Carburettor Intake Bend ZG 38SC

Cast aluminium. With this bend fitted, the intake air can be drawn from the fuselage, effectively silencing the intake noise. The carburettor can be hooked up direct from the rear. The TITAN ZG 38SC runs really well with this bend, it also markedly reduces the fuel consumption.

The gasket #3803 will be needed and it is strongly recommended that the intake tube #0081 be fitted.

Intake Tube for Titan ZG 23 /38 /45 /62

This bell mouthed aluminium tube is permanently fixed into the Tufnol flange with Epoxy, it can be reduced in length should this be necessary. This intake tube, due to it increasing the intake tract length raises the power output and at the same time reduces fuel consumption in our preferred rpm range. The acceleration is also improved.

Stainless Steel Silencer for ZG 38SC This three chamber silencer for the Titan ZG38 is fixed behind the firewall with the four motor mount fixing screws. This silencer will fit practically any model that can be fitted with the ZG 38. This type of fixing of the silencer is not only very simple because no extra parts are required to fit the silencer, but it has the added advantage that the silencer and engine are one integral unit, which prevents vibration induced failure to the silencer.

There is seldom enough room under the cowl with a ZG38 for a large enough and thereby effective silencer. The best answer is to fit the tank at the CG position where it belongs, then use the free space behind the firewall for the silencer. With the ZG 38 this method is ideal due to rear exhaust outlet. To obtain sufficient cooling, cut a hole in the firewall the same size as the cylinder and right up to the motor mount. Seal off the air outlet at rear of motor cowl and add ducting between the cowl front and firewall so that all air coming into the cowl is forced to go through the cylinder fins and out over the silencer.

This system of cooling will ensure that the hot rear side of the engine will also be cooled adequately, preventing any distortion and subsequent loss of power. This is a very serious problem with many large volume silencer bolted directly onto the cylinder preventing this essential all round cooling. The silencer compartment must be shut off from the fuselage with 4 mm thick Balsa sheet. Light Balsa wood has excellent insulating properties as well as being surprisingly heat resistant. It is totally unnecessary to cover the Balsa with Aluminium foil or similar. The cooling air exit with the minimum size of 30 mm x 120 mm is placed immediately in front of the Balsa dividing wall in the floor. To increase the suction effect glue a small triangular strip on the front outside edge of the opening.

Stainless Steel Tuned Pipe for the ZG 38SC

This tuned pipe is precision engineered from stainless steel, and laser welded and highly polished. The geometry is exactly that of the Seyer tuned pipe but is indescribably better. Before Seyer ceased business we bought the complete set of tools and dies so we can exactly reproduce these pipes.

Tuned length from exhaust flange to start of reflex cone: 710 mm. Weight: 375 g.

Tufnol throttle arm d=3,9

This CNC milled throttle arm fits the throttle shaft from the ZG 20 to ZG 38. It is glued with Araldite 2011 (UHU PLUS Endfest 300) to end of the throttle shaft considerably simplifying the throttle hook up.

Throttle Arm #3879 EUR 1,15

Throttle Linkage, only for the older ZG 38 with the

Carb without Choke.

Comprises three ball joints, one bellcrank, angled bracket, screwed rod and screws. Makes for a compact and a play free coupling to the throttle arm from the rear. The bellcrank with the angled bracket is fixed onto the engines crankcase. With the ZG 38SC the carburettor is mounted so that a Bowden cable can be directly fixed to the throttle lever.

Throttle linkage ZG38 #3895 EUR 5,50
