I built a 2s 3” toothpick with 1202.5 6400kv motors.

A 1.5” toothpick/whoop with 3D printed frame. 802 20000kv

Now I have a set of brand new 1202.5 11500 1s motors and I don’t know what to build with them. Any ideas?

They're are more of a 1S motor.  Good for a 2" - 2.5" inch rig, possibly 3" rig with light props.

Which company? There are three companies that I know of that make those (and probably more I don't)? I have a set of those from RCinPower. They are rated for 2S, but use low to mid pitch props on them. Build size, probably 2" if you are running 2S, then you won't be taxing the hell out of the motors.

On the ones I have, you are looking at a temperature of 75C on GF 65R bi-blades, so i would go down to 2" and see if you can shave some degrees off the temperature (or maybe go up to low pitch tri-blades). So they will apparently be ok with those temperatures, but I would probably be spraying them up with high temp lubricants in between flights and keeping on top of maintenance. I don't think the ones I have, have an overly high failure rate as RCinPower does tend to make pretty good quality motors, but YMMV.

Saying that they do rip hard. The following two YT channels have reviews of 1202.5 11500kv motors including flight footage in both 1S and 2S configs.

The Quad66 videos are a bit better as he also explains how to tune the builds and has good commentary while he flies. But the Tinywhoop channel has many more builds and flights, if you are looking to get an idea of how a certain motor flies. Worth watching both.

Thanks I will check both out. The motors are the happymodel which are rated at 1s only. They are the stock motors on the crux3 ELRS. I don’t really want another toothpick. I was thinking about something like the Geprc phantom or another similar frame.

As long as it's light it should be fine. Maybe the HGLRC Sector25, Armattan Tadpole, BetaFPV HX115 or something similar. But bear in mind on 1S they produce about 360g of thrust in total on GF 65mm props.

I think the HM motors might run 2S (every other 11500kv motor from the other manufacturers does), but I would probably set a 60% motor limit and experiment while increasing it until you find something you like, that doesn't toast the motors.

The GEPRC Phantom is sold as a Toothpick.

How about something like the NanoLR/Rekon3 and the various spin offs inc 3D print variants if you'd like a change?

alot of "toothpicks", it was originaly the name of bob roobis frsmedesign on 65mm blades.
toothpick doesnt truly describe something, it was used for an ultralight frame.

the geprc and tadpole hase both topplates and are able to carry the battery on top. they arent as lightweight as frames with a baseplate and just a lightweight canopy.
if you set the difference to a "toothpick" in the batterymount; i would vote for a tadpole than.

personal i would build a lightweight a 2" or 2.5" on 2s or a 3inch with gemfan 3018×2 on these motors, a sub 60g uaw quad.

If you can find one, I would try the HX115 frame, it's seriously light at 14g (but thin arms) or the Rekon3 for the 18650 holder, which would give you access to 1S 18650 Li-ion, but it's downside is it weighs 23g.

Probably the HX115 is your best bet for a lightweight cruiser that stays in the air a long time. With a 14g frame, you should be able to keep the build weight under 60g, just remember it isn't the strongest frame ever, so try to avoid flying into hard objects.

But the Rekon3 also has the positive of taking an 18650 which definitely would give you some decent flight times.

If it was me I would buy 2-3 frames and try them one by one. Failing that maybe try one of these Twiglet frames. They are pretty solid, don't weigh much and technically aren't a toothpick. They are currently my favourite 2-2.5" frame.

I am in the same boat. I accidentally ordered wrong motors - 1202.5 11500kv, and seller refused to cancel. So I am stuck with more high KV motors than I have FC or frames for.

IMHO this BetaFPV 95mm build I'm working on needs.. nay.. deserves at least 1204.

So I'm waiting for spools of 0.21 0.23 0.25 etc.. winding. After I try (and successfull) rewinding 1404 for a LR 2S 18650 build, i will try to rewind my broken/burned GEPRC 1204 to about 8000KV.

Then I will be able to have nice writeup and review.

Well, they ended up going back into a 1s  3" toothpick.  I got bored this weekend and cobbled together a bunch of spare parts.  Foxeer toothless camera, HM F405 AIO board with all connectors removed, A custom TPU canopy, and an RHCP Can.  All said in done its 42 grams and actually pretty fun to fly.  

looks nice!



it might be benefical for many reasons to mount that big active element of the antenna directly on top without passive part between - durability, infield vibrations and movement.

Thanks, There is supposed to be a zip tie up there holding it in further down but I forgot to put it on
