Snowball - PROJECT

by FliteTest | February 17, 2014 | (27) Posted in Projects

The Snowball was the brain child of fourm member Lee. He smashed together two ideas from fellow scratch builders goldguy and Larry3215 to create the "ATV" of foam board planes. 

What separates the Snowball from a Nutball are the raised motor and the pontoons on the belly. 

Snow does not mix well with foam board, as everyone knows, so we built these big guys out of 1/2 inch insulation foam. 

It worked well with repelling water, but the material was too brittle in the cold. To see their untimely death check out the episode. 

So now we were back to square one, or circle one in this case. How can you make a Snowball that loves snow? 

Minwax is always a good choice but it's messy and we wanted to find some better solutions. So here are 3 of our favorites. 

1. Camp Dry

This is simply a silicone spray ment to help repel water off of boots and camping tents. The easiest way to apply it to your plane is to assemble it first (glue and stickers will not stick if you spray before you build!), tape off any electronics, and give it a good coat. Keep in mind this stuff is NOT water PROOF, it is water RESISTANT. Even that being said, this technique works very well. 

2. Colored Packing Tape

You can pick this stuff up all over the place. We got ours from

This method was the cheapest but most time consuming. The cool part is getting to design your own color scheme! Here, Alex went with "Don't Eat the Yellow Snow(ball)". Just make sure that if you are gluing two surfaces together, cut the tape away because the glue won't adhere too well to the shiny surface.

3. Laminate Contact Paper

This is another one that you can get at almost any craft store. This was more expensive than the tape method but looks much cleaner. 

The rolls come in a variety of sizes. Same thing as the tape method if you are gluing two surfaces together. Remove the laminate from whatever surfaces you want to glue together. 

This is the finished contact paper version. Shout out to Nolan, Blake, Randy, and Jedd from for sending us some stickers! Check out their reviews and send 'em some love!

Once we had our planes armored up, we took them for a spin!

We were happy with all these techniques to help our planes combat the harsh season. Use which ever method is more convenient for your project. 

If you want to turn your Nutball into a Snowball (or maybe add some floats to your FT-Flyer) we will have a conversion kit and plans available at the bottom of our build article!

Thanks again to Lee, goldguy, and Larry3215 for the inspiration! And thanks to you for watching!

Cool! Can the floats be used for water as well as snow?

Did you have to go to a bigger motor because of the added weight?

Just use Model Plane Foam. No paper to strip, and already waterproof.

Nice! I actually bought a roll of the sticky-back film a few weeks ago to try laminating foam board. Good to see it works 😀

why does it need the thrust angle? and how many degrees up is that?

Hey, have you guys tried Minwax Spray to waterproof your planes? I've tried it on a few scraps of foamboard, and found it to work just as well as brushed on minwax, and it's faster and cleaner too. The only drawback is it takes a little practice to get the technique right.

My technique is to keep the nozzle over a foot away while spraying back and forth and slowly walking around the foamboard. The coating appears to be much thinner, in fact it doesn't even change color, but I've tested it by running water over it with no effect, so it seems to work well. Lastly I noticed the Clear Gloss Minwax Spray doesn't require you to shake it for 2 minutes before using it, unlike the Clear Satin kind.

Wonder if sticky back film is paintable?

I'm chomping at the bit here, waiting on the float plans. The plane is ready to go!
You guys are great. Keep up the fine work.

Thanks so much you guys on making/proposing a great idea, to make out of a situation (snow) not to limit us out there keep flying no mater what!!! Make memories as you have always say! And making people to remember that there are people on your forum/page proposing ideas, recognizing them is what flitetest is all about! Thanks so much on keeping people thinking which is the machine that keeps us moving and enjoying even more this great hobby! Can't express more with words what the great rc community appreciate what you have accomplish! Thanks so much and fly safe!
