Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

The seller knew I was after one and very kindly informed me when they came back into stock so now have a Flywing Bell 206. Fantastic bit of kit. Well worth the wait.

Frequently Asked Questions
This is a .21 nitro engine (3.49cc displacement) designed for 1/8-scale RC buggies. It falls within the 300-400cc equivalent class and is a standard size for competitive off-road buggy racing.
The engine itself does not include an exhaust pipe. Nova recommends the Nova 2182 Off-Road pipe with either a 50mm or 55mm manifold depending on your preference, which you'll need to purchase separately.
The EVO specification features a DLC-coated crankshaft, steel ball bearing, and a 3-port cylinder with antifriction HCP coating. These refinements were developed through extensive testing and team driver feedback to improve performance, efficiency, and engine longevity.
Nitro engines require tuning, maintenance, and fuel mixing knowledge; this is not a beginner-friendly product. The B3R EVO is an advanced engine designed for experienced RC nitro enthusiasts and competitive drivers.
The product information does not specify fuel or oil requirements. Consult the engine manual or Nova's technical documentation for correct fuel type, oil ratio, and tuning specifications for this model.
