Hello there,

I have a Webra 1.45 in my Hydeout and I love it. It has tons of power and is very reliable. I was a little skeptical at first (I don't know why) but I am very glad that I picked up this engine. Not only is it cheaper than the OS, but it is a little better engine in my opinion. The Webra is a little bit bigger, but it has more power, weighs less and costs less. They are both very high quality engines, but if you want more bang for your buck, I would go with the Webra.

Here are the specifications that I got off of the Tower Hobbies website and the Piedmont Models website. They are for the OS 1.40 RX (NOT the injected version) and the Webra 1.45 Aero X respectively. I would not reccomend the injected version of the OS 1.40 because the injectors go bad quite frequently, and I have seen this first hand many times. This is just my opinion, however, and I hope that this helps.
