I can produce a hybrid power plant of components I produce in my company www.flame-power.com
- 2-stroke engine weighing 4.5 kg
- generator electric starter weighing 2.5kg
- 1.5kg weight control unit
- reduction gear, etc.

So far, this is a rough guess, requiring clarification:
- power of the gas motor 15 hp at 7200 rpm,
- max power of the electric motor during take-off 34 hp
- continuous power of starter-generator in electric motor mode 12 h.p.
- continuous power of starter-generator in generator mode for battery recharging up to 10 h.p.
Capacity of electric buffer electric battery 40ah, weight 8kg to ensure approximately 8 minutes of pure electrical flight.
It seems enough for safe landing if required.

Consumption of a gas engine shuld be less than 4 kg per hour. Says 2 hour motored flight are enough.
Is such parameters optimal and sufficient? You can change everything proportionally. Do I need use gearbox?
If so, the optimum revolution diameter?
