Thanks Evan.

Well I went ahead and made some frames for the race car. I put one on either side of the transverse cut location and one at the aft end. Then I got the dremel tool out with a thin cutoff wheel and started cutting. I laid out the cut lines on masking tape first which kept the gelcoat from cracking.

I made up some balsa blocks with magnets to hold the two halves of what will now be the center section on either side of the main rotor head together. I will have to relocate the lower magnets when I get the mechanics situated but I wanted to make sure everything fit back together properly. I was nervous about cutting the fuse but I think it turned out well. I took my time and made sure the new frames held the pieces it the correct shape. I will be attaching the frames with hysol as they are just CA'd in place right now.

I'd be happy to do that for you Butch as it would be the least I could do for all the help you've given me. But I'm pretty sure you will do a better job than me when you get around to it!!

Today I decided that I wanted to cut out the luggage compartment doors and make them working hinged doors and I will add some scale detail in that area as well. I have major support fore and aft of the doors and I reinforced the door before I cut it to hopefully keep it from warping. Here are some photos of my work.

and here are some pictures of the full scale detail in the compartment.

I hope everyone has a great Thanksgiving with family and friends!

Thanks Sean.

I am really enjoying this build so far. I have to admit that I was pretty intimidated by it before I started, which is probably the main reason it sat around for almost two years but now that I've really started I'm really getting into it.

I emailed both the FBO's at Brown Field in Atlanta Fulton County and at Houston Executive Airport regarding the full size subject. the FBO from Atlanta replied really quickly and said he wasn't familiar with the aircraft and that it wasn't based there. He also confirmed that Wells Fargo is the lending institution not the operator.

I haven't received a reply from Houston. So if anyone has any other leads or ideas please let me know.

Looking Good...

You are in the deep end of the pool now, and looking really good... no doubt it will be a beautiful machine when you get it finished..
Suggestion., post in the main forum, looking for scale info, and put a pic of the subject heli in your post... never know who will be looking!!
And, Have a Happy Thanksgiving!!!

OK so for my first attempt at installing the baggage compartment door I cleaned up the edges and used some rubber window trim to fill the small gap.

I thought it looked pretty good and was proud of my work. But I was quickly schooled by an expert that I had it all wrong! So here is my second attempt. It took a lot of time and I still need to do a little more finishing but in the end I think my efforts will be worth it.

I used a poly flex body filler that is used to repair plastic car bumpers. The cure time is short but it sands easily and remains flexible.

So the first baggage door took a good bit of sanding and fitting to get it took look right. I probably spent about 4 hours trying to get the gap between the door and the fuselage even all the way around.

On the second door I decided to try something different. I wrapped the edge of the door with a few layers of fine line tape then taped the door into position and filled the gap with poly-flex. I then sanded it smooth to the fuselage and presto I had a nice even gap all the way around.

Once the door surrounds were complete I started working on the hinges. I used a set of gear door hinges that look similar to the full size and should allow the doors to open to a little past 90 degrees. Should being the operative word here. I took me a long time and a lot of trial and error to get them right. This was the first time I ever install hinges other than the surface mount ones that are on all the rest of my scale ships and I soon discovered it was a real challenge. Everything had to be lined up just right to allow the door to first clear the edge and then be able to open far enough without hitting the side of the fuselage. I eventually got it...

I also installed small magnets at the two corners opposite the hinges to hold the doors closed. I will next be working on trying to make some scale looking latches for the door. So if anyone has a good close up photos of these and can share them that would be great! Hint, hint Butch

Nice job. It won't be long before I am cutting doors out, too. Good idea for filling the gap. I don't have that issue with the 500 doors as they overlap the body, but if I make the engine compartment doors open, that will be a very good solution. Take care.

Here is latch #1. I have a little cleanup around the cut out to do but I think it came out OK.

Usually when I make something a second time it comes out better than the first so we shall see how the one for the other side comes out. If its better I will probably be replacing this one.

Finished the latch on the other side. Here are some photos that show how I made it.

Ok I switched gears here and started working on something completely different as the filling and sanding was getting a little tedious.

Right now I'm using styrene sheet and I plan on building up the part in layers if that makes any sense. This is the top layer and lower layers will fill the center sections of the arms in.

This is one of two main rotor bifilar vibration absorbers that will be mounted on the top of the main rotor head.

Andrew, that's really cool. It will be something to drool over when it is finished, that's for sure.
