here is a couple of pics of my new project a 88 inch wing span fan fold p-51d

got some more work done yesterday started on the verticalstab

NICE !!! Coming along !!

YES YES YES!!
Love the BIG FFF planes - keep up the good work and more pics please!!
what power train you using? And batteries?

COOl!

Sweet!
Looking really good, Keep the pictures coming

WOW, that's awesome! Good work so far...

thanks guys ! ill figure out the power system a little later after i get a better idea of the final weight im at four pounds right now and hope to keep to eight. but im thinking a power 90 elect outrunner and lipos

That seems really heavy, but I've never made a foam plane that big

notreally when you consider most gas planes this size are 17lbs and up it has a lot of wing and should be a real floater

Did you build this one from plans? If so, where did you get the plans? I would like to try building something like that.

this model is loosley based on cf824 p-51 plans from flying models magizine
the construction methods i used make it a diffrent model
i use a built up wing and stabs instead of foam cores all formers are moded to allow for the 6mm fanfold skins and i will also be installing retracts. but i do plan on ordreing the cowl and canopy from fiberglass specialties, plus my formers are 6mm fanfold laminated with 1/16th light ply. i will also be adding wing fillets and other scale features as i go

Ah, ok, that is very cool. It's just a LOT of foam. The dollar tree foam I have access to is 2 ounces per 20"x30" sheet, so I would be at around 32 sheets of foam by now!!! I imagine glue can weigh a lot in a build like this too...

I doubt the dry weight of that air frame is much heavier than 4 pounds

what you do is build the stang to accommodate the size of the dollar tree foam and also buy a piece of 9mm depron for the tail feathers and load bearing bulk head and wing rib formers all the other wing ribs can be cut from the DT foam. You could easily build a 60" WS stang with 8 pieces of DT foam board and have some good size scraps left over.

that translates roughly to about 12 bucks for a 60" wing span war bird minus power plant and electronics.

Oh yeah, I am sure the electronics will make up 50% of the weight easily if a high power setup is the plan.

I'm experimenting in this type of construction with a meter sized Edge 540, based on 3DFoamy's flat Edge design.

thats cool
