When I bought my fox, I made a few, well, compromises with myself on my requirements for the "perfect plane" as I also needed it to fit my budget. One of the compromises was the gross weight. I bought a kitfox with a 1050 gross weight. I'm now finding out that I will need to carry 2 people's worth of weight (I'm going to assume an average of 200lbs each) and a decent load of fuel. My KF weighs a mere 590lbs with it's rotax 582. The 582 should be able to handle it, albeit slowly. I'd be overweight if I were using the 1050 gross weight so I need to figure out the easiest, cheapest, most efficient way to boost the gross weight of the kitfox. I saw some guy on barnstormers who "upgraded the spars" to increase the gross weight but I don't know if that can deliver. So, I guess my question is, can the kitfox 1050 handle 1200lbs on a regular basis, or should I upgrade? If so, what's the best route to take?
