Hi Joe,
I saw that you finished a RUBIN II two months ago,did you flew it allready?,can you post some pictures?,i remember seeing the ad of Pica/Robbe inside RCM about 12 years ago and telling myself what an awesome,elegant and cool looking plane the RUBIN is.The sleek lines of the fuse and misile like apearance made me crazy about Pattern flying.
Do you know where i could get one of these?,or if someone here has one please let me know,as i have my old YS120FZ laying around and she`s begging me to bring here to life again lol
,but i`am not that skilfull to build a kit yet so ARF would be ideal.
Sorry i can`t help you with the proper c.g location.
Good luck with your cuest to find the plans for this bird.
Greg.
