oh, nice question...I go through a whole process when I sand. I used to just paint the slick carbon, but now I start with 150 grit paper and then slowly work my way up in steps of first 50, and then 100 to eventually end with these little sanding sponges I ordered from AliExpress. They work pretty good. I also sand if I get any runs or spots I don't like, and I noticed you can create some cool effects if you work in layers and then sand again. You can create these fades and also a worm look, usually exposing the edges first

But yeah, I do sand quite a bit these days. Always start rough and finish smooth. I got these patterns and I don't use a lot of pressure with the right grits

*worn look
....typo

*rough grit, lower pressure
...typo again 🙄

Thank you. I'll try that out and see what happens.
I've got an old BOTAFX I didn't sand enough and after a few impacts the paint chips off.

oh cool, that's actually a frame I've also been trying to find. I emailed the guys from BQE (no luck) and recently picked up a Bandolero. They also sold me some BotAFX top plates that fit my Bot5 frames, which is a life saver for those quads. I also posted all three of those here. You can find them if you look through my other builds...they are all painted...I know it's a bit nuts 😂

I dont't use my botafx. Do you want do buy it (location Germany near Mainz)?

Bofatfx, sprayed in blue, 1 additional arm (unpainted).
Cammounts (21mm), SMA Antenna mount and Immortal-T mount in Emerald Green included.

Thanks! I'm still tuning in, it's almost there but I have some werid mid throttle oscillations that need more fine tuning. I do like the smooth feel of this motor. But tbh I also run the BH Avenger V2 and they're quite nice as well. I actually prefer the BH Avenger because it comes with longer wires.

Hey there, wondering if you've updated this to BF4.5.1 and if you'd mind sharing the tune? Would really appreciate the help

Hello, sure, I can add that. When I'm back from vacation, I'll add a new experience report because I'll now upgrade to 6S.

Hi, I have created a guide. I hope it helps you

Thank you so much. I'll try this mod and will let you know

Cool - danke dir, freut mich, wenn ich eine Inspiration sein kann. Mir ist es wichtig, wirklich Referenzen zu haben. Diese Seite hier gibt einem, einen guten Überblick, über die verbauten Komponenten.
Aber leider ist nicht oft alles dokumentiert oder nachvollziehbar wie effizient oder welche Komponenten welche Leistung bringen.
Und reine Hover Zeiten als Flugzeit zu verkaufen ist Marketing, aber kein Spass.

Frame, Motoren und Stack habe ich nun mal die gleichen bestellt.
receiver wird Crossfire sein.
hoffe dass dies nicht wieder rausgeschmissenes Geld wird wie bei meinem 6" build :-P

Naja, vieles ist auch eine Evolution, die man von Build zu Build durch läuft. Hätte heute meine Flywoo LR4 in den Alpen versenkt, das wäre dann abgestürzt Geld :P .
Schau, dass dein GPS nicht allzu groß und allzu schwer ist. Ich habe meine Verbrauchs und Flugzeit Angaben sehr genau gemacht. Also bei ähnlichem Gewicht bist, sollte alles klappen. Das kleine M100 Mini GPS von HGLRC ist wirklich sehr gut.

Die Halterung für die 18650 Batterien sieht auch noch toll aus. Kann man die einfach so kaufen oder selbst gemacht?
So muss man keine Angst haben, wenn man selbst einen 4S Li-Ion macht, dass man ihn zerstört beim Löten.

Suche einfach nach "18650 Tray" oder "21700 Tray Halter", dann nimmst du 2x 2S und klebst diese ordenlich zusammen und lötest dir die Brücken mit Metallband. Der große Vorteil ist, wenn eine Zelle nicht mehr so frisch ist, kann man diese tauschen. Ich hatte einen MotorDesync und habe so 3 Zellen beschädigt - diese konnten leicht ausgetauscht werden.

It is not upgrade version 2S is exist if look it the frame is different! 2S has fix arm 3S has changable arm!
light version (2S) is better... this type of frame is not very strong better for light version!
this motor with 3inch+3S this config a litle bit better and lighter: https://rotorbuilds.com/build/30167

The only way to find out is to test it. I alway take the C ratings with a grain of salt... meaning it is not always correct. How do you plan to use these packs, slow cruising, or fast free style? You might be okay if you plan to fly it slow and keep the amp draw low. Also keep in mind, I have used higher C rating batteries that has more voltage sag than a lower C rating battery. For example, I have a set of GNB 1100mah 130C 6s that weighs and sags more, less capacity than a GNB 1000mah 100C lipos. So, once again, the only way to find out is to try it out. I personally have not tried that specific lipo before, so I can not approve or disapprove of it. I have tried a few different flavors of the GNB 720mah lipos and they all have been excellent in power and low weight. I typically do not like HV charging my lipos, because it "seems" to degrade my batteries faster.

thanks, that makes sense. I wouldn't want to sacrifice the longevity of the batteries. In this case I'll stick to GNB 660mah LiPO. With a calm flight I'm getting around 6 minutes flight. Curious if stripping the O3 unit would make it much longer. I'm using it also with 5 blade props as it's much quieter but maybe it probably drains the battery more.

can you probide a picture ? i need those 12mm holes lol

I never got proper flight footage after tuning it. These builds desperately need a tune, in fact most 3.5" ultralights do. Spend some time with a step response tool (like I did in the most recent build) and it will be perfectly locked in.

Thanks! I updated the parts list to include the spacers.

Omg, did you use the arm braces? That helps a lot... Or perhaps was your fc that had to much noise.. Whice stack did you use?

i did get the braces. Am using an HGLRC F7 stack. i did get it tuned using tips from UAV Tech. flies well now. if this ESC ever fails i will use the stack you have!

i am also using iflight xing 3106 1500kv motors.

Nice, i havent tuned mine but i Sure will.. Im not Sure if will stick to BF or flash inav for pos hold and better rth... 1500kv what packs are u runing and whats your flight time w those 1500kv?

I run 2600mah and 5200mah. It has been windy here lately so no true tests. However, it is more stable in the wind with the heavier pack and I get about 4 minutes. Not as stable with the lighter pack, but I think I get more time due to the weight. I get about 8 minutes of steady cruising with the lighter pack.

True test will come when the wind does down. I hear it whistling now! (here in Texas, USA). I'll follow up later with my results. I do like the pancake motors, although I think yours are cinelift motors like mine. I used them because I thought it would be a bit more efficient even if not as strong.

today I was able to do a true test of battery and flight time. Finally, no wind! I realize that the 5200 is too heavy. I get seven minutes with it. I get nine minutes with the 2600. But the 2600 is too small. I am going to try maybe a 30 or 40. The sweet spot might be 35. I wish I knew more about lion packs, I’ll bet those last much longer…

Exactly share some video links too to help. Others going thru the same build, i havent been able to Run Real test. Ill try today a 6s 2200mah ill see how it goes

Can you share your PIDS? Getting a lot of wobbles on sharp inputs
