Magnificent rc helicopters performance

The crankshaft of rc helicopters is carefully machined, and the counterweight keeps a record fine on one hand limits the volume of pre-compression chamber and the other protects a little crankshaft main bearings. 

In case you did not know, each rc helicopters consists of varied complex parts. To ensure top performance, you must get to know top tips and hints for optimal care and maintenance. For instance, the propeller nuts are made so that the interaction with the OS 140 is total, must be borne in mind that the cone competition is supported by the propeller nut.

The fuel supply is ensured by a membrane pump, non-detachable non-adjustable, and a carburetor idle slot driven cam. The remote needle can be mounted anywhere in the model and not just at the top of the crankcase. The 3M Mintor a motor 170 is intended to replace the well-known Japanese smoothly, almost all external parts are interchangeable, and the only problem may be linked to a strange noise- Expect to hear the propeller spinning with this new engine.

Consider a function test, after rc helicopters adjustment by hand 3M170, this will start of course with a "chicken leg" but it is more reasonable to use an electric starter on an aluminum cone. The manufacturer recommends a fuel with at least 15% nitro and 15% of synthetic oil, we have used 20 and 20 fuel, oil and nitro over time not to miss. The APC system reached a 17/12N is 8,200 rpm This helix is the smallest that can be mounted as it is terrifying the feeling of power you feel with it, the engine handles well a Dynatrust r.pm 18/10 to 7,200 or more as the engine to be mounted in the Trazator we have not dared to tune it more. The latter helix I once mounted an engine 35 cc Webra Bully giving a similar performance.

For use in competition, you must think of a 16/14 or 17/12 APC as desired speed more or less, or even a three-blade or equivalent our landing gear if we fall short. In summary, we forward until we get to know the most powerful rc helicopters engine for F3A aerobatics with which you can get to this day is not a sport but motor racing and therefore requires some expertise to operate properly, do not think in dock in a large model, its use is unique and exclusive precision aerobatics. This version 170 is powered variant of the 140, most of the current acrobatic settle for the latter.

Consider using 17/12 rc helicopters and fuel with 20% oil and 10% nitro methane resulting in a very safe and powerful operation.
