CONCEPT WOHM FLAT TWIN GLOW ENGINE
This is the first prototype WOHM flat twin glow engine that was built. Based on the 3.5cc TBR glow engine it is 7cc displacement with the same bore and stroke of the single cylinder engine. Intake is via reed valve but we will also be utilizing front/rear rotary valve intake options as well.

WOHM LONG STROKE RADIAL REPLICA PROTOTYPE
This is the prototype engine of the replica WOHM number 1 radial. The number 1 radial was the first radial engine that Wolfgang Built and he only built 2 engines to this design, the number 2 engine which was finished with red anodizing and is in the company museum.

Proof of Concept new design WOHM 10cc Glow Radial engine
This is the first concept redesign of Wolfgang's 10cc 3 cylinder radial engine. The object was to reduce the over-all size of the engine making it smaller and more compact, yet retaining the original displacement of 10cc
Experimental CLAMO V4 Glow engine
This engine was built as part of the CLAMO V series of engines when developing the CLAMO Shadow 10cc V4 engine. We will be expanding on this theme in the future.
Experimental CLAMO Spectre
This engine was built as part of the development of the CLAMO Spectre V-twin engine. Built as a proof of concept and design layout check. The engine was built using 2 original Taifun Zyklon cylinder and liner assemblies fitted to factory made case/crankshaft assemblies, all machined from solid. Engine performs well. Total displacement is 5cc

Experimental WOHM long stroke 3.5cc Glow engine
This engine was built as an experimental glow version of the WOHM 3.5cc longstroke diesel engine
Proof of Concept New Design 15cc WOHM GLow Radial Engine
This engine was built to prove the build concept of a much reduced overall size design of Wolfgang's original 15cc diesel radial engine with the added conversion to glow ignition. The engine went together relatively easily and runs extremely well. Bore 18.80mm Stroke 18.00mm
WOHM 5cc drum valve Diesel engine devolpment
This engine was built to experiment with a drum valve inlet system. The purpose is to develop a higher performing C/L engine. Bore 18.80mm Stroke 18mm
MORE INFO
proof of concept Wohm 15cc radial diesel engine
This engine was built to prove the new design of the original engine built by Wolfgang. The objective was to create an engine that was much smaller and lighter than the original engine and producing more usable power.

proof of concept engine of the clamo wraith
This is the proof of concept engine built to prove the work-ability of the supercharger intake concept.
experimental wohm 5cc diesel tbr c/l engine
This engine was built as a prototype engine for the future production of 5cc diesel and glow control line stunt engines. The case is machined from solid and all machined on manual machines. Bore=18.80 mm Stroke= 18.00 mm
WOHM 3.5cc CONCEPT GLOW ENGINE SERIES
This is the experimental WOHM 3.5cc glow engine development series for control line and R/C flying. We are currently building the last prototype engine prior to full production once this latest development engine has been fully tested.
MORE INFO
experimental wohm 3.5cc diesel
This is an experimental 3.5cc TBR diesel engine designed primarily for control line flying, although R/C carbs will be available for all production engines.
prototype clamo phantom flat 4 glow engine
This is the prototype CLAMO Phantom flat 4 glow engine. Engine uses center rotary valve induction and is built using 4 Webra Mach1 glow engine piston liner assemblies although the pistons were made and fitted in the factory. The case and shaft, rods, heads etc are all factory made using the same 1 piece shaft with split con-rod set-up. total displacement is 10cc
experimental flat four glow engine
This engine was built as an exercise in designing a flat four twin reed valve intake engine. The engine uses Webra record piston liner assemblies on a factory made case/crank assembly. Shaft is one piece with split con-rods as per full size practice.
