Where are you going to get the Whirlwind worked on? The company has been sold off once already? What if it goes out of business, get sued? Prop shops will not work on it, even though the hub is a Mccauley. The prop has not been tested at all as far as I know, much less with modified engines (high compression, electronic ignition). Here is the Van's flight test data: http://img82.imageshack.us/my.php?image=prop200415me.jpg (Second one down is the Hartzell Blended Airfoil, the first is the good old C2YK/F7666. The WW 200RV is the second fastestest behind the Hartzell BA and a little faster than the old Hartzell. The Sensenich does good at that one data point 75% cruise. I disagree with the calculated 207.9 mph corrected speed for the sensenich; you'd lose a little more than 3 mph by pulling back RPM from 2730 to 2500 with the throttle, but still the sensenich, optimized for cruise, is 2nd or 3rd in speed. I will point out of course takeoff and climb will be less and also flying in cruise with either at 2730 rpm or with the throttle partially closed is not as efficient as a constant speed prop that allows independent control of RPM from throttle, ie manifold pressure. However for value and bang-O-buck, the fixed pitched Sensenich is a great deal, and designed specifically and tested specifically for the RV, like the hartzell BA prop is.) There is nothing wrong with Whirlwind its a fine product as is aerocomposite and MT, but any composite prop from a small boutique prop maker is going to be more....well risk. You can't beat the Hartzell or Sensenich for value and performance on the RV. Both these companies have MADE props ENGINEERED specifically for the RV. The other companies basically have generic props they sell, one size fits all. Also having large companies with combined experience of WELL over 100 years is a good thing.

My only other Van's ride prior was backseat in Mike Stewart's Super-8 (much fun). The rv7a ride was great. Thank you, Van's, for the offering. Some impressions: - On engine start, I felt like the plane shook a bit much. Reminds me of the recommendation to by Lord's engine mounts instead of the one's in Van's ff kit. Also makes me want to pay attention to any other detail which will result in engine smoothness. - We started takeoff roll from a taxiway that was way closer to the end of the runway than the beginning. We were off in plenty. Cool! - Same great stick response as on I experienced on my Super 8 ride. I can't wait to be flying. - On landing, the nosewheel shimmied. Makes me glad I'm building the taildragger. - It got dang hot in the cockpit by the time we landed. It's spring. It wasn't that hot outside even for Florida. Definitely going to check out those canopy shades. Notes on poking around the plane: - The wingtips I have don't flare outward as much as the demo model. Wonder why they changed the tips... - I thought Van's sent me some extra canopy frames by mistake. You get 6; you need 4 to build the frame. Dang if the other two aren't used on the tip up canopy. I messed up a pair thinking nothing of it, so crap now I have to place an order. There are several parts in the fuse instructions which ship with the finishing kit and vice versa. Annoying. - I noticed the rudder stops on the demo model do not match the one's that the instruction have you build. Interestingly, I had to modify my rudder stops to poke out more to properly restrict rudder swing, and my mod'd version looks more like the demo ride. I thought I had done something wrong, but I trusted the end result. I'll post a pic on my site later of what I'm talking about. - The rudder was a one piece unit, not like the 2 piece I built. Wonder why they changed it.

They offered the larger -9 (2piece) rudder free for kits already shipped & started shipping the -9 rudder with future -7 kits. I share your pain on missing parts. I can't finish the fit of the structure from instrument panel to firewall because of 1 missing part, packed with finish kit. Duh... I also wasted about an hour discovering what you did about the 'extra' canopy frames, but fortunately I didn't trash them 1st. Van, here's a thought: pack the fuse parts in the fuse kit & the finish kit parts in the finish kit.

I can't finish the fit of the structure from instrument panel to firewall because of 1 missing part, packed with finish kit. Duh... That's got to be one of two parts: the "hat", or the long rib going to the firewall. I learned -- the hard way -- that there's a reason they don't give you the "hat." You'd be tempted to rivet it on. Bad move since it requires the installation of nutplatest they don't tell you about and also you need to make a hole in it, which also isn't on the plans. I found that whenever the instructions say rivet this or rivet that where the subpanel is concerned, DON'T. The whole subpanel section should be in the Finishing kit instructions, not in the fuselage kit. There's nothing to be gained by installing it at the point in the instructions it exists in the fuselage instructions. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv7-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV7-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv7-list Browse Digests http://www.matronics.com/digest/rv7-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
