Sig senior ready to soar
 

Thanks for the help and the words of encouragement for my sig senior guys, as of this weekend it is all covered and repaired, I taxied in the back yard really slow this afternoon and everything is functional. Next weekend will be my maiden flight (with instructor of course), if all goes well
in the next few weeks i will be ordering the engine cowl and the proper front windshield from sig.

on another note i was given a seniorita with 2 wings (one with diehederal one without) niether have ailerons, fusealage and tail feathers are damaged but i ordered a fuselage kit from sig.
also no landing gear.

i would love to convert this plane to a tail dragger but how do I do that, I would also like to add ailerons but don't know if i should go with strip or barn door type, making the modifications isn't a problem if I can see a picture of the mod i can recreate it. Or should i leave it alone and fly it
as R.E.T plane. with a trike.

I know a lot of people disagree but I vote for barndoor ailerons. I think they look like they belong on the Kadet Sr. and Seniorita. They are a bit more work to make over strip ailerons, but I think on these slow flying planes they work a bit better. And most of the radio's today will allow you to dial in differential aileron reducing adverse yaw.

Strip ailerons work just fine on the kadet series and are much easier to mod.

RE: Sig senior ready to soar
 

This is the mod to my Kadet. 50% dehidral and 2" ailerons. Works just fine.

50% ??? What the heck does that mean??? That's not how you express amount of dihedral. Degrees, inches at the tip but not %.

RE: Sig senior ready to soar
 

He probably meant 50% of original specs.
Mine is 1/3 of original.

RE: Sig senior ready to soar
 

I can accept that.

i am going to go with the barndoor ailerons like flynite, i was thinking six spars wide and
1 1/2 inch chord, (i think that is how you say the length please correct me if wrong). also
i am modding the tailfeathers with a digonal cut in the rudder so it can set flush over the
elevator. i don't like the looks of the elevator hanging so far off. will i still be able to make my tail dragger? i was thinking of running a seperate linkage to the tailwheel, I am keeping the plane light by running HS81 servos for the ailerons and throttle. and i have and older os.35 with a davis diesel conversion. i love the way it sounds and runs.
i had it on and airboat and it was a reliable and powerful engine.

RE: Sig senior ready to soar
 

If you are going to make that much of a change here is another thought.
Split your elevator and extend your rudder down so you can hook your tailwheel right into your rudder, no need for a seperate servo.
More than one way to skin a Kadet :D
PS: even if you run a detatched tailwheel you really don't need an extra servo, just run another control rod from your existing rudder servo,

RE: Sig senior ready to soar
 

The last thing you need to worry about with a senior is servo weight.

HS81's are simply not enough for the ailerons, although they should be OK for throttle. You would probably be able to use 81's for slow easy flying, which is really all you could do with the engine and airframe you have chosen, BUT you risk stripping them if the wind comes-up while you are flying, or even a hard bump in the car on the way to the field.

I have the ARF, not the kit. This plane is a blimp. You could add POUNDS of weight before it would be an issue, even with that engine.

Go get some standard servos for 15 bucks and scratch the $30 HS81's.

Enjoy the plane. It's the best trainer ever, IMHO.

RE: Sig senior ready to soar
 

age this is the seniorita that i am working on. the senior is going to stay stock for quite some time. thanks for the advice though. nice to see people looking out for me. i have the ARF senior which ws just completed, and a seniorita that is on the bench now waiting for some winter love. it will be my second plane and i love to build stuff so that is why it is getting so many mods.

RE: Sig senior ready to soar
 

It'll be fun, I hope. Still, even with the seniorita, the 81's are really best for foamies and light electrics. Darn good servos, but not really best suited for this application.

Just my opinion, of course. But then, I like fast high-torque servos and LOTS of throw. I'm sure the 81's will 'work', but I don't think they will be as durable as a quality standard servo would be. It might be best to save a bit of weight somewhere else if you have an option.


Good Luck and Have Fun!!
