Cheapest Homemade Foamy

[js530]

Now that my CNC machine is *practically* running in all three axii, I thought a nice first project would be a cheap foamy, no more than three feet wingspan. Ideally, I'd like to get the whole thing to work for under $50, as my flying abilities are non existant One thing I do not know is control surfaces. Servos? Would this work? What is the cheapest transmitter/receiver? Thanks.

Hey js530,

Sounds like a great project. You can download some plans here for foamy planes:

http://3dfoamy.com/ Just go to the plans section.

As for servos, Hitec HS-50 or the 55 are going to be plenty. Put in a 3 cell lipo battery and brushless motor (like the hacker or himax or some outrunner around the 300-400 category) and you will be having a blast! I don't think however you can do it in $50 bucks. As for reciever the Breg is great (now by castle creations) or try the somba or maybe a hitec or something. That would be a cheaper route. The RX you linked to should work but make sure you get the right shift... positive or negative for the transmitter.

keep us posted

How 'bout an air aluminum battery? :P Highest density of todays batteries, only disadvantage is the inability to recharge it, the electrode must be replaced.

Would this work? http://cgi.ebay.com/3CH-RC-Radio-Sys...QQcmdZViewItem

Is blue home insulation foam (the kind that comes in sheets) suitable for this?
