Look at the twin-sync. Sold thru RC Showcase.
Apart from a glow driver, consider some risk management if you should loose an engine.



Well Mike i am aware of twin-sync system but realistically i want to keep my engines running all the time instead of leaning towards losing them and then going with twin-sync route.

So, , , , , ,what good is a glow driver if an outboard glow plug simply burns out at 50 feet?
Make sure there's a strong servo, and enough travel on those rudders.

Check glow plug every 2-3-4 flights and if seems faulty changing them right away would be the best way to keep all engines running at all the time, it would be a small on going investment that could save thousands spend already on the model itself....

Btw i am not saying anything is wrong with Twin-sync system also, so don't take me wrong here, i just want my engines running all the time..



Mike Emilio -> RE: Scratch building 105" W/S Super connie L-1049 G (9/16/2007 4:00:15 PM)

I bought this for the B17. Brand new, everything soldered up ready to go. Same price I paid. Let me know if your interested.



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (9/16/2007 9:39:31 PM)

Mike,

Give me a call, i like to know more details about it and let see what we could work out.



flysrc -> RE: Scratch building 105" W/S Super connie L-1049 G (9/20/2007 7:09:00 PM)

Sammy,
How is the Connie coming? Any progress of late, I know it is flying not building season but I've been following this for awhile and want to see more.

Hey Dave,

Nice to hear from ya mate. Connie is sitting in storage at present, i had very rough summer due to severe health problems relating to last year's accident, i haven't done anything on it for months now but now i do plan to work on it and get it rolling once again. I will be glassing it soon but prior to that i will strip plank all 4 engine nacelles/pods as that have to be done before i glass the wing structure.




Eagle 999 -> RE: Scratch building 105" W/S Super connie L-1049 G (9/24/2007 9:55:43 PM)

Hi
Here comes a Nice Connie

www.aerobel.de

Greetings



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (10/17/2007 7:34:46 PM)

Well i seems to be out of loop now days due to health problems, but now i can put them behind me and look to great Connie building future. Since last post lots of work have been done to the model, unfortunately i don't have internet assess at home currently so i have to come to public library to check on stuff, due to this no pictures could be uploaded but i will mention work done so far.

No glassing done as yet but work has been on centre wing section. Firewalls were reinforced, Landing gear rail formers was cut and installed in both inner engine pods, rails were cut and made from sig hard wood fixed gear blocks and installed in the pods. right inner wing recieved leading edges, i used 1"x1/2" stick of medium balsa to make them. All 4 engine pods are currently recieveng strip planking to make outer skin structure of the engine pods!, man this is one slow process, takes too long but results are rewarding!. someone should come up with another method for strip planking the engine pods.

I had to cut 1/4" x 3/32" 4 foot strips from the 3/32"x4" sheet, then i had to cut required length of strips and many of them for different areas of the pods. I am using GP Alaphatic resin (Pro wood glue) for this application. I also had to make fuel tank access hatches in the outer pods, this took some mind bending, unlike other areas!....

So far project is coming along.



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (11/16/2007 7:24:49 PM)

Project is countinuing at very good pace now, i was at the Canada's Largest Hobby show couple weeks ago with my model demonstrating guys how to glass the foam sections of the model, i actually ended up glassing almost whole tail plane at the 3 day show and it was excellent. Lots of guys saw what i was doing hands on and asked all sorts of glassing questions, i also learned few things from the guys who have done this sort of job before.

Since the show i have glassed the whole fuselage and it turned out really good!. I used 4 oz and 6 oz cloth cut into wide strips and Aeropoxy epoxy resin for this job. Initally i was thinking of doing it in 5 sections but ended up doing it in 4. Top, both sides and bottom sections.

Last night i started to make rudders out of balsa stocks and sheeting to save the weight in the tail plane, so far i have built left outer top fin's rudder and center fin's rudder, i will be making right top and both bottom outher rudders today.

I am looking to get custom nose gear strut made for the model as there is noting long enough i can find for my application for this scale.

