About this item

Offered is a nice used O.S. MAX .46 LA R/C Engine. This engine has barely been broken in with having less than a gallon of fuel through it. It is a great reliable engine that is suitable for the new R/C pilot's trainer or for the seasoned pilot's sport plane. O.S. MAX reliability and simplicity is built in and quite powerful with its Schnuerle porting (see specs below). This engine has the "remote" needle valve to keep your fingers away from the prop while make adjustments. It comes in its original box with muffler, muffler bolts, glow plug and manufacturer's instructions. The VP Model Engine Diplay Case NOT included.

This is the more attractive "Blue Powdercoat" version. Street price for this engine new is about $68.00 plug tax. So, you can save yourself a few bucks here as well as the hassle of breaking in.

Item Number OE - EO1512 - Nice O.S. MAX .46 LA R/C Engine

This is a nice engine, but it is used and there are some items that should be noted. The engine is very clean, but there is some castor and exhaust residue present. The Phillip's muffler bolt heads are the victim of the wrong sized screwdriver. They work, but you may want to replace. The remote needle valve bracket was altered to accommodate fitting the engine into a tighter space than originally allowed. Also, there is a "crack" at one of the needle valve stay's (bracket's) mounting holes. It is still perfectly usable as can be seen in the above photo. The needle valve stay and muffler bolts are available online at Tower Hobbies for $2.79 and $1.89 respectively if you feel the need to replace with genuine O.S. parts. The prop washer and nut are not original and are silver colored rather than black. Lastly, there is a small piece out of one muffler fin (on the muffler's bottom side) as can be seen in the photo below. None of the preceding items mentioned affect performance in any way. They are mentioned so you have a better idea of the exact condition of this engine.
