If your aircraft has a pull-type starter, installation will require some modifications:

Your pull starter mechanically engages the starter drive while simultaneously supplying power to the starter motor. The Sky-Tec C12ST2 engages electromechanically so you must do two things:

	Order the "kit" (KCST2) which includes a C12ST2/S starter, push button, wiring harness, STC's and instructions.
	Replace your pull-start "T-Handle" (or knob) with the push-button switch and wiring harness in the kit.
	Cut-off the shaft in the rear of your engine upon which your pull-starter's pinon gear used to ride. This can be done by following the STC modification instructions.

If your aircraft has been previously converted from a pull-starter:

Ah, this one's easy! Just order a C12ST2/S from your favorite dealer, install and enjoy (we even include the gasket). The /S will be a "short-nose" starter that will clear the previously cut-off pinon gear shaft inside the rear of the engine.

Safe for ALL TCM starter adapters!

ST3 series starters were engineered with the following design features:

	TCM Starter Adapter "friendly"
	Incredibly low weight (only 6.5 lbs!);
	Mild 1.4 kW motor coupled with aggressive gear reduction for high torque, moderate cranking RPM & low current draw;
	A patent-pending, common-sense design that eliminates the majority of "broken spring" scenarios that occur so frequently on "improved style" TCM starter adapters;
	Nearly instantaneous release of the starter adapter wrap spring virtually eliminating starter-induced adapter wear;
	Safe & approved for ALL starter adaptors ("classic style", "improved style", "permold", "sand cast", etc.);
	A simple, easy-to-install, bolt-off/bolt-on, maintenance-free starter that fits the entire "large" series Continental engines (with right-angle starter adapters) from O-300-D through TSIO-550 engines;
	Highest torque possible with minimal current draw - perfect for aging Cessna singles with tail-mounted batteries.
	Attractively designed and affordably produced making it the first and only choice in lightweight large Teledyne Continental engine starters.

Safe for ALL TCM starter adapters!

ST5 series starters offer the following features:

	Powerful 2.2 kW high-torque, permanent magnet motor
	Faster cranking RPM - typically 10-25% faster than heavyweight starters.
	Light weight (9.4 lbs!);
	Proven gear reduction drive train tempers current draw;
	TCM starter adapter friendly electromechanically engaged/disengaged drive system provides instantaneous release of the starter adaptor wrap spring virtually eliminating starter-induced adapter wear;
	Approved and recommended for ALL starter adaptors ("classic style", "improved style", "permold", "sand cast", etc.);
	A simple, easy-to-install, bolt-off/bolt-on, maintenance-free starter that fits the entire "large" series Continental engines (with right-angle starter adapters) from O-300-D through TSIO-550 engines;
	Attractively designed and affordably produced making it the first and only choice in lightweight large Teledyne Continental engine starters.

If your aircraft was manufactured with a push button (or mag switch) starter:

Another easy one. Order a stock C12ST2 starter from your favorite dealer, install and enjoy. We even include the gasket! The C12ST2 starter has a small dowel boss on the nose of the starter that will reside within the needle bearing inside the rear of the engine. The only purpose for that dowel is to keep your bearing needles from falling out. There is no need to pull the bearing.

How is the ST3 different?

The ST3 starter incorporates an innovative clutching system which enables the starter to engage the TCM starter adaptor while powered and completely disengage the powerful permanent magnet motor while the starter is unpowered. This positive disengagement allows the TCM starter adaptor to fully unwrap under all normal operating conditions thus greatly prolonging starter adaptor life.

How is the ST5 starter different?

The ST5 starter couples a high power 2.2 kW motor with an innovative solenoid-engaged (and disengaged) drive system completely disengages the powerful permanent magnet motor while the starter is unpowered eliminating possible TCM starter adapter wear while providing authoritative, high-RPM starting. Positive solenoid enabled engagement and disengagement allows the TCM starter adapter to fully unwrap under all normal operating conditions thus greatly prolonging starter adapter life.

What if you're unsure which engine you have?

Take off the accessory case on the rear of your engine. Look inside, toward the top most area of the cavity. If you see a hole (actually, that's the inside of a needle bearing), order the stock C12ST2. If you see a flush-cut shaft, order a short-nose (C12ST2/S). If you see a shaft, order the KCST2 conversion kit.

How do I know which one to buy?

This one is pretty easy! If your TCM engine has a right-angle starter adaptor at the rear of the engine and a battery some distance from the starter, chances are this starter is the right one for your application. Consult our extensive aircraft fit guide just to be sure.

How do I know which one to buy?

If your TCM engine has a right-angle starter adaptor at the rear of the engine and a clean source of nearly located battery voltage, chances are this starter is the right one for your application. Consult our extensive aircraft fit guide just to be sure.

	"Someone told me to never install a permanent magnet starter on a TCM starter adapter!" Ah, the amazing Mis-Information Super Highway... Sky-Tec developed the ST3 and ST5 to satiate customers who may be concerned their particular TCM starter adapter may not be completely compatible with the new generation permanent magnet starter motors. Many of those customers have experienced repeated starter adapter failures with TCM "Iskra" starters and are seeking a more reliable and starter-adapter-friendly design. This is it. Both the ST3 and ST5 starters utilize a powerful permanent magnet motor, but we also incorporate unique methods of releasing the engagement ensuring there is minimal drag on the starter adapter input shaft after power has been released from the starter. We are confident you will find both the ST3 and the ST5 provide many years of reliable service for all types of TCM starter adapters.
