Hello rankamateur
See on this thread -- There is mention of cost of the gear box overhaul. The overhaul interval looks like it has wheels on it, because the time is bit like an auction "Keeps on going up". We started 200 or 300hours now it is at 1000hours just wonder what is the true value.
The other question, "How often are the hoses changed out and how much do these hoses cost."
The original Rotax engine cost plus all these bits and pieces compared to the cost of the Jab engine, looks like there is a fairly even race.
Regards
KP.
