Different airplanes, same mission. Two seat traveling. Either one would work for that.

Also don't get too hung up on the word justify. Its not so much justifying as understanding what the costs will be. All the information I can find says the 9 will be cheaper. But then I see 'yeah but the 14 includes a lot of stuff you'd have to buy anyway if you building something like a 9'.

I'd like to understand what these items are and what they'll cost for budgeting purposes if nothing else. And yeah, on some level I'd hate to go into a 9 because it looks like it will be X cheaper than a 14 and then find out when its all said and done it was only Y cheaper because of things like these mystery items.

If absolute cost is the driving concern, then build the -9; it'll be less expensive than the -14 in nearly all cases. If, on the other hand, value is the driving concern, then it's all down to precisely which aspects/features are important to you.

In other words, none of us have enough information to make a judgement and a complete list comparing the line items omitted from the standard -9 kit and included with the -14 is something which is unlikely to have been compiled by anyone here.

Perhaps simply ask Van's to generate a comparison with an eye toward those specific items of import to you.

Synergy Air teaches a method of dimpling skins with the blue vinyl still in place - you can't deburr with vinyl in place so they're confident in the quality of the holes with no deburring (and my understanding is that Van's is OK with this).

You have to read the instructions carefully though - some parts are common with other models or for other reasons are punched undersized. In these cases the instructions tell you to match- or final- drill, in which case deburring should be considered likely. I like using reamers and found that in many but not all cases holes final drilled with reamer are clean enough that no deburring is needed.
Turner,

Thank you for the info. Much appreciated.

Keith

I am aware of the following:

Final sized holes
Pre-assembled wiring loom
Easy fit canopy

Is there anything else? Any prefab parts that aren't in the other kits or anything? What about deburring, etc?

Your advice is appreciated!

Build per plans, keep your systems/panel/electrical simple, Don't prime. Build at your house/garage, heat your workshop, Install a big dry erase board in your shop for notes, Buy quick release pins for your tatco riveter.

I will have to say this has been a really easy kit to assemble so far. EVERYTHING, just fits! Step by step instructions, really well machined parts and Vans support = AWESOMENESS Andrew got me started by watching every one of his videos and some 3 times over. Thanks Andrew! The only thing that takes most of your time, is prep work like deburring.

I have to think that pilot size has a lot to do with the choice for many. Speaking as a 5’-10”, 155# “pipsqueak”, my 7A fits me like a glove and I would not trade its nimbleness and the performance I enjoy for anything. Although my long-legged 6’-2”, 185#(200# with chute) aerobatics instructor can squeeze in beside me(WELL within Van’s aerobatic weight and CG limits with 20 gallons fuel, btw), he is clearly uncomfortable in my plane and much happier in his own RV-8.

Americans tend to be bigger in all dimensions than they were 50 years ago, so the 14 is a very logical progression in Van’s lineup as it can accommodate almost anyone. I’d have to recommend the 7 or 9 for pilots in my size range, but if I were the size of my instructor, the 14 would be a no-brainer.- Otis

Otis,
I am of similar height but wider, at 185lb, and never felt squeezed in my RV7A. I enjoyed it tremendously but one thing that I like about the 14 more, it is much friendly for a instrument flying than the 7. This, coupled with better nose/landing gear makes it a great choice for me, and the extra room helps too.

Exactly. Although my wife and I are both slim (think the “old” normal - 6’/160 & 5’6”/112), the -14A was a no-brainer. The vastly-improved kit, the increased elbow room, the larger panel area, the friendlier instrument-flying qualities, and the re-engineered nose gear were all contributing factors in our opting for the -14A.

Once my wife requested a nosewheel, side-by-side RV this time around, no other model was considered.

Point taken- although Im hoping the G3X/GTN/GSA28/GMC507 Garmin system Im installing with AFCS and auto-trim will help tame the twitchiness of the 7 quite a bit when IFR. I do also love its aerobatic performance. Got to admit the nose gear on the 14 is relatively bulletproof, though. Im installing Anti-splat but it will still be inferior to that.- Otis

Anytime Ron! Its hard not to have fun, even with all the deburring, when things fit the first time like youd meant to do it that way! And then we all take a little credit when something doesnt look like it fits together but we make it fit! We still say its vans great kits (which it is) but inside we tell ourselves its us
