Thanks. The conversion wasn't a problem. I made some really long sanding blocks from belt sander belts, rough cut out the foam pieces leaving spots at the corners to hot glue the parts to a big flat surface, then sanded them down until I removed all the waves which resulted in about a 3mm thickness. I cut the wings and fuse sides out of these sanded pieces. I only had to do a little adjustment so everything fit.

I was concerned that the bw motor would be a little small, but now that I have the Creators blessing, I'll go for it.

No landing gear. I fly from a field that has a gravel road for a landing strip or rough grass, so it would need really big wheels for rogs. Maybe even too big for a 'toon', if that can be

Big puffy wheels really add to the models character but at the same time it gives them attitude too.
come off the power and they act like speed breaks.

Progress is slow, but the wing is glued on, spinner mounted, pilot is almost ready, just need to fit the bottom panels and install the rx, esc and battery. Probably fly it before I paint it. Going with gear up because of field conditions. It's been a fun build.

Well I just tried to remove the gear on mine.
When I tugged on the wire to test the bond I found cracks in the foam.
(hard landings will do that )
I had to simply clip them off flush with the wing.
Headed to the field now to see how well it does with the gear gone.

Yester day was a learning experience.
The model loved not having the wheels, loops and rolls improved but the slow flight performance did not get much better.
She still tries to tip stall when it gets slow, it's just the nature of a wing with this shape.
Some wash out would improve this but I just plan to keep it at 1/4 throttle until it gets close to landing.

Interesting observations. How would you go about including washout in the wing design? I have been kicking around a few ideas, but thought it a good idea to ask.

That would be easy.
When the top sheeting is being bonded in place slide a shim under the aft outboard corner of the wing.
A tapered wedge piece along the midpoint of the aileron would work too.
I'd go with a wedge cut the length of the wing that starts at 6 or 7mm and tapers to nothing.

Anyone else want to post their build?
I'd really like to see the paint scheme you went with.

Hey,
Mine's ready for the maiden flight, then paint, but every time I have time to fly it's been windy.
The real Spitfire didn't have much for different paint schemes. I was probably going for the tan and green camo job....

All the dogs are on the site now and a few other cartoon pilots as well.
I don't think the boys will fit in this one though.

Said I'd be back with updates

So many of you have asked about adding a rudder.
The Cartoon ME 109 still has its wheels and tends to takeoff in a left hand turn.
little scary and some planning is involved so I decided to add a rudder.
lots of room behind the fire wall and all I had to do to install it is to poke a long wire through the bulkheads.
Taxi testes in the back yard have been very promising.
I'll be taking it to a paved runway this weekend and let you know how it did.
I'm very curious about how it handles having a rudder in flight.

A thought before I start my build - putting a 1 or 2 degrees of washout in your wing method would be reasonably easy - how about increasing the wing %depth at the tip; my experience has been fatter tips help ward off tip stall and this might be simpler to build in ? What do you think ?

Is this similar to the motor you used http://www.hobbyking.com/hobbyking/s...idProduct=5430

That is the motor I used.
Looking at the spit wing from the tip I have zero wash out built in.
When I build the next one I'll add some , it is sure to help the problems she has.
I wish I could tell you how to do it but it would be speculation.
what I do know is it has to be done with shims at the trailing edge while the top sheeting gets bonded in place.

Last elliptical wing I built in foam I put a 1.5 degree foam wedge under the wing tip chord, and then measured the trailing edge length back to the root and created a wedge that length and bent it under the elliptical trailing edge. Worked fine.
Ill do this on my cartoon spitfire build when I get my kit from you
