Default Kit

I do have to point out, they are selling it as a kit, not an ARF, alot of people get that confused. A kit, any kit, typically takes some TLC, I look at the minor discrepencies to be acceptable, LL is case in point for ordering his. At least it's not as bad as those foam chuck gliders some of us convert to RC, now that's sloppy.

I'm not sure what you're saying here...

Well, I spent some more time, building... See the pictures, below for what I've accomplished so far.

I hogged out some foam in the nose, for better access to the ESC area -- this way, you can remove the ESC, if necessary.

Looking at the pictures, you will notice some thread of different colors. This is so that I can pull the ESC wires through the proper holes, when the time comes to install the ESC.

One thing I noticed, when placing the tape on the wing spar (after glueing) -- the wing spar sticks out above the surface of the wing, when close to the wing root (fuselage). Did this happen to everyone? If I had not already applied the glue, I could have dug out the wing spar channel a little deeper... :o

After reviewing at the pictures in the last post, I realize I left out a few details:

1) I used a router attachment on my Dremmel tool to cut out a hole for the 0.5 ounce lead weight in the tail. The lead weight is actually a discarded automobile wheel balance I found in the parking lot at my local tire repair store. :o (Yes, I weighed it before installation, and it came out EXACTLY at 0.500 ounce on my scale.)

2) After routing out both sides of the fuselage, I put some Gorilla Glue and water in the area, and the weight is VERY secure in the tail.

3) I cut out a 40 mm square from a piece of 1/16" aircraft plywood. Again, I used my trusty router attachment on my Dremmel tool to cut a channel the foam between the battery bay and the cockpit. I was able to remove some foam from the battery side of that channel, and insert the aircraft plywood for reinforcement. This will allow the owner to move the battery farther aft (if necessary) to achieve proper CG balance.

4) After taking the picture of the ESC in the nose, I realized the servo wire passes right through the outrunner stick mount area. I plan to use a firewall mount for the Park 480 outrunner we plan to install. In the unlikely event we end up with a stick mount for this motor, I cut an additional path for the ESC servo wire, which will not interfere with the motor stick mount. If nothing else, these paths will allow better airflow to keep the ESC and battery cool, during flight.

Okay guys, I've put another 3 hours and 18 minutes into this build since the last time I posted.
1) Removed masking tape from fuse and wings. Glued C17 to wing leading edge. Glued Elevator stiffner to elevator.

2) Spackle fuselage and wing spar slot.

3) Glued horizontal stabalizer spar to horizontal stabalizer.

4) Cut out plastic cowl and plastic canopy.

5) Re-spackle fuselage, and wing spar slot. Also spackled tail surfaces.

6) Masked canopy with scotch tape and xacto knife. (See picture, below)

7) Re-spackle tail surfaces. Also spackled "landing gear pod" area. (See pictures, below. There was some kind of mould release mark on both sides -- very ugly, but it's fixed now. )
I think I may be finished with the spackle (though I might use a little more at the seams when I install the tail feathers). I will need to do some light sanding, but the "sanding and spackling" is just about done.

One thing that surprised me is there are two choices in the "under-wing" build which are not documented in the instructions... I have two pictures of the two parts (see pictures, below) -- one will allow landing gear, and the other does not. I have e-mailed the owner of this fine aircraft, and am waiting for his decision on how to proceed.

3 hours and 18 minutes? Are you sure it wasn't 19 minutes?

No -- it was 3 hours and 18 minutes. I'm keeping careful track of my time, as I am being paid by the hour to build this model. :o

It's really easy!
1) Start building models.
2) Post your work in on-line build threads.
3) Build a reputation as a perfectionist.
4) Get one of your models published in Quiet Flyer magazine (September 2006, for those who are interested).
5) Purchase a domain name, and start an on-line business.
6) Work for hours and hours on beautiful airplanes you will never own, or fly.
7) Work on airplanes late at night, work on airplanes during your lunch hour, work on airplanes before you go to work in the morning, work on airplanes when you COULD be flying.
8) Wake up one morning, and realize you're an old man, and you missed your kids' growing up, and you hardly know your wife any more...
(Okay, that last part was tongue in cheek. I do my best not to let that last part happen!)

LL,

It's not even that hard. You may remember this story from my RCG build thread. Last year when the P-38 came out, there was another earlybird member here that got a kit. As you remember, I had finished mine quickly and was showing it off to him. Out of the blue he asked if I wanted to build his for him. He used his connection with a certain motor/ESC supplier, and I was "paid" in two outrunners and 2 ESCs to replace the brushed units I had first put in there!

