First of all, sorry for my bad english!!!
I'm going to put a external dump-valve on my LET. Just put on a phase 3 from EDS-germany. They also sell a dump-valve, but I have got one laying arround here.
It's a TAS piston type(adjusteble from 12 to 36 Psi) I got it at ISA racing in germany. (long time ago) It say's on the manuel that TAS is englidh.
Does anybody have expirience with this type of valve??? Or should I get another one???
