Hybrid power systems

I haven't posted here since four jobs ago... but I figured this would be the place to ask (even if I have NO IDEA which topic to post under). I am looking for electric systems, but gas powered... so neither of those categories work on their own. Electric battery and charging systems seems to... stationary. So here I am in Mad Builder's corner.

I'm looking for information on getting generator heads for hybrid drones and RC systems. I have seen several hybrid generators for RC, but they're all complete systems, engine and DC generator head. When I look for generator heads I get bulky, underpowered cylinders for home generators or small wind turbines. What I need are the more space efficient pancake heads on the generators like these:


Without spending $15k, the specs and manuals seem to be closed off from me getting to identifying marks or listed replacements, and I'm pretty sure not all of them are making custom generator heads from scratch. Someone has a supplier somewhere...

If there's an alternative motor that I can use as a generator that would also be acceptable, but I can't find anything other than BLDC in the scales I am looking for, which I'm finding is not usable as a generator (according to any source I can find). I will be hooking it up to a custom gas build. For the smaller scales I still end up with bulky motors or generator heads that protrude too far.

I'm not building strictly for air, so weight is not the biggest concern at this point while I work on proof-of-concept in my design. What I need is compact build for size.

I've searched the forums here, or attempted to, but can't find "hybrid" mentioned outside of construction or materials. I'm looking at hybrid power systems, or specifically the electric generation part of hybrid power systems.

Power is preferred above 1kw... but I'm willing to start much smaller as proof-of-concept if I can at least get a hold of a vendor for these things going forward...

I have a skyrc f6000 hybrid drone generator for sale that provides battery charging during flight using a mini gas generator. Can increase fly duration by 2hrs depending on size of fuel tank and drone payload capacity. Shoot me an email keithd1986@gmail.com if you’re interested.

I just saw your post and am working on something similar to what you requested. Did you find an answer to your question? I am curious as to why you couldn't us any BLDC motor, with a controller, as your generator head? I am trying something similar with a VESC controller, used for skateboards, large 80100 BLDC motor, and an MVVS engine. I put the VESC in regenerative braking mode which turns the BLDC into a generator. The biggest problem I am finding is the output power from the VESC is current controlled, and voltage isn't regulated, so I am trying to add a circuit to control regen output based on voltage at the load so I don't blow up my batteries
