Hello fellow rocketeers, I hope you are doing well. I am currently designing a rocket that will fly with a G or H motor but I have a problem. Because I live in Spain and here, rocketry isn't commonly known like in USA and around, it is very hard to find and buy certain elements. Today I'm struggling with the motor ignition. Because e-matches can't be shipped from different countries due to hazards, I'm planning on making my own following the steps that Richard Nakka states on his website, but that's another thing. What I really need help with is to get myself a decent launch controller to be able to ignite and launch HPR motors.
I have found just a few rocketry websites around Europe but the few ones that have launch controllers, they are:
1- not suited for launching HPR motors
and or
2- too expensive
So, bearing in mind that launching rockets isn't going to be a day to day thing for me (at least for now), I thought of building my own, following serious tutorials of people that know what they are doing (I really don't have that much knowledge about electronics, sorry). Some minutes ago I found this custom made launch controller that seemed pretty simple and efficient enough for it's purpose but I have some doubts and I want to hear the opinion of the really experienced and talented people around here.
The first is: is this launch controller build reliable? Would you recommend me to build and use it?
And second: As far as I'm aware, when you launch HPR motors you need to stay at least 100 feet apart (30 meters) and the original build uses less length so, could it be changed to have 100feet of cable length to be suitable for launching G/H+ motors? And if so, any tip on how to do it?
As I said, my knowledge on electronics etc is really basic and ofcourse I'd love to just buy some e-matches, an "official" launch controller and go safe but the costs of building the rocket itself are pretty high and even tho I still need and want to spend some more money on the launch controller (ofcourse), I prefer to go for something that can launch HPR for this launch and future ones, and that doesn't cost me my hole wallet (also, I can't find them..) .
Thanks in advance for any help, info and tips provided.
Take care and have a good day!
