I am ready to sell my completed and flying 2005 CH640. It has about 800 hours on it with a standard 6 pack, gns430, sl30, gtx327, dual VOR/gs indicators, superior xp-0-360 engine. It is a great flying ...

My tanks were factory built extended range tanks. To be honest, I never checked the thickness of the tanks and there were no markings on the sheet that I remember. I assume they were .025 per the draw ...

The senders I installed were the same as pictured. There is little guidance in how to install the senders provided in the drawings. I have enclosed photos of how I bent the float to measure fuel level ...

Well, I never thought I would be doing this, but circumstances have forced me to put my aircraft up for sale. It was completed in 2005 from a quickbuild kit, and has about 725 hours on it. I have all ...

Awesome Steve, thanks a lot that helps quite a bit. Looks like your finger got caught somewhere you didn't want it to! Ouch.

Yeah, probably finessing the darn sender in and out of the tank 20 times ...

You don't need a back plate for the fuel senders. Just tap the holes and screw it onto the tank. I used something called "sealube" from aircraft spruce on the tank fittings as well as the sc ...

One thing to remember is that the tank is isolated from the airframe electrically. The plans show a tab welded on the tank to connect a grounding strap to the spar. My tank did not come with the tab s ...

Here is a photo. The cutout is for the curved trim piece in front of the rudder.

I don't have the plans with me, but here are a few photos of how I did mine. There is a single bracket in the top center where both shoulder belts attach. Sorry about the large size, I can't change it ...

My panel is just like the prototype, which with a few tweeks is actually a good design. A hinged panel would be pretty nice if the longer instruments don't get hung up on the glare shield when you try ...

It is great that you are thinking ahead about this. While building you have open access to everything and it is very easy to forget about doing maintenance on the completed plane, which is completely ...

Christian,
My plane does have the change to the rear seat, moving it back about 4 inches. The way my plane is finished, 2 normal sized adults cannot fit comfortably in the rear seats. I do have prett ...

I'll throw in my 2 cents worth since I have over 700 hours flying the 640. While both the 640 and the RV-10 are both all metal 4 place aircraft, they are really not in the same class. The RV-10 is big ...

At least at the time I finished my plane, the FWF of the 640 was the same as the 801 except for the engine mount. So theoretically, FWF packages for the 801 could easily be adapted to the 601 as far a ...

Congratulations, I was wondering how the first flights went. Have fun and be careful.

Personally, I like the manual trim. I actually have the servo for the electric trim because they actually sent my kit with the trim bellcrank set up for electric trim with the servo installed. I took ...

Wow. Nice to see a small flurry of activity on this list.
Doug - Congratulations and nice job on your plane. It looks great. You will love how it flies. As far as speeds, here are a few ballpark num ...

I can't think of a simple or cost effective way to modify the design that would address this issue. I have no doubt that someone could design a complex system of weights and/or pulleys that would do i ...

Before anyone gets too far in adding springs and weights to your control stick, consider what most other designs have used in the past to increase the pitch force gradient; an anti-servo trim tab. The ...

So what do we know? We know that review of the design by multiple independent parties have found the design meets structural design parameters, both through computer modeling and destructive testing. ...
