Tracer 2 Meter is here!!

[Konrad]

Yep. The smaller HS is more than adequate but the gears are a bit delicate for most landing zones so I’d stay with the bigger x10 mini for the robustness of the larger gear train. I strongly recommend external bearing servo trays.

P.S.
I see the wing surface is smooth. So I’d go through the extra effort of adding the IDS drive.

 

[Jakob]

Thank you so much.

 

[Jakob]

What do you think is the equivalent MKS Servo for those x10s?

 

[Konrad]

Are there any? The 6110 with the bushing output and plastic case are a distant second to the KST servo and a bit more expensive. The higher end MKS are great but at close to double the price I don’t see the value in them at these speeds.

 

[Jakob]

Yeah, that's true thank you for all the info I appreciate it.

 

[Wayne]

The MKS 6130 family would be similar, but like he said comes at a price:

MKS HV6130H Wing Servo - 8.1 kg (112.49 oz-in), 0.10 sec - Wide Voltage

HV6130H (0.10 sec/60° - 112.5 oz/in @8.2V)

With the older 4.8v to 6v servos what are you using as a battery?

 

[Konrad]

Supplier of said good batteries?

 

[Wayne]

Looks great, can't wait to see her out in the wild!

 

[Konrad]

“Professionally built”?

What defines this? I assume it means you paid others to build assemble your model. Is there a quality standard that a builder must meet to be “Professional”?

I’ve seen many of your builds and can say they often lacked for nothing.

I received the Tracer yesterday. I had it professionally built.

It has a pair of KST X10 Mini for the flaps, a pair of MKS DS6100 for the ailerons and a pair of MKS DS6125e for the v-tail.

For power there is a 4-cell 1500 NiMH battery and a FRSKY V8R7-II receiver.

All surfaces are tight and slop free. The flaps deploy a full 90 degrees and the wings are plug and play with glued in deans pin connectors. Slots were cut in the wing surfaces for the aileron and flap linkages and a slot was cut into the end of the fuse for the v-tail ball links.

The fuse is very tight and a ballast tube was not installed. There is room for ballast in the wing. A custom wire harness was made to save room and the receiver was modified to optimize for clearance.

The AUW is 54 ounces with the CG at 94mm. A few ounces of lead was added to the nose for balance.

This is a really nice looking model. The fit and finish is very good, the wings and tails are stiff and solid, the gaps are tight, the paint is vibrant and shiny and it feels bigger than other 2m models. A larger joiner bar with room for ballast would be an improvement. Over all I think this plane is a really good value for the quality and price.

I am looking forward to flying it.

Very nice Adam. Hope you bring it to Banos, I’d love to see it.

Lenny is a known quantity.

 

[Hill Hobbit]

Very nice!

 

[Wayne]

But Los Banos is sooooo far away!

 

[Kentish]

Good evening.
A question for Wayne…
Are the slots in the back of the fuse’ for the tail control horns (?) pre cut on the ones you got in the US?
I got mine from T9 and they are not cut.
My build basically stopped at this point a couple of months ago as I’m not sure (too scared) where to cut.
Cheers

 

[Wayne]

Not cut on ours either. Basically put a little masking tape over the area, then slip on the V-tail and mark the hinge location onto the tape. The hole will need to be from that hinge location and back a few MMs. Start small and test fit often. Remove enough material so the torque rod has smooth operation. Should not be too bad. A dremel tool with a small grinding cylinder should help speed things along.

 

[Kentish]

Thanks Wayne.
Weather looks to be crappy here over the weekend so I’ll crack on with this.

 

[Bundok]

I’m going to be ordering and building up this tracer. Be my first glider build. But have no clue on what servos will fit int the glider. Here is what I’m currently looking to build it out with. Can anyone give me the thumbs up if it’s the right guts

- KST X10 minis for flaps and Ailerons. (Minis the best choice or will the regular KST X10 fit?)
- KST X10-710 for tail feathers.

Will these fit?

Also if I were to build with the lDS what size would I need? What benefits besides looking super clean does the lDS offer?

Thanks I’m advance

 

[Konrad]

If looking at KST, I'd look at the HS08a for the ailerons easier to fit in the thinner tips. The X10 mini for its larger gears than the HS08 but the same size gears as the X10 for the flaps, for the tail flippers the A08.

True IDS offers a lot of in the way of more bearing area at the spoon (control horn) and servo arm. This results in a lot less wear. They also control the play in the servo output shaft, with the external bearing. Making for a much more rigid control system at the same time extending the life of the servo gear train. The only down side is that the control hinge needs to be of a slop free construction. And if the model has been preped for the classic control horn there is a high probibility that the wing skins are damaged adding drag and noise that the IDS can't correct. I can't for the life of me understand why molded OEMs are still mangeling wings with the "classic" control horn set up!

You lost me with the IDS size question. These are sized to the servo you choose. Are you asking about arm length?

Take a look at this thread for more on the installation of the IDS.

The big question is what radio are you using and do you know how to program it for camber changing and Crow/Butterfly?

 

[Wayne]

Just took a closer look at the model.
I like the X10 Mini for the flap:

KST X10 Mini Wing Servo - 7.5Kg (104.16 oz in), .09sec - High Voltage

If the X10 is physically too big and the X08 is too low on torque the X10 mini might be just right. The X10 mini, like it's bigger brother the X10, sports an improved motor controller that's driving a coreless motor which in turn is spinning a minimal bac

The aileron bay is large enough and deep enough to handle a 10mm thick servo like the X10 Mini. (measured 9.78mm deep at the bottom of the pocket) But will be a little easier with the 8mm thick servos like the X08, X08+, HS08 or A08. So plenty of options there.

KST A08H - 3.2Kg (44.4 oz in), .09-sec 7g Wing Servo

KST presents the KST A08H, another great performing servo for a variety of uses. It may look similar to the well favored X08H, high voltage capable and with an 8mm thickness, but that is where the similarities end. Inside the CNC machined case is an upgraded set of gears, made with even tighter...

Fuselage would be fine with the 8mm servos as suggested by Konrad, or you could also go with something like a KST 315:

KST DS315MG Servo - 4.8Kg (66.6 oz in), .07-sec - High Voltage

KST has yet another awesome servo with the DS315MG. It is blistering fast even when run on 6 volts. A great servo for applications where high speed, precision and strength are needed.MOTOR TYPE:12mm CorelessSERVO TYPE:DigitalGEAR TYPE:MetalSTALL TORQUE2.8Kg.cm (38.88 oz-in)@4.8v | 3.5Kg.cm...

(I like the speed of this servo and similar sized servos for elevators.)

If you wanted to save weight you might focus on using just the HS08 or A08 family for every surface.

Lots of options.

Hope this helps.
