Please correct me if I've heard wrong. At 2600 a copy I want to make sure its worth the value. Not just a plane to fly the first round and put away.

You will be seeing one flying with you very soon Joe. You can make your mind up in person.

OK, here goes (with comments):

In alphabetical order:

1) Aspire (No further comments necessary. It's what I fly)
2) Icon2 (haven't flown one, but I've seen world champ DP fly it plenty)
3) Maxa (only have 3 flights on it, but looks like a winner)
4) Tragi 801 (stiff, strong, light, well built, a TD machine)
5) Xplorer 3.5/4m (flies good and best bang for the buck. 234,201 Xplorer pilots can't be wrong. OK, there's a lot of them )
6) Zenith 3.7 (thermals like a homesick angel)

If one were going to add a couple more, you'd have to add the Supra and Perfect. But the above 6 are more in tune with my flying style. There's probably a few more that can be added to the list, but I don't have enough first hand experience with them to judge.

1) Launch altitude is sensitive to launch setup. Same as on any other plane. I don't have much time on mine (actually, it's Larry's, but he's not getting it back till after the TS) but I haven't seen anything yet to indicate a problem.

2) The Supra has a lot of flex also. Yeah, it looks scary. I've seen DP and Burnoski launch their Supras with our world class towmen at the 2008 W/C and bend the wings to a "U" shape, but they launched to the moon and didn't break the wings. Being that the Maxa is built by the same guy that builds the Supra, I would expect the same flex. I would prefer a stiff wing like my Aspire, but if you want light weight, I guess you'll need to subscribe to the fishing pole theory (flex is better than.....you know what). You Supra drivers out there won't be surprised, but the flex does get your attention if you haven't seen a real Supra launch (tapping it up on a club winch doesn't count. I'm talking pedal to the metal, on mono, in the wind). I think the flex has some "non-Supra experienced" Euro-pilots backing off on the launch setup, resulting in #1 above. For a plane that I'm sure will be unbeatable in dead air, I'll take the flex just like the Supra pilots take the flex.

3) Barry had a battery problem (when are you guys gonna take care of your batteries?) at the NATS and his went in vertical. I mean like buried up the the LE, and they had to dig it out. LE forward pretty much undamaged. Broke the tailboom. Stabs unscathed. I didn't ask Barry how the wings came out--probably totaled, but that is to be expected. If your dork landings are somewhat better than this, I don't think it will be a problem. I wouldn't consider the Maxa any more fragile than any of the other light sailplanes. You guys are all so bent on having the lightest planes, well you're not going to be able to just fly a sloppy approach and dive it towards the spot. You gotta level the wings before you push. If you land crooked, you're going to break most any plane.

4) I just copied my Aspire program and renamed it "Maxa". I set the launch flaps and camber settings to what I have on my Aspire and called it good to go. Haven't really changed anything yet. I know I need to tweak the Diff and Rudder mix a bit, and change the flap-elev comp a couple clicks, but it's no different than any other high performance sailplane. If you're having problems, bump the CG forward a bit. Larry had it at 103mm, but I think it will end up around 98mm for "happy landings".

I'll know more after I get more time on the plane. I'll post setup numbers when I'm done playing around. Right now they're the same as my Aspire and I don't expect to have to make much of a change to anything.

Hope this helps.

Right plane, wrong year. The Esprit was on my list in 1997 (when most everyone else was flying obechi sheeted wings and a few bagged wings) I wonder what another 10 years will bring (besides me going totally gray....and that's best case scenario)

Dr. Kaos,

I just finished one. I have the CG at 107 which is quite a bit forward of where the X tails run (~120mm). The wing is set up per Tuan's specs in the Xplorer thread and I can measure the tow hook for you if you need it. PM me if you are interested in more.

Yo can start as far back at 110 but 107 is very safe...- I ended up at 115 on the V-tail

Stick the hook in the middle of the slot and start moving back a couple mm at atime. I ended up almost as far back as I could go with maybe 3-4 mm left.

Aaron,

Hard to find any appropriate data in the Xplorer thread as it is soooooooooooooooooooooooooooooooooooooo long (and covers so many other topics!).

That thread needs a moderator to parse the thread into maybe a dozen topics of discussion...

Sorry for the foul Aaron. Just trying to answer the question while I eagerly drink up the Maxa information!

I think the Xplorer thread is now the "sailplane general knowledge" thread. Just need to rename it

The Xplorer thread is just that, "you explore the thread looking for information you'll never find, but find information you would never look for!"
