WOW! nice field!! how long is your runway?

Your mustang looks great! just make sure you put anything you can as far forward as you can, double-double check your balance point from the plans-add the weight that you need as far forward as you can, thats all you can do.

I made a form/box out of light plywood scraps, (I used CA glue) - inside dimensions of form/box was made to fit behind the spinner bulkhead, I melted enough lead to fill the form, let it cool, break away plywood form then shaved away to fit, drilled through bulkhead and into the lead, I used 2 small screws one for each side, screw in to test fit- makesure the screws pull the lead tight against the bulkhead, remove screws and lead and I applied Zap-A-Goo to the lead weight and re-screw to bulkhead.

My weight needed was about 1/2 lb. so it fit real nice behind the spinner bulkhead, now for 2 lbs. you will probley have to come up with something a little different, just try to get it as close to the front as possible, further forward less weight needed.

Just to let you know I had everything (batteries, receiver, on-board battery) placed were it was easy to get at (under the wing but forward), put it all together then balanced it, [X(]I needed alot of weight to balance, SO I thought "I hate too" -but- "I have to" - I took it all apart and moved it all the way to the back of firewall, saved more than I thought, Time well spent;)

looks good, you want to make sure your a little nose heavy (slightly) then you'll be good. I balanced mine upright which I probley should have done it inverted like your doing, but anyway's I had it sitting on the jig held it by the spinner in the level possision-let it go and it so slightly falls nose down. that's what I did, and it flew perfect I thought. I might try down the road to move the CG a little, but for know it works fine.

what's the 114.4oz? is that the weight it took to balance? tad over 7lbs?

51 looks nice!! did you get a overall weight yet with the lead you need to balance?

Hi willy answer to your qestion no 114.4 =ozs 1pound 14ozs balance weight. well moved every battery up front as far as possible . still wants to balance out 1pound 14.4 droped a little . must be rudder thats at the end of seesaw!!!! put nickel on it when balancing amazing what nikel will do to balance! well waiting for digital scale to arrive see what it weights .i used .056 glass z-poxie cut z-poxie 50% alcohol brushed thin layer on cloth sanded add light layer .well please keep writing to me if you get any ideas ok!t hanks willy

make sure if falls to the nose - charge it & fly it!! It will be fine!!;);)

build another rudder in the winter and re-balance then

let me know how the maiden works out. when are flying it???

Here my experience so far, Keep in mine here our very short grass runway is approx. 3-350' long, my first flight was with 0 wind and I had a to high of an idle w/3/4 flaps:( not a good idea, comes in way to hot! NOW the 2nd flight I had about 5-8mph wind much better/easier for the landing and I also set the idle WAY down this time, also w/3/4 flaps -- perfect landing!!;)

The take off - simple -(this is once trimmed out) if you want short takeoff (about 40') use 1/2 flaps, if you want a NICE long takeoff:D- use no flaps.
I'm guessin a perfect/realistic looking take off - use about 1/4 flaps ease the power up to about 70% and ride that baby out to about 300' and she'll be ready to Rock!!!! Well that's what the is plan anyways next time out.:)
Have only a couple flights on it so far, FYI it's a piece of cake to fly thou, at 1/2 throttle it flies very smooooth/scale looking like it should be!;)

good luck

willey!

Beautiful Bird!

My kit finished in monocoat, Robart's, G-45,
working inner gear doors, cockpit kit & a GI
Joe for a pilot came in at 23 pounds. This
is the one that I haven't flown in 5 years.

I always thought that if it survived a few seasons
flying, I would strip, glass & paint it. I have drop
tanks, too, but I haven't installed them yet. I may
do that if I glass it.

She's a beaut! Take care!

Johnny C!

next flight I'm planning to fly with the wing tanks so I'll let you know they work out.

