About this Plan

Little Twister. Simple rubber powered helicopter model.

Quote: "The prototype of the Little Twister originally had two rotor blades but, due to vibration problems, a third blade was added. It is an indoor or outdoor model but, for maximum performance, it is essential to keep the weight as low as possible.

Little Twister is an ideal introduction to helicopters and it will fly up around the clubroom rafters, blowing years of dirt down! This draught can also come in handy for retrieving 'hung up' indoor jobs, it being quite easy after a bit of practice to position the model above the beam and blow the stranded one down!

Start building by assembling the spine on the plan and then cement two of the 3/32 in sq upright pylons in place. Remove this assembly from the plan, turn it over and cement the other two 3/32 in sq pylons in position. The remainder of the construction is done 'in the hand.'

Cement the 1/4 in balsa block hub on top of the four 3/32 in sq pylons and add the centre and bottom half frames. Now cement the two side 3/32 sq in pylons in place, then bind and cement all six pylon members to the I in. balsa hub. The undercarriage wire is bound and cemented to the bottom of the fuselage, also the motor peg gussets and the two 3/32 in sq bracing struts under the fuselage.

Now add the skids, which are made by rounding off in. sq. hard balsa, bind and cement well. Lightly sand the whole structure and cover both sides of the fuselage with light-weight tissue, but do not cover the underside of the fuselage..."

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

Doh, the previous plan in this slot (North Pole) was a duplicate, see North Pole (oz6080). Have shuffled the files around now, and put a new plan here in this slot, the Little Twister.

Hi, I've built a Little Twister Free flight helicopter and videod the build if you would like to add a link to the YouTube video: I've added a link back to the OZ page for the model in the video description. Cheers.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
