So I have to admit,I love the Spitfire....I also love the simplicity of foamboard construction,hat off to the guys at Flite Test.
Anyway,my version of the Spit is a little different.Its still the same size just weighs in at 950grams or 2.1lbs....without a battery :)....
oh and i added working flaps.
Ive built a few of these planes now and it struck me as silly having your battery hanging right in the most dangerous place(in case of a hard landing) and the esc inside the power pod,so why not swap them around.I also decided too fix the powerpod in place.The obvious benefits are your esc is hanging right in the flow of air from your prop and your battery is safe inside the powerpod behind the bulkhead.
This obviously brought about the issue of how too access your battery,so I used pink insulation foam to replace the turtle decks and cut an access hatch to gain access.
At this point I was on a roll and decided on adding flaps as I just wanted too see if I could make them work....Why not ?? :)
A little thought went into the desgn of the flaps,I wanted them hidden and only visible when in use,I extended the underside of the wing and cut them into the foamboard the same as you would say an aileron,mounted a servo per flap,ran the cables out beside the aileron ones.
I also tried too compensate for weight affecting the CoG,a previous model similar to this had balance issues.
Tail servos were mounted directly under the cockpit and snakes used for control.The bulkhead on the powerpod is 12mm plywood and the motor is a E-power 2810 1100kv 40a motor weighing 79grams....60 amp ESC and a Master Airscrew 9x5 3blade prop and spinner completed the powertrain
turns out it was still tail heavy....enter 1 spare alloy wheel nut curtesy of my old car and ...perfect :D CoG achieved.
Anyway...enjoy the pics.

It took a few attempts too get the CoG sorted but once I did it flew very well.The flaps didn't cause any adverse or unwanted control issues but did exactly what they were supposed too do,this was however the 1st attempt at the modifications I made so I feel more testing is needed and I really want too add retracts so I will carry on with moding the bird.

A link too one of the vids..I hope ;-)
bear in mind this plane weighs 2.1lbs without a battery,I think it's quite slow with the flaps deployed.

as for how i did it,its just a standard FT Spitfire but I used pink insulation foam to add details like radiator,airscoop and oil cooler,I also filed in the nose and sanded too shape.
The flaps were a little more complicated but I have just posted an article on another mod for the Spitfire showing the workings and how to install them

I think the beauty of this hobby is theres no right or wrong way to do anything,just use a little imagination ;-)

I love rc Warbirds looking as they should with 3 or 4 blade props.
I'm building the Spitfire and would like to use a 4 blade prop.
Is this possible on your setup?
I'm also having troubled finding a 4 blade prop and spinner.
Keep up the fantastic work.
