OS ENGINES AIRCRAFT 2/STROKE ENGINES MAX-55AX (40K) W/E-3071, Product Code:15612

This is the O.S. Max .55 AX Aircraft Engine with Muffler. Advanced Bi-Metallic Liner process uses a double layer of plating material rather than one thick layer. This helps the metal bond to the cylinder and makes the plating more durable. Also, the plating process is more consistent, resulting in a more precise fit between piston and sleeve for better compression and longer life.

Features

  • Same mounting dimensions as the O.S. Max .46 AX
  • Power Box positionable muffler
  • Angular head design offers increased surface area for better cooling
  • 40J Carburetor with diagonally placed Needle Valve eliminating Remote Needle Valve placement

What are pre-orders?
Pre-orders are as the name suggests, placing an advanced pre-release order on an item. This means that the order you are placing is for the future release of a product that has yet to be released, or re-stocked.

How much are pre-orders?
Pre-order prices are defined at the time based off what we initially received from the manufacturer. This means that when we receive the product (to send to you), manufacturing costs, taxes, and even economic shifts in the country of the manufacturer, could affect the final price when we receive it in store. So, we suggest you use the price shown only as a point of reference, as it may not be derivative of the final price when it is received and ready to be sent to you.

How long do I have to wait for my pre-order?
The wait time depends on the release date of the pre-order product, and the time you placed your order. Pre-order release times also vary per product, per manufacturer, transportation and many other factors. If a release date is given from the manufacturer, please note that this is still subjective due to circumstances out of our control, and this isn’t indicative of our in-store stock date this could be a day or two after the release date.

Why am I being charged for my pre-order, even though the product isnt released yet?
This is pre-payment for an item's payment and delivery costs that isn’t released yet (pre-order) to ensure as soon as it arrives your order can be fulfilled and sent out to you a.s.a.p. Not all orders will be charged shipping depending on size, and total order amount (see our website for current shipping to find out more and our shipping policy for more information).
