Integrated Drive System/Mono for the KST X10, X10 Mini, DS125, DS135 and DS225

Product Code: SRIDSM-KST-X10

Price: $14.17

Description

This updated frame has a larger gluing area and fits the KST DS125, DS135, DS225 as well as the newer X10 and X10 Mini servos.

The Integrated Drive System/Mono for KST DS125, DS135, DS225, X10 and X10 Mini servos is a beautifully engineered external bearing servo frame matched to a custom servo horn and supplied with a set of ultra-rigid pushrods for connecting the servo to flaps and ailerons. The Integrated Drive System/Mono is the latest design of Servorahmen IDS systems. It ensures an low drag slop free and mechanically sound servo to control surface connection.

An Integrated Drive System or IDS is a largely or completely internal linkage between the servo and control surface. It is different from a normal wire based linkage in using much stiffer components, resulting in a more rigidly connected control surface, with much less compliance. Also IDS linkages use much shorter servo arm and control surface horn lengths. This allows the linkage to be enclosed in the wing.

These frames and IDS linkages speed-up servo installation, keep the servo secure and rigidly mounted, and also allow easy removal for maintenance or replacement. The external bearing reduces side load at the servo output arm, reducing compliance and extending the life of the servo. The external bearing and the special rigid IDS pushrod reduces any free play, increasing the stiffness of the control surface, improving control and avoiding flutter problems.

The connection between the servo and control surface is made via a ready-made hard plastic pushrod, so no cutting or gluing is required, making for a quicker and more repeatable installation. 12 of these mono pushrods are supplied in each kit, varying in length between 48 mm and 81 mm, each approx 3 mm longer than the next. These new IDS sets are labelled "Mono" as the pushrod is a monolithic component, not an assembly of parts that can come apart.

Parts supplied in this Mono IDS set:
1 servo frame
1 control surface horn
1 ball bearing
12 plastic IDS pushrods - range between 48 mm and 81 mm length
4 servo arms of different lengths
2 servo mounting screws
4 steel bearing shafts (2 are spares)

Sold singly. Add one to the basket for mounting and connecting one servo. The previous type of IDS sets with pushrods made from an aluminium tube are discontinued and replaced by this new IDS/Mono design.

No official installation guide is available but Piere Rondel has posted this excellent Servorahmen IDS Installation Guide. Also this Horn Installation Drawing is very useful.

Review by: Steve

First time using these IDS system/mounts from Servorahmen. Initially disappointed that they come with no instructions and took some time to figure out how they are used.

The fit of the servo arm into the bearing/frame is a tight push fit. A tip from Hyperflight when using the frames for the KST X08 version was to warm the arm in a cup of boiling water. This certainly made the initial assembly much easier.

In the end for the model I'm building I've not used the aileron/flap spoons. However, the end result is an excellent linkage with zero free play so I'm very happy.

Instructions or a link to such would have made this a 5 star rating.

Spline Help

These are really nice frames and IDS. Rugged! I couldn't get the horn onto the spline easy. I found this thread on RCGroups that suggested a bit of heat and then they slid on with some pliers. Afterwards they worked nicely on/off while getting the angles correct. It doesn't take much heat, just a little.

Service Excellent

Used this system of servos and IDS before...why change something that's successful

Excellent product, no slack, no flutter. My first IDS install, and required a bit of forward thinking to make sure setup was correct before glueing anything. But the rest of the servo installs then followed suit.
Excellent service and delivery.

I had to modify the servo mount screw holes slightly to fit my X10 Mini servos. But other than very good - they work perfectly. Very precise.

Integrated Drive System

Much easier to install than I imagined it would be. Very positive, strong, exact, and an excellent product.

Difficult to install

The V3 couplers for aileron and flap servos are quite difficult to install. Its also easy to damage and frequently have to replace even with soft landing.

A really well thought out system. The two piece horn going into the control surface works well and the two little tags help to ensure that the horn is glued to the top surface and each one sits on the same line relative to the hinge. It took a while to get the first one fettled correctly but the following 3 were easy once the system was understood.
