Now wait,, I think Velcro is awesome,,
for holding my grandsons shoes on
not so much for battery retention,, I can show you the scars on my airplane to prove it ,, and I was pretty thorough with my velcro,, my battery will NOT escape again,, I have two feet of logging chain holding it in now,,
well ok so its a bracket and a 4-40 machine screw,,,, but it aint coming out again,,
I know some people use velcro,, I will not do it again,, it cost me making the qualifications at the Nats,, 2100 miles each way,, hours of practice on site,, all for naught because of a stupid strip of velcro,,
I was very fortunate not to have my 13 ounce battery hit a person when it launched at 55 mph,, and bounce through the pits,, which incidently had the concourse winning airplane sitting there,, that would have totally ruined my "Nats experience"
