I built and currently am flying a miniMAX 1600R, the mid wing that the HiMAX is based upon. Here is a link to see my plane, http://www.jdtmini-max.com/builders/bogenhagen.php I built the plane in the basement of my house over a 5 1/2 year period or 1089 building hours, varnishing, covering and painting were done in the garage. I thought the plans were excellent and very easy to understand. The plane can be easily scratch built or a kit of raw materials can be purchased from JDT MiniMax in Napanee, IN. Building from a kit makes it easy and saves time because everything you need is already there.
I have 115 hours flying time since first flight in 2006. It is a nice flying, lightly wing loaded, STOL light plane. Mine is registered experimental amateur built, weighs 369 pounds empty, economy cruise is 70 mph buring 2.8 gph, stall is 35 mph.
I started building a HiMax a couple years ago after I finished the miniMAX. I found a great price on a kit that was purchased some years prior but never started. Its fun to build, and the HiMax is allowing me to keep building without alot of money invested. These aircraft are a great value, not alot of money is required to complete them, and they are real nice light planes. The obvious draw back of them is that they are single seat. However, the only dis-advantage of that is you can not take a friend for a ride. Single seaters are actually great because they are lighter, perform better, more maneuverable and cost less. Think about the handling differences of a small sports car versus a larger 4 door sedan.
I highly recommend the HiMax.