It was a surprise to me that there was a lots of interest in people, few guys wanted to buy this airframe from me but i refused them, i want to finish this one off and fly it. Once all the bugs are taken out and it performed up to my expectations then i will seriously consider to make short kits for S Connie L1049 in this scale for anyone who wants it.



aerowoof -> RE: Scratch building 105" W/S Super connie L-1049 G (11/16/2007 11:18:55 PM)

how about some pictures,as for the nose strut shinden machine or sierra may be able to help you out.

Hey John,

Nice to see your post on here once again....[;)]

I would love to add pictures as i have taken quite few but i doubt that i could add them on through public library PC. I will if i could, i will re look into it. Yesterday we had temp in plus so i took advantage of it and water sanded the whole fuselage out side on my driveway. It's looking sweet now and taken totally different prespective on the model.

Once inside i restarted to work on making rudders!, to my surprise when i dry assembled the tail plane on the table, outer rudders were off in chord lenght!, i made mistake on my measurements and missed it by 3/8" of inch!. No big deal, i just added 3/8" fillet on the L/E part of the rudders, now and they look sweet and perfectly aligned. Then i did same mistake on lower rudder couple days ago and made the whole lower section as rudder vs as lower rudders have fixed section of structure attached to H Stab before rudder starts. Other then these baby errors constuction is coming along pretty good.



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (11/28/2007 10:48:20 PM)

Ok its my fault i forgot to bring floppy with pictures to add on here!, not used to using/caring floppies anymore...

As the build progreses elevator foam surface area have been cut to replace with built up ones, so far i have almost completed one of the two elevators, just need final sanding but other one still needs ribs to be added with skinning.

For last 2-3 days i have been working on the centre wing section, all the strip planking is now complete with all four engine pods sanded to prefect round shape. Now all i have to do is start glassing the top of the centre wing section. I am waiting to get wing joiner tube sleeves to be made for both outer wings, once this is done and installed in the wing sections i will then do channeling for the servo wires in all 3 wing sections.

Fuselage is still waiting to get high and low areas filled with silica and resin combo, then i will prime it and may paint the top section white while my brother finishes the art work for TCA stripes to be added later.

I have decided to get Trimjet retracts for my model, these are bit more pricy then Behotec but i feel these are alot sturdier and constructed stronger.

Since i want to do metal replication on this model either by using flight metal aluminum foil or something similar, i will try and practice to use aluminum duct tape on my B-25 and see how it goes, if it resulted to my liking then i will use it on this project also. If anyone can give me tips on using duct tape this would be appreciated.



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (12/21/2007 10:39:51 PM)

Here are images from last month's hobby show where i did demonstration on how to apply fiberglass on the foam structure. I used Aeropoxy resin for this type of glassing. You can see parts being worked at in the back ground on the table. These are large 1MB images. I will be posting more images of current stage shortly.

The Connie looks like its coming along nicely. The tip tanks seem like they may be a bit large, It may just be the angle of the photos. I have pictures of the WV2's on Midway island if you need some reference.
Going to share your glassing tips with us?
KM



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (12/24/2007 7:12:46 AM)

Aure moody what would you like to know?. I need exact diementions of actual nose gear to make custom gear..

Hi Sammy, if it´s helpfull to you, the tanks were 18 ft 8 inches long and the diameter was 40 inches. I found it in the new books from Peter J Marson.

Frank



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (12/27/2007 5:00:35 AM)


Gee thanks Frank!, I
Have been looking for diementions all along
With out any luck from the begining off the project. Now will have to redo tip tanks as present ones were made by eyeballing.

Frank do have actual diementions off nose gear?



Moodyman -> RE: Scratch building 105" W/S Super connie L-1049 G (12/27/2007 5:43:58 AM)

Here are a few pictures that show the tip tanks. my Dad took these in 1960 while in the Navy in Hawaii (Many hours in the Connies)
Didnt you have drawings that you posted in this forum with the nose gear dimensions on them? I'd have to go back and look but I thought that I had copied them from here.
KM



F-A-P -> RE: Scratch building 105" W/S Super connie L-1049 G (12/27/2007 11:22:18 AM)

Hi Sammy,
look at your post #:194, it´s a wonderfull drawing of the nosegear! Now I add some more drawings, thanks to Richie from Switzerland, I think you know him, where I got that documents.
If you want pictures of the nosegear send me your e-mail-adress, I have collected some.

