The stab drive is the only thing I am less than thrilled with on the Maxa. There must be a small bellcrank at the base of the fin with a drive rod/threaded thing that floats around at stab level. When engaged with the stab its rock solid. However, without something in the hole it floats out of sight and needs to be fished around for in order to mount the stab. I solved the problem with a small tapered wood peg that goes in as the stab disengages, and can be pushed in far enough for a friction fit in the hole. Then I retract the keeper as the stab is reengaged. Its a bit of a nuisance, but livable.

T- next time I come down I'll bring the big, fluffy plane.

Try a small super (neodymium) magnet on the side. Should allow you to slide/position the clevis where you want. Also hold it there when you store the plane. No more "fishing"

"mini" Maxa

Lots of discussion here on the Maxa. What about the miniMaxa (3.5m)? Has anyone experienced it? Any comments? How does it compare to the Supra pro full spread tow?

Yes, I know the big price difference.

Is there a lot of interest in 2.5M planes?

The small tips for the Maxa yield a span of 3.5m not 2.5, it is on Barry's site as well. Go Read Guys! Details are on the Maxa page, not sure about pics but specs aswell.

And ya, no one cares about a 2.5m span thing around here either.

OK, someone asked about a 2.5M mini maxa and I was wondering why they would produce it in such a high end full house package.

I don't know of any Mini Maxa in development. Maybe jpherit is confusing names with a new version of the Mini AVA Pro that Vladimir may have developed for KC. I saw some in production when I visited Ukraine in May, but haven't seen any completed models.

Folks, Just a simple typo. I am referring to the 3.5m version of the Maxa and am interested in hands on comparisons to the comparably sized ST Supra. I edited my original to the correct wingspan. I labeled it Mini Maxa as a tounge-in-cheek way to distinguish between the two models.

Videos are fun but they don't tell us anything.

What are your impressions either compared to the 3.9 bird or to the Supra Pro?

Not much time with either tip setup as yet but my first impressions are great. The 4 will be perfect for those early morning no lift rounds where you need to float. The 3.5 is more nimble and seems more forgiving than the Supras I have flown. My experience with Supras were the Pro light and carbon pro. No time on a spread tow Supra. As Joe pointed out you will need to ballast earlier than with a Supra. Over all the 3.5 is my favorite due to its handling over a Supra... it does have the same character of a Supra but will slow down better and it seems it will not drop a wing as quickly with an aft cg

Francesco helped us out with some simulations on the MAXA. This an excerpt from his findings.

"From my simulations it looks like it's a close match between 4 degrees and 6 degrees for the min sink setting. I don't consider the absolute sink rate value to be much significant, because XFLR5 doesn't estimate parasitic and interference drag, but just for the records it predicts it at 22 cm/s for a Maxa 4 at 1750 grams.
"
"I decided for comparison to analyze the Maxa at the same static margin, 8%, as my Supra, giveing a CG at 112 mm for MAXA.

More to follow and will be posted on our web site.
