Hi everybody. I wanted to say hello and to ask a question. Im new to foamies but I think I'm doing well with my first attempt. I have started working on an F-4 much like the one posted on Parkjets.com. So far ir looks great. It spans 27.5" made from blue fan fold, not the protection board. It looks great. It should weighcomprable to the one on Parkjets. I was wondering what I should power it with. THe airfram is stout, I would like to max out the performance envelope but not bust my bank account. Any suggestions?

Welcome to the site! You thinking brushed or brushless power??

I want to go with brushless. More power, more effecient. I like the hi-max motors. They look nice, Im not sure if I want to use a geard motor or an out runner. I do want it to have some power.

Take a look at these threads. I believe you will find some good help in how to size your power system.


50 watts per pound = casual flyer

75 watts per pound = sport/mile aerobatics

100 watts per pound = agressive aerobatics

150+ all out, 3D, fly to the moon!
