We want to thank you for buying one of the strongest 50cc class engine available in RC gas engines, Please read the following instructions and you will have many hours of enjoyment with the product

Break-in should be done on the airframe not on a test stand and if small amounts of break-in are done while airframe is not flying do it in small limits, The engine can over heat if air is not moving over the cylinder. Run for a few minutes and then let it cool down.

For break-in use 32 to 1 oil mix with any good two cycle oil air cooled oil. You only have to run two gallon and then you can change over to synthetic at 50- to one, Not all synthetic oils are the same so follow the instruction on the oil that you use.

Example
If you are going to run syntactic oil we recommend using  Bel-Ray H1-R mixes at 50-1

For better life and cooler running we recommend using Pennzoil air cooled two cycle oil 40-45 to one ratio after break in
The best starting point for the carburetor setting is 1 ¾ on low and 2 1/8 out on high. It is best to run the engine a little on the rich side to start with.

When installing the engine make sure that your fire wall that the engine is to be mounted to is strong and secure.

Always use blue loctite on bolts when mounting

The engines comes with a muffler gasket but we recommend not using it, They will depress over time and cause the muffler to come lose. It is best just to use a good high temp sealant like Yama bond or silicone.  

The engines comes with prop bolts on engine and another longer set, Some props like Vess take a longer bolt, Just use the bolts that give you the most deep in threads, If you do need to replace the prop bolts with a different size make sure you use case hardened bolts or the power of the motor will shier them off.

The ignition is a standard 28 deg above top dead center timed ignition and should only be run with a 4.8 volt battery,  

Always check prop bolts after a couple flight to sure they are tight, Wood props will depress after a few runs and cause bolts to become lose. 

Starting props form 22-10 to 23-8 are a good choice, Vess 22-A or 23-A work well also.
Not all props are the same even if the same size and pitch, Some will put more load than other.

The best power range is from 6600 RPM to 7200 RPM