That's how it all begins! :o

Before you know it, you're ALSO testing those motors for that motor manufacturer... (It takes me about 4 hours to properly and fully test a single motor.)

I guess my point was simply that I don't think you ever really set out to do these things... You gain a reputation, and people come looking for you!

Actually, I had a few ask me to build for them. One guy wanted to buy one of my planes. I guess I thought they were just joking around. I rarely build my models stock, majority are fiberglassed with modifications. Here are three examples of my builds. GWS corsair with functional flaps and more scale control surfaces, the other is an ultrafly P40...both models use a single aileron servo with flex cables, so belly landing will not rip out servos.

GWS, PT-17 has mahogony cabanes that I hand cut with flying wires.

Hmmm...now I just have to get them published in that magazine.

LL, yeah I guess it does start that way. Although he hasn't asked me to build him anything else so far. BTW the "motor mfgr" was Hacker, and I'm pretty sure they do thorough in-house testing before putting anything new on the market. (just a friendly jab at ya )

Bandit, not long ago I got a PM from someone asking to buy the GWS A-10 I had just finished. I told him I only had 2 flights on it at that time and wasn't ready to part with it yet. Weird.

LOL -- I don't understand the jab... However, who's to say I'm not considered "in house" for this company (one that everyone would recognize if I were to say it here).

I agree -- those flaps are amazing. Also -- how'd you get the surface of your Corsiar to look so nice? It's fiberglassed, right? I can never fill in the weave good enough without adding 20 ounces to the model. (I'm exagerating, but you get my point.)

I don't have a full build thread, but I have a few pictures of how I set up the linkage posted on a different site.

Yes, it's fiberglassed. I get that smooth finish through sanding, filler, more sanding, it only added maybe 2oz in weight. Hey, I could build you one...I'll even give you a discount on my per hour rate.

Maybe I'll have to start a thread on the corsair flaps, I seem to get a lot of interest in that modification.

P.S. Thanks for the compliment Grasshopper.

Ok, now back to your build thread...sorry for the off subject chatter.

LOL -- it's okay. I'm not building right now anyway.

I'm at a point in the build where I don't think I can really move forward until I get the package from the buyer. He's sending the motor, servos, ESC -- you know, all the goodies.

Well, I will make you an honorary Monkey Minion if you create a thread here on that topic.

Then PM me the link.

Epyaya is showing the P-40 in stock already.

Yeah, but I don't think they REALLY have them... I haven't seen ANY at my LHS, and Tower Hobbies still does not show them in stock (I backordered one).

Then again, it is my understanding that Epyaya is "next door" to GWS USA -- so maybe they DO already have them...

Back to the build -- I worked on the battery hatch during lunch today... Just when you THINK you're finished with sanding, you pick up a random piece of styrofoam, and realize you have more sanding to do!

I must admit, the stock method of securing the battery hatch seems REALLY cool. I have to wait for the glue to try before I can tell if it really works or not -- but I can save a bunch of money on rare earth magnets, if this battery hatch deal works right...

Then again, I like the rare earth magnet deal because nothing is visible -- the new GWS method has a little black clip which is visible on the top of the model. No huge deal, but if this P-40 were mine, I might just do the rare earth magnet thing, and dump the stock GWS setup... (However, this would leave a small gap in the top of the fuselage, which would need to be covered somehow.)

No picture right now -- I'll take a picture when I have the battery hatch installed. :o

LL,

The new GWS method works great! It's now on the Fw-190, AT-6 and P-40 (the F-15 is more of a snap than a clip). However, if you ever do an AT-6, hit me up and I'll tell you the secret to getting it to work right (the nose of the battery hatch slides in under the cowling and is a very tight fit).

You can put those rare earth magnets away now.

Yes they do really have P-40s. Somebody on "the other board" has already received one from them. Epyaya does get new GWS planes much earlier than they show up elsewhere -- I got my GWS T-6 from them last June, yet the GWS T-6 still is not showing up at Tower Hobbies, or at a larger LHS in my area that gets new GWS kits when they can (for example they have the P-38 and Me-262).

Regarding the battery latch -- if it's the same clip as on my T-6, I like the system...except that after about 10 or 12 flights, I had a flight where it came off. I'm quite sure I had it latched. I was very lucky to find the battery lid, because I never saw it fly off during the flight, and only discovered it missing after landing. So now I fly with a rubber-band around the nose for extra security against losing the battery lid. It might have something to do with some upward pressure against the latch area because of the tight-fitting, thick 2050 mAh battery that I usually use.

Besides Epyaya, there is now another online vendor that seems to get GWS kits right away.

Caliber Hobby

This has not been confirmed, but we think this is the GWS USA storefront.
