Default RE: question-more weight or engine downthrust

I guess once again I'm going to have to be the one to do it. Something completely avoided so far is knowing a little bit about what you intend to do before jumping in. Take the time to do some research and learning before divinginto the pond. It just might be too shallow to go head first.

Most of the planes we fly will have an effective CG for most people between 25% and 33% of MAC. 25% is very stable. 33% is less stable. Some planes can go as far back as 37% of MAC in the right hands. Note I said in the right hands. Unless you're flying a delta winged craft those numbers work 99% of the time.

Next is to always start out with a clean radio. By clean I mean it hasn't been used to set up another plane on that memory channel, or if it has that memory channel was cleared out and in factory default stage.

Next is to learn how to trim out a plane, and what actions are intended for what response. Several websites devote some attention to this activity, and many articles have been written in magazines to explain this to people.

Just because one wants to do something does not absolve them of investing the time and effort in learning about the activity before getting started. There might even be a requirement to invest in a few tools that will let you accomplish the task. Because some of this stuff may cost more than you want to spend or afford doesn't make it someone elses responsibility to fix for you. Nobody is entitled to fly anything. They earn the right and ability through personal effort and experience. You don't start at the top.
