Making and fitting a Rubber Motor

This is how I make a fit a rubber motor for my free flight models, in this example I make three loops of 1/16th braided together. If you gained some knowledge from this video then hit the like and subscribe button (it's Free!).

Great little video Cliff, it's something of a lost art so the video is extra useful.

[@CliffHarveyRCPlanes]

Thanks Mark, a combination of watching videos, chatting on forums and practice gets the job done 👍

[@johnmetcalfe2482]

Thank you very much for this post as rubber motor construction has very little coverage here on KZbin.

[@CliffHarveyRCPlanes]

Hi John, thanks for the comment, I figured it was worth me having a go at trying to explain it, cheers 👍

[@dennishall2383]

Thanks Cliff. This has answered many questions.

[@CliffHarveyRCPlanes]

You're doing the right thing in researching Dennis, cheers.

[@jimbo2629]

There is a simpler/more normal way is to have an aluminium tube as rear motor peg and slide the motor over it with a push stick . Or put a larger diameter aluminium tube on the end of the motor. Tubes allow you to use a stooge for winding. Interesting way of flaring. I always wondered how to do it.

[@CliffHarveyRCPlanes]

Hi Jimbo, yes I agree with the second option as that's what I do, thanks for commenting 🤔👍

@@CliffHarveyRCPlanes Yes, but you saved me the time searching. Your Ka4 takes up a fair bit of space in your workroom.

Hi Zeke, glad it helps 👍

[@shawncharton9416]

Good Lord that is fiddley.

[@CliffHarveyRCPlanes]

Hi Shawn, when you've done it a few times it really is quite quick to do also you can have just one loop if you want but it will sag and potentially upset the cg 🤔👍

[@mewsdo]

Silly question, maybe... but is there any need for undercarriage on a rubber powered plane? Launched at shoulder height and landing on long grass... great video, by the way!

[@CliffHarveyRCPlanes]

Hi Doug, no need at all except if it's a scale model then yes of course, cheers

[@davidquerry8869]

Good luck tonight, Cliff.

[@CliffHarveyRCPlanes]

Thanks David, the video was actually filmed the morning of the first flight which is linked at the end, I was just keen to get the flight video out before this one 🙂

[@sarahblackett779]

Hi! Great video - where did you get the rubber? Been looking everywhere for it and no dice.

[@CliffHarveyRCPlanes]

Hi Sarah, what country are you in?

[@RasanthaM]

What is this rubber band type? Any online store to buy Please advise me

[@CliffHarveyRCPlanes]

Google 'tan super sport rubber', with luck there's a stockist in your country 👍

@@CliffHarveyRCPlanes I'm from Sri Lanka, not available in here I'll check their website 😃

[@dennishall2383]

What would be the best rubber for sail plan ? I was considering scratch building an ultra light plan and be able to launch with rubber power.

[@CliffHarveyRCPlanes]

I'm no expert Dennis, so I did what you're doing and that is research, basically the lighter the model the lighter the size of rubber it'll need but then you can have more loops to add power (but also weight!) and the propeller can make a big difference of course, cheers

[@perryamicangelo4008]

Ahhh, so that's what you do.....!

terima kasih

[@DoyleBlevins]

Nice tutorial, and that was not a S hook but a cup hook on the out side of your prop. A lot of the Pros use a reverse S hook for there rubber hook side. Now that takes some time to perfect but is very effective for holding the rubber on.

[@CliffHarveyRCPlanes]

Hi Doyle, thanks for the correction, ps busy building my FW190 👍

[@DoyleBlevins]

@@CliffHarveyRCPlanes Awesome maybe you will have time to get in your 20 second flight.

[@LeeRaven-rb4dp]

Sorry for bothering but I just have one question,having only regular rubber bands,would u think it works?Also how do I figure out which length of the rubber band would be correct for my model.Thanks! Lee.

[@CliffHarveyRCPlanes]

Hi Lee, no bother mate, if you're braiding the motor about 1.5 times the length of the distance from the rear peg to the hook is about right for any sort of duration. If you don't have access to buying your rubber by the metre then find the longest band you can, the longer the band though usually the thicker it is! The rubber motor in a kit is usually only good for a few seconds of flight. Here's some good info to read: freeflight.org/Library/TechLibrary/RubberMotorSizing.pdf 👍

[@LeeRaven-rb4dp]

Have you tried finding a flying club, I see there are a lot of rc clubs so there may be freeflight clubs as well, also have you checked Facebook for rubber powered flight enthusiasts in Sri Lanka?

[@pachanauta7083]

hi, how do you choose which rubber band measure is correct? and how long must be?

[@CliffHarveyRCPlanes]

Hi Julio, heavy models need a more powerful rubber motor, so say you start with 3mm rubber in one loop and it's underpowered you could try two loops braided together. If that's not enough you could move up to 4mm or 5mm one loop or two. See it all depends on the power required for a particular model. As for length usually about 1.5 times the distance from prop to peg, by braiding it will be about the distance from prop to peg, you need to experiment. Buy yourself a few metres of different sizes. Hope this helps 👍
