already) similar to other H-Tube Frames i build years ago. As i had some broken 6mm CFK bow arrows lying around i decided to gibe them a try. Well, the frame is very light and looks strong, but the CFK Tube is extruded and not made from 3k fabric, which allows them to twist along the tube. In combination with the very floppy folding props, this produces a lot of vibration which lets the whole frame shake on certain rpms.

In general the frame design itself looks really promising, so i did a 2nd build with the new 7/6mm woven tube that i just got - weight for is seems to be nearly the same, but it still had oscillations due to torsion on the arms. Last option was to add some 1mm CFK spars on the end of the arms which solved the problem. As they only weight 2.5g for both, i made it to fit the AUW just below 250g.

Ich garantiere bei meinen Bauberichten und Teilelisten keine Vollständigkeit etc...es wird aus den Teilen gebastelt die gerade herumliegen.
Bitte keine Anfragen zum Bau/Fräsen von Frames, Teilen oder sonstigen Aufträgen. Ich betreibe die Seite rein als Hobby und nutze die zur Verfügung stehende Zeit gerne für meine eigenen Projekte.
Bei einigen Projekten werde ich zu gegebener Zeit die Pläne veröffentlichen - aber auch hier lasse ich mich ungern hetzten ;-)

No waranties for completeness of any contructions, part lists etc.. I build from party i have just lying around in my workshop.
Please, No requests to buy frames, builds, etc.. I run this page in my spare-time and as hobby only. Want to keep my free time to work on my own projects - sorry
I will release the plans for some build at some point in time, but again, please don't ask for unreleased plans, i don't want to get rushed ;-)
