I tried to attach a Attach a copy of a factory weight and balance cleaned0 up of extraneous comments regarding other than  un-swept wing, non-series V0 etc data. The series V comes in forward swept one degree or non swept wing.0THE0 MAX GROSS WEIGHT RECOMMENDED IS 1550 LBS BUT YOU CAN CERTIFICATE ANY MAX WEIGHT0 YOU DESIRE. The FAA inspectors recommend you use whatever you think your0 estimated max useful weight will be so you don't exceed it in use for insurance0 and accident purposes..The floor and bag are very large but you can also make0 the baggage compartment any shape you want and many people put in a long0 thin-wall pvc tube for skis and fishing poles. Its up to you to keep the c.g. in0 limits. The factory says the MGW is 1550 lbs , Mean Aerodynamic Center 51.10in,0 forward cgl imit 9.96 in, rearward cg limit 14.75 in. The cg limits are absolute0 and must be complied there is no discretion here, only in the max gross weight0 should you use other than factory limits and I don't recommend0 that.

I guess the new series 7 airplanes that will be0 sold will have the 1320 GW that sport pilot allows according to the literature0 being handed out at OSH with a 1550 GVW option, which I think John said is a0 different landing gear being the main or only difference.  Their literature0 shows EW of 750 lbs. which is likely very optimistic, since most Model IV's come0 out in or above that area,  and if you actually come out around 900 lbs.0 which some have suggested you would only have slightly over 400 lbs. for fuel0 and people, or with full tanks of 27 gal, would make it a single place airplane0 for most of us and a max pilot weight of 258 lbs. One of the many0 "loop holes" I guess of the Sport Pilot thing.   Bob U.

I own and have flown a Vixen for 1500 hours.  It weighs 755 pounds

on EAA's "certified" scales.  Tri gear, 1550 Grove gear, Clevelands.

I was very carefull about weight from the first hour of build.  I

am sure a 750 pound Kitfox Super Sport will be acheivable, and am

betting the business on it.  The demonstrator fuselage and weldments

are going to the powder coater now, I'll keep you all posted.   The

Super Sport 1550 option is a slightly heavier gear.



Thanks for the support shown us at Oshkosh!

Just to support what Phil says:  My Series 5 with a series 7 firewall

forward and 912S weighs 776 lbs.  This is with Grove gear, large heavy

tires, adjustable pedals, dual brakes, two 13 gallon gas tanks and weight

conscious building.



750 lbs is not unreasonable.

Have to disagree a bit with your numbers.  First though, I scanned my 

personal achives and found that you fly a Model IV and suspect you have a 

582, is that correct?  I am curious about your empty weight.



My Model IV with R-912 weighed in at 704 lbs with all fairings, spring gear 

and junk like kick panels and carpet.  Mine is the heaviest of all the ones 

in our flying group and the lightest comes in at exactly 100 lbs lighter 

than mine - 604 lbs.



Unlike other claims made by so many people trying to market such things as 

engines, I can't imagine the three guys - all Kitfox owners - actually 

builders and owners - and pilots would begin their tenure at Kitfox Aircraft 

LLC with credibility damaging claims.  Granted the numbers are likely 

calculated, but it is not a group of engineers here, these guys, all three, 

have walked the walk and have a lot at stake  in terms of the success of 

their business.  With the major credibility damaging practices of late 

Skystar, it would be hard for me to understand the new group starting off in 

the same way.

For what it is worth, my Classic IV/912UL with every speed fairing along with a full panel and upholstry/carpets came in at well under 700 (673). Maybe Bob is referring to the V's which likely will exeed 700#.

I stand corrected.  I was going by others weights on IV's and 7's.  A

recently posted weight and balance sheet showed a Series 7 in the 1050 lb.

range I believe.  This just substantiates how different airplanes can be

built from the same parts.  I hope Phil incorporates many of the vacuum

molded parts he made for his airplane also.  What I know for sure is most

light experimentals fly soooooo much better light.  Maybe someone can tell

me if there is much difference in weight of the series 5 vs the 7 and if

someone has already built a series 7 in the 750 lb range.  Bob U.
