For sure!

The plans can be found here for both the depron version and original balsa... http://keyboardmonkey.com/twinkle

The original was just the old CDROM conversion motors, mounting the bearing tubes to the stick is simple. These days I fly them with a single stator cool wind from [link=http://www.customcdr.com/cgi-bin/ccp51/cp-app.cgi?usr=51H5086815&rnd=5713849&rrc=N&affl=&cip =71.162.38.107&act=&aff=&pg=prod&ref=20mmsingle&ca t=singlemotors&catstr=HOME:singlemotors]CustomCDR[/link] (tube mount). You can also use LittleScreamers DeNovo or any equivalent motor... there's actually a lot of motors these days, but the ideal weight is around the 20-24g mark. Some of the motors swing big props, so I find you can feed them enough prop with the VarioProp three blade swinging 6.5" blades. The hotter motors are naturally fine as they're typically built around the 6.5" blades or less (like the LittleScreamers or ParkJet or HotWind from CustomCDR). Others have used AXI's and things up. Can use up to around the 32g mark, but you'll have issues balancing.

For batteries, I use the 650mah 15C Kokams... 2S and 3S. The 2S packs are great for general flying, and the 3S pack with the VarioProp makes Twinkle absolutely ballistic ...there's also a lot of batteries around this size these days too... 600-800mah, 15-20C are a very ideal setup. I have flown on 450mah packs, which makes a very light and floaty setup (although naturally down on power as a result too), but you need to make sure you're not over-amping them with the motor setup.

...lots of options these days for the electric power train in this beastie.
