No, sorry, not really - only playing with the content samples (meaning I’ve put already made emitters in a level and watched them go)
ok, l’ll search around. I would like to pull off this concept I have for this game and Unreal is a much better platform than I had before. If there’s any other blueprint tips & tricks you can share I would be grateful 
Oh, how do you change between variables in runtime in the blueprint. In C++ it would be be through an IF block or possibly a matrix to hold each value and reference it based on player actions. But I’m not sure the best way to do it in blueprints.
There is a “Switch” node and also a “Select” node that you’ll come to love - for instance you could create an ENUM of your thruster values “Basic”, “Upgraded”, “Super Duper” - and then plug that ENUM into a select and then it’ll give you pins to plug your variables into to pass on depending what value was selected - I’m not explaining it very well but try to look up “Select” and “Switch” nodes 
Here’s a quick mock up of what a Select might look like for an idea
