Default RE: 12' Telemaster- gonna need help


ORIGINAL: JeffinTD

In a moment of bravery (or stupidity) I clicked the button and now the nice folks at Aeroworks are cutting me a kit. I built kits and a couple scratch builts, but that was a long time ago, and nothing close to this scale. Hopefullly I didn't bite off more than I can chew, but from looking at other threads and the directions it looks like a pretty straight forward and fun build.

Anyway, this will be gas powered (my first). I was kicking around a G-38, but Hobby King's 53cc twin is really tempting. I don't want to overpower what is intended to be a slow flying plane, but would like enough power if I decide to try towing or whatever. Smoothness of a twin would also be a big plus. Thoughts or suggestions?
The Zenoah's are great engines. The G-38 will provide JUST enough power to fly the plane, but don't expect to do anything else. If you are even thinking of consdering doing anything else with it, go with a DLE-50

Servo wise, I was slooking at Hobbico's HCAM0165- a standard size non-metal gear high torque double ball bearing with 83 in/oz tq for each half of the elevator, and the rudder. Sufficient?
83oz/in of torque should be fine for those. Personally, i would go with more torque and something not Hobbico. Hitec 5645's (for digital) or 645MG's (analog) should work well

For the big ailerons, I was looking at HCAM0205 1/4 size non-metal gear with 181 in/oz tq. Would that work? I was also eyeballing Hitec HS755MG with 200 in/oz tq...
1/4 scale "dinosaurs" are a thing of the past and a dying breed. They are big, bulky, heavy and typically SLOW. Go with the same servo's recommendations as above.

Control hardware wise I could also use some input:

I was looking at 4-40 rods threaded on one end with Great Planes soldered clevis on one end, and Dubro Safety Lock quick links on the other. I would guess those would be strong and reliable?
I never use Soldered clevis'. I've seen to many of them fail from improper solder jobs. I would personally use 4-40 solid threaded rod w/ a carbon tube glued over the rod (the rod runs in the hole in the carbon tube) between threaded Sullivan Gold-N-Clevis'

Hinges: I want removeable cotter pin type, and was looking at Durbo #257, but was wondering if I should use (or if there is) something larger?
Dubro's Giant-Scale pinned hinges should be fine. Personally, i would go with the Large Robart Hinge Points. They are easier to install, and are my hinge of choice

Control horns: I prefer T type, and may inlay the back plate or blind nuts prior to covering. Is the Great Planes Large Horn GPMQ3902 appropriate?
I prefer Dubro hardware over the great-planes stuff... http://www3.towerhobbies.com/cgi-bin...?&I=LXD937&P=7

Lastly wheels. I was looking at 7'' Sullivan Skylites for mains. Landing area locally is more weeds mowed short than grass. Plane will weigh somewhere around 23 lbs. These work? And, what size tail wheel should I be looking at.
I like the Dubro "Big Wheels". they are inflatable, so you can adjust the pressure for the type of surface you are landing on, and they absorb more abuse from those less than perfect landings:http://www3.towerhobbies.com/cgi-bin...?&I=LXD770&P=0


Thanks in advance for any help, and sorry about the long post. There's no LHS that would have most of this kind of stuff, so I want to get most of the components ordered soon (nice to have servos and stuff in hand while building).
