The Hacker A20-20L is 1 of the hot new motors these days. I am just finishing up a 3D balsa park flyer with it on the nose. AUW is 13.8oz, woohoo. I am running a CC Phoenix 25 ESC rather than the Hacker X-20 ESC, though. I have 4 Hitec HS55 servos and while I have not flown them yet, I am not impressed. most likely I will go with JR digital micros again next time. The Hitec's are loud, rough and not very precise compared to the JR DS281 servos, but they are half the price also.

For foamies my vote goes to 3dfoamy.com or fancyfoam.com. They make some of the best foamies available.

For balsa 3D park flyers check out the Skeeter 30 or Skeeter 36 from billyhell.com.

The Hacker A20-20L is 2oz, but 2.4oz once the prop adapter and firewall mount are added(much to my dismay). The TP 1320mah 3S is 3.4oz. The CC25 ESC is .6oz. The Hitec HS55 servos are .28oz. I use JR Rx's and the 610UL is .6oz.
