Default $100.00 Scratch Build Contest: 60" Glider

I have entered this plane not because it will be a winner, but because it is very easy to build and very easy to fly. Less than $100.00 yes way less.

If the idea is to get more people to scratch build; this is a dirt cheap plane to build. I built one like it 2 years ago but only 40” wing span and my 5 year old grandson can fly it. It was the easiest airplane I have ever flow in forty Two years of flying. The plane along without gear will cost much less than $5.00. The plane that inspired this build was 40” but this one is 60” wingspan.

I started on it last night and finished it today. About 5 to 7 hours all total including installing the gear. It may be a few days before it stops raining here so I can do a test flight. I do have video of the plane that inspired this build which I will post a link to on youtube.

The first plane was ugly plain white and looks terrible but flies like a dream. Minus the gear this plane cost less than $2.00 to build.

I will do the post on this project in several pages to make it easier to keep up with. So here we go..

Here is the total cost of the 60" glider

1 piece of Dollartree foamboard $1.00
Pushrod Guides $0.02
Push rods 2 at .05 $0.10
Hot Glue 5 sticks at .05 $0.25
Hatch Magnet from HobbyCity $0.10
Washer for hatch Magnet $0.03
1300 KV Brushless motor from HobbyCity $7.99
8x6 Slowfly propeller from HiModels $0.19
4 rubber bands $.04
Dowel rods 3 at .33 Pat Catan’s $0.99
PVC Tape 2” Red $0.10
Servos 2 for $3.40 Including shipping $3.40
CA Hinge material $0.15
Receiver and crystal w/ shipping Bid Products $5.20
Motor and ESC connectors $0.50
Solder $0.15
10 amp ESC from e-bay w/shipping $6.20
Battery from Hobbypartz $3.70
Strait pins 4 $0.03
Electrical Tape for design $0.25

Total cost of everything $29.80
Total cost of plane and décor no/gear $3.02


Keep in mind that in the event of a total crash most of the time all you will be out is the $3.02 plus the propeller. Most of the other things will work for your next project.

The build begins with drawing the parts on a piece of foamboard. The next step is to cut them out. Then I begin with the 2 sides of the fuselage being attached to the bottom of the fuselage. I hstart with one bulkhead to hold everything in place. Next I add the firewall and to tounge depressers in the battery compartment to reinforce everything up front. I have also installed the front bulkhead for the servo and receiver complatment.

The next steps include installing pushrod guides and the stabalizer. I use small coffee stirers to make my guides 500 for .99 or five for a penny I used 6 of them.

The guides are hot glued to the supports to make things ridged. ant up to 1/16" wire slides through them effortlessly. I use an 18 guage floral wire at a cost of about .05 per wire. 2 wires used.

The next steps are explained in the captions under the photos. I forgot to mention I use a 3/16" balsa strip glued to the stabilizer this works as a reinforcment plus allows me to use CA hinges.

I think the captions under the photos tell the story.

Everything is setup in the plane now. The receiver was from Bidproducts. I bought 5 at $26.00 or $5.20 including postage. The 10 amp ESC was bought on Ebay for $6.20 including postage. Brass connectors were $.50 for hookup from Ebay. Battery was from Hobbypartz 800Mah 2s price was about $3.99. I have to look that one up. The battery is 800 mah 20c and cost was $3.70 I bought 5 or 6 of them, that price included shipping. I haven't found anyone that sell and ships batteries as cheap as Hobbypartz.

So I will do up a list with the final cost.

This is very cool, it seems Americans can get the electronics alot cheaper than over here in the UK. I think the minimum we can spend on a brushless motor is around £10 excluding shipping and servos are around 4-5 quid excluding shipping, never the less, a very cool little step by step guide that I may have to have a go at some point theres a spare TX laying around somewhere :P

Thanks Chellie, I've seen this tape before. I think I will order the 8 roll deal they have, one of each color. I like using this tape for adding color. I also have about 20 different rolls of colors of vinyl sign tape. I use it for my fuel planes.

This evening just before dark I had my first chance to make a maiden flight. And if flew very nice. We have been having rain here for the last four or five days and wind in excess of 25mph much of the time. It was acually raining when I made the maiden flight. So I will be posting a video but the weather is calling for rain for the next few days.

Talking $100.00 Scratch Build Contest 60" Glider with Video Flight

Today was the first day in over a week that the wind has not been over 30 mph or raining or both. The weather is fo forcast to be good flying weather for some time now. So when the wind was only about 15mph gusting to more than 20mph I made this video. It was too windy to fly but I needed to prove that it will fly. It would fly real nice in wind of less than 10 mph, but we very seldom have that at our field this time of year.

You can hear the wind whistle in the mic.

Im gonna put off setting up the voting poll until this weekend. Everyone get your price lists current if you want to be in the voting. I only saw 4 entries that had their price/material/source list posted. I didnt specify it in the rules, but Id prefer your price list to be on the first post. If you dont know how to edit your posts, PM me and Ill try to walk you thru it.

Here are some pictures of scratch built planes I have built in the last 40 days. There is also a 52" ugly stick and a 40" low wing that are not shown.

All but the Taurus was less than $40.00 the Taurus was about $45.00. Some people brag about how much they spend for their planes. I like to see how little I can build for. My average plane is about 30" to 36" and cost less than $5.00 to build without the gear.

So when you say scratch built for less than $100.00, to me that is a given.
