ESC coming off after flight

Use 3M's extreme velcro. Or just superglue the velcro to the ESC and the Plane. I'm assuming it's the glue which is warming up and coming off, not the velcro hooks.

I misunderstood, Wan. I thought you were trying to glue the Velcro to the model's interior, so that it would hold the ESC securely once wrapped in the Velcro.

I suggested silicone glue because it is fairly inert and doesn't attack many materials, while being relatively heat resistant.

I think Norm has the best idea.

Ed,

Silicone would be ideal if it is removable from the ESC. Perhaps I could do some experimentation with silicon on similar plastic of the ESP casing and see.

I can't find 3M extreme velcro anywhere. It would make things a lot simpler if someone could tell me where to get that velcro. I'd like to give Norm's suggestion a try though.

Thanks, Wan

Wan, sorry I don't know why I thought it was made by 3M. It is made by Velcro brand and is called Velcro Extreme, part number 90800, All Weather Rough Surfaces. I found it at my local Home Depot, it's in a box with 5 strips. I did a search on

and with no luck, you may want to give your local hardware store a call and see if they have it or can special order it. It's temperature rating is up to 175F. Ed's idea of using Silicone glue is just as good, but to make sure it doesn't permanantly adhere to your speed control, wrap some scotch tape around the speed control, this way the glue adheres to the tape not the ESC, and if you ever want to remove it you can just peel off the tape. I do this all the time with servos I have to glue into a foam wing.

Jim, Thanks for the idea, but it sets me to wondering about if my ESC should be getting hot at all. It had no problems for about 50 or so flights.

The ESC I used is the type JETI ADVANCE 40-3P for brushless motors. It served a 12 celled NiMH 3000 mA battery pack at 12 volts. Hope I'm making myself clear.

Wouldn't wrapping the ESC contain the heat or is my ESC faulty? Any input would be greatly appreciated.

Wan

Probably, but a little heat retained by a full wrap is better than the problems your ESC might have with the acetic acid vented by (most) curing silocon componds. You can always vent a little more air around it and the Velcro does allow some air travel through the hook and loops.

Now as for the actual condition of your ESC, I don't have a clue. Sorry.

Jim,

I went out to fly my plane and the "High temperature" velcro from Radioshack, came off so I now have your idea of wrapping around the ESP implemented. But I did cut the velcro in the shape of an H, with the cross member of the H wider in order to adhere to the other part of velcro. I hope this would help to dissipate some heat.

This time I used "Industrial strength" velcro I found at the local hardware store. I am pretty sure this combination of ideas would work. Will let you know after the next flying session.

Thanks to everyone, Wan AMA 773188

Thanks Natural, I'm sure CA would've worked, but I don't want the ESC permanently stuck to anything. Hai's use of double faced foam tape, Norm's wrapping of tape around the ESC, then silicone glue and other suggestions would all work and are appreciated.

I used Jim Strobel's idea of wrapping the velcro around the ESC because of that's what I have at hand. I took my plane out after work and flew it 4 times and the ESC stayed on.

Thanks for the help. Wan

Oh. Did you understand what I said, that I CA'ed the VELCRO to the ESC?

Whether that constitures "the ESC permanently stuck to anything" is a moot point :-)

Frankly, in smaller planes. I let em flap inside the model :-)

I had a chuckle when you said "I let em flap inside the model" : ). Frankly the ESC was flappin' outside.

I wasn't going to respond but couldn't help it. I took some bugs for some wild rides on the last flight. How about that?
