Why? I mean, they're bigger and there's more of them, but any other reason?

For me, the biggest SB vs QB consideration is whether I really enjoy building. I'm not far along enough to determine that yet. But if I went SB and thought it was drudgery, it'd take me twenty years to build this thing. On the other hand, if I really enjoy it and can't wait to get home and do another couple of hours in the shop every day, then it'll probably go much quicker.

As far as the money, well, for me, $8,000 is a big chunk. But can I honestly say that I can scrape together $60,000 but I can't scrape together $68,000? Either one of those figures is pretty damn daunting, but the percentage difference isn't that much.

well, size doesn't matter :mrgreen: , and the fact that there's more of them doesn't matter, it's the repetition of the work being done that i don't like. that's NOT to say that i don't enjoy being out in the shop working on the airplane. it is to say that my arms and wrists hurt from the same motions over and over again. i don't care for that part, but i DO enjoy it nonetheless.

$8,000 is a big (huge) chunk for me, and i would much rather spend that $8k on my panel, than paying someone else to build part of my airplane for me. (no offense to you QB guys, i know there's still a TON of work to do w/a QB). i plan on doing my panel (day/night VFR) for about $6k, so the savings are even greater for me, but if i need that additional $2k... :roll:

The quick build wings can be done pretty fast. I on the other hand had my head squarely up my rear and jumped into the middle of things :bang: . Hence I have since posted a better order of the finishing process. I felt it took me far to long to finish the wings but I had Christmas and New Years to deal with and the shop didn't win that war. So the project sat for nearly four weeks with nary a thing getting done. As far as the fuselage goes I have been looking over a few of the better build sites Dan Checkoway and Walter Tondu are a couple of the more informative (but not the only) I've found and are both linked from Rivetbangers. What I have found is that the fuselage when it comes as a QB is at the point of fitting sub assemblies. Canopy and wheel configuration are left at a stage that the specific installs need to be dealt with. Other than that it becomes assembly and fitting of all sub assemblies and the occasional optional part. There is a good deal of minor disassembly involved and some loose ends are left since options such as a step(s) need to be able to be addressed. Looking over builder sites it has become obvious that many builders tend to fall into the trap of putting the cart before the horse by attaching sub assemblies that latter need to be taken off in order to attach other sub assemblies. In my case I recently installed my baggage compartment floor only to realize that I needed to first install a left and right step requiring re removal of the baggage floor. What I have found is that the QB is a one size fits all solution that may or may not need modification by the builder. Aerobatic tanks would be a nice option in the wings but that's not available in the QB at this point so a builder is left with that to deal with. Also no return line for a fuel injected engine. On that point I could use some input from the Captain. All in all a lot gets done on the QB kit for you but it's not the great boost that some seem to think it is but more like a modest leap. It's worth remembering that the QB's are still well within the 51% rule.

Peter,

The tanks took WAAAAAY longer than expected, but that could be my stewing over the little things and the insisting on vapor return lines.

Other things are pretty much the same as the emp kit. The package makes more assumptions, expecting that you have become more knowledgeable.

Nothing really unconquerable at all. Post pics and I will try to point out the "gotchas" along the way!

Keep us informed!

Why cut down on the fun...

Post by ldbedard »

My son in his great wisdom told me, but dad why would you go QB and cut down on your fun of building....

also, many would consider matched hole to be quickbuild... :)

Quick build all the way....

Since this is my first time building I had 2 main reasons why QB
1. I want to fly ... not build
2. I want the Factory building experts to build the structural sections

With a partner, we finished all but the glass work on the emp parts in 5 days @ Alex Tech, Griffin GA... great way to learn how to work alum sheet metal

Started last week in Sep 05, we are now going to mount the wings and emp to the fuze next week... should be flying by Sep 06.. Working one night per week and all day Sat.

The workman ship in the QB is much better than I could have hope to accomplished .. Not as good a Boeing, much better than Cessna. Van's does it right..

If I'm honest I have to say that I am more excited about flying my 7 than I am about deburring more edges which is why we originally looked QB.

However, we REALLY want to have our bird paid for the first time we fly her and with everything we have planned from paint to panel, an extra year or two on the build gives us more time to tuck away what we'll need for engine and panel! (not to mention the extra $8000 + in savings over the QB) We mapped it out to the dollar and for us, we just can't build the plane we want and pay for it in two years. We can in four.

I know that's big talk for someone just starting his build but we're actually really having fun with it so far! (isn't that the idea?!?) We may change our minds after we're covered in tank sealant and buying our 20th set of deburring bits but we'll cross that bridge when we get there. :mrgreen:

For now, we're staying on our financial plan and hope not to invite any loan officers from our bank to our first flight!

Peter, that's not big talk... that's planning. If you don't plan for it, nothing will ever happen!

I am in the same boat as you. Lots of ideas, not alot of money. The extra build time combined with the additional savings should tip the scales for me to make the plane of my dreams.

I agree CJ...

If we didn't map it out, we probably would never end up with the IO-390 / IFR panel etc.

We just do the math backwards, put it in the financial calendar and follow our own direction. ...funny the dual Chelton panel put us out a little too far! :)

same here peter. though, we'll have to borrow for engine and panel, i think. i can come up with the money for the airplane, but after that, the purchases get really steep, and i'll probably be inviting my loan officer to the first flight. we'll see how it goes, but that's the reality for me... :roll:

The reality is that we all have the dream of flight in our own personal high performance flying machine! It's all about choices.

If Beth and I don't borrow to finish our -7, I'll probably still be driving the same car with about 130,000 miles on it. (...notice I said "I WILL BE" not "BETH & I WILL BE"!) :roll: If I get a new car along the way, we'll certainly need some help finishing 200PF off...and so on and so on ->

Oops! I called her by name aready and all she's still just a box of parts! :mrgreen:

At dinner tonight I was just calculating my next planned car purchase. *I* don't *PLAN* on getting another vehicle for at least 5 years. I looked at my annual mileage and it seems that 12,000 per year is the average for the past three years. My little JEEP has 103,000 on it now and runs better than the day I drove it off the lot!

At that rate and the way the JEEP is SIGNIFICANTLY overbuilt along with good periodic maintenance I should be good right up to about 200,000+ miles! When I bought it I was planning on 250 anyways.

The wife on the other hand is already looking at new Cherokees. The one she has now is an '04 with 22k on it, but she wants the HEMI! I don't blame her. I do too!

I drove my Dodge pickup to 200,000 before replacing it and now my son drives it. Still runs great. :)

My wife put 210,000 on her Ford Expedition and we finally just sold it and got her a new Jeep Grand Cherokee. I bought another Dodge pickup (yes, it has a hemi).

We used to buy a new vehicle every year but these two we finally decided to drive till they dropped. I got a little nervous after the 200,000 mile mark so decided we better do something. Longest I have ever owned a vehicle, my old truck was a 97 and the wifes Exp was a 98. My new one I got in Sept already has 14,000 miles on it.

Cars will run a lot of miles if you take care of them! With out a doubt I'd rather have more goodies for the plane than a new car at this point but you gotta do what you gotta do. Having driven the previous ones so far helped pay for the emp and wings and busines is good so hopefully it will stay that way and I can support my new habit. :wink:
