Still thinking about an RV-14

[TCABM]

Anyone remember these days from iamtheari’s original 2017 post… long gone..

What does the RV-14 do that the RV-7 doesn't, other than cost more to gain a little bit of cabin space?

The dollar figures are:
RV-7 kit: $23,680
XIO-360 (180hp): $28,700
Hartzell prop: $7,775

RV-14 kit: $33,800
XIO-390 (210hp): $33,800
Propeller? assume same: $7,775

So the basic airframe and powerplant are $60,155 for the RV-7 and $75,375 for the RV-14. That seems like quite a price bump for unspecified gains.

I get the rhetorical aspect, but power plant cost is a red herring. The $10k in kit costs buys you quicker and easier assembly, 2’ of wing span, and 8 gals of gas. You theoretically complete the kit faster while gaining an hour of range on every sortie.

The lure for me was the higher useful load, supposedly better kit builds (not referencing the quick build kits here) but I believe they had more CNC involvement which meant better/easier/quicker builds.
From a not so good memory:
Also the fiberglass work was refined/reduced.
Luggage area was larger.
50gal fuel vs. 42gal
I thought I read that the landing/nose gear was a little better.
ETA:
A little higher wing loading. Not a game changer, but better for bumps and maybe IFR/stability. (arguable)

I probably would have voted for a slider vs tip-up but that isn't an option. I guess you could do your own, but that would entail more than just the work regarding getting it signed off on for airworthiness.

If you guys were trying to talk me out of a 14, you're doing a **** job.

Jim, why a 14 and not a 10? Or a 15? What would be your mission? I ask as I'm internally making the case for each one myself.

The 14 because I don't really need 4 seats, but light acro sounds fun. The 10 because it doesn't sound like that much more work or expense in the macro. Plus I've always seen a 4 seater as a 2 seater with baggage space. The 15 because bush tires look cool.

You don’t even want me to talk about lead times. Suffice it to say that my January 2018 empennage kit order was delivered to me faster than any of my Amazon Prime orders in the past two years have been.

 

[Skyrys62]

I like the 15 too, thinking it would be a fun and useful plane.
I'm guessing a 10 for Jim would lose seats/useful load, while still incurring higher engine rebuild cost.
However, if he's going to make 3 trips to Oshkosh every year anyway, 4 seats might be plenty, and definitely faster

 

[Jim K]

In today's money,
RV14
Kits $61,300
New engine $55-60k

RV7
Kits: $46,250
Engine $45-60k

So an additional 15-25k depending on what you want. As a 6'4", 275 North American male, I'll take every mm i can get. Also remember that I'm acclimated to a pa32. I sat in the -14a at osh, and it felt good, but i wouldn't want it to be much smaller.

Jim, why a 14 and not a 10? Or a 15? What would be your mission? I ask as I'm internally making the case for each one myself.

That. I would envision keeping the lance for heavy hauling/ family truckster type missions. The -14 would be a little more efficient for solo trips and the occasional roll.

A -10 doesn't do anything the lance doesn't already do better except maybe be a tiny bit faster. I'm not into the -15/stol/ backcountry/ flat-brimmed trucker hat scene. Maybe if i lived out west where there actually is real backcountry. The lance has gone everywhere I've wanted to go, and a -14 can supposedly takeoff on under 400' at max gross even with the little engine. I'd consider a -8, but I don't think Teresa would like the tandem seating.

There's no real difference in the fiberglass. You can get the reengineered nosegear for all of the side by side models. But the -14 (and -10) kits are prepunched in such a way (dunno how) that they don't need the holes deburred (supposedly). Beyond that, I don't see a huge difference in the build process between a -7 (or 9) and a -14. The -10 is a different animal, even after the two additional cylinders. The canopy on a -14, -6, 7, or 9 is a hundred hour task. The cabin top and doors on the -10? 300-500 hours wouldn't surprise me...

The -10 is an amazing airplane. Simple, fast, comfortable, hauls a big load.

Ah, so instead of buying a PC-12, you’re building a second airplane. . Is Teresa getting her license or are making the oldest get theirs?

 

[moparrob66]

Im drawn towards the BD-4....should go together faster than a Vans kit, and plenty fast with a smaller engine. Not as pretty, but close enough.

I figure if I start now, i might have it done by the time the 6yo is ready to solo.

Put those small hands to use and hold the bucking bar.

