Hi Ed! Thanks for that :). I did search around and found HPM in Singapore sells the Mk65s with high speed tails (3D printed) :). I’ll take a look at MPM too.   I’m now considering whether I am overloading her! Frank @bentwaters81tfw suggested a RATO so I am thinking that one through now. I have these for the ‘jet but I think it is a different configuration. If I can find the bottles I might try to build the rack for them.    Keep safe!   Martin
