It has been awfully quiet. Was Van's at SnF? Anybody hear anything? Or is Van's going dark hoping to surprise us all at Oshkosh when they fly one in?
if Van can help us get into a completed -12 for considerably less... with quick-build features that doesn't turn it into a 3 year project - that makes it obtainable for me.
Sam Buchanan said:I'm also very interested in how the RV-12 shakes out since I realize that LSA may be an option for me someday. However, I have no illusions about the cost of a fresh RV-12 being much, or any, less than a budget-priced RV-9. An airplane rib, spar, or whatever costs about the same regardless of whether it finally resides in a -9 or a -12. The Rotax engine package is going to go for $11K-$15K which is more than a lot of folks spend on mid-time Lycomings.
The RV-12 no doubt with be a fine aircraft which will probably dominate the LSA kit market. But the cost to put one in the air will likely be very similar to the current Vans two-place models that have reasonably priced engines and avionics.
Tell us what you really think. Vans is probably using the Avex rivets. More expensive than standard rivets, but much much cheaper than cherry rivets. They might increase the cost about $100 for the whole project. I built a CH640 with pulled rivets, so I speak from the perspective of a typical builder, not an A&P or someone with extensive experience and skill in bucking rivets. After bucking a few thousand rivets I'm sure it is second nature to get consistently good rivets, but it is very attractive to someone with no experience looking for their first project to use pulled rivets. The main reason to use them are to make construction faster and simpler, with no need for a helper. If designed for them, the resulting structure is every bit as strong as one designed for bucked rivets, there are just more rivets. The finished appearance is admitedly not as nice as flush bucked rivets. Riveting becomes a relatively minor part of the building process (overall time spent riveting), taking less time to pull a rivet than it takes to put in a cleco. It is much easier to get a consistent, satisfactory rivet for the average joe builder. They also have a fairly wide grip range, so you really never have to worry about getting the right length rivet, you use the same length on the whole structure. Don't know about the cherry rivets, but the avex rivets are simple to drill out. Just another perspective.EBSB52 said:If they could do it for 10k out the door, use driven rivets, which I would do anyway - pull rivets just plain suck - then you could have it up in the air for 25 w/vfr instruments. Probably <1,000 hrs build time too I'm guessing.
I can't understand using cherry rivets where there is access. They work, they can corrode, they just suck and are obviously expensive. I have done sheetmetal for 15 years, AP / IA for 23 / 12 respactively, just can't understand using high-priced cherry's when driving rivets is so much fun .
Did I say I hate using cherry's? Then when you go to drill them out as they smoke or wiggle, you trash the skin. Don't get it..........
I'm just hoping they can do it for 10 large
Yup! Just take a look at the Sonex for a good example of an airplane being designed around pulled rivets. Tony Spicer has a great video with aerobatics being displayed in his Sonex...very strong airplane. I'm also helping a friend of mine build one. Very sturdy construction.sadams said:...If designed for them, the resulting structure is every bit as strong as one designed for bucked rivets, there are just more rivets....
