This question is primarily for those who have been flying for a while
and have gained significant use experience. I believe the response will
be very helpful to those of us who are in the building process and
wrestling with decisions of what to put into our aircraft in terms of
electronics, engines, modifications and also useful techniques used to
complete the building process. I am not asking for what is best (no
primer wars here) but for what you believe you learned from your experience.

If you were starting to build an RV-10 given you current knowledge
gained from building and flying you RV-10, what would you do differently
in completing the project?

I would have used a bigger screen on my AFS EFIS.  Turns out that some of the text is a bit hard to read.

I also would have been clear to the interior shop that weight was an issue.  I think a little more care on my part there could have saved maybe 50 lbs. because of all the soundproofing that went into it.  I really like the interior but I still choke when I think that it was over 100 lbs, not including the front seats.

We switched from the vernier controls to a throttle quadrant after we'd been flying awhile.  I like the quadrant much better.

We added oxygen after using the plane for a while.  I didn't think O2 would be a big deal but it really increased the utility of the plane.

There's probably a longer list but those are the big items.

Well, I will jump in here. First of all, I would definitely build this airplane again. I really love it.

Things I would not do again and why.

1. I would not use aftermarket upper and lower main gear intersection fairings. I don't think the price difference is worth it and I don't think the work involved would be significantly different.

2. I would not install the tires and tubes that come with the kit. The change to Desser retreads and leak guard tubes has put an end to my constant low tire pressure problem on the main gear. The nose gear tire and tube are still stock and they have no problem.

3. I would not install electric rudder trim. The manual trim from mlskunkworks.com would be my choice. ( I definitely would want rudder trim)

4. I would probably not install Chelton EFIS if I was starting today. I really love my Chelton's and they have not skipped a beat. But, it became obvious that the new owners of Chelton were not going to market the Chelton Sport going forward, so I have some concerns about long term support. If money was not a concern, I would consider the certified Chelton equipment. I suppose I would reluctantly take a look at Garmin.

Things i would do again and why.

1. I would buy the Quick Build kit. I know there have been some issues with the new factory, but I still think it is a good value. It got me flying at least a year earlier and that was important to me.

2. I would definitely install the Vertical Power VP-200 again. The ability to see what is going on with the electrical system and each and every electrical component is wonderful. Simplification of wiring and the ability to customize individual circuits is very nice. The emergency management function is great. Things like variable speed pitch trim control, wig-wag, electronic checklist, and much more are icing on the cake. Fantastic product and great support from VP.

3. I would install the extended range tip tanks. I really like being able to load up on cheap fuel when I find it. The extra one hour + endurance gives me much more flexibility selecting alternates. The kit is a bit pricey, but is well designed, has good instructions, and is easy to install on a Quick Build wing.

4. I would install air conditioning again. I selected the Flightline AC kit. It has not been trouble free, but support from the factory has been outstanding and it sure is nice having it in Florida! This kit did move my CG a bit aft and added around 65 pounds to my airplane. I have an MT propeller and the Hartzell might be a better choice in this application since it is 17 pounds heavier. That would improve the CG issue.

5. I would have SteinAir build my panel again. First class operation!

6. I would have Flightline Interiors do my interior again. First class operation!

7. I would install the AirWolf remote oil filter mount. There is plenty of room on the firewall and every time I change oil I am so happy I have it.

8. I would install the B&C starter. Fine piece of equipment. Same goes for their alternator and voltage regulator.

9. I would install the Lightspeed Plasma ignition again. I have had no problems with it. (I have the EI on the left and a slick mag on the right) I am still waiting for the 6 cylinder PMag and would consider that for both sides if it was available.

Things I did not do but wish I had:
1. I would install a built in Oxygen system.
2. I would use the McMaster Carr door seals
3. I would get knowledgeable help with my cowling. The fit and finish of this is my biggest disappointment.
4. I would install inertia reels on the front seat shoulder harnesses.
I know I will think of more, but this is already turning into a novel, so I will stop here.

My 2 cents

1. Not install the center console. It takes up some knee room on long
flights. Harder to service the tunnel.

2. Move the inline gas filter to two smaller units under the seats.

3. go with LED wingtip lights from the out set.

4. simplify my panel. I have two AFS efis panels, one for the co
pilot/one for me, Put it all into one in front of the pilot. I do
like the unit.

5. Get the upgrades on the front axle from the beginning. I never had
any problems with the stock one, but the matco upgrade is worth the
upgrade.

6. simplify the audio panel. All the rear jacks/entertainment just
isn't very useful. As long as you have XM weather and radio, not much
else is needed.

7. fix the loose steps before I closed the lower pan. Still gotta go
back and cut holes in the floor to stop the wiggle.

8. Read and follow the recent updates on the door construction and
installation. It will save you time and money and frustration. The
doors are doable, and you can get great results, if you go about it
correctly.

Agreed. Certainly differences of opinion on certain items, but great
for stimulating thought and either deleting/upgrading/justifying items
and where/how they are installed. Working on deletion/addition list
for ordering finish/FWF kits.

Do different:
1. Nut plate the rear floor or at least put in the 2 inspection plates that I did over the steps.
2. Provision for an easily removable portable Oxygen bottle. This plane likes to fly high. Not a big deal and can be done after certification.
3. Put in a regular VOR antenna for IFR navigation.

