I think that getting the aileron differential correct will be more important on the longer winged plane.

Mike and Clay,
I had this very converstaion with Philip Kolb last week. He reminded me that tail moment is a linear measurement and adding tail dimensions increases the volume by a factor of square. So his view was that it is easier to make bigger tails to increase stability. I reminded him that more squares means more drag. In the end I believe in a longer fuse moment arm and really think the Aspire handles as it does because of the longer fuse. It then of course becomes the issue of shipping these models that have large dimensions....new boxes to follow. All my best Mike it looks like a nice model. We are all watching for the coming 4.2 meter models. Larry

Hi Larry,

Thanks for that....there ya go, guys; somebody who knows something about aerodynamics and can speak with competency. Of course, Larry just mentioned 4.2 meter birds....OMG! 165 inches of wing! (And I used to think 118 inches of wing was pretty big!)

Thanks!

Mike,

Beautiful paint job!! I should have my Xplorer sometime next week. I know this means extra effort on your part but could you post pictures of your build, especially 2.4 radio installation, on this site? It would mean a lot to some of us who are doing an Xplorer build.

I'm having 2.4 range issues on my Eraser and Condor and would like to see how you do yours on the Xplorer.

Thanks in advance for any information.

Phil

just like lego!

Mike - I make only one assumption - can you here please confirm sir?

The new wing design is the combination of the new tips and new stabs. The center panel is unchanged correct?

I wont begin to speak to the technical attributes of this design.

It does seem that things have been well thought out with a longer fuse for the current wing. That may have been intended for this end design (3800). Now if the handling turns out to be great what you have is a bunch of options for parts ordering. Standard wing/3800 and stab. That's a very smart marketing move if the 3800 flies well and I have no doubt that it will. I think it will drive parts sales.

Mike,

What did Larry say? This is my take : to design a larger ship you have a longer fuse like the Aspire that handels very well. To add larger wings to smaller fuse and FIX the handleing issues you make larger stabs.
Each designer has there opinions but I am interested how yours works out get it going

On the other hand you have a lot of guys that purchased Explorer
A very successful design with many happy owners
BUT they now have a old version ship or lay down more $$ to get current?

It's like, do you go for Vista or stay with XP OR just go get a Mac

Get a Mac :-) I'm wondering what these birds are going to do to standard club winch equipment. A regular (no extended tips) Perfect can stall a winch, in fact, even my Icon can bog one down pretty well. Probably need 400# on the down line, and 300# on the up line.

Mono and F3J tows are a different story. Still going to stop some towers in their tracks. Can you imagine towing a 4.2 meter plane in a 10 mph headwind?

Mike, also very interested in how she handles in the landing zone. I'd think if you were all lined up it would be easy but if you get out of shape corrections are going to be slower.

Phil,

Okay, I will post what I can on the build. No magic stuff...my builds are pretty common stuff to all people.

Webb: I am assuming you do not own an X to know the dimensions. Okay, here is the stock original wing dimensions.

Wing center section: 56 inch

Outer panel: 41 inch

Hor. Stab span: 14 inch
I hope that helps.

Smokin Joe: Don't care what LJ said...I admit I don't understand all that and my point was that there are people who know one helluva lot more than me...like LJ. So, I don't get into this type of subject matter.

Big John; I can tell you that anything that can go this slow on approach is going to be subject to being blown around a bit. I know my light one gets it, but it also responds well to the rudder and makes a good correction. If not for that, it might end up in the weeds fairly often. My normal X is more steady due to weighing a bit more, but then it doesn't get as slow on approach, either. It is slow, but not as slow as the light X.

Guys looking for the build, I ask for just a bit of time as I complet another project more related to what I do for the publication I write for. Deadlines are important. As soon as it is completed, we will get into the X-3800...promise!
