1, How to identify real RCGF Stinger engines and fake RCGF engines in the market ?
Recently we received questions from consumers that asking us how to identify the fake RCGF engines and real RCGF Stinger engines ,and where can they purchase the real RCGF Stinger engines . We think it’s important for us to let consumers know about all these information .

In order to get the real RCGF Stinger engines and also reliable warranty service , please purchase the engines from our RCGF Stinger authorized distributors .  You can find our detail distributor list in the distributor page . 

Consumers can verify the RCGF Stinger engines with the unique serial no in our website or send email to us . We will be glad to verify for you .  (The serial no are lasered in each of RCGF Stinger engine )

2,  What's the difference between RCGF Stinger Engines and old RCGF engines ?

Most of our customers knew that we've updated into Stinger Engines . Because of the aging mold sets for our old RCGF engines, it became very hard to produce a good quality part from the old molds .  We are now in complete control over the entire build for the Stinger Engines . This means from the molded part production to the completed engine . We now have total quality control in order to produce the best product for our customers . We are using a more robust metallurgy for the case parts and the stronger crank system with high quality bearings to provide more power per cc , plus an all-around better-looking engine .

But the previous old RCGF engines which sold by us or our authorized distributors before are all quality controlled by us . They're with stable quality. Our factory will still offer service for them .

3, Where can I get after service besides from RCGF authorized distributors ? 
 If there are some problems which distributor can't handle it , or there is no distributor near you , please don't worry. You can get after service from our service centers or our factory .  Please do not forget to offer the unique serial no of that engine to us, when you need the service from us.

4, Which Oil should I use?
Some oils available in suitable for running in include Castrol 2T, Mobil 2T, Penzoil Air Cooled 2 Stroke. 
Synthetic oils suitable for use after run-in include Castrol TTS, Belray HR1, Red-Line 2 Stroke Racing Oil.There are many types available that are suitable, always use a good quality brand name oil, both for run in and normal running.Motorcycle shops are a good source for quality oils. Remember your engine will spend most of time somewhere between 2000 - 5000rpm so castor based motorcycle/go cart racing oils designed for very high rpm should not be used.Never mix different brands of oils together.
5, Starting the engine should be relatively simple. 
1). Ignition OFF  2. Choke ON  3. Throttle OPEN wide 
4). Flip the prop until you see fuel coming into the carb OR you hear it gurgling in the carb 
5). Flip several more times. 6. Close throttle  7. Open throttle slightly (less than 1/4) 
8). Choke OFF  9. Ignition On  10. Flip prop to start. 11. It is assumed your plane is well secured!!
