stock piling will help you some but you will need to buy new stuff anyway.
I got a new high end radio because of fear of inflation and intend to buy some more servos, now to sell my 72mhz Rx's for pennies doesnt make much sense maybe to keep them.
I grew up in an economical crisis - bad inflation you have some money but you just cannot spend it on toys.
the whole idea of raising customs, prices and devaluation of our dollar is to protect the local industry from foreign cheap exports to the US.
yes in inflation the prices of used stuff also sky rocketing....
what I'm doing is thinking going electric and for sure not investing in any new glow stuff motors or airplanes, for me gas or electric from now on.
Dont worry who wants to fly airplanes will find a way to do it - my CL planes were covered with supermarket plastic bags.