Practice kit showed up a couple days ago, but the tools they tell you you'll need on the website don't match those on the instructions, so I'm waiting on some more stuff. One task I CAN do is build the back riveting plate, which is just a small steel plate, but includes a hole for dimpling up close to ribs. I decided I should use a drill press to make sure that hole was square, so I got that set up:



Missed this old girl. Haven't had it set up since we moved, and it was making me really sad seeing it in the corner getting dusty. It'll be nice to have it usable again.

I've been watching every RV build video I can find. Dropping subtle hints around the house like, "I'm going to build an airplane". Teresa has not said "no" yet, so that's a good sign. In fact today I got an "I know", so I think that means it's safe to order the kit.

Love my the Bridgeport series II I've got in the shop. Won't let anyone else touch it. Doesnt get run that often though.

I don't think you're being very subtle. But congrats on having an awesome wife.

The real skill you need to learn (IMO) is how to operate a rivet gun and bucking bar. Everything else (at this point) is dead-nuts simple. Riveting with a gun and bucking bar is a hand/eye/feel/coordination skill that takes time to develop. Kind of like welding. If you wanna practice for the real kit, buy some aluminum and practice by drilling holes, deburring, dimpling some of the holes, leaving some undimpled and driving a mix of 1/8 and 3/32 rivets (both flush and button head). Do 20 of 'em 3-5 nights/wk for a month, drive them in unusual positions, drive some by braille, practice with the gun in the left hand for some, the right hand for others, same with the bucking bar(s). Practicing now will eliminate a ton of frustration as you work on the empennage kit.

 

[nauga]

Also not a bad idea to practice with someone else bucking and you driving, and vice-versa.

Practicing now will eliminate a ton of frustration as you work on the empennage kit.

The practice kit seems to be pretty well thought out to force you to drive some with the gun, some bucked, some back riveted, different sizes, round heads, flush, even a few blind rivets. The first project is just 3 sheets of aluminum and an angle, with instructions to layout and drill all the holes, match drill, & rivet. Second one is building a small section of control surface, so there's back riveting of skins and working by feel inside the part. Plan to work through both kits, then drill out the rivets and do it again. If I'm still having fun, I might order the empennage kit.

I did do some more reading about the bankruptcy today. Some mentioned not being willing to buy kits one at a time any more in case the company goes under. Seems to me that they're over the hump and are going to come out in one piece. Even if not, surely the IP would live on? I mean, you can still buy parts from Mooney.... Am I being naive? I could afford this if I string it out over a few years, but buying all 4 kits at once just doesn't work right now.

Van's hasn't released an update on the bankruptcy in several months. I'd appreciate an update...

One thing I have heard (unconfirmed as far as I can tell) is that Van's is pulling back some of its transition training aircraft from the field. If that is true (as opposed to "We took it away from Bob, but are looking for a replacement check pilot in the Midwest."), I don't like it. Having several transition training pilots around the country was a real asset for Van's customers. If that is going away, well, it could be a sign of other problems...

Drove my first ever solid rivets this evening. Fun & easy, although admittedly with the part stood up in the vise with easy access to both sides. Little gap between the sheet and the angle, which i think means I didn't countersink the angle enough.

It can also mean that you didn't have the pressure right on the bucking bar, gun, or air hose. Or debris between the parts. Some of the kit instructions are "drill and cleco a whole bunch of holes, but uncleco and re-cleco the entire assembly every few holes to clean out debris." You get to discover every single way to screw up a rivet while you're building. That's part of the fun.

Will you say that after 24,000 though?

 

[tsts4]

There’s a number of tips when it comes to riveting. I had a little chart for gun pressures depending on rivet sizes (-3 [3/32] or -4 [1/8] and length); it also depends what type of gun you have: 2X vs 3X. I don’t know what tools you have but a swivel flush set will help prevent dings with the flush rivets (426s) and adding a couple of pierces of masking tape on the cup of the universal sets for the universal rivets (470s) will help prevent smilies. However, keeping the set as perpendicular as possible to the manufactured head and using the right pressure is the best way to prevent damage to the material but it’s gonna happen at some point so don’t obsess over it. On the shop side of the rivet, a tungsten bucking bar is highly recommended as it’s super easy to control and produces great results. That said my preference is to squeeze all rivets (with a pneumatic squeezer preferably but if it’s only a few rivets then the Cleaveland Tool “Main Squeeze” manual squeezer) that I can and only shoot and buck those that can’t be set any other way. My final bit of advice is when you reach the point that you need a riveting partner, in my experience it’s easier to teach a rookie how to shoot vs buck.

PS-you’ve got a ton of dimpling in your future. I suggest investing in a DRDT-2 dimpler,

Sounds like resignation. Do you need to get her to exhibit the rest of the hazardous attitudes first?
