OK got bored and took a look, Paul was right is impacting on the skin, given it a sand and its much better will do a bit more tomorrow to get a final fit.  Some skin has been sacrificed to get a good fit but should be able to repair it quite easily.  

Then the fun of sorting out the flap servos and then covering the wing will be done....... 

[Warbirds Replicas P51 Mustang]

 I did trim it just not enough I think. 

Will have a fettle at the weekend. 

 

thanks for all your help guys 

[Warbirds Replicas P51 Mustang]

Ron, 

I am not 100% sure.  I think it might be the prongs impacting on the skin. 

Now I have confirmed its wrong I can take a better look, the prongs are not hitting the walls. 

[Warbirds Replicas P51 Mustang]

Going to join the wings together.    

Does this gap look OK? 

Also what's the best glue to join them?  

Thx for your help

Jon

[Warbirds Replicas P51 Mustang]

Trevor,

Thanks for that prompt response. That is what I was thinking that Paul had meant but thanks for helping out.  

Good luck with the maiden.

All been pushing on with the build in the few spare hours I have.  

 

I have got the motor mount sorted thanks Richard for the cross mount.  Also cut and drilled the spinner.

 

Now the question  is how do I assemble it. 

I have re-read Paul's post on the subject but not sure I am any further forward.  This is what I have so far. 

 

Any help would be great. 

thx

Do you get kicked out of the Warbirds Replica club if you do a pink or civi warbird....  just asking for a friend ?

 

[Warbirds Replicas P51 Mustang]

Looking good

[Warbirds Replicas P51 Mustang]

Andy,Graham,

Thanks for your help, I do have the long one but I find it a bit awkward to use, but I will give it another try.  Good idea on marking the centre line I tried this on the elevators and it did help.

 

 

Any advise on the items below. 

1. What is the best location for the rudder and elevator servos is it Paul's revised location? 
2. What is the best way to cut the canopy so it fits nicely round the curved surface
3. Anybody know where I can get a cross mount for the fms motors,  I have asked Richard but failing that any good ideas

thank you all again.

Jon

Graham, 

I have the permanent grit sanding block.  Mostly use the less course side.  It's just getting for instance a consistent shape both sides of the leading edges of wing tail etc.  

Thanks 

Jon

[Warbirds Replicas P51 Mustang]

OK trying to crack on. With the build. Made a long list of jobs with page numbers of pics on the forums... aiming for Christmas... just got the elevator wire fitted and sanded to shape.  

Will post a pic tomorrow  for those up for a bit of a laugh.  

Anyway the job list has generated a list of things I am unsure about. And beg for your collective wisdom. 

 

1.  I am assuming I should pin the elevator and rudder like I did the flaps etc.
2. What is the best location for the rudder and elevator servos is it Paul's revised location? 
3. What is the best way to cut the canopy so it fits nicely round the curved surface
4. Anybody know where I can get a cross mount for the fms motors,  I have asked Richard but failing that any good ideas
5. Help with sanding, I am not very good nothing is even or the same shape any advise? 

 

OK now I will breath and wait the collective knowledge ???

I've been called a lot of things Jonathan but Ron is a new one. Still better to be looking at plans and not headings. 

Eric,

Sorry I was on a work call and trying to multitask between work and non-work.  Clearly failed at both. ?

Good to see you are looking at the plan now Jonathan.

 

Ron its pinned on my wall above my build.  I did build the wing over the plan as suggested by Richard. 

 

Thanks to Paul's clarification I will bend the wire not the wheel. but not bent tail wheels before so unsure of what shape should I make.  Looking at some of the pictures I could probably make a guess. but any help would be great. 

 

Thanks

Jon

 

[Warbirds Replicas P51 Mustang]

Paul, Ron,

Life savers as always.  

It looks so easy when I see all the work on here, still loving it but each step creates more questions.  

Like when bending the tail wheel is there a pattern looked on the plan cannot see one.  

I will definitely be doing a fixed tail wheel. 

