Default Can't Replace, so Repair!

Okay, last week I broke one of the thruster booms during a crash. Can't find a replacement part for it locally, and need to get it fixed for flying this Wednesday.
What's the best way to fix the carbon thrust boom?

You can do what I had to do. Lowes sells square alum tubing that is just a hair larger than the stock carbon rods. I replaced the coated wire out of the stock arms.

The tubing is in the hardware section, hobby parts bin. 2 pack of 6" square alum tubing. I used solid core wire from radio shack and reused the factory connectors on the 4-1 and motor sides.

I don't think I need to do any wiring work, nor do I want to. I just want to fix the thruster boom.
Wouldn't the aluminum tubing make it heavier also?

The alum tubing is grams heavier. Not really a noticable difference. And if you don't use factory booms, you are going to have to split the broken ones open to get the wires out. Personally, I don't like messing with enamel coated wires. I was surprised how easy it was to re-solder the factory plugs onto new wires.

Perhaps someone else has had success in this area. This was my first attempt, and so far so good.

Well, thanks for the tips. If worse comes to worse, I suppose I can fly my two Flyzone airplanes, the Albatross and my Red Barron Wednesday. Hopefully, it won't be too windy for the little guys.

a very useful trick i do all the time with just such repairs. using a very small amount of superglue, glue the boom back together. just enough to hold it in place. then, using some sewing thread, get a small amount covering the cracked/broken area with a little excess on either side of it. then start wrapping the thread around the glue while its wet so that it soaks into the thread. once you notice it is starting to look a bit dry, get the thread wet with more superglue and continue wrapping. do this as much as you feel is needed to make it strong. it works as a excellent cast and usually holds up indefinately. as an example, i have used this method to repair broken dog bones in rc cars and had them run just like new. the only downside is that the cast area will be slightly thicker. other than being a bit of an eye sore it shouldnt have any negative effects, and will get you back out flying until you can get a replacement. hope that helps you

I'll keep that trick in mind. Thanks.

Wouldn't the alum booms be more prone to damage even in light crashes? I've cartwheeled my MQX a few times with no damage, but I'm not sure such a thin piece of alum. would hold up to that.

I've wondered about adding extra thickness to the boom where the motor cover snaps into place. I don't want to add any thickness in the area where it might interfere. Will have a look at it later today. Thanks for the tips!
