I'm not for certain....but I believe jrf would be the one and only Jim Feldmann?? Hi, Jim!

Jim's RCM twin sportster was a great RCM plan design back when and his new 90/120 size looks to be a real "go-getter". You just may want to consider drawing up some design changes/ instructions, Jim, for those who want to build their Super Sportster as a sharp looking twin. Can't wait to see your model finished!

BTW: LOVE that Knockabout...flew the "u-know-what" out of 'er last summer and fall and that plane still looks like new. Lots of nice comments on both the looks and the flying ability of your design.
