What do you mean plans?
Like setups? Combos?
Or a plan for the craft itself?

Well making a slow stick is pretty simple, all you need is a long stick like one of those 1/4 by 1/4 square rods from home depot(so they can fit astick motor mount) a certain wingspan and chord(so you can decide if you want the craft to be a floater or if you want it to be pretty fast) and a simple rudder and elevator. Ive built several slow sticks before umm i was wondering what materials do you have? Your title says FF like Fan Fold? like blue or pink that stuff? I would say you could just bend a simple under cambered wing.

If you'd like i'll draw out a simple design.. i may even have some sketchup plans for ideas..

im happy to help you out i was just unclear what you were askin

Id say just start with something simple. Have 2 20in wingspan wings probably 8in chords with an undercambered airfoil. Put an angle in the joining halfs so you have a pretty deccent dihedral. Then find a stick about 25in long... or 20 whichever you'd like. Then make a simple rudder probably about 4-5in high and a tail that is about 10in long... make sure the control surfaces are atleast medium size a slow stick flies slow so you need pretty deccent control surfaces sicne there isnt much air moving through your plane.

you should get somethign like this:

Ahh well yes it can heres one of mine ive built:
http://video.aol.com/video-detail/sl...ing/1761416356

and another
http://video.aol.com/video-detail/pa...31?icid=acvsv4

by the way if you would like another cheap source of foam Dollar Tree Foam board works great.

Wait so do you have a Radio system and powerplant already available? or i mean waht do you ahve to build with? do you at least have a radio?

A simple powerplant would be a 7cell 8.4volt 600mah nimh pack and an EPS300C thats waht powered my slow stick in the video it had pretty nice power.

If you want to fly in some winds, you will most likely want to go with a flat bottom wing. Meaning you ahve a curve and you have a flat bottom part as illustrated below:


now you can make one two ways, you can bend a piece of foam then take another set and put it flat under.. or you can just carve a flat bottom airfoil. Only reason i say it should be a flat bottomed airfoil is that undercambered airfoils dont do too well in wind.

2 18in wingspan wing pieces would make a 36in total wingspan so as long as you have a chord that totals up a wingarea that can hold your plane at 10oz for a trainer then you are fine.

Here is a calculator below:

Here is the simplest thing to do:

Assuming you have motors, batterys, escs, servos and chagers plus a radio.

So you have a stick k, first thing you will want to do is decide how wide(chords) your wings will be, so we'll start with 8in by 18in(makes rectangel) so you have two of those and you have 8x36ins. So you just take your foam(assuming its thin) and bend it over a curved surface such as a PVC pipe.

If it is the thick foam then sand it down into an airfoil like the picture above(make sure it is thick so your plane can fly slow)

you said youve built planes before so how is this any difficult? i just dont really see what you need help with. The body itself only costs less than 10dollars do you need help with electronics?

Well then all you gotta do is build up a plane. What powerplant do you have? so i know like what approximate weight the craft will be ill draw out a plane for ya to build i would just say build whatever you want. But yeah give me an idea of what powerplant you'll use and ill design a simple slow flying slow stick.

Bending wing panels over a curved object like a PVC pipe works well. I've also used the edge of our kitchen counter and the edge of our bathtub!

If you want to get fancier, build yourself a Bendfoam Jig. It works well.

Hello JPS ,

I hope this will help you .. I Have used graves rc several times and just ordered another slow stick from them .. They are $18 bucks without the electronics ...

If you are using the 2410-08 then your on the same track as me ... I use the 2410-09 and sometimes get them from Heads up RC . Com ... Jeff the owner is sooooo helpful and has good low prices and the shipping is only 2 bucks for ANYTHING he sells any amount ... And the service is great ... Fast and friendly if you have any questions Jeff is there and answers them fast ...

So anyhow I am gonna try to post links 2 those 2 sites ... I also use Hobby City of "China?" sometimes ... the prices can be less but the shipping is more $$ and it takes ...... a while from China .. so you need to weigh the difference to decide .


OK this is too long .. I do that a lot ..sorry here goes the web sites ... I hope this helps .. Let me know .. Don J.

Hey , JPS ... I forgot .. check out www.headsuprc.com As Jeff has lots of good information on there .. If you click on the 2410-09 it will explain how they are so good for the slow stick ...

He also sells comos with the ESC also .. The only thing is the receiver and I have been getting them from http://www.b-p-p.com/home.php they have berg receivers at great prices and are also great people to deal with ...

THERE ! ! , You have all of my secrets .. I am getting better at finding ways to build planes but still need help flying as I usuall fail Miserebally (sp?) .. Hope this helps , Don J.

But he said scratchbuit

i dont know maybe him buying a slope kit of a slow stick would help him experiment around with it and then build his own slow stick from that. Yeah i think that would be the best way to go.

What kind of foam do you have? i know its blue but is it the thin stuff that is folded or is it the thick stuff?

Getting back to the original question, check out the BluStik.

The plans for the BluStik show how to mount the servos. Attach two pieces of bamboo shish-kabob skewer to the fuselage stick, then use rubber bands to hold the servos in place.

I've used hot glue myself. It works great for servos, and it can be removed if you want to re-use the servo elsewhere.

I've also used servo tape (double-sided foam tape) to mount servos on stick-type planes.
