iglowhead -> Brian Taylor Fiberglass P-51 Rebuild (5/6/2008 6:48:28 PM)

Having found out what I am working on I retitled the thread.
I will do my best to keep the project going and update here
as the work progresses. I went through my plans and found
a set of Brian Taylor plans that have been enlarged to a 72" ws.
Would that be a feasible size or would I be better off having them
reduced to 69". I am also considering going with a foam core wing.
Anyone know where I could get a set of 69" foam cores
for this model?
Thanks,
Tom



Hello,
I figured this would be the best place to go with this issue.
A friend of mine recently gave me this fiberglass P-51 fuse. It is a real nice piece and
have decided to make it my next project. I would like to know what I am working on
and could also use some advice on how to frame up the interior for the engine mount.
A photo of the firewall area on a completed model would be great. I'm guessing a .90 two
stroke would be a good engine choice. The length from end of rudder to back of spinner
is about 57". It takes a 4 3/8" spinner which my friend included with the fuse.
It is aluminum and not the best quality. Looks to be soft spun aluminum.
I did not get the wing but that is not a problem.
Thanks in advance for any help. I'll post more photos as the restoration progresses.

Here are some photos:

I put a Super Tigre .90 in the cowl and attached the spinner back plate.
Holding the backplate in place the glow plug lines right up with the existing
opening in the cowl. There is a hole on the top of the cowl that I am sure was
for a needle valve. Previous engine must have had rear rotor induction.

I am going to try establishing engine mounting beam location in the fuse
with the engine tacked in place like I have it. I'll cut a temporary firewall
and an aft bulkhead both with vertical slots for the engine beams. Once
everything is lined up I'll tack it with CA. That should give me good templates
for a couple of bulkheads with the engine beam cutouts located. From there the rest
might be easy. I'll post some photos later on. (if it works or not! LOL)

i'm thinking it's a brian taylor fuse. i haven't been able to find a length for the brian taylor fuse listed though.

Hi,
I also think it is a Brian Taylor fuse, based on the laminar flow airfoil shape of the wing seat. I don't know of any other ( non scratch ) fuse with this.

There are some build threads over on RC Scalebuilder for this model. You should be able to get plenty of help.

Cheers,
Merlin Man.

cowl gives it away , its a BT



tony-howard -> RE: i.d. this glass P-51 and help with framing front end (5/7/2008 2:34:02 AM)

I just measured my Brian Taylor glass fuselage - it measures 52-3/4" from the rudder post to the cowl face. These fuselages from Bob Holman came with a set of Taylor's plans for the wood version and they may have useful cross sections. There were no special plans that I know of that applied to the glass version.

The glass fuselages had a recessed section that ran underneath the cowl and included the firewall.

HTH



iglowhead -> RE: i.d. this glass P-51 and help with framing front end (5/7/2008 3:02:48 AM)

Thanks all of you for your responses. I mentioned Brian Taylor to my friend when he gave
me the fuse but was not sure because I did not recognize the cowl as a BT design. I had
a smaller BT P-51 and remember it having a more typical full cowl.
I just registered on RC Scalebuilder and quickly found a thread with some photos of a
built up fuse. It has the same cowl as mine and has proved to be helpful. Thanks for that
tip Merlin Man!
I have the 2 temporary bulkheads made. Will do the engine mounting beams next.
Hope to have a pretty good mock-up done tonight.
Thanks again fellas,
Tom

Hi

I have the glass fuse version of this model. It is a Taylor. The matt glass cowl, also a trademark of Taylor. And the wing saddle, laminar as full scale.

So, the matt glass cowl is original. I thought that maybe someone had repaired it
because it is very thick and weighs a ton. The wing saddle sure made it easy to
cut a pair of crutches for the bulkheads. I am making some progress and should
have some photos to post tonight.
Thanks,
Tom



iglowhead -> RE: i.d. this glass P-51 and help with framing front end (5/11/2008 7:18:47 AM)

Thanks to the info I was given here I found a site with some photos of a BT P-51 with the cowl off.
It was just what I needed to get me pointed in the right direction.
Have the engine mounted. Spinner aligned with the cowl nicely.
A couple more bulkheads inside the fuse
and some triangular stock will finish up the framing.
Time to build a wing!
Here are a few photos:

you might try wing mfg, i think its www.wingmfg.com



SCALECRAFT -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/12/2008 3:39:31 AM)

Hi

One of the challenges on the foam core will be the forward sweep. Dynaflite/Jemco had a nice little P-51D with a foam core. They had split the core at the root and a bit and inserted a wedge to push the wing LE forward.

