These smaller models without flaps really need to be light!  There is an ongoing discussion about weight in the larger, higher powered models.  Generally, I find that lighter is better, even in a 60-size plane.

A Flying Clown in electric would be tough to make light!  The weight penalty in batteries would defeat any attempt to come in under weight.

I have an electric Ringmaster, which is just so-so because it's too heavy.  On the other hand, I have a Ringmaster with OS 15 that is now at 17 oz.  It was a couple oz. lighter before it shed a wing and had to be beefed up!  Of course, special construction techniques are necessary to achieve that weight. (one dare not crash such marginal-strength construction).
