:) In a last ditch effort, I covered up the wing and aerilon over the weekend...then last night glued up the aerilon hinges.....one does this first so one can insert vertically the assembly into the wing......will glue that up this afternoon...then I will have an official ARF...since we have a new format, I will use this opportunity to see how pics. work... Pic1 is just a quick shot of the mess one ends up with when you cover....wife will be please tonight as I clean it up....Pic 2 is a shot of the hinges in a glue mode...drying....

Did my thing last night.....finished up the last wing....now all done with the build....WOW....estimate is around 200 hours of total time. Next kit would go togetner much quicker as the learning curve would be past.

If I get time this week I will assemble the parts for a final pic. I appreciate all the interest received from all of you. I encourage all of you so inclined to build such a kit. It is a great feeling of accomplishment and also a pleasant experience. If I had any real exasperations, it ended up being in the covering of the model. Covering is a series of skills that I do not have....as work progress, the results generally improved.....as long as I participate in "stand way far off scale", I will be okay.

Once I get all the gear installed, I will post an update...until then will see you in various threads....V:)...one final pic of the wings.....

Out of curiousity, I weighed the last panel.....it came in at 50-ozs.....so two ounces more than the other....no way to evaluate how this compares with others...will do some more weighing of other wings to see how close this is. Since I did not weigh all the balsa, it seems to me that this is reasonably close....need to balance plane anyway....so time will tell...

A final build out weight can now be accurately projected..will do this tonight and post for those so interesed including a final pic. of completed plane.....V:D

Well, I went ahead and ordered up some parts and began hanging a few items. First hung the main gear and tail wheel assembly. Then went ahead and did a trial fit on the motor. After doing this, it became apparent that I had overlooked an important point on the cowl finishing....that being the 90-degree elbow that fits on the entrance to 3W engines...nuts..!!!! I have an interference problem and now must cut the cowl to clear the elbow.....this is a big deal as one must now seal off the clearance between the elbow and the cowl to prevent air leaks into the cowl....like I said,,,nuts....!!!!

The engine came with a plane we purchased and has been rebuilt. I already have completed the break in on the bench per specifications...runs like a monster and has unbelievable compression....so would like to use this motor....usually use DA's.....pic below shows gear and motor...

Well progress is slow waiting for some parts...almost all the parts are now in and weighed...total weight to date is 35.0-lbs excluding three items...these items are a pilot, a rudder tray of choice, and servo links for 14-servos....so final weight will be at/near 36-lbs for a 122-in. span model.

Will post a pic when the wheels and pants are on...moving on..!!!! V:)

Some stuff came in for the tank and wheels so in light of some recent ramblings posted on this site regarding tank set ups, I decided to finish up the tank first.

I prefer the three tube set up...more difficult to install, however, it provides a piece of mind and as always some downsides. On the up side, there is only one feed to the engine and two ties....ignoring the internal tank setup. Thus, as long as one does not run out of gas, the engine should always receive fuel. The overflow is a separate line....the feed and withdrawl is a third line. The one downside of the three tube set-up is that the feed-withdrawl tube is higher in the tank and will not remove as much fuel unless the plane it tipped up somewhat....I do not view this as a major detractor.

WIth a two tube set-up as one feeds in fuel, there is pressure against the fuel pump diaphragm which is apparenly okay...just not vogue for me....and of course if the closure piece(stopper) for the feed comes off or is left off, the engine most likely will cut off.

The key to installing the three tube set-up is in rotating the tubes after installation to get them into position....the ones that will need rotation are the vent line and the feed line......

Pic1 shows the complete set up using a PSG fuel cap..

Pic2 shows a close up of the safety wire ties...

Pic3 shows the clunk with a filter.

Pic4 shows all the confusion at the stopper....

WIth a little bit of patience and some expletives deleted, the unit goes in with a snug fit....if you are using large diameter brass tubing, make sure and do a trial fit of the stopper to the tank...I had to slightly enrlarge the hole to permit a smooth insert.....later....V:cool:

:)I have not found the barbs to be necessary with the proper use of safety wire. Past problems I have observed with others is with the use of plastic tie-wraps...which do not placed enough pressure on the tubing to assure a seal. If you will notice in the close up that the gas tubing is compressed and juts above the wire...trick is not to overtighten and then cut the hosing....just takes practice.....regards...V