HI WILLY YEA I THINK FILLING IN BETWEEN RIBS WITH BALSA ON RUDDER SO I COULD GLASS IT RESIN @PAINT CLOTH IS THE BALANCING WEIGHT FACTOR! WHAT DID YOU GUYS DO WITH RUDDER? IT LOOKS TO GOOD TO BE MONOKOTE!!!!! I DID MONOKOTE RUDDER ORIGINALY DIDN"T LIKE THE LOOK AFTER GLASSING 95% OF PLANE. WHEN STARTING THIS BUILD IF I KNEW WHAT I KNOW NOW WOULD HAVE EITHER MAID RIBS BELOW THE LEADING EDGE SO I WOULD HAVE ROOM FOR SOLID SHEET OF BALSA OR SOME OTHER MATERIAL !!i pretty sure this is factor with nose weight. i will let you know first maiden flight. Hey how hard was that canopy from areotec to install? MIGHT INSTALL WINTER . YOUR HELP HAS BEEN GREATLY APPRECIATED!! I THANK YOU!! WILL WRITE IN COUPLE OF DAYS WILLY THIS IS FIRST SEMI SCALE BUILD YOU KNOW !! I THINK I'M DOING A PRETTY GOOD JOB? WELL THANKS AGAIN!!BYE

F18, you'd never know that was your first scale job! looks great!!

you asked about the rudder, it's covered using the silk & dope method, and the canopy frame is homemade with brass rails mounted in the fuse, plastic i-beam mounted on canopy. The Aerotech canopy should work thou, just double check with aerotech on the width -because I think the TF fuse is wider (not as scale as the aerotech mustang). """I would love to own an Aerotech 51"""

Here's a couple other threads I started that might help you out also.

Questions/Issue I had with the Robart retracts:

the 3 rails in the fuse are brass "square" tubing (K&S brand) not sure off hand what size thou. The 3 small pieces on the canopy is called "Plastisrtruct" it's a grey plactic I-beam material that will fit inside the brass square tubing, you take a dremel tool w/grinding disk and cut a slot wide enough for the I-beam to slide throu. Be patient, It's alot of tinkering and figuring out, trial & error type thing.[:@] also the sides were cut down I believe the thickness of the brass tubing. Also take note the on the bottom of canopy has 1/64 ply glued to the inside to stiffen it, forgot to add that to the diagram below.

Hope this helps?
also study those pics in the other thread too!;)

[X(][X(]ACTUALLY!!! The Brass square tubing IS Brass "Rectangular" tubing not square

Hello willy /mark thank you again i will always give you guy"s credit for canopy design nice! WELL I HAD KS RECT; STOCK ON HAND SPENT THE WHOLE DAY MAKING RAILS I ALSO FOUND G-GAUGE TRAIN TRACK CUT A SECTION OUT ONLY HAD TO GRIND A LITTLE TO FIT WORKED OUT GREAT. WHAT A DIFFERANCE YOUR DESIGN ADDS TO THIS MODEL!!!! iF YOU GUYS EVER GET A MODEL TEC MUSTANG IT WOULD BE TAKEN TO NEW LEVELS .ONE MORE QESTION WHAT GLUES TO FASTEN THE PINS? THANKS FOR YOUR TIME GREATLY APPRECIATED OK BYE !!!

willey 09-08-2007 05:11 PM

RE: ????? Topflight P-51 85" What's Yours Weight????
 
Thanks F18, but this design has been used for along time by many others other then us, wish I could take the credit, but not our design.

As for the glue we used ZAP-A-GOO, this will hold anything on anything I think, got to be careful thou it might distort/melt the plastic, it very strong glue, test it on scrap piece of plastic first. It takes a long while to dry, so you will not see any effects of distortion for a while.

Also make sure you round the edges of the I-beam material so it won't snag on the box rail, it'll slide much easier that way.

this canopy project is very time consuming,[>:] but worth the effort.;) I think that's why you do not see them that much.

the rails have to be the same angle as the canopy angle (canopy is not 90*) look at the picture close - to see were abouts the I-beam is located on the canopy. It's set back a little from the front edge of canopy frame.

Also there is a small strip of styrene glued to the front inside lip of the canopy so when the canopy is closed the small strip goes under the front windsheild, this is a good idea to do, helps it from vibrating and sliding back and forth from side to side. Look at the photo above and below with the pilot, you can see the lip I'm talking about.

Last pic is just a teaser!!:D
