Parts added...still pending wing LE stiffener, wing struts, landing gear, wheels, nose block.

As of now 4.5g, if going with capacitor powered system would add another 7g, then some more for the pending parts about 2g, total ending at 13.5~14g range...sounds heavy!

If going rubber powered, would probly end at about 9~9.5g (with prop & motor)....hhhmmm, something to think about.

7mm motor, 16mm long. 77mm prop, 4.7F Super capacitor, about 7g total weight

Looks like about 15-20s of useable power, the rest of the time would probly be used to ‘fly’ the model down.

Im still on the fence about this setup on the Poullin.

that's about my setup....it's on a sopwith camel, not finished yet~but motor run seems power+time.
I like the idea of no timer or worries about draining the batt all the way......and seems the way to go on small planes.
I will be watching for flight reports!
