I've finished sanding the wing bones and am currently working on the skins. I know most of you active builders will have used this trick but for the new builders a method that will make your balsa skins look flawless.

#1 Using "Blue Painters Tape" tape your balsa sheets together. Make sure the seams are tight.

#2 Turn your skin over and place something under it to expose the seams.

At this point fill the seams with glue. I use regular Elmer's wood glue. (easier sanding)

#3 Lay your skin flat on a piece of wax paper and using your maxed out credit card you used to purchase your hobby supplies. (or you can use an auto body squeegee) Squeegee off the excess glue. Nice thing about Elmer's is its water based, so keep a wet rag around for cleaning the squeegee.

#4 Place a piece of wax paper on top and weight it down till the glue cures.

After the the glue cures remove the tape and sand both sides with a fine sandpaper. The idea here is to have your skin sanded smooth so you wont have to sand it on the model. (sometimes the ribs will show on the skin if you sand the model)

The pores of the wood on the side you squeegeed will be closed due to the glue. The taped side will be smooth and perfect. This is the side you want showing on your model.

So remember if you have to make a left and a right piece, tape on the opposite sides so both will have a smooth surface for your model.

OK thats enough of the teaching!!:o I need to get back to building.

Default Wing making progress

Here are some pics of the wing progress. Far from a finished product but coming along nicely. You'll just have to trust me its been a royal pain at times. The pics though don't do it justice, this wing has wonderful lines.

That'll be impressive hwen it's finished. I just finished the thread on how much you've spent on it. I wonder if I could ever get the guts to sink so much time and money into something and then put it 300 feet up

That thread only covered this past weekend. Thats why I said I'm afraid to add it all up.

Having enough nerve to put it 300' up isn't really the problem. It's having the skill to get it back down. I'm not there yet but hope to be by the time its done.

And I guess you can't really have a sim for that, either. At least with the months you'll put into it you know you won't get impatient and will wait for perfect conditions. My dad puts this level of workmanship into his model boats, but it's really hard to screw them up on a "maiden", worse case being wet pants and shoes from wading out. I guess a pack could light the thing on fire, but that's not so likely.

Good luck with the plane

Very - WOW! Nice job... I love building planes... I'll be watching this thread! How are you finishing the balsa sheeting? Are you covering it with monocote or similar covering?

Thanks,

I'm still looking for a way to 'harden' the balsa then I plan on using something like Flite Metal to cover and produce the rivets & panel lines. Last of course will be paint.

That should really turn out nicely! I'd love to build a large scale detailed model with rivets myself! I'll take notes from you!


I'm looking forward to the covering process =)

Default Fiberglass Specialties

The kit comes with a plastic cowl (4 pieces) and plastic oil coolers for the wing. Although the oil coolers looked OK I didn't really care for the 4 piece cowl. To remedy this I had Fiberglass Specialties make me a one piece cowl, the oil coolers and the dummy radial engine. They are the best, fast and good quality. I would recommend them any for any of you building a scale model or if you just nosed your plane in to hard and need to replace the cowl.

Heres the pics. For reference the Dummy Radial is 9 inches in diameter.
Note the open vents at the trailing edge of the Cowl. Just like the real thing.

Hey rea, in the picture that showed your wing on the bench in post 29, is that your JR sport in the background, because that looks exacly like my max66, and i have been wondering if they are the same thing.

Yes thats the JR Sport. I just recived my new DX7 today that will be used for this build. (and many others)

I've been awaiting parts to arrive to continue on the wing so it pretty much still sits as in the last pictures. I needed the Main struts/Door Cylinders and hinges/Servos/Pneumatic System/etc.

In the mean time I've started on the fuse. This is built "Top half" then "Bottom Half". Not a lot of progress (I just got started)

Update: The Main struts have arrived. With Wheels on the weight is 1lb 2.2oz each. I still need door cylinders (they are being manufactured now).

#1 #2 #3 Pics of the Main Struts. Yes these are "real oleo" struts

#4 Main Fuse bones nose---As you can see the Main Air Tank (pneumatic struts/gear doors/canopy) has to be built into the frame and is not removable. Except in the case of a major crash but we won't think about that.

#5 Main Fuse bones tail --- Not everything pictured is glued but as you can see this area will be built up quite heavily. All the controls (rudder/elevator/tail wheel steering) will all be contained inside the fuse. IE: no external control horns.

That's it for now I'll add more as I make progress.

Hi guys,

Not a lot of progress. I've been awaiting custom cylinders for the gear doors which has held up the wing and a cylinder for the canopy which has held up the fuse.

I hope to start today with covering the upper fuse but can only go so far while I wait for the cylinder. The covering is done with 1/8" balsa sheets so it should prove to be a little challenging.

Speaking of the canopy cylinder; Does anyone have any good suggestions for the rail system that the canopy will slide on? I've thought of several but haven't been able to make up my mind on the best way to approach it.

I know it seems odd to be looking at the Canopy at this stage with the bottom half the fuse not even started yet but once the skin goes on you can't get inside to make structural changes.

In other news the servos are finally on their way and the motor has arrived. (see pic)

At least while down on the build I've been able to get my MPXT converted to the new DX7 and I've also built a Slow Stick for some AP. If the weather cooperates I'll be flying them tomorrow.

Nice Double AXI!! "6.1, 6.2, 6.5 from the East German Judge...."

Just checking in to see how it's coming; I had to re-engineer the wing lock setup (the original design kept hanging up) but I see you decided not to do wing folds...well, I should have plenty of time to figure that out before I build mine! (In 2011, after I retire!)

I had the wing fold all figured out with the exception of the flaps. The fold splits between the 2nd and 3rd flap. Also I wanted the wing fold equipment in front of the cg and that was hindered by the landing gear mech. Splitting the flap drive would have also required another pair of servos adding more weight behind the cg. (there are 11 servos now)

im approaching my goal from other end designin my spitty to extrem light
and using much weaker axi 5360. 13kg is limit fo rmy plane ,its a hard goal.
but you dont have to worry about power for sure!!!
ill be watching your thread, so keep pics coming!!

This plane will have some weight to it so I wanted to make sure it had the power to overcome it.

Thanks!

The build has been on hold for the past month waiting on the cylinders for the gear doors and canopy.

I just spoke with them yesterday and they hope to have the fixture they need and be able to complete the cylinders by the end of nest week. Maybe then I can get back to building.

Robarts is now down to only one more cylinder to build. Time to get back to building this plane.

1. Pic of the Top Half of the Main Fuse (Bones)

2. Sheeting the top Half. -- This is a painstakingly slow process and I will supply more pics as I progress.

Thats it for today, I know its not much but this plane is starting to come together.
