It appears that BetaFPV made a special version of their 1103 8000 kv motor for their HX115 SE 2s toothpick. I bent a shaft on mine and of course the motors are out of stock everywhere. Does anyone know of a replacement that doesn't need me to cut and paste connectors?
I would consider a replacement like the BetaFPV 1103 8500/11000, or another brand entirely. But I don't know if any of them come with long enough (40mm) wires with connectors and 1.5mm shaft.

Does it have the normal 4 screw mounting pattern? If so there are many similar sized motor options with the same motor plug connectors. Happymodel has a slew 1103 (many kv options) or 1202.5. I've found HM motors more efficient, cheaper (if you buy them from China), but probably no more durable than the Betafpv old motors. Skystars also have some 1103-9000 kv motors, very light, also inexpensive, but not terribly durable either.
If you would consider soldering, T-motor has a s 1103-8000 that might be a better quality option, and RCinpower has a 1202.5-6000 that also works nicely on a a light 3" toothpick cruiser.

Thanks, I'll look into those. Luckily "wiggling" the bent shaft while turning the motor by hand seems to have reseated it. At least it flew today without all that jello. I'll wait and see if they come back in stock soon or try one of your suggestions. If I get them and have to solder then I will. And I'll know to buy spares in the beginning. Even BetaFPV has 1103 8000 Kv motors that are different than the ones on this quad.

I don't know where you are in the world but these appear to be in stock.

Those look really nice, GEP RC is a solid company, looks like the cables are pretty long too. Thanks for the link!

You are welcome.

If I read the specs correctly, the cables are 40mm and have the connectors so no soldering...

betafpv is proprietary shi...

these motors has 4screw layout, bit they are the only ones using m1,4 screws. m2 is standart seems years...
does the frame fit bigger ones or allow drilling?

Yeah, 40mm length, the hole spacing is the same. I saw Betafpv uses smaller screws. It's a CF plate frame and I have numbered and metric drill bits so no problem drilling them out. Really they are perfect, just have to replace all 4.
The HX115SE is a mellow little flyer, quiet as a mouse, 7-8 minute flights, I want to stick with the 8000kv.

I believe they use M1.6 screws, this is the same for the Skystars 1103s. The Skystars mount in M2 holes without issue, and suspect you can probably fit M2 screws into a M1.6 frame without needing to drill.

If you are replacing all the motors and mainly cruise, I would say consider trying the Rcinpower 1202.5-6000kv. Despite their lower kv, they run 3" Gemfan biblades smoothly. Slightly heavier than 1103s and you will need to solder. I have those on the older HX115 frame with Walksnail and its my favorite 2S cruiser setup.

If you cruise/light acro and are going for HM 1202.5, get the 8000kv. They are optimised for 3S, but run fine on 2S and will give you some nice long flights on a 660 or similar Lipo. If it's a 2S only, then the RCinPower 1202.5 11500kv might be more to your liking, but that is going to be more of a freestyle bird, than a cruiser. Lemony posted some videos earlier in the year of 1202.5 11500kv motors in action on 2S. They fly pretty well.

Cool, still researching. But yeah I like the stealthiness and flight times on this quad. I'm not spying on anyone, LOL, but people seem to really like it so I can fly it anywhere and my hobby buddies at the model airplane or heli fields (not quad guys) just ignore it.

I haven't tried the 11500kvs but imagine they are too much for 2S cruising. I have some 11000kv 1103s but that is run on 1S.
6000kv for 3" on 2S sounds like it would be too low, but it actually does very nicely on a light setup. Efficient, agile, decent punchouts, and smooth, but does not handle winds/propwash very well. Even carrying a Walksnail I get around 8 min on a 650 battery. This video was with the 6000kv motors and no video stabilization was applied, although it was slowed down at certain spots to capture some facial expressions.

At the start of summer I did a rather boring flight on a 2S GNB 660 and that lasted a good 8 mins, then I got bored and landed. That was the Flea build, on HM1202.5 8000kv which is not a cruiser or even slightly optimised for long flights. I just ran 2S and didn't push on the throttle a lot, but it's not how I like to fly. You can only fly in circles for so long.

I got to fly a few packs today, 2s 450 packs, along with bunch of my other quads. I don't think anything less than 8000kv would be much fun, honestly. And it could definitely do with more, response is a little spongy if you push it. I think 8000 is a sweet spot, efficiency wise, it's lively if you want, or not, 6-7 minute flights are easy to achieve. It would be a little ripper on 11000 I think. Wouldn't mind trying that. Best news is my "tweaked" shaft is true. Little or no jello. So I don't need a motor right away

FYI, I got a response from BetaFPV today, they do not plan on making more of the motors that came on this PNP quad. So if I damage or if one dies I'll be having to replace the whole set.
