You are correct. That was my question. Your reply that he changed engines did not answer the question. In fact, it wasn't even an attempt to answer the question.

Again, was there any noticeable change in speed by merely modifying the clamps? I'm curious, because the clamps are so large you can easily see them when the model is on final. Seems to me they would create a huge amount of drag when flying at close to 300 mph. So, again, for the forth time. Did the exposed clamps slow the model down. If so, by how much?

Sarcasm? No, not this time. Just asking a simple question and looking for an answer to that question.
