This is the RMS for the 29/40-120 case yes? Assuming yes, buy the -8 and use the delay drilling tool to take it down to 6.Does Aerotech have plans to make a G64-6? 8 is too long for some rockets and 4 is too short. Flew a PML Mini BBX on a G64-4 and it was too short (needed a 6). Being quantum there was no damage but how long will that last?
I tend to always buy the longest possible delay and then drill for the specific flight.
If we are talking SU (non DMS), then this doesn't apply...
