hey shawn I have a new WS also. when are you going to break yours in? what plane you going to break it in on? I am breaking in my little DZ 70 and it spins a 11x11 Stock APC at 11,500(rich) on 20/20. The 11x13 is 10,000 (rich) on 20/20 also. I will need to get an airframe running to break in the WS while building a plane for it.

looking very nice! That thing looks fast just sitting there. I like the internal linkage, do you have any access to it after assembly? Just thinking about getting by tech and future maintenence.

I have done a lot of internals like that and if using good quality hardware and the proper set they last for a long time. If you develop slop then you can always cut in to it and replace hardware. The wear and tear is very little this way compared to external. External ones ware faster due to the oil from the engine and the dirt/dust kicked up from the wheels. Oil and dust combined make a great cutting/grinding agent which will have your stuff go bad very quickly.

Jeff, my thoughts exactly. As far as tech inspections go, I will keep some pictures to show Sergio at SAMs and I'm one of the tech inspectors for the triangle series so my airplanes always pass lol. Everything will be locked together with JB weld and I'm using the Dubro Cleve's with the positive locking tabs. I doubt it will be an issue. All my previous airplanes had internal elevator linkages. One logged close to 200 flights. Over the weekend I will be able to get the fin and stab mounted and hinged. I see no reason why she wouldn't be ready for paint by next weekend. Once that starts there will be no more pics until it's finished.

Wow, 200 flights on a sam plane? You are my hero! I got two seasons out of my silver plane and thought that was a miracle. It gets ugly out there sometimes. I just did my linkage external because I didnt want to put an inpection door, I guess I should have asked if pics would pass tech.
Jeff, is Ron going to call for you?

Over the past few days I was able to get the wing hold down hardware installed, the stab mounted, elevators pushrods finishes and hooked up and a few other items. For the first time she is standing on her own legs. That 14" prop looks huge! I need to carry it into work and get an accurate weight. To me it feels close to 5 lbs.

I like the aluminum hard points I did the same thing. Are you going to paint reveal on the hardpoint or stop it at the O.D. ? Trying to decide which is best. I could only dream of 5 pounds, I am going to be closer to 8

I will most likely just tape them off. I may be a little optimistic about the weight but I'm pretty sure 6.5 finished weight is a reality. I still have rudder linkage and tail wheel to go. I'm hopeful that I can get the CG back another 3/4" after the addition of those items along with the elevator halves.

Thanks Eagle, with 520 sq in I can't imagine it would have good landing qualities anything heavier then that. I really hope the the big prop will provide some breaking. The last one this size and weight that I built was a bit difficult to slow down. Then again it was running an 11" prop that would not idle down below 3K. The 115 is swinging a 14" prop and will idle down to 2K. I think I could have moved the CG back a little farther on the last one too. Time will tell, I'll just test fly at a local field that has a mat runway and flat for miles around. Been working on the fin, rudder image and tail wheel this morning. Imagine the rudder in a torque rod arrangement that exits the bottom of the fuse and then has a wheel attached. When I get it installed I will publish a picture when it's far enough along. I was thinking about internal linkage on the rudder too but there just is not enough room, I will just have to keep it in close to the fuse.

I have done the same thing myself on a plane as far as the tailwheel. It does work but that torque rod has to be able to handle the stress of both the rudder and wheel the mounting has to be bullet proof.

When I post a picture of the setup you will see it is pretty bulletproof. My bud JR came over today and we cut him some wings using my airfoils for his new airplane. I'm sending him home with my vacuum system. I keep asking myself why I would help out the competition. LOL. The reality is it feels good to pass on some techniques.

I always enjoy when I can look up and see that I had a small role in other racers' successes. Or, even just to say, "Yep, that one's got one of my cowls, that one is flying my wing; I pulled the canopy for that one, etc." I guess it makes it even a bit more of a "family" feel for me.

One of the great things about this hobby is that everybody is willing to help others.
Which is pretty cool because my latest project has me in water way over my head, and it only the help of others that has keep me going.
