11/21/20: i have now reduced the weight from 47grams to 39grams, from 2s 650mah to 2s 450mah, raising camera angle from 35 degree to 45 degree. it should feel a lot more power.

11/19/20: my thought on the motors. the 8888kv is too high. it's ok with 2.5in bi-blade props. but tri-blade props would suck a lot of amp.
I think 7500kv should be good. you should clip ( not scale ) the throttle at 80%.

it is for small spaces it has good control. racing around in a tight place and pretend to be a racer LOL

some people might still remember the original Toothpick 2s 1103 65mm props. this one is the same but with better low end control.

47gram dry + 31gram 2s 650mah = 78gram AUW.
you could use 2s 450mah instead.
Important: If you're not going to use prop screws then use countersink bit ( in the picture and i bought it from CNCmadness. a very useful tool ) and drill at the base of the props, so that props can sit on motors without gaps.

note: i'm just a few packs in. i'm still trying to get used to it.

PID tune is good with this one. it's pretty easy to tune.
betaflight 4.2.4 with RPM filters
use UAV Tech's preset (toothpick): https://theuavtech.com/presets/
and then use PID in the picture.

Just practicing, learning to fly better.

Would the 6666kv with 2.5''props work at 2s?

matthew saigon   27 days ago 

i've been wanting to build it. it would be slow for most people liking, but i don't want to fly fast anymore. and i think it would be great for me. i think i'm going to build it to see what it really feels like.
here is the list i'm thinking of
2.5mm 2.5" frame
happymodel 10a esc aio whoop board with built-in Frysky receiver
caddx lite nano
tbs pro32 nano vtx
Apex 1202.6 6666kv ( 2s )
those new gemfan 2.5" props or new HQ 2.5" props

it might be good for racing in very small spaces.

the motors i really want for 2.5" props are 1203 but still nobody makes them.

Let us know when you finish :)

How do you think those motors would work on 3"?

matthew saigon   Dec 03, 2020 

they work great with 3" props. just need to keep it light.. but i don't recommend 8888kv, it's too high.

Do you think the Apex 1202.6 6666KV would work better on 2S 3"? Or would that be too little KV?

2s 6666kv 3" is fine. if you're flying 3s 1105/1204/1303 3" props and you think it's too much for your flying area, then 2s 1202.X 3" props is good.

Having built and flown pretty agressively for the last 5 years, the proportions on this lil guy look SO good

yeah it flies pretty good. i need to try more 2.5" props to see which one i like most. the new gemfan 2512 props look nice.
and if you have a space for 3" props, it should do good too. give up some control but gain in cruising speed.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
