I think LA40s are discontinued, both RC and CL. Often they can be had cheap New in the Box (whatever that means in actuality) at swaps, ebay and RC forums. LA 40/46, FP40/35, weigh 8.2 ounces. Enya 35 V (baffle piston engine) 7.9. OS 35s 6.9, Fox 35 6.5. All weighing just done on my postal scale. Engines with prop nuts, no props or mufflers. Considering the nose moment vs tail moment of the Oriental and most control line planes, it takes about half the weight in the tail to offset a heavier weight in the nose. A 2 ounce heavier engine can be offset by one ounce in the tail. Or in the case of an LA46 vs a Fox 35, a difference of 1.7 ounces in the nose can be offset by .85ounces in the tail. Overall weight penalty about 2.5 ounces. Perhaps a significant weight difference. Perhaps not. The difference in power between the two engines tho is quite significant. FP40/LA40s put out more power, turning significantly larger props at higher speed. LA46s way more power on large props and so on. I checked out Stunt News to see what competitors choose for Orientals, Noblers, and the like. At Brodak there were a large number of Brodak 40s. Engines weighing in about the same as a Fox35. These engines are of modern design and are potentially more powerful than a Fox. Lots of LAs, FPs, and a few Aerotigres. 3 (I think) Fox 35 powered Noblers or Orientals. At the NATS, I couldn't find a listing for engines used in Classic.
