Lee Van Dyke Look at my sight and you will see how I used the plans holes through the spar for locating the pushtube and used a bellcrank to both transfer the action and de-tune the sensitivity of the elevator. I used 5/8 diameter 6160-T6 tubing from AS&S and end inserts for the run from stick to bellcrank. From the bellcranks to the elevator, I went through the hole already there from the cable and connected to the bottom of the elevator. AS&S sells a fitting that fits into the end of the 5/8 tubing just fine and can be cross bolted in place or riveted, your choice. The length of the run on the standard KR2 requires at least 1 inch diameter thin wall that must be adapted down to your connection fittings. AS&S has a chart that I used for ordering tubing. Any run more than 5 feet in length is going to need at least 1 1/2inch diameter tubing for the compression strength necessary for proper safe operation. Both the Thorp T-18 and RV series aircraft use these sizes trouble free. If in doubt go with the next larger tubing size. Dana Overall has a parts list if you ask nicely that I am sure he will e-mail you on parts to make a safe tubing for the KR. If you have an S model with the longer fuselage, you will definitely need to go with the larger diameter tubing, and then adapt it down for your fittings. The other questions you have can be answered by studying Mark Langford's site, mine which is ideas taken from several others, and on down the list. Study there first and you will save all kinds of time asking questions and wracking your own brain trying to figure it out.
