Newer, lighter motors
« on: January 12, 2008, 05:46:42 PM »
Hi guys, I believe most of the newer type motors have more power plus much lighter than the old type motors. Isn't a lot of the stunt ship designed for the older style motors that weigh much more than the newer one's? Haven't we always worried about to much tail weigh? Most ship I have seen doesn't need tail weigh, I believe some ships have been named tail dragger. Just wondering how you could make tail lighter for lighter motor. Most builders I know use a lot of different methods to make tail light as possible. If they went to a lighter motor, they would end up putting weigh in the nose to balance plane. I guess what I'm asking is, what do you gain, for all the extra money, by using a lighter motor. Most engine we use, we don't use all the power it will develop. Just another dumb question, Gary

Gary,
What you say is of course true, if you would put in a smaller motor than the old historical motors, and then run them in a relatively higher rpm mode. So here you can have 25's replacing the 35's of yore (of course that old Fox35 was a light as a modern 25!).

What seems like is happening to me is that people are actually putting in much larger displacement motors than before, and then running them is a low rpm solid 4 stroke mode, with relatively large props. So even though those motors may be light compared to some of the RC engines of equivalent size, when all else is said and done, I am not sure that the nose weight due to engine choice has really gotten lighter.

Just my opinion of course!