 

Thx

Jon

[Warbirds Replicas P51 Mustang]

Thanks Paul,  every time I think I have my head around this build and have read and re-read your posts I find another thing I go what the heck does that mean. 

 

I have a few more general questions which have been perplexing me that people a bit more advanced can help with: 

 

1. Looking at the 4S 4000mah batteries what C number are the people who have them in the air already recommending.  My thoughts are between:  
   • Turnigy nano-tech 4000mAh 4S 45~90C Lipo Pack 
   • Turnigy Nano-Tech 4000mAh 4S 30C Lipo Pack 
2. Would it make sense to sort out the tail wheel before I sheet the top deck - is access an issue or can I wait to do that when I do the bottom?
3. Same for the snakes I am thinking it would be easier to do before sheeting
4. What method do people use to fit the wire for the elevator do I need to drill some holes and file a grove or will it push in ?
5. When do you attach the servo horns, do you wait till you have covered it or attach them then cover or attach, then remove for covering.

Thanks for all your help I am trying to plan my next steps

Paul,

Not sure where the 5mm goes to and from can you elaborate looked at the plans and cannot seem to see it.  

Thanks 

Jon

[Warbirds Replicas P51 Mustang]

Andy, 

Thanks for the help. They are not stuck on yet just held with tape to see how everything aligns.  

I think I will attach the cockpit former then the half  sheets and cut / sand to fit as you recommended. Thanks for the help

Jon

[Warbirds Replicas P51 Mustang]

Hi,

Another question about the best way to do things.  

I am wondering the best way to sheet the front of the cockpit and attach the dashboard rib.  

I have wet and shaped the two half's of sheet and I am going to join them using the method shared by Andy.  But still unsure how to get that Nice curve around the dash and do you attach the dash rib first. 

 

Thanks for all your help

Motors...

If you intend to use the FMS four bladed props don't go much above the FMS 580 KV motor as they have been known to fail if their driven to hard. (speed freaks always break something)

If you are going to use a two bladed prop then just match it to the motor. There is usually plenty of info online.

Add some small magnets to your shopping list for the hatch retaining too. Ebay is your best bet. I use 8mm disc ones.

Talking of which...

With the hatch cover in place mark the location you want to put them and drill through both the cover and the frame underneath, drop of medium super glue, don't forget to de-grease them before gluing. Or epoxy.

 

That style of drill leave a nice round hole..

/sites/3/images/member_albums/156134/875422.jpg

I had a small errand to run today so this has held up the build............

 

 

Paul what glue did you use on the magnets I am thinking super glue?

[Warbird Replicas Bf 109 club.]

I would love this or the spit as my second WR model

 

[Warbirds Replicas P51 Mustang]

Andy, thanks for that, yours is a simple but elegant solution.

I will give it a go this week when I get some more clamps delivered and get the side skins on. 

 

Jon

[Warbirds Replicas P51 Mustang]

I have been working my way through the fuselage and I have a general question. 

When I am skinning the curved deck how do people ensure the two sheets fit I.e. same length and will join nicely.  Mine don't but together we'll and one is usually the wrong size needs a  mm or 2 off then is wonky.  Any basic wood work advise welcome.  

[Warbirds Replicas P51 Mustang]

But I lined them up and they match almost to the mm so, thanks to Richard even an Idiot like me cannot mess it up. ?

 

[Warbirds Replicas P51 Mustang]

Hi, typical I just read your post Gordon after I glued the profiles together last night.  I am waiting on a clamp delivery (always need more clamps) before I start gluing it all together. 

 

[Warbirds Replicas P51 Mustang]

Eric, again thanks.  I keep forgetting to use that as a reference. 

 

Couple of quick ones. 

With the side skins what is the advantage of joining them all together as Paul did or doing it as Richard did in the instructions and leave the tail bit  until later.  

 

Also from what I can see some B's have a rounded back some a square.  What's the thoughts of the B builders on what shape and how to achieve it. 

 

Thanks 

Jon
