IMO I will add to your post, and say that I personally avoid anything made by megatech based on past experience. I have had a couple of thier Electric Planes and Helis, and the Planes had cheap servos in them the size and weight of a volkswagon. Not to mention they flew like bricks. The Nitro Trainer ARFs they have are probally OK, but way overpriced I think. Since this is a thread devoted to Engines, I will not ramble anymore. Its just that I have not had many pleasurable experiences with anything Megatech that I have ever owned.
