Bunch of 2212/1000kv and 2200mah 3S - What to build?

#1
Hi, long time lurker here, but I have the "building bug" and a bunch of electronics left over from an old quad. The reason I am reaching out is: I have been having a heck of time finding plans for that setup. If any one out there has any experience with this please let me know! Thanks to all!

You should be able to comfortably fly just about any plane that calls for a C pack motor, which is most of them. Your motors are between the smaller B and the larger C pack motors.

They won't be as fast, or have as much power, but should fly just fine. When I was just starting out I used recycled quad motors that had pretty much the same specs. Had very good luck with everything I put one in.

I think I stuck one of those motors in each of these; Baby Blender, FT-22, FT Duster, FT Otter, Versa Wing etc...

B17 / C-130? ;)
The way I see it, you could build 4 small planes, 2 medium planes, or one HEEEEUUUUGE plane.

EDIT:
Don't be intimidated by making your own plans. My 1/31.5 XB-70 was based off of a threeview.
Making your own plans is easy, if you're willing to spend some time with a CAD software.

Start with a box-style fuselage and go from there. Add formers and some cardstock for rounded edges and a little more detail, if you would like. :)

Jason has a whole series dedicated to designing in sketchup here.

thanks!!

thanks guys for your quick responses
localfiend - sweet, i just finished a ft-22, looking at the blender, so my wife will be happy that i dont have to buy anything for it:p
pieliker96 - i actually was a little intimidated by making my own plans, but starting with a box and adding formers seems like a good route. as far as a huge plane, how do you set up 4 escs for differential thrust? i know how to do two, but four? sounds like a lot fun.

edit: what about the batteries(2200mah 3s 20C)? is there a minimum wingspan recomendation?

4 escs in differential is the same as two, just treat 2 motors (per each side) as two motors. Wire them as you normally would for differential, with splitters instead of direct ESC connections.

With 4 escs, you would be best off wiring all four batteries in paralell, which would give 4x the capacity and possible amp draw for the same voltage.

There isn't really a minimum wingspan for a set weight, as there are many factors that contribute to the total surface area of the wing (camber, chord length, height, ect.) but there are standards for wing loading. As a general rule, the lighter the plane per given surface area, the better (or vice-versa, more wing area for the same weight). Light planes tend to have gentler stall characteristics and can fly slower, a common trait of trainers. Aim for ~15-25 oz/sq. ft for general to aerobatic flying.

As far as actual wingspan, smaller wingspan gives less surface area to rotate through the air, and results in a snappier and higher roll rate, and example being The Guinea Pig vs. The Pun Jet.

Glad I could help ;) .
