Status: offline 		Thanks for the pictures Mike

I'm slowly getting the whole plane stripped down and reglueing all the joints. I'm putting an order into the the LHS tonight with everything I need including mounts and covering. Once I get into the covering process I'll get back to you.

Thanks again Mike, you've been very helpful.

Robert

Status: offline 		Back sooner than I thought. As I plan on adding the flaps any idea what to use? I was thinking either 1/8 ply or 1/4 balsa. I can't get bass wood from my LHS so that's out. another question about you servo mod. can you get me some close ups and do you mount the servo os the horn is ob the outside?

Status: offline 		For flaps: The only way to get really effective flaps is to enlarge the control surfaces. If you were to add another servo to each wing half and cut the stock aileron it would not work. Because there is such a large wing area you need all the control surface you can get for roll control of the bird. Now you could try it with and enlarged rudder and either fly with both (like you should any way) or mix it in with your radio. I would stay away from flaperons. When I tried them on my STM I lost almost all roll control and you need it when your trying to land.

What I did for flaps is remove the stock trailing edge of the wing and glue it to the stock aileron surface as you can see in the pictures. Then I had to rebuild the trailing edge of each wing half and lengthen the outboard part of the wing to match up. It was a ton of work but I have TONS of control during flight and flaps that slow the bird down to a crawl. Now playing with the flaps caused my last crash so be warned.

I'm not sure if you want to take on such a big project like making the surfaces bigger and honestly I don't think you will need flaps. If you fly where there is a breeze most of the time then you don't need them. If you are planning on flying off a small runway then they would come in handy but it takes some skill to get us to flying with them.

For the rear servo mounts I used light ply (1/8th inch I think), cut strips about an inch wide and glued them to the inside of the fuselage sides top and bottom both sides running between the formers. I also made a hatch on the bottom to access them and the connectors which reinforced the tail a bit. The flat balsa that is glued on either side of the servo left and right is really only there to have a place for the covering to stick to. Looking at things more I'm going to close in the aft part of the tail to make it look better and to add some strength.

Status: offline 		I'm putting together the 94" Hobby Lobby Senior Telemaster ARF, and I got a nice fiberglass Cap style cowl for it from Fiberglass Specialties. I want to paint the cowl the same yellow color as the fuse of the airplane itself. Does anyone out there have any info on what paint color (brand, number, shade, etc.) would match the Cub Yellow on the plane? I called Hobby Lobby, but they were unable to suggest a paint color that would match. My other options would be to use a different color paint, and extend it onto the fuse using my own pattern; or I could try covering the cowl with multiple strips of the yellow covering material. Any ideas?
Thanks.

Status: offline 		Cub yellow monocote or ultracote are the closests I have found to the factory covering. If you have the money and time do yourself a favor and recover the entire bird. Your going to end up doing it sooner or later because the factory "covering" is impossible to work with.

Status: offline 		Thanks, Mike. I agree with that covering issue. I had another Tele ARF and after about 10 flights the covering on the horizontal stab started to peel off (even though I had gone over the whole plane with an iron)! On the wing where I installed strut hardpoints attached to the spars, I had to apply pieces of covering to my work. That covering was a pain to work with! Since I haven't flown this new bird yet, I'll hang in there with the factory covering this season, and maybe re-cover it as a winter project.
I've looked at Cub Yellow Monocote/Ultracote and it doesn't quite match.

Status: offline 		Mike. I see on your Tele you mounted the rudder servo in a vertical position. I wanted to install rear mounted servos on the ARF version, but I didn't like the appearance of that vertical servo sticking out the side, and the control rod sitting on top of the stab. What I'm thinking of is installing a pull-pull cable system for the rudder, with the servo mounted in the usual "trainer" location in the radio compartment. I am also wondering if mounting elevator servo(s) in the tail would throw off the balance too much. (It's a big long fuse with a lot of moment.) What's your thoughts on these servo placements?

Status: offline 		Yeah the covering isn't quite the same color but it's really close. If your set on cub yellow and are planning on recovering the bird anyway then I'd get a can of the monokote spray paint for your cowl.

This is the second STM that I have built/owned. The first was the kit version with tail mounted servos. The main reason I did this was to free up all the space under the wing for a bomb drop. My kit version had one servo mounted on the side of the fuslage and the rudder mounted on the bottom. A pull-pull configuration would work great if you could get the cables around the elevator survo in the tail. Depending on what type of power plant your going with will depend on how the CG falls out with the servos mounted in the tail. My STM is electric with an 8000 mah pack to power the motor. I don't have any problem getting the birds CG correct and have about another 2 inches of space to move the pack forward.

My STM is a beast and much heavier then the stock one due to all the changes and reinforcements I made to it but it still flies and crashes like a champ!
