Thanks guys for all the replies and advice
The model is 2.5 kilograms, I think they made a typo. Clovus, I know what you are saying, but Ive thought it all out already. The model is fibreglass, so no need of fuel proofing. A rag is all I need to clean it, a glow plug ignitor is the only thing I actually need to start it, (I already have one), the noise and smell and feel reminds me more of the full scale planes, and any additional things really don't bother me too much. That doesn't mean Im only going to fly glow though, I will be a mixed flyer, I have too muvh electric gear and good memories to abandon electric models, and when the price comes down a bit more, I will probably convert completely back to electric.
