Status: offline 		Has anyone ever tried to swap parts (wings, stabs, hatch, cowel) between the two? I have a V1.1 and could see some weight saving potential there.

Status: offline 		Wings would peak my interest more than anything else. My CG is at the forward end and the weight savings might be pretty good. 1lb12oz is what a v1.1 weighs per wing. That's with all components installed ready to fly.

Are you flying the v2 now? How does it compare? Any idea what the wings weigh?

I'll put mine on another diet when I put smoke in, although I'm not sure what else to lighten. I've done all the normal stuff (besides batteries) already. Now it would be a couple grams here, a couple grams there.

Status: offline 		1lb5oz sounds pretty good. I could save nearly (14oz) a full pound of weight off the wings if the Edge wings are as light as the Extra wings.

Status: offline 		Yes, I'm flying my second v-2 now. V-1 flew very well but v-2 handles and flys better. Both of the v-2 versions have been a bit over a pound lighter than the original v-1. About the only thing you can do wrong, even if you try very hard, with the v-2 is get too close to the ground. Which explains why this is my second v-2, and moving on from the original v-1

Status: offline 		I checked a set of v-1 wings against a v-2 set this morning. There definately are differences. The wing root of the v-1 wing is 21" wide, while v-2 is 21-1/2". A v-1 wing on a v-2 fuselage places the leading edge of the wing about 1-1/2" forward of where it is with the v-2 wing on the v-2 fuselage . Anti rotation dowels on the v-1 wing do not mate with the anti rotation dowel holes on the v-2 fuselage. I do not have a v-1 fuselage to try with a v-2 wing.

If you could measure your fuselage, noting the center of the wing tube distance to aft end of the plane I could compare wing tube locations between the two fuselages. Also note where the leading edge of the wing is relative to the aft end of the plane. The aft end of the plane should be considered the back edge of the vertical stab, not the end of the rudder. These are critical dimensions since they establishe the center of lift relative to moment arms and the MAC. Your C/G is predicated on those, and the horizontal stab is located to offset aerodynamic forces accordingly. If the v-1 wing tube location will permit the v-2 wing to be in the same location as the v-1 then you could simply re-drill the holes for the anti rotation dowels and the wing bolt. Ailerons on the v-2 wing are substantially wider than those on the v-1.

If the dimensions do not match and you elect to try a set of v-2 wings on a v-1 plane you will instantly become a test pilot, and the c/g locations referenced in the manuals will be useless. I had to put that in there as a fair warning.

Edit:

There is a difference in distance from the center of the wing tube to the leading edge between the v-1 and v-2 wings. With v-1 that distance is 6-7/8". With v-2 the distance is 5-11/16". Unless the wing tube location on the v-1 fuselage is father aft than it is on the v-2 fuselage, the main wings will likely not be interchangable. V-2 was a complete redesign of the plane with many changes and improvements taking place, so I would be surprised if there was any interchangability between the two at all.

Look at it from another perspective. V-1 was a great flying plane at any weight and v-2 just made it better. There will be no lack of enjoyment flying the v-1. It's just not possible. There's really no reason to have any concerns or worries at 17-1/2 pounds. That weight is there or better than the average all up weights that were obtained at the time. A few people made it to 17 or the very high 16's, but they spent gobs of money on carbon parts to get there. Just leave the wheel pants off and go fly

Status: offline 		Surfer -
You couldn't be more right. I was hoping it would be plug n' play, but the differences are substantial. From what I can see, the only thing that the two versions share is the Wild Hare name. Beyond that, they are completely different airplanes. My challenge to myself, was to come in as light as possible, while still building on a budget. I feel like I have met my goal and the expense of more upgrades may not be worth the extra weight savings. On that note, I did read on a forum (maybe on here) where a guy was experimenting with a geometric pattern that was cut into the foam in a balsa skinned wing. I saw some pics of the foam, but never saw any of the finished product, let alone, how it flew. I saw Tom had some V1 parts left on the site. I may have to pick up a pair of wings for an engineering project for NEXT winter. That assumes the Edge survies THIS summer.


Thanks for taking the time to research those numbers for me.

Status: offline 		You're welcome. I have a set of v-1 wings as well. The tip on the right one needs some work at the leading edge but it's easily servicable. I've been hanging on to them for the day someone needed a set of v-1 wings. Unfortunately usually the fuselage takes it in the shorts first...
