.12/.15 Car Engine Reviews
Kyosho use this pullstart engine mostly in their off-road cars such as the Sandmaster MkII, Stadium Truck and the Nitro Tracker. It is twin ballraced, side exhaust, and features a single needle carb to make setup easier for begineers, and performs well.
The GX12 pullstart engine is now being used in the majority of Kyosho's range. It is twin ballraced, side exhaust, features a low cylinder head which is excellent for sports style body shells, and has a single needle carb. The power output is also slightly greater than the GT-12S-CR.
The GX15 is almost identical in construction to the GX12, and as a result you get even more horse power crammed into the same size. It retains the same features, twin ballraced, side exhaust, and has a single needle carb. As the power output is greater than the GX12, the GX15 has a larger cylinder head..
This twin ballraced powerhouse is definitely one of Kyosho's finest engines. It is currently being sold with the more upmarket MkII Spider Series. It is without a doubt great value for money. Performance is comparable to some of the OS engines. Its is very easy to setup, again featuring a single needle carb, goes like a train, and is side exhaust.
Kyosho have improved on the GS-11R, an already brilliant engine by sqeezing more capacity and power into the same size. Again featuring twin ballraces, and side exhaust, but this time the carb is twin needle to enable you to get the crispest acceleration possible. It is currently being sold with the very competitive V-One S chassis.
Kyosho have taken another step towards making modelling easy with this electric start version of the powerful GS15R. It is idenitcal to the immediately above picture of a GS15R except the pull start has been replaced by a geared electric start unit. Due to its extra size this engine will generally only fit cars designed to accept it. The clutch assembly shown in the picture is not supplied with the engine.
This engine is smaller than the average car engine in capacity, but provides a decent amount of power at a competitive price. The OS Max 10FP-BX is sold with a pull start for ease of use and is a cheap way to own a superb brand name which guarantees quality and performance. Features a plane bearing crank shaft, side exhaust, and a single needle carb. Max power is .27ps @ 17,000 rpm. RPM range is 3,000-18,000

The LD-X is the first engine designed purposefully for cars (as opposed to buggies) and comes complete with pull start. The lay down design means a lower centre of gravity and the extensive finning provides exceptional cooling in limited airflow conditions. It even looks like a real car engine!. Features twin ballraces, and a twin needle carb. Max power output is 0.56ps @ 28,000 rpm. RPM range is 3,000-33,000.
The OS15CV-X is probably OS' most popular engine. Physically similar to the 12CV but it provides a 21% increase in power without the need to modify the car in any way. Outstanding build quality and breathtaking performance. Features twin ballraces, side exhaust, and a twin needle carb.Max power is 0.68ps @ 29,000 rpm. RPM range is 3,000-30,000.
As above but also featuring a pull start.

RPM range is 3,000-33,000.
