Dear Brothers

I am finally getting around to assembling my TOC 30% Yak and am at the point of installing the rudder and linkage / control wires........... Does anybody have pictures depicting where the control wires exit the fuselage? Thanks all!

Hello Mo

Take a look. There are holes or slots under the covering under the horizontal stab. You need to find 'em and open them up a bit. Do not just cut a hole and pass the cables thru. You do NOT want any rubbing of the cables on the fuselage because eventually one will snap, and then the rudder will explode itself fluttering to death - at which point you have an expensive smoking hole in the ground.

I had to use a dremel tool to elongate the slots a bit to ensure no rubbing. Good luck! GREAT plane!! You'll love it.

Best,

Dave

Mo,

Just a suggestion. This plane turns out tail heavy in most cases if you are using an engine similar in weight to a DA-50. I placed my rudder servo far forward as possible. You may want to balance the plane with all equipment installed before deciding where to locate the rudder pull pull. Generally, the further forward location is better for this plane.
My 30% SD Yak is still slightly tail heavy even with 3 Li Ion battery packs on the motor box.

Thank you Jaketab

I'll be running the DA-50 as well but using 2(ea) A123's. This should help. Did you find that the Yak flew tail heavy at the mfg's recommended 6.5" aft of the wing leading edge? Thank you

Jerry

Can't say how it flys at 6.5 inches. My C/G is aft. Although tail heavy, it is still managable at 6.5 to 7 inches aft.
Also gave the motor slight downthrust..

I'll be getting one of these to replace my AW 29% Edge, and will be using a DLE-55. I've read back aways and have a couple of questions: For those who have used the DLE-55, will the stock muffler work inside the cowl or will I need a cannister? I see this comes out tail heavy and I've read that the tail wheel that comes with the plane is pretty poor. I have a titanium tail wheel from somewhere and plan to use it. The version I'm getting will be the "HD". Have the older "issues" been resolved? Is the spinner ok?
Thanks

This plane is no longer produced, what a shame. SD models kaput, and I think the company now is RC Pilot. I think the CF landing gear is the same on both companies yaks.
The stock tail wheel on the sd yak must be replaced for a good one. I don´t used a side muffler on mine, but I think it will fit fine inside the cowl.
For what I remember, you need to reinforce where the canopy is atached to the fuse. And I had to replace the firewall aluminium angles.
The spinner is heavy, and some people had problems with it. But the yak looks fine without it.
I have beated this plane for almost 2 years and it always came back for more[>:] Very strong plane with wonderful flying characteristics.

The plane is still in production. SD is now marketed by Thunder Tiger /Ace. Tom at Valleyview RC is making me a good deal on the combo!

Great to hear that!!! I need a new canopy.
Somewhere in this forum you can find a pdf archive with a lot of info about building and setting up this plane. But i don´t remember the exact page.

Vacaman

Sam, do you have Tom´s mail. The mail listed on the web page doesn´t work.
Thanks.

Are the RC Pilot 30% Yaks the same as this....SD,TT, etc? I am specifically interested in the CG....somewhere in this forum someone states that the plane should balance by holding the wing tube( without the wings on), and that the nose should be down about 3 degrees. Any opinions please? By the way the new RC Pilot planes are beautiful and really well done, with the exception of no up to date instruction manual....Thanks WC

DaddySam

My Feedback: (9)

The manual that comes with the new Thunder Tiger Yak says to start with the CG on the wing tube. It does not mention anything about removing the wings to check CG. I'll most likely start with that. Guys on the thread have been saying that 6.5" is a good start point and many have moved it back. Is it the same as the Pilot yak? I dont' know, although I've read that somebody who left SD started the Pilot line, and my tank has "SDM" (I am assuming that this is "S.D. Models") on the side.

DaddySam...I got my RC Pilot 30% Yak from Chief Aircraft, but Troy Built Models also carries them and they state in the intro to the RC Pilot planes about the current planes being made by the old SD people....something to that effect. But no one seems to have an updated manual...........Thanks for the info about the CG, that is a big help......WC

Hi Guys,

I found the thread compilation that was put together a while back. Enjoy!

Hey all yak owners.. does anyone know if the black stopper that comes installed in the fuel tank is gas approved, or do I have to switch it for a brown one that i know is gas approved??
Thaks much

DaddySam

My Feedback: (9)

I would "guess" that it is set up for gas, but I ended up using a Sullivan tank with a Dubro stopper so I could put the tank in the cannister tunnel. If the stopper starts to degrade, it seems like it would ruin a days' flying when you discovered it...
Sam

You can use the stoper that comes with it. The plane was designed for a 50cc gas engine. No reason for them to give you a stopper designed for glo fuel.
Good luck with the plane I have had one for about 3 years and it is my favorite plane.

Edward,
What have you settled on for your CG? Just curious, as there seems to be a range of 6.5" all the way to 7.5".....
Thanks
