Yes, it was.

You don't say Scott

Compared to our 7 and 8 builds, we are constantly amazed at the lightness of structure and the zealous methods for weight saving. That said, nothing has concerned us because once stitched together, the brilliance of design comes through with a strong structure or sub assembly.

I do draw the line somewhere though and finally launched the micro Molex fittings last night after testing with 'a light tug', the wire came out of the pre made crimp and left the fitting useless without a specialist extractor.

I tiny matter, but there are other niggles which I sincerely hope the 12iS will get rid of in a major overhaul of the instructions.

I guess when you improve and improve, it is difficult to keep up with a flow for building.

Back on thread, I did the fly off on a new 12 some years ago and felt completely comfortable at higher speeds - just before the canopy opened because the owner had swapped the catch round without telling me... It was a bit stiff he said

Once fixed, we continued and I was most impressed. The change to the iS motor I guess reflects Bombardier's ongoing stance with emissions and is a great step forward for a great aeroplane.

Customers have spoken and we have listened....

The new fuselage harness will contain no micro molex.
The connection at the pitch trim servo is being changed to a 9 pin D-sub

Back before I started my RV-3B kit, I got a demo ride in a -12. I remember it as being such a delightful aircraft, so well-behaved and fun.

Good luck with the new version!

I'm a great fan of the rv-9 but was disappointed to find the cockpit rails dug into my outer arm making it uncomfortable, particularly with a passenger.

Is the rv-12 any better? Wider? Or is the support structure at a different height eliminating the discomfort?

Thanks

The longerons are lower in the RV-12, and I think it's a bit wider than the RV-9A. It's remarkably roomy and comfortable for it's size.

The effect of the lower longeron, and the relative position of the wing, is incredible visibility - it's almost "helicopter-like" with the amazing forward/downward visibility.

Got some questions for whomever can answer them correctly. Some may be dumb, some may be obvious. Please consider the source and indulge me.

Does the iS engine still require manually scavenging the sump to check the oil level?

EarthX battery: Is a crowbar overvolt protection circuit included in the package?

Fuel system:
High pressure pumps (x2) rather than the current low pressure?
Engine driven mechanical pump? Y/N?
Electric pumps have fail-safe power source?
Why is the gascolator located there?
Is the gascolator up or down stream of the pumps?
How does one go about inspecting/maintaining the gascolator (at ACI)? It?s hard to imagine safety wiring the bowl screws through the access port.

Ref to photos by Tony T in his thread:
Can?t quite tell?are there screens to protect against FOD impacting the oil cooler and radiator cores? If so, will they be available in chrome? (?only kidding, only kidding!)

On landing gear photo, the wing root doubler looks different than the one in the SB14-11-03 mod kit. Is it? Why?

Retrofit. Call Van's today to ask about retrofit-abilty today. My fuselage is complete and just ordered the finish kit last week! (I think I am, or close to, the last RV-12 order).

Apparently, the fuselage is significantly different which eliminates retrofit of the fuel injected engine, fuel tank improvement, and other related features related. My guess is that the necessity of all the doublers (bottom of the fuselage and near wing roots) has been designed out as well. I just started building in February so I'm somewhat disappointed I didn't wait but hey, this thing is still the coolest kit build out there!

Would be happy if the stabilator tip could be retrofitted.

Stab tips already available.

Scott, I have the empennage kit currently working on the stabilator. Should I wait for the end caps to come out to finish it? How easy are they to install on a completed stabilator?

As for the the pitch trim connection, obviously I'm not there yet but my kit has the molex connector. Will the d-sub connector be available for existing kits?
