Free Palm Size Heli Plans

Free MIA Palm Size Drawing Template. The template can be printed to any scale by sizing in your printer program or bringing it into a GIF viewer program and scaling to what ever size you want.

The plans are Copyrighted, which means it can not be duplicated, reproduced, modified, reposted or sold without my approval. You are free to make as many copies for yourself and friends only.

Note the original scale provides an 8.5" rotor, this was done to allow anyone to make this helicopter and work from this size down, if desired, remember that the smaller it gets the more challenging it will be to work with small parts like the rotor bearing and hook.

The plan is adaptable to other means of propulsion, using ultra micro electronics and power systems. Start with Rubber first then you can experiment further with IR or RC equipment.

The drawing is straight forward but I will detail its assembly with additional photos.


1) Paper: You can use regular 20# printing 8.5"x11" white sheets
but lighter will work better for models under 8" rotor diameter.
2) 1mm Carbon rod cut to lengths shown on drawing
3) small pieces of 0.020 plastic or fiberglass, or carbon for the
rotor bearing support plate, the triagular brace and the main blade tip weight (shaped like the end tips)
4) Brass tubing 1/16" OD x 1/32" ID
5) Brass 2mm bead
6) 1/32" OD piano wire for the hook
7) Small Diameter 1/8" OD light tubing (coffe stirrers) for skids
8) Rubber band material (these comes in all shapes and sizes, the best one I have used is called Micro High Torque (25) grey rubber or sometimes called contest rubber. It is 1mm wide. There are other alternatives also.

Adhesives and Tools:

Small bottle of CA glue and Accelerator Spray, 5 minute Epoxie
Exacto Hobby Knife
Small Neddle Nose Pliers
Button Thread
1" OD Pipe
Small plastic bags

If no one else is going to step up and say this, I will.

I can't believe it, free and all, just like you said. Few days late.

Cute little heli Mario.

Mario, thanks for the awsome plans i'll be making that heli in the morning.

I'll try putting micro motorbike RX in and what would you suggest for a main motor? just a 6mm pagermotor? I have a 145mah lipo is that too big?

I appreciate it, I will explain later on which motors you can use and how to make a simple control system for it if you want to experiment with IR or RC control.

Let me just finish uploading some more instructions for it for Rubber Power first, since it is the mosts simplest form.

Attached is a better Blade Pattern. It has "tip weight and root reinforcement" details.
