Krytak SPR

[AirsoftUK]

Krytak SPR (UK) come with weaker  spring and 20k motor, whereas the US version comes with a 30k to compensate for the stronger spring.

Was wondering if I buy 30k motor and  a stronger spring, would using an 11.1v lipo cause overspin making semi fire 2 shots ? Or should I just upgrade the spring, keep 20k and use an 11.1v / upgrade motor to 30k & stronger spring and just use a 7.4v lipo. 

Basically I want a DMR?? Send help.

I had same prob in my lvoa i think it had a m 90 or m95 in it . I put a m105 in but it made it slightly hot so i have had to clip the spring . But even clipped it has stopped the over spin /double  sooting on semi. Given the extra barrel lenght on the spr maybe go for the m100 and it should sort out your issues
