Ron,
Sorry to hear of the lose of your friend. Never easy to deal with, but sometimes it allows us to pause and appretiate the things that are important to us.
Hope you fell better soon, the F18 will still be there patiently waiting.
If it were me I would spray the surface with some hairspray, then carefully glass it.
Seeing as your surfaces are all solid (vs. Balsa sheeted open surfaces) you could also apply the cloth with a waterbased polycrylic. Sealing the balsa first is what will help keep your weight down.
The other optin would be to use dope (can you still buy it?)and silkspan. Its like a tissue paper that makes a nice light and fairly strong finish.
If go with cloth, you mix in some talc powder or micro spheres (not micro balloons) to your flow coat it will help fill the weave and make sanding easier.
Just some thoughts.

Smoe of the pattern guys and of course the control line stunt folks use .2 oz carbon veil attached with dope. Supposed to be just a fraction heavier than film, but it offers a stiffer control surface and a substrate for paint so everything matches.

Sean I did the wings on the mav kit I was building with the hairspray trick. I also used 100% polyester to act as peel ply and the wings came out very light and they only needed some sanding and light filling. I got to skip the whole filling the weave step

The monocoat thing will work also but make the plane a stand off scale plane.

Thanks guys,
All great ideas... I'm not really sure yet. But I'm going to talk to my dads painter about doing the fuse and some small parts.

I was thinking I could get the hatches fit, do some body work and priming...then take him the fuse.

While he is painting it I'll finish the wings and stabs.. get them covered in monokote and servos in.. paint my landing gear. When I get the fuse back there would be very little left to do.

I will glass the vertical stabs as there is a seam I have to fill

I'll have the body shop mix the paint to match the monokote well

I like this idea... it will be light, easy and faster...
I'm not going to compete in scale for me this is just another plane to fly

I'd like to see how much performance I can squeeze out of this thing.. I don't want a flying dog.

I dont blame you. I have considered many time just building the wing for my JHH A-4, monokote and move on with it just to get it flying.

Another though is that the splitter are on standoffs??? If so, glue some steel plates or magnets on the inside of the fuse, and put magnets on the standoffs so you can throw them on there for static display. That is the only time you will ever see them anyway. Can see them at a buck-30 3 foot of the ground!!

Hi Ron,
I noticed in the first post you spoke with Thomas about the carbon fiber plates. Who did you end up ordering them from? I'm ready to order those.

Basically done short of installing a power system and four servos. I lowered the mains by 1/4" and it made all the difference in fan clearance and duct install. Once fans are in I can see where to put the lipos to meet CG. Will do a mock set up soon based on expected fan weights using either SeanEmax/RonEmax/Tam's coming fan or DS94s. I am a little concerned with the 16 lbs expected installed thrust of the Dynamax in mine as it will be heavier than your expected weight. There will also likely be some losses due to inlet ducting so worst case may be 15lbs each side as a ballpark guess and I could be wrong. I'm looking at about 45 lbs RTF. I'll have to take a few weight measurements of components like wings and horizontal stabs to see how those weights compare to yours. I'm having a lot of fun with this project even if it's slow going.
Carl

Carl,
ACP has some solid carbon laminate sheets on clearance right now that would probably be worth-while in picking some up just b/c of how cheap they are.

For instance,
a .110"x8"x16" sheet = $33 when they are normally $65+

Thats great Carl... you keep pluggin along
Health issues over the last couple months have kept me out of the shop. But I'm feeling much better and started working out there last night.
I really want to get moving on mine, when I do work on it it goes pretty fast.

I ordered 1/8 carbon birch laminate from dragon plate. I used a 12 x18 piece I believe... and still have a small piece left over that I'm going to make new lighter vertical stab spars out of

http://dragonplate.com/ecart/product.asp?pID=484&cID=29

keep pluggin along... I can't wait to see them both done. I wonder how simons is coming? EDF nut... his looked pretty close also

later bud and post some pics!!!

Thanks bud... nothing that is life threating. I'm just lucky enough to have several on going issues that come and go. One is two bludged disk in my neck. When I tweak it, it can go out for months. Really painful and makes it very hard to bend my head over for long periods of time... I blew it out in early January. But it is feeling much better.
I also had acid reflux do a number on my throat.To the point where it felt like I had a sharp piece of glass in my throat and I couldn't talk. I went through most of January writing notes and not talking. It was very dry and itchy so the last thing I wanted to do was sand balsa wood My doc was having a hard time getting me meds that would help.
I went to a specialist and they have it under control now and it's also feeling much better. So now I'm in voice therapy and a trainer to help my with my neck and over all excercise....been a long road

In short I just took a break the last two month from R/C to work on myself. I'm really feeling much better and looking really forward to the project... I flew my park flyers this weekend which was the first thing I've flown in awhile and it felt great!! very exctied to get back to it... I'm going to start slow, I can't mess this neck up again.

Without your health you have nothing that is forsure
very excited for the coming season and brighter days! haveing R/C to look forward to really helped me work through all this

We are all in this boxing ring called life and it's nice to have friends, family and god in my corner

Using JR ds8411s in the wings my wing weight per wing was 1lb 15oz w/o servos and 2lbs 4 oz w/ 2 servos and one 12" extension. 4.5lbs tied up in the wings. Should fill them w/ helium.