Frank



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (12/31/2007 4:44:34 AM)

Hi,

Yes i know those drawings, if you look closely it doesn't have exact diementions that shows point to point lengths ie: from mounting point of the strut to support arms mounting points on the strut, distance from support arms to begining of sissors assembly!. I need those actual manufacturer drawings to custom build this strut as whole assembly.

As for tip fuel tank pictures, i have lots of them also and that is how i built the ones on the model currently.

Frank from your tip tank diementions i scaled them down to 1/14th scale and they would be slighlty over half the length of present ones, on the otherhand i will be keeping present ones as i also want to add 10oz fuel tanks in those tip tanks for more range of the model. I have plans for it.....[;)], i also have many pictures of nose landing gear, i am using them as referance/documtation purpose.

I haven't heard anything from Richie, can one of you guys ask him to send me an email with current update on his Connie project. Thanks



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (1/8/2008 5:13:38 AM)

Can anyone suggest me
Best possible way to
Route the servo wires in my
Model's Wing?. Is there a routing plan for 4 engined models.
Plus do these wires have to routed through
FG/cardboard tubes in
Foam wings?..



Boomerang1 -> RE: Scratch building 105" W/S Super connie L-1049 G (1/8/2008 7:41:32 AM)

It all depends if you want to remove the wires. From the look of your model it's too late to run any sort of tube unless you start hacking out the foam so you probably don't have a choice.

If it were me I'd just cut a slot in the underside of the wing & poke the leads in edge on. If the wing is sanded & ready to sheet put a little epoxy in the slot with the leads & the leads will actually re inforce the wing. Leave enough on the ends to solder the servo leads on & the plugs. - John.

Hi Sammy,

Nice to see that you're back at it. The Connie is coming along nicely.

I have been experimenting with metal myself. I have tried using aluminum foil but haven't found a good way to glue it yet. Others have suggested using chrome Monocoat.

I have used aluminum duct tape (Home Depot) and have had much success with it on my floats. It comes in widths up to 2 7/8", is brutally sticky, seems to be fuel proof and is definately waterproof. It looks awesome, and especially "glints" in the sky. I have recieved numerous compliments about it. It is also repairable if used in panels!

As you would expect, the underlying surface needs to be perfectly smooth or it'll show up with a vengeance.

Nothing sticks to it (including CA) and have found that when I need to add parts after-the-fact, I need to very carefully cut away the aluminum. I attempted to use a Sharpie marker to add panel lines and it usually comes off with time. If sufficient pressure is applied to the pen, it does leave a fine indentation that looks like butted aluminum.

It conforms to outside compound curves (you should see it on leading edges!) but doesn't shrink into concaves as well.

Because the tape is only 3" wide, I used it with longitudinal joints which I think was a mistake for 2 reasons. The longitudinal overlap doesn't look scale enough, and the long strips are hard to handle after the backing has been removed. Next time, I will use short pieces overlapped (1/8" is plenty) from front to back.

Cutting it is also a challenge. I liked using scissors but kept a container of solvent nearby because I needed to keep cleaning adhesive from the blades. You'll find an Exacto blade works OK while it's sharp, but dulls quickly.

If you have any other questions, feel free to contact me.

Hi Sammy,
I found some dimensions for the nose gear:
side strut: 35"
lower drag: 32"
upper drag: 40"
But I think the last value isn´t correct. I have a photogrammetry-software whereby I do some measurements and I think 42" is a better value for the upper drag.
For the nose landing gear strut I think you can use 77.6". All dimensions are refered to the axis.

Frank



Props4ever -> RE: Scratch building 105" W/S Super connie L-1049 G (1/17/2008 9:50:38 PM)

Frank

Thanks for the specs, I will forward them to machinest who is actually constructing the whole nose gear assembly for me.

Trevor

Thanks for sharing your experience on aluminum duct tape technique with me. I will be calling you one of these days. I Think it would be best not to apply tape longitudenally as you said. Working on panaling would be the better way.