Steve



iglowhead -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/14/2008 2:03:40 PM)

I checked Wing Mfg's web site but did not find any foam cores.
Will try calling them. Found a guy on eBay that will cut a set if I send him plans.
May try that.
I have been wondering about sheeting the leading edge at the root area.
Look forward to the challenge!

Here are some photos of recent progress I have made on the fuse:


I had to rotate the engine a bit for muffler clearance.
Cut cowl for muffler extensions.
I don't know about the rubber hose for the exhaust extensions.
It is automotive stuff. Thick and ugly but all I had. Will see how it holds up.

Rigged the throttle cable and cut hole in cowl for needle valve.



The Throttle was complicated by the muffler.
The carb had to be rotated a bit for clearance and
a bracket had to be made for cable. I used brass,
1/2" flat and 3/16" square tubing. Worked out great.
I hope the brass will hold up to vibration.

Measuring the needle valve location was easy thanks to cowl design.
[img]http://i19.ebayimg.com/04/i/000/f0/c6/7c72_10.JPG[/img]

I started with a 1/8" hole then installed cowl and checked location
just to be sure. Gradually enlarged hole installing cowl periodically
to check fit.

jaka -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/14/2008 3:46:30 PM)

Hi!
I don't want to make you sad in any way ...but that plywood you have used is is much too thick and heavy and will only make the plane too heavy!!!



iglowhead -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/14/2008 4:44:51 PM)

Actually it is not too heavy at all and I believe that it is the thickness called for.
It is 1/4" thick. With the holes drilled in it weight of the 2 pieces combined
is 12 ounces. I would have used aircraft grade but did not have any pieces large
enough and I like to use what I have on hand whenever possible.
Fuse with engine & muffler, spinner & prop, and fuel tank installed weighs 5 lbs. 14 oz.
and balances at the cg point very well.
Tom



jeff naul -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/14/2008 5:41:23 PM)

dynamic balsa has the brian taylor foam wing. http://dbalsa.com/
click on the left side of the page foam wings then on the right side of the page"replacement wings" then click "p" on the keyboard that comes up. scroll down to p-51 and i beleive it was the first on listed. jeff



iglowhead -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/14/2008 6:03:42 PM)

Thanks for the wing core info Jeff! I will contact them shortly.
I hope they have 69" sets. BT also made a smaller P-51 and the ad does
not give a wing span.
Tom



Merlin Man -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 12:26:29 AM)


Hi,

This request from a Brian Taylor fan who is very keen to see this build thread.

Iglowhead, is it possible and feasible for you to post your photos in the "normal" way ? For some reason unknown to me, I cannot open the photo files you have posted?! Or, if any one can help me resolve this problem? I am using Windows basic Vista.

Cheers and thanks,
Merlin Man.



iglowhead -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 3:30:05 AM)

I appreciate your interest in my project Merlin Man.
I'll do my best to stay at it and will try to post progress often.
I uploaded pictures that you should be able to see.
They are at the bottom of the post.
I ordered the foam cores from Dynamic Balsa. Hope they get here soon!
Tom



SCALECRAFT -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 3:48:41 AM)

Iglow

I believe Bob Holman is still selling the laser cut parts for these models along with plans. The wood wing "kit" has all the scale shapes and flaps cut to build quick accurate and easy.

This is just another option in case you are unable to find a wing. The draw back is the retract requirement.

Since the BT wing has a thin LG due to the scale laminar shape, the wing requires very low profile landing gear.

Unitract retracts, (England) are designed for this model. The retracts are not cheap, especially with the weak dollar of today. at the time i got mine they were around $250-$300.

I have heard people modify Rhomair retracts to work, but i have never seen them in action.

Looks good so far. If your model comes in at 11 to 12 lbs you should have a nice forgiving model.

Good luck

Steve



SCALECRAFT -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 3:50:58 AM)

I type so slow you posted your wing find while was typing.

Good luck

Steve



iglowhead -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 4:17:36 AM)

Thanks for the great info Steve.
Should I botch up the foam cores a built up wing will be the way I go.
And I just sold a brand new set of Rohm Air retracts! I knew I would regret that.
Tom



jeff naul -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 3:34:51 PM)

tom, have you ever looked into the fliteskin for sheeting foam wing's? one step and your done.http://www.fliteskin.com/



Merlin Man -> RE: Brian Taylor Fiberglass P-51 Rebuild (5/15/2008 11:35:01 PM)

Hi,

Thanks for the photos iglowhead, now I can follow your thread.

Cheers, MM
