Dave,
Thanks for making this dimer plan available.  There are quite a few color schemes available; it's a nice looking bipe for sure!

What size motor have you settled on with the cut down prop?



Currently I have 4 strands of 3/32, 32" long.  I'm thinking that I could back off on that, though. She seems to have trouble handling high torque loads---much happier in a lower power cruise.  I may strip some rubber at 5/64" and try that, at a similar overall rubber weight.  Should give me a longer motor run and not so much torque monster...

Well my helper finally stepped out of the shadows and so if there are any "Goof's" I'm blaming them all on him! Shocked Grin Wink
Completed the canopy and cockpit area with the instrument panel provided on the plan.  I used strips of silver tissue applied with gluestick for the canopy framework.  I cleaned up the glue splotches with a bit of alcohol and a paper towel wrapped around the pointed end of a bamboo skewer.  Cleaned up nicely.  I also use the printed engine on the plan to finish up the noseblock.  Here's the finished SBC-4 (cheated on the finish using a "4" instead of a "3" type).

Looks super!  Let us know what your fight experience is....

Skyraider...finally dug through the stuff and found my scale.  Without rubber motor, but with prop/noseblock and finish she weighs 22.9 grams.  I think that's a bit heavy for this small of a model. But we'll see.  I don't use contest balsa.  I use the balsa I can find at Michaels and the local (50 miles away) hobby shop.  So I'm look forward to some dry days to give this one and a few others a toss.

The plan is in the Builder's Plan Gallery here.  Try searching for Curtiss SBC3.  Scroll through the results until you get there.

No worries here - you are right on target.  My feelings are that a Dimer or Embryo should weigh between 20 and 25g (of course, less is better).  And as stated, with two wings for more area, you will be just fine.  This Mitchell Helldiver it a great flying plane.

I was getting ready to go for a fling in the tall grass when I noticed my stab went potato-chips on me. Back to the board. I know not to shrink my tail-feathers, but I did it anyway and now I got bit in the a$$! Live and learn over & over ad nauseum...  I regret to inform you that the semi-vulgar reply above was plagiarized from Joe Namath in C.C. & Company, but he really got vulgar. I edited mine.
