Just a few of the engines on which we have installed on our EVEs

Cross section:
firewall mounted 20-45cc EVE assembly
A 6mm ply pad is glued to the 6mm ply firewall at the location of each EVE to increase the length of bushing around the bolt. This pad can be placed on the front or rear face of the firewall depending on the need to move the engine forwards or backwards to align the prop driver face with the front of the cowl.

Cross section:
spacer mounted 20-45cc EVE assembly
A 6mm ply pad is glued to the 6mm ply firewall at the location of each EVE to increase the length of bushing around the bolt. This pad can be placed on the front or rear face of the firewall depending on the need to move the engine forwards or backwards to align the prop driver face with the front of the cowl. The M5 bolt is screwed directly into the stand off spacer and secured with a thread lock compound.

.40-.60 cu in - 4 small red bushings with M4 bolts - £7.50
Designed for mounting .40 cu in 2 strokes to .60 cu in 4 strokes. These EVEs are a scaled down application of the assembly detailed above, but do not have the internal spacer sleeve - this allows the necessary degree of bushing compression adjustment to fit any 2 or 4 stroke engine from .40 to .60 cu in, as well as facilitating thrust offset variation by tightening individual bolts

.60-.91 cu in - 4 small blue bushings with M4 bolts - £7.50
Originally developed by a requirement to mount an OS91FS, these EVEs are a scaled down application of the assembly detailed above, but do not have the internal spacer sleeve - this allows the necessary degree of bushing compression adjustment to fit any 2 or 4 stroke engine from .60 to .91 cu in, as well as facilitating thrust offset variation by tightening individual bolts

20-45cc - 4 large red bushings with M5 bolts - £11.00
These EVEs are designed for any type of engine in the 20-45cc range. They feature a stainless steel spacer sleeve that enables the engine mount to be solidly clamped between the M5 bolt and nyloc nut to prevent fretting. This is the only system that works with Laser engines - isolating the engine from the airframe, but securing it from torsional movement to prevent carb intake oscillation causes fuel/mixture supply problems. Suitable for radial/back plate or stand off mounted 2/4 stroke glow and 2/4 stroke petrol engines.

50-55cc - 4 large blue bushings with M5 bolts - £11.00
These EVEs are specifically designed for mounting 50-55cc 2 or 4 stroke engines. They use include a stainless steel spacer sleeve, M5 hardware and have a harder polyurethane bushing material than the 20-45cc EVEs. Suitable for radial/back plate or stand off mounted 2/4 stroke glow and 2/4 stroke petrol engines.

60-90cc - 4 large blue bushings with M6 bolts - £15.00
These EVEs are suitable for mounting 60-90cc 2 or 4 stroke engines. Instead of a spacer sleeve, they have an additional plain nut which, together with the normal nyloc nut, solidly clamps the engine mount to prevent fretting of the engine mounting holes. This also enables bushing compression to be adjusted to match the size of engine to be mounted, as well as facilitating thrust offset adjustment by tightening individual bolts. They have M6 hardware and have been successfully used to mount engines as large as 120cc.

Beam Mount System
1.20 - 1.50 cu in 4 Stroke engines - £16.00
The Apache Aviation 1.20 - 1.50 cu in 4 stroke Beam Mount System has been developed in response to many requests for an complete anti-vibration system suitable for beam mounted engines. Combining our 20-45cc Laser Engines-approved Engine Vibration Eliminators with a substantial Glass Filled Nylon ‘T’ Mount has produced the perfect solution. EVEs isolate the airframe fatiguing vibration yet firmly locate the engine on the firewall, preventing engine movement relative to the thrust line. The EVE through bolt is locked solidly onto the engine mount to eliminate fretting. Although originally designed for 4 stroke engines, the Beam Mount System is equally suitable for use on 2 strokes.
