Beginners crash drones. Intermediate flyers crash drones. Even pros crash from time to time! The ol' “what goes up must come down” is in full effect on drones – and sometimes they come down harder than you planned! So eventually you'll snap a part – we've been there! And here's the best glue we've found to fix broken pieces…
What Happens When You Crash Your Drone
We've crashed our fair share of drones. It happens. Especially when you are just starting out. Or many times it might happen when you get a new drone and you're testing out its capabilities and limits. Each drone has a unique feel for the way it handles – and sometimes you learn that hard way!
We've snapped blade guards, landing gear, battery doors, support arms, antennas, you name it – we've broke it! And we've also tried all sorts of glues to put them back together. We've tried several different super glues. Even super glue designed specifically for plastic. We've used rubber cement, epoxy, gorilla glue, bubble gum… yeah, just about anything and everything that is sticky.
Some of them worked, most didn't. Even the ones that worked were brittle and the part would break again in the same spot.
Using Glue To Fix A Broken Drone
We finally found one that works great! It's called Bondic – Liquid Plastic Welder. Heard of it?
We wanted to try it for a while, but it is more expensive than most glues, plus we assumed a lot of the claims it made were just advertising hype.
Turns out this stuff works as advertised… if you use as directed. You see, this isn't super glue. It is plastic welder. And you can't use plastic welder quite like you use super glue.
Super glue is good on clean breaks where the pieces fit back together nice and tight. When that is the case, use a quality super glue made specifically for plastic – like this stuff on Amazon.
When It's Not A Clean Break…Do This
However, if the break isn't clean – if it is jagged or missing small bits of plastic – then that is where Bondic really shines! You can actually apply small layers on top of each other to build up and fill in the missing parts.
It is also best to use very thin layers. Since it cures in only 3-4 seconds of exposure to UV light, even using thin layers is still a quick process.
You can even use both super glue and Bondic in combination to play to the strength of each type of adhesive. Use the super glue in the non-exposed area and then apply Bondic in layers to fill in any gaps and around the seams to really weld it tight.
Our Conclusion – It Works!
It is pricey. But it works as advertised (how often does that happen?!). We're glad we got the Pro Kit that comes with extra refills – we have a knack for hard landings, so this stuff will keep our quadcopters flying!
