Tucker Gott is already legend in the comments!!! lol Great video. I've worked with fiberglass and carbon fiber. Most people don't realize how easy small fiber repairs are to do.
How ironic that you guys made a video on how to repair the scout after your #1 spokesman broke his in the icarus race (tucker gott) ;) good stuff guys!!
That's a very good repair. Thank you for sharing. For broken spars near their connection onto the frame, I find (based on the 8 I have broken) they break with clean shear fibers around the aluminum pipe/ring. I use painters tape about 1" out from the break to prevent unnecessary cleanup. Then I use acetone to clean the break area. Next, I use 3M DP 420 Black around the break, liberally, even getting it inside of the aluminum rod if needed. Then I wipe up the excess with a paper towel. Next I use a large roll of stretch wrap to wrap the part really tight, many times (5-10). Lastly if the break needs a bit more compression to hold while curing I will use heavy duty packing tape wrapping it very taught around the repair. This has a couple advantages, as well as disadvantages. It matches the fibers up nearly perfect-- looks new. There is very little need to clean it up afterwards. The downside is it will not be as strong as adding multiple layers of fiber around the outside. I really wish I could match the matte finish on the NXT Scout. I'm using west system 207 special clear and a wet layup for larger breaks that aren't clean breaks. It looks like the matte finish is from a prepreg mold and curing. Do you think wet sanding at 2000 grit but no further will yield a similar matte finish? Mine always comes out crystal clear and does not match. I matched the weight and fiber size and cut my fiber off of a much larger roll (50" width).
Suggestion: from a guy that uses rubber/nitrile gloves daily for work. use alcohol rub on your hands, wave your hands back and forth until completely dry, then the gloves should slide pretty easily.
People would still want to buy a new spar and when it arrives keep the repaired one as a back up. Which begs the question, how much is a spar? Maybe $200 bucks?
I was TOTALLY thinking about this after Tucker broke some spars. This looks like a simple repair in most cases. I am familiar with fiberglass work. The epoxy I use is vulnerable to UV light. So, I need to prime and paint over the epoxy. Is there any issues with UV exposure for this epoxy?
again thank you very much for your explaining and i want to ask you a question .....my prop is broke two pieces from the middle so can i repair with the same way (its model is fly products 130 mm)
+Mike Brady alcohol is good enough. For some reason we forgot this part when editing. But using sand paper does a good job as well as it removes the top layer with any grease included
In English the gum is called Modeling Clay or Plasticine. There appears to be 4 languages in Austria; I don't know any of them. Perhaps you might include a dust mask for kits going to the United States, as we have viscous lawyers here. BTW, as an ex-composites worker, please recommend wearing safety googles when working with resin. Resin is very difficult to remove from an eye. It took many months, but one day, I splashed my googles, right in front of my eye. All your stuff looks really cool, and well designed. No wonder why you have a popular product.
Can I ask whether you fine-sanded the fixed part and managed to match the pattern of the carbon on the rest of the part? Asking this since I am fixing some carbon parts on motorcycle exhaust and thinking about applying new layer of carbon since sanding damages the pattern of the original carbon/epoxy layers. thanx in advance a lot:
SCOUT paramotor thanks for your reply! I’m a huge fan of you and Tucker. I’m starting my flight training in the spring and I hope to be the proud owner of a scout. Keep on being amazing guys!
blackers10 yes but putty is still easy to say no matter what language you speak and is what kids play with as he put it. Not a technical name but does the job!
Should recommend the end users to wear a proper mask. Carbon fiber dust isn't your friend. Also, you could offer an STL file of the inside plug assembly. If someone had access to a 3D printer, instead of using the modeling clay (Plasticine). Or even better, offer one in the kit printed with HIP or PVA (polyvinyl Alcohol). Insert the part, epoxy the carbon and then simply use a water bowl to dissolve the plug. Cheers

Thanks Miro. That is great info to know we can make repairs if needed. 👍

10:40 Push the resin inside. 10:47 some magic trims and smooths the work. And voila! It's fixed.
Great job 👍👍🤙
Top job👌👏🏆
If only all paramotor manufacturers where this customer friendly.

Great that you are doing this video - the spars do crack and they aren't that hard (mostly) to repair. I've been epoxying mine but this is better.
Fantastic! Now I have less fear about purchasing the Carbon cage.
This was also my thought ... especially as a beginner I instantly ignored carbon because of the high risk of damaging it.

+Stanley Graves Tucker's unit is a new model that is even easier to repair than the old one on the video.
Thanks

No
@SCOUTaviation thank you for your Answer
What do you use to clean the surfaces of the broken parts to remove oils and dirt? Denatured Alcohol, Lacquer Thinner, Acetone, or what?
+Mike Brady alcohol is good enough. For some reason we forgot this part when editing. But using sand paper does a good job as well as it removes the top layer with any grease included
What size carbon sleeve is used in this kit?

I think I better stay with the enduro for my first paramotor. I think it will hold up a little better to my newness.

Making it look like new was not our goal. Yes, sanding would help.
We call it Playdough, at least in the U.S.
+Chasing Cornfields play dough is slightly different as it hardens when dried
+SCOUT paramotor plasteline is greasy and repels epoxy
ahhh, makes sense.
Chasing Cornfields how about Silly Putty? ;)
how did you cut the rubber band under layer 2 of the fiber?
+Mark Bourdo there is only one rubber band. I moved out onto top when I placed the second carbon sleeve
Miroslav Švec, what is the name and dimensions of the tool you used the clean the inside after the repair? It was some kind of rotary file.
It's called reamer, diameter 20mm H8
still waiting for my diesel paramotor!
Dude! YES!!!
How much is just one spar??
Can you repair a prop with this method?
+Dennis Thomas different procedure for prop... In some next video.
Is super glue strong enough for this for anything other than a temporary fix? Seems like it wouldn't last very long.
+Chris Grooms I used super glue only for temporary fix to keep it in place while laying carbon
Are those Tuckers parts?
+Tyler Longshore no. These are from our pilot friend from Austria. Tucker has a newer model
SCOUT paramotor thanks for your reply! I’m a huge fan of you and Tucker. I’m starting my flight training in the spring and I hope to be the proud owner of a scout. Keep on being amazing guys!
how a propeller to balance?
+Piotrek yes, why not. Next time
I think the "plastic gum" is "modeling clay." Plastalina is a brand name for modeling clay that does not harden in air.
+Stanley Graves yes. This does not harden an can be reused.
Plasticine
Plasticine, a brand of modelling clay, is a putty-like modelling material made from calcium salts, petroleum jelly and aliphatic acids.
Or a simple name like putty.
putty usually dries/sets
blackers10 yes but putty is still easy to say no matter what language you speak and is what kids play with as he put it. Not a technical name but does the job!
Don't you need to be a Amt power plant ratting to be able to relate propellers