Glad I did:
1. Kept the mods to a minimum for a quick build cycle (I did it in 32 mos)
2. Must do mods - SS heated air box - rivethead door pins - Alex D's high capacity oil cooler - at least for flying out west.
3. Insulate the firewall
4. Simple panel - LED lighting kit
5. Keep the weight light (See Tim Olson post). This is a biggggg deal after you are flying. I have almost no interior. I am at about 1630 lbs. Most seem to run about 1700 lbs. Comfort or capacity - your choice....

Now coming up on 400 hour TT, and loving this bird a little more each time I learn something new about it:

Do differently:

1. Install the Safe-Air1 auxiliary tanks during the initial build. A pain after the wing is painted, and they are the single most dramatic thing for expanding cross country options.

Do the same:
1. Keep it light. Mine came in at 1525 and is no showplane but a great performer.

I knew I would think of some other things!

I agree with Dr. Fred about the Matco front axle. Do it during the build.
I agree with Mike about:
Stainless steel heated air box
Insulated firewall
I used the iflyrv10 billet door pin blocks and they are very nice.
Alex D.'s high capacity oil cooler.

I highly recommend rudder pedal extensions sold by mlskunkworks, Blue Sky Aviation, and others.

Alex D's Blue Sky sun visors.

I'm close to flying but not there yet, so I can only comment on building issues.

I would put more conduit in for wiring, and try to find a smooth inner wall - Van's conduit is ribbed and is difficult to run additional wires through.

My two cents,
John

Tie a piece of paper towel on the end of your pull string and tape the
other end next to the conduit. Stick it in one end of the conduit and
your shop vac in the other. If you didn't tape the free end of the pull
string down you might find all of it in the shop vac. Wink

I haven't put any insulation on my firewall. Can anyone flying who
hasn't insulated the firewall comment on the situation? What is your
experience with an un-insulated firewall?

I kind of want to ask the same question about the SS air box but I think
the only issue there is safety in case of firewall forward fire. Is
there anything else?

Bill "superfil is good" Watson,

Besides fire, the ss boxes have baffles to prevent any hot air from leaking by the doors and into the scat tubing...

Bill - a couple of issues with the stock heat boxes:
- they're aluminum which partially defeats the purpose of having a stainless steel firewall since they're the only thing between the cabin and a pair of 2" holes.
- the hinges on the stock aluminum boxes are sloppy and are at least part of the legendary "hot tunnel" issue. Air from the opposite side SCAT causes the flapper to lift on the hinge side and allow hot air in even if the flapper is closed. You won't feel flow but will get hot air in there.

Although the SS airbox will buy some additional time (probably not enough to
land and exit), a better solution to the fire problem might be fire bottle.

In any case check the chemical composition of the material and any gas given off while hot or burning

My good buddy and RV-10 builder optede for the SS heat boxes. I didn't
.... yet.
He had some thin red silicone sheet that he bonded to the flapper to
seal the hole when closed. I did the same (he gave me enough to do
mine) bonding the sheet to the flapper with red silicone from the tube
and closing the flapper while the silicone cured.
I'm into fire prevention (I know it's impossible to get it 100%) rather
than fire mitigation.

Bill - a couple of issues with the stock heat boxes:
- they're aluminum which partially defeats the purpose of having a stainless steel firewall since they're the only thing between the cabin and a pair of 2" holes.
- the hinges on the stock aluminum boxes are sloppy and are at least part of the legendary "hot tunnel" issue. Air from the opposite side SCAT causes the flapper to lift on the hinge side and allow hot air in even if the flapper is closed. You won't feel flow but will get hot air in there.

The insulation, I believe is for heat dissipation, as well as maybe noise? I
went with a spray on noise than ceramic insulation, I can tell you that the
"bang test" where I hit the firewall with a wood block before and after the
spray on was rather significant, I also grabbed a heat lamp and let it sit
for 5 minutes pretty close to the firewall, the heat was hard to touch for a
few seconds on the fore side and bearable on the aft side with the
insulation, so it must do something.
I have the plane innovation heat vents, I don't know if Paul stuck with the
same design as mine has, as I know he is always doing more fire tests that
result in his needing the fire crew to come out when the neighbors see
smoke (he takes the smoke and fire testing very seriously) but mine
literally blocks any forced air to come into the vents unless the doors are
opened a little bit. I grabbed a heat gun and shot it through the SCAT tube
and had someone tell me when they felt any heat at the cabin side vent
(without a SCAT tube installed) no heat at all until the vent was pulled,
there is no doubt they are worth the money. I don't know what they will do
for smoke blockage, but whatever it is, it is far better than the aluminum
vents that are part of the kit.
Skip the Vans vents and get the Plane innovations one, they may save you
extra work with the tunnel heat issue, I can confirm that when I actually
fly but based on my limited heat gun testing I can't see how there would be
a tunnel issue with the vents closed.

I haven't put any insulation on my firewall. Can anyone flying who hasn't
insulated the firewall comment on the situation? What is your experience
with an un-insulated firewall?

I kind of want to ask the same question about the SS air box but I think
the only issue there is safety in case of firewall forward fire. Is there
anything else?
