5/24/2020:
so i've tried motor output limit. it's a good thing to learn, so you know how to do it the next time you need it.
output limit at 70%. it seems easy to do. just a few CLI commands.
profile 0
set auto_profile_cell_count = 2
set motor_output_limit = 70
save
so, no throttle limit now.
( in the picture, i put up PID for it with gf3016 props. PID is ok, still need more work )
scale down the throttle feels different from motor output limit. i guess you can try both, one at a time, and see.
I've learned from this youtube video: " 4S motors on 6S and 4S with Betaflight motor output limit and auto profile cell count "

5/23/2020: i'm going to try " motor output limit " tomorrow. i've never tried it. first time for everything right ? hehehe
---my thought on Original Toothpick, 1202.5 + 65mm props ( specifically HQ T65mm ), is going to be the future for that setup. unless there's something more to it that i don't see. 1202.5 + 65mm props will give you faster response. plus they can handle 2.5" and 3" props better than 1103. so, more options for the same motors and weight. basically, you can just swap out 1103 for 1202.5 and you're done ( with appropriate KV, of course )
0----------------------------------------------------------------

it's 1s babytooth's motors. but i use 2s on those motors.
the Bob Roogie's 1s babytooth setup is great. i eventually will move this setup to that.
this setup is more for those who have 1s babytooth setup but didn't like it and want more speed.
it's fast even at 70% scaled down, you can raise the percentage up if you want. it will run faster but drain the batteries faster too.
the speed is about 3s 1303 gf3016, but this will come at a price (shorter flight time. ) the setup feels more floaty.
1202.5 motors are more efficient and better than 1103 when spinning tri-blade 2.5in/3in props. i think but not sure.

weight: 40g dry
frame: 2mm babytooth frame.
esc/fc:: crazybee V3 10a board with built-in FrSky. or any 12a board and receiver ( just try to keep everything light )
propellers: gemfan 3016 or gemfan 3018
motors: FPVcycle 1202.5 11500kv
camera/vtx: mobula7 aio camera ( not good on cloudy day, low light condition ) there are better but light cameras.
batteries: 2s 450mah

PID is in the picture. it's good but not perfect. try to keep the weight around 40 grams if you want to use that PID.
throttle idle: at 4% or it'll take a while to come down.

note: my yard is too small to fly this and it's next to main street, so it's hard for me to fly. i will upload more videos when the weather is nice.

Note: this video is with motor output limit at 70%.

How hot do the motors get? And would you recommend this setup for someone else?

i just got these motors 2 days ago. there is still a lot i need to learn about them. like trying out different 3" and 2.5" props, 2" should be good too. you could just treat them like 1103 motors. these motors should do better with tri-blade props than 1103.

sometimes you see people running 1102/1103 with 3" props. so these motors should do fine with 3" props. but you ask about hot motors, my guess is, because of the KV. for high KV motors you should worry about high amp draw more. as you can see in the video i keep the throttle low and only raise the throttle when needed and for a brief moment.

this is 1s KV motors on 2s. it's not ideal. you shouldn't put 2s on 1s motors. but if you already have them and you don't like the 1s setup then why not.

i think it needs 16awg wires for the pigtail ( battery lead ) but i'm not sure until i've tried it.

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..
