Due to popular request, I've just had these square Lipo weights made that will fit sweetly into the YZ-2! Available in both 50 and 80g for just £8 with free postage.
Can't quite remember who messaged me so thought I'd pop it in this section. If you have any other YZ-2 specific weights you'd like making let me know!
