RE: RE: RE: more progress
Hey AJ,
Don't listen to Combatpigg, he is just trying to make your plane weigh more. Dip in paint indeed!!!
He knows the real method is to dip it in red coolaid and hit it with a hair dryer.
Then a light coat of egg whites and your done!!
For shame combat!!

RE: RE: RE: more progress
Well, I was pretty hot and heavy into electronics in high school, but that doesnt really interest me too much now... 
Wood and metal are so much more fun to work with!
After I walked my dog this morning, I did a bit more. Hope to get back in the shop after lunch for a few more hours....
I have the "crutch" done and the fuel tanks and servos set in, now I can close them up....

RE: RE: RE: more progress
A few more pics, after I have them pretty much finished. The entire top comes off with 6 screws to access the tank, engine bolts and servo.
Now I just have to shape and sand the plug for the cowl, and the windsheild.
And, just drill for my wing mounting bolts. Pretty much finished besides that - should start covering this week sometime....

Andrew,
That fine looking twin seems a little bit huge for these tiny engines... Don't u think it will be underpowered ? or are these flats amazingly powerful ?

RE: RE: RE: RE: more progress
The plane was sized for a good proportion between:
(a) engine power x2 relative to all up weight
(b) all up weight to wing loading
(c) for cosmetics, I wanted the engines completely cowled in
I believe the engines are capable of flying the plane. I stated before they put out about the same power as a Cox Babe Bee (a little less). I think I will have a power to weight ratio of at least .5:1, probably more like .65:1, which should fly the plane well, in a scale like manner.
If they are not capable of flying the airframe, I will simply install a pair of Cox .049's or maybe a pair of VA's or Norvel 049's/061's.
But I am determined to get even one flight video of the plane as built, with the .040 twins...

.However, my avatar never changes (the meerkat, a funny animal), which is more important, and a reminder of my initial name is located underneath (threads legibility).
For full real name, you can have a look at my profile
.Can't wait for the first flight vid (including sound pleeeeeeeeeeeeease) !!!!

RE: RE: RE: RE: more progress
Dont worry, there will be a video and sound as well, same as last year. Even if the first hand launch ends in a lawn-dart and total destruction, you will see and hear it
I am an optimist, and in my dreams I see it climbing gracefully out of the launch with both engines purring just slightly out of synch....
Actually the ONLY thing I am stressing even a bit about, is that I am not sure who I will ask to do the hand launch. All the years I am flying, I have allways done my own. I usually have a helper hold my plane for me untill I get my transmitter neck strap on and get a good hold on the plane. Years ago I had a fellow basically throw my plane into the ground, and since then I only do my own launches!
The trouble is, with this low wing, and extra wide fuse, and twin props, I will not be able to do this. It will take a 2 handed throw, and I am nervous since most people I know dont have much experience with hand launching planes...
I wish I could find a nice flat area to try a ROG for my first flight, and if the lakes are smooth and glassy, and I get a day thats not too cold in March with little wind (rare) I may try that route...
Oh well, thats not for me to worry about quite yet. Still have some work to be done!

RE: RE: RE: RE: more progress
HI AJC! Launch it yourself! Once you get the engines fired up, and a hold of it behind the wing, you will see that it will be no problem. It's too scary to think that you would hand it off to someone else! That thing isn't going to need much more than a gentle push to get going![X(]!!

RE: RE: RE: RE: more progress
Hi AJC,
I second CombatPig on the hand launch. My RV-7 is about the same size as your plane with a 5" wide fuselage that has tapered to a little over 4" behind the wing where I hold it for launch. With the Speed 400 motor it is just a lazy climb out. My RV weighs in at 22 ounces with a 223 sq.in. wing using a Selig S8036 airfoil.
After I finish my Sky Terrier contest entry I am going to build up a light weight version of the RV-7 for a Norvel AME .061. I will be making up the fuselage molds for the Sky Terrier this week and will probably layup a new carbon fiber fuselage for the RV at the same time.
BUT, your comfort level is the determining factor. That is too beautiful an airplane to take chances with.

Whoa! Somebody stop him!
Geez, Andrew, you are a MACHINE!! It took me a month of head-scratching and cussin' to get the Twin Lizzie nacelles built. GREAT job!

RE: Contest Entry for AJCoholic, a play by play...
AJ nothing else I can add do you have some time warp going 124Hr days?? beyond
belief engines, heads,and now this plane. ( if the rest of you folks have not yet checked
his diesel site posts do it)

RE: RE: RE: RE: more progress
I am thinking about that, but he has no experience other than hand launching his many rubber powered models... but he is keen and would probably do a great job...
I wasnt going to post yet, but since I am here allready...
Started covering the airframe last night. I wont post pics untill its all finished. I also formed my windsheild, and am working on the cowling plug...
Stay tuned for more later this week....

RE: RE: RE: RE: more progress
OK, here are some more pics...
#1 is the plug for the windshield and the windsheld after I painted it.
#2 is the cowl wooden plug (black one), the mold I pulled off it, and a rough cowl, and one I started to trim up and sand. I used west system epoxy, white microbaloons and some 3/4 ounce glass cloth. They are light, yet very stiff. I thought it would be better than vacuformed plastic from a longevity standpoint.
#3 is the semi finished cowling on the nacelle...

RE: RE: RE: RE: more progress
WOW! Those turned out GREAT!I'm still tossing a coin about going with plastic or glass for my bipes' cowl. I guess styrene is what to use. The bipe has a relatively huge [but simple] cowl. The little rolled edges on your cowls turned out SUPER! Make lots of spares, because you know that RC COMBAT is rough on equipment!

RE: RE: RE: RE: more progress
I have a confession to make, anyone who does anything better than me I hate.
AJ, I DETEST YOU!!![:@]
Your seneca rocks, and therefore I feel compelled to do so.
Just jokes, nice work on the cowls, if you don't mind I'm trying to figure out a layup that I need for 1/2a cowls what layup were you using?

RE: RE: RE: RE: more progress
I like to add microballoons to the resin to (1) lighten it (slight loss in strength isnt an issue) and (2) to aid in seeing how much and how thick the resin is, as West is so transparent, like water!
I have fererishly been working on the covering here at home tonight... I have a few more evenings to go, and I dont want topost pics untill its all covered.
I am using white and maroon monokote, and black pinstripe.
Its starting to feel "heavy" but I will not panick untill its all put together, and I take it to the scale for the last time.....[X(]

Man, I've been away for a couple of months getting into electric helicopters.. Just when I think I am done with airplanes for a while, I ran into this thread.. THIS IS AMAZING! This is like fuel for the brains of all of us 1/2a builders!
OK, all jokes aside, when are you gonna make the super Ace Whizard with a 1/2a rotary wankel engine made out of Cox BlackWidow parts?
I think I'll charge up my airplane radio and get everything ready for this weekend, I've suddenly got a hankering to fly airplanes!
