RE: Impact
Hi Andy,
The stern former hasnt been installed along with the depron brace. I only fitted the brace temporarily for the photo. I am currently setting all my incidences which are now perfect. It has taken some work as I found that the markings on the fuse are a fair way off.
Even the advice they gave about the 37mm below the centre of the tailplane tube does not result in a line that is directly in line with the engine cowl flange. The jig allows you to check everything perfectly. I would not reply on the seam line at the front of the fuse as being centre. I found it the be of to one side by 3.5mm. By having a centre line directly down the centre of the jig, you can position the fuse exactly by marking certain points along the jig base. Run a set square along the fuse and measure the distance to the centre line. Do this to both sides and make the distance equal.
I am happy with the alignment now but it would not have been possible without the jig. Hopefully I can glue everything up tomorrow.
I have also replaced the supplied wing tube with a PBG unit Frazer Briggs sent me. This new tube is 34grams lighter and much stronger. He also supplied a outer tube which will replace the part which is glued into the fuse. They are a perfect slide fit which will eliminate most of the slop.
I will be painting the IMPACT exactly like my Alliance except replacing silver with gold.
Here is a photo of the alliance.
