I just received my package from Dog House Rocketry. I actually intended to just order some rail buttons, but found something new listed: Charge Wells.
The charge wells are well constructed our of high impact plastic. I would recommend them to others. I tested on in my back lawn and I am readily impressed with how durable they are. 3 tests and no damage. I can't wait to test them in a flight.
On the down side, they only come in 0.5 and 3 gram sizes. I will recommend more sizes today.
