Next I cut a 1/8"x1" plywood block to fit in place over the 3/8" block on both sides of the rudder front and glued them in place as well with 30 min epoxy. I then Clamped the blocks in place to dry overnight.

Status: offline 		After the blocks dried overnight, I sanded them flush with the cap strips on t7 and t8. Then I drew a straight line down the center of the leading edge (close enough) to begin shaping the bevel. I also marked a reference line on the end of the leading edge to act as a guide to shape to. Next, started shaping the bevel with a block plane to remove most of the balsa and rough sanding to the angle with a bar sander. In pic #3 you can see that all the bevel could not be shaped using the sander or the block plane, so I made a back cut with a razor saw and carved the remaining bevel tips out with a hobby knife. This is the same as when I did the elevator bevel. The end result came out pretty good.

Status: offline 		Next I placed the rudder and the Vert/stab on the plan and marked the location on each for the hinge doubler blocks and glued them in. I also rounded the leading edge of the vert/stab.

After this is said and done, the rudder I mean, it dosn't appear my concerns of the thin trailing edge and the rib attachment were with any merit. The rudder seams to be pretty strong as built. I still think, however, that Midwest could have done a better job of laying out the sizes on the ribs in the rudder.

Status: offline 		Finally got back to the shop, I had to break for a few days to fly, the weather has been fantastic.

Well I screwed up but "I think" I fixed it right. The first pics are of the horizontal stabs lined up on a straight line and you can see in the first pic that everything seem ok, but wait. The back side has a 1/16" to 1/8" gap. So what I did is took a piece of 1/8" balsa and epoxied an end cap on the stab. Then sanded the end with the proper angle to fill the gap solid. I must have missed the end rib moving while setting the first top spars on the assembly. This looked like the most obvious fix to me, can't think of another way to do this. Any way, after sanding the end cap to fit, they lined up well and no gap. Then pinned one side to the board making sure to center exactly on the line. I glued the two sides together with 30 min epoxy and clamped at the tip to let dry overnight. Next step will be to shape the leading edge and fill and sand the rest of the surface.

Then I took another break to go flying. Be back soon.

Status: offline 		Just to let everyone know, I will be back to the shop soon. I had some things to take care of around the house as well as taking advantage of the great flying weather to maiden my first build. I will pick up where I left off shaping the leading edge of the horizontal stab.

Status: offline 		Hey there looks like your doing good so far . I just framed my extra 300 xs ,still need to fiberglass the wing joint and assemble the tail feathers to the fuse.Its a fast builder I think .Ok a few points to watch out for , if you haven't up graded your plans with the new addendum's supplied .for your sakes do it ,will save you some real probs later on .Oh before I forget this ,they show adding pins to the engine mount (wooden dowels ) but they don't show anything about doweling the landing gear plate .I added 2 per side to mine 1/8 !" dowels ,plus I also added some extra tri stock to the motor mount plate and box. Your right about the hardware its ok for a 60 -90 maybe???the tailwheel assy is really a joke all that will hold it in place is a hunk of fuel tubing Shakes my head I wouldn't trust this set up on a parkflyer *LOL*
As far as the 6-32 screws in the elevators coming loose a drop of thin ca will keep them tight as long as the planes around , but I did fill mine in also with some extra wood.cant hurt !
I was sort of angry that the kit did not come with decals nor cowl or pants ,not even a dash decal,For the price of this kit it should be more than a box of wood .
I'll be following this and looking to see if you have any more questions, if you need some advice and cant wait, you can email me at cyberwolf49@hotmail.com
I'll post a pic when I get the tailfeathers in place should be monday the 14th
Keep up the good work.

Status: offline 		Thanks for the info Cyberwolf, I will definitely look at the landing gear mount construction when I get to that point. So far for me it has been a pretty slow build at this point. I will be starting on the fuselage this week hopefully. Keep getting interrupted with daily responsibilities and work, not to mention the crashed processor. Thought I had lost all my data as I had the previous PC's drives set up on a raid controller. Turns out the new mother board was not compatible with with the Promise Raid. Had to get another loaner PC and set the raid drives up in it to retrieve data, all is well though. I didn't get any plan(drawing) addendum but I did get the manual addendum if that is what you mean. That is the first thing I did. I will be using the fiberglass wheel pants and cowling from Stans Fiber-tech. Your'e very right about the hardware and accessories in this kit, they are sorely lacking. I am looking forward to your pics on this build as well.
Thanks, Bob
