I like to build model airplanes, especially free flight as I think the quality of your building more directly is apparent in the flight characteristics of completed model. Small things matter such as using the correct wood density and grain type in the wood. The slightest warp can make be a major difference in flight characteristics. The adjustment process for a new plane can be interesting and frustrating but when you a build a model that takes little adjustment from the start that is a major thrill also.

I find it challenging. There are so many different types of models with unique challenges; part of it is how the model is powered. This year I worked with rubber power, electric, gliders towed up on hi-start and by human running, Co2 engine, and a small glow engine. For dethermalizers I worked with several types including fuse, electronic servo, electronic band burner, mechanical, and viscous. Deployment of the DT I used popup stab, popoff wing, and popup front of wing.

A Few Things I Learned this Year in Free Flight
* I learned this year that CG (center of gravity) on the plans is where it needs to be at least for a beginner and if the model does not fly correctly at that location, change the incidence do not keep moving the CG.
* I am learning how critical getting the correct trim settings in high speed phases of flight are and how necessary it is to slowly increase the motor run time. New issues can be seen further into the run that were not seen in the beginning of the flight.
* I am learning that flying surfaces cannot be moving around, rubber bands must hold tight, wing and stab need to be keyed so there is no shifting in flight. The structure needs to be stiff as well and weaknesses will often not show by visual inspection of the plane. When your plane hits the ground often it does damage that you do not see but twisting the model gently it might show up.
PS. Thank you for reading my blog posts, I am just amazed that views recently went over the quarter million mark.
