The original poster, blacktails, didn't ask anything pertaining to the price of equipment or anything of a "this brand" vs. "that brand" nature. Since he happily shelled out the cash for a Pulse XT 40 ARF and a Saito .62 4-stroke and then decided he should get another plane together to fly first, I don't think saving $20 or $40 is his top concern. Answering questions that haven't been asked will be of little help.

He just wants a good .40 or .60 size trainer that will fit in his truck. He'd prefer a bolt-on wing rather than a rubber-band-and-dowels setup, but he'll go with rubber bands and dowels if the "experts" recommend it. He already has a K&B .40 2-stroke and a Saito .62 4-stroke and he wants to know which, if either, he should use on his trainer.

If you think the original poster should buy a particular engine, or if you have any other advice for setting up a good trainer, simply explain why.
