How do you make a spad for a cox 049

In the previous topic i asked questions about the tee dee 049 and i would be pleased if someone could tell me if a cox tee dee crank shaft can tolerate a diesel head or break.

Anyway i would like to build a plane for it. I would like to build a spad. I was thinking a pylon racer but i can't seem to find the info i need so could someone pls give me dimensions it would be great but i would also like to see 1/2a planes you have built, pylon racers or not .

Thanks i advance

You'll probably want to head over to spadworld.net and check out the Lil Ones section. They've done pretty much everything you can do with 1/2a. Be prepared to trim, trim, trim the weight and trim some more. Some really interesting stuff though. :-)

The tee dee has been dieseled before.  I have seen a number of examples in photo.  I do not think there was a different crank.

I would guess you have looked here

I didn't see 1/2a listed.

Try outerzone

a search for pylon brings back many hits. Quite a few are 1/2a. Of course none are plastic, so the lines are all you are getting.

On the Balsa Beavers website

under information is the PT-19 in plastic

The biggest challenge is you are going to be limited by the material weight.  Larger fluted plastic builds work well because of large internal volume making the wing loading manageable.  With small builds there is little internal volume so the wing loading become much higher than reasonable.  Consider foam wings with a spar instead of fluted plastic wings.
