A lot of good info here.
When I bought them before way back when at radio shack I think I got a bog of 10 for 2.99.
I don't launch all that much due to funds, so not worried about corrosion all that much.
On the old pad set up, I sprayed silicone or WD-40 on the clips before and after, and never had much problems.
Kept the pad indoors so it wasn't subject to weather or drastic temp ranges.
Winter launches I just used a single Estes pad, mostly to fly a new bird just built.
All things considered, the response has been way more than I expected.
Thank you kindly to all.
And it sounds like someone else has benefited also, so it's all good.
But by all means, keep it going.
Never know when that one in a million hint comes along that you can't resist pulling the trigger on!
Hope everyone had a great 4th.
