RCModelReviews | Overview: Nitro engines (the OS55AX) @RCModelReviews | Uploaded 6 years ago | Updated 23 hours ago
A lot of people have been asking about nitro engines for RC model planes so I figured I'd do an unboxing of the OS55AX engine and talk a little bit about the differences between nitro and electric.

If you have questions, or would like to follow a "nitro build" on this channel then please let me know and I'll be happy to accommodate.
