do you have to cut the springs for it to cycle correctly? i put a regular guarder sp130 inside mine and the piston jammed in the back of the gearbox and got stuck, every time. i just want 480ish fps. what spring should i use and do i have to cut the spring for it to cycle correctly?

what springs are you guys using because with the guarder sp130 it wont cycle forward it gets jammed back.

poor quality but its what my phone can do

well with the stock spring my sectorgear is missing a tooth and my piston is shreaded..... i got 2 of each on the way but i think i might just stick to stock power lol.

i just received mine and have been trying to install a Guarder SP130 in it and when i fire the piston gets stuck at the very back of the on the spring guide. I cant figure it out. i have the second version of the Svd. Are there certain springs that dont work with the svd? Is there a Trick to it at all? also when i install it i seem to get a bow the top of the gearbox very very slightly? is this normal or should it just fit no issues? im trying to get X < 500 fps so i think the 130 should do it right?
