Welcome to RV8.ch! This little site will document the progress on the building of our Van's RV8 experimental aircraft. We will load lots of images, tips, tricks and techniques that we learn ourselves and from others on the net. Please visit the Photo Gallery!
A short introduction to the RV8 from Van's aircraft.
Danny King's "Beautiful Doll"
Information about Van's Aircraft RV8 can be found here. http://www.vansaircraft.com/public/rv-8int.htm I chose this plane because I want a tandem, not a side by side seating. Tandem allows the best visibility on either side of the aircraft. When I want to fly side by side, I can use one of our aeroclub's Pipers (http://www.aero-club.ch/)
I have decided to equip my plane with the following:

Finally, I've ordered the new engine. It has been a long time since I've done anything with the project - about 5 years.
I ordered a Mattituck TMXIO-360 with roller tappets, a forward facing sump, Airflow Performance Fuel Injection System, dual p-mags, and an alternator. The engines come
Here is how Mattituck describes it:
Your TMXIO-360 engine will include New Lycoming cylinder assemblies, the new roller tappet technology, our full Red Gold Performance Package, 2 New P Mags, harness, and aviation spark plugs, a 12V Sky Tec lightweight starter, new fuel pump, a new Airflow Performance Fuel Injection System, inner-cylinder baffles, dipstick tube and dipstick, oil filter adapter and oil filter, new dynamically balanced VAR crankshaft, static bay balance to within 2 grams, vacuum pump drive adapter and drive, starter gear support and ring gear, engine logbook and operators manual.
Delivery will be about 14 weeks. Considering I've taken 5 years to get to this point, not a problem.
Now, just need to get myself a prop and the firewall forward kit from Van's, and I'll be just about set.

I've decided to sell my Eggenfellner Subaru STI engine. It is a FWF package including an electric 3-blade MT prop with prop controller, RV8 engine mount, supercharger, intercooler, engine computer, dual fuel pumps, exhaust system, mufflers, and all accessories.
The reason I am selling it is because the package is not yet complete, and I would like to get my aircraft flying.
There are some people still doing development of the engine. The systems that will need work to make this FWF kit complete are:
New Gen III PSRU. The current Gen II supercharger that was shipped with the engine has been grounded due to several in-flight failures. I might be able to source one of these from another builder that has decided not to use his. A new Gen III is about USD 6000 from the Eggenfellner Aircraft.
Change out the supercharger for a turbocharger. The Gen III PSRU has a lower gear ratio, which allows the engine to rev higher, producing more power. A side effect is that the supercharger will spin faster than it was designed to. This can be resolved with a new supercharger pully, but I believe the best solution is to install a turbocharger.
Replace the Engine Computer. The ECU that is installed should be reliable, and many have found it works well. Some have had problems, and are switching to an SDS engine computer. I would recommend this change.
I really regret having to change this engine out for a traditional aircraft engine. I feel that the Subaru engine is an outstanding fit for aircraft, but I just don't have the time and resources to finish the development work on this package. The original supplier, Eggenfellner Aircraft, is no longer developing this package, having moved on to a 6 cylinder engine.
There is a yahoo list of about 25 other owners of the STI engine that are working together to finish the development of this engine, so I'm confident at some time in the future it will become a very viable powerplant for aircraft use. This list is called EggenfellnerSubaruSTI and is open to all STI owners. This is a good place to discuss this engine, and the development work being done from Australia to the US to Lithuania.
Please contact me if you have interest in this package (mick at rv8.ch, please include "eggenfellner" in the subject). If I don't sell it, I will pickle it, put it in the corner of the workshop, and when the development work is complete, I'll either put it on this RV8 or my next one! :)
I had my panel laser cut by a guy in Idaho recommended by the epanelbuilder.com website. I believe the price was pretty good, around USD 100. The problem is that the laser seems to do quite a bit of burning through the aluminum. I've attached some photos. I'd recommend going with a company that does water jet cutting instead of the laser.

This is part two of the battery rack in the tail story. When I went to put in the baggage floors and sides, which go in front of and on top of the area where I put the battery, I was rather disappointed to find that my beautiful battery mounts were interfering with the forward vertical part of the baggage skins. It seems I have mounted my batteries too far forward. Ugh!
To fix it I needed to simply move the batteries back about 2 inches, so that's what I did. Here's what it looked like when I started:
Here is the old battery rack with the new one. The green is the old one. I was able to reuse the angle for the new one. Notice that I've moved the battery contactors back.
Here is the final result. Several hours of work, and now the batteries are just a bit further back. That should help with C of G issues, at least.

Just getting started with the installation of the Trio Avionics EZ-1/EZ-2/EZ-3 altitude hold servo. http://www.trioavionics.com/ The reason I listed all three current models because I don't yet know which version I plan to use. I have only purchased the servo so far, which is basically the same for all of the models. Actually, there is an optional automatic trim adjustment system that you can get for the servo, and I have this option - just in case.
Installing the servo is normally extremely easy, but since I installed my batteries just behind the baggage compartment, the perfect location for the trim servo is gone. So, I need to find another place for it. There really is only one place that can work, just behind the elevator belcrank. There is plenty of room there, but there is no supporting structure to mount the servo. I'll need to make something.
Here is my first attempt at some structure for the servo. The problem with this configuration is that the bulkhead where I was planning to attach this is too flexible. Everything back there is very flexible, and you really don't want the servo to move at all, for two reasons. 1) the servo will not be as precise, since it has to try to figure out how much the structure is moving in addition to the elevator. Not good. 2) any kind of flexing of the bulkhead will eventually cause stress fractures. Also not good.
The only thing I could figure out to do is to extend the angle that is used to create the belcrank mount. Here's what I've got so far. This is fabricated from a piece of 0.125x1x1.25 aluminium angle.
Of course, I had to drill out the original angle. That was not too difficult physically, but mentally it felt strange removing something that had been installed as part of the quickbuild. I believe this will be a good solution, and it is actually lighter than my original idea, with the lightening holes.
I'll try to get this installed next weekend and see what we've got. It might be a bit long, so I may want to shorten it.
