 Posted: Sun Mar 09, 2008 9:04 pm Post subject: CH640 Performance Numbers |
 |
|
I'm new to the group here so hope this goes out correctly.
My understanding is that not too many CH640's have been completed as of yet. For those builders who have..... Can you confirm that you are really seeing 150mph TAS at gross with 180hp?
What kind of completion times are you all seeing on the quick build kit?
If you had it to do over again would you still build a CH640, what would you do differently?
My wife and I are hoping to get started on a kit this summer. Thanks in advance for your help.

I finished my 640 about 2 1/2 years ago. It'll do 130 kts TAS at gross, but I generally cruise at 125 kts. Other performance numbers are pretty much in line with those on the CH640 website. With 600 hours on it so far, I am happy with my choice and would build the same plane again. It took me about 750 hours over the course of 14 months to complete the QB kit and have it in the air, including paint. It's a relatively easy, straight forward build and the QB kit is well made and what has been done at the factory is well documented. I have plans to modify the cowl to close off some of that huge inlet and decrease cooling drag, but that will probably not happen until I have to have the plane grounded for engine overhaul someday. It's really in it's own class as far as experimentals go, intermediate between the common 2 seat designs and the heavier 540 powered 4 seat designs, with the sportsman 2+2 about the only comparable kit that I know of. So if your looking for a 4 seater that is economical and fairly simple to build and maintain I don't think you can go wrong.
