It's a nice scenario but I'm afraid not a very realistic one. First off, I'm not sure that anyone in this industry has actually sold 1,000 plan sets in the last fifty years. I'd be rather doubtful if anyone sold even half that.Hello
Unfortunately I went to school to become a mechanical engineer not an aircraft designer. A well designed LSA amphibians seaplane set of plans could easily be sold. The cost of the plans could be 400 dollars. Total sales for 1000 plans would be 400,000 dollars. With sales like these all kinds of stuff could be done and it could be tax deductible.
Sorry but I dont get it, what's a problem? There are few guys here that designing and building their own planes and they don't have even mechanical engineering title. Personally I think that you have three ways: hard way, expensive way and "easy way".Unfortunately I went to school to become a mechanical engineer not an aircraft designer.
The fuel quantity, range, and engine don't add up. An O-200 at 75% burns closer to 6.6 GPH (Continental's own numbers: .54 lb/hp/hr x 75 hp /6.15 lb/gal) and you need to allow for takeoff and climb at 100% prior to estimating range. Depending on what assumptions you make about cruise altitude for termination of the climb you'll probably need closer to 50 gallonsHello
Fuel Capacity = 35 gallons
Range @ 75% = 7 hours no resrve
Speed = 120-125 @75%
Power = Continental O200 or IO240
Yarrrr, where be your keel?But in the process I thought of a great idea. How about tipping one of the removable wings straight up after landing and sail along using the flight controls? You could move around and pull up to a dock with out knocking every body off. I've never tryed sailing a seaplane yet.
