I here of some incidents were battery packs fell during flight in Portugal WC.

What kind of Velcro (or other methods) is recommended? Links for commercial products would be greatly appreciated.

Thanks

Any decent velcro is fine as long as its 'sticky' and does not lose its fluffy bits. Best I found is as follows:

i. velcro on bottom of battery;
ii. velcro on tray;
iii. velcro slot on tray to be narrower than battery packs width, holds tighter;

For an even more secured restrain, have a strip of velcro on the top of the battery. That makes the strap hold even better. Does not slip.

Batteries are best secured by using a combination of Velcro under the battery + a strap across the battery. The strap should wrap under the battery's mounting plate so as to make the battery as secure as possible.

Hello Friends,
Velcro is not the ideal. Little bits of lite-ply, carbon and nylon thumbscrews beat the living daylights out of a fastener designed for clothing.
Perhaps a few of the folks who have designed and built proper battery retention setups will show us their handiwork.

later,

One thing I use is the velcro receiver/watch straps. Only need one strap per 5S pack. http://www3.towerhobbies.com/cgi-bin...?&I=LXPYM8&P=7

I also put a piece of neoprene sponge with double sided tape under the pack. It's about 5mm thick and stops the pack from sliding and gives a soft surface for the pack to rest on.

I'm using this set-up in an Extreme Flight 88" Yak and have not had any issue with packs moving during flight.

Regards
Jason.

Pappas ... I have had no issue using velcro. If you have a fastener on the top and bottom of the battery, it will not move and will hold fast. That means it will not slide on the battery tray and the strap that is going over the top will not slide too, giving you more grip on the battery. Use 2 straps per flight pack and its really secured. Only failure i ever had was when pulling a negative snap and the whole battery tray pulled out. Always remember to reinforce the battery tray if you want to fly hard.

I've noticed the Velcro straps get weaker with use. I just replaced them at about 150 flights. You could definitely tell the difference between the new and old.

I get commercial grade velcro from Lowe's. There really quite a difference in holding power (I still use a strap though).

Yoav,

I almost hate to post this because I caught grief for my detailed Velcro sleuthing , but I had the same question a while back which resulted in the following thread: [link=http://www.rcuniverse.com/forum/fb.asp?m=5349544]www.rcuniverse.com/forum/fb.asp?m=5349544[/link]

Post #13 has the real details, but the entire thread is worth a read.
