Another Tip of the Week from ATTF and HPP!
Remember, submit your tip of the week email to contact@allthingsthatfly.com to win a FREE 30 day FlightPass membership from Higher Plane Productions!!
This weeks winner is Hance In Idaho, here is his submission!!
I was in the middle of building my Yak55 and found out I had no pushrod material at all. It’s a 60 mile drive to the nearest hobby shop to get some so that wasn't an option. I was driving down the road the next day and seen a survey flag on the side of the road DING. I stopped by the local hardware store a bought some to experiment with. They fit 2mm dubro quick connectors perfectly. The steel they are made out of is kind of springy so if you slam a model into the ground odds are the pushrods will springs back straight. So no more bent pushrods. Best of all they are dirt cheap. Flags at lowes Its 8 bucks for a hundred 21 inch flags or 4 bucks for 25 fifteen inch long ones.

CG or Center of Gravity is the location on a model where it should balance. When dealing with a kit, ARF or model from a manufacture, they will typically provide the location for CG in the instructions. You will find that the CG suggested by the manufacture can make the model a bit nose heavy and for good reason. A model that is nose heavy will still fly fairly stable, reducing the chances of a poor handling. A tail heavy model will be very unstable and unresponsive to control inputs. Typically the measurement provided will be about 1/4 to 1/3 of the wing cord (depth from leading edge to trailing edge).
Depending on the model you may want it to be a bit nose heavy or more neutral. 3D and sailplane pilots will prefer a more neutral CG, and pilots flying fast sport models will likely want a touch of nose weight. The best way I have found to determine if CG is set properly is in the air. Yes you want to use the manufactures suggested CG point prior to flying the model, but once you have done that you can fine tune it a bit by doing a simple dive test. This is how I do it.
1. Get the plane ready for flight (typical preflight checks to include checking the CG)
2. Launch or take off and get the model to a comfortable altitude so you can get the model trimmed out.
3. Once trimmed to where the model will fly straight with no...Continue Reading

This week we follow up the control horn mounting tip with how the location of the pushrod controls deflection of the control surface. Really the most important thing to know in this tip is using the hole in the servo arm furthest from the servo and closest to the control surface will provide the greatest amount of deflection. Moving the pushrod closer to the servo will decrease the throw as will moving the pushrod further from the control surface.
This image shows a setup for Maximum deflection. Notice the longest part of the servo arm is used. On this setup there is no adjustment at the control surface side.

Going to gear this one towards foam models since that is what I am most familiar with, but please add your input for control horn installation regardless of model material or style. The most important aspects of installing a control horns are the alignment and the strength of the install. Having a control horn pull away during flight is going to have nasty results. To get the throw of the control surface to move properly and equally in each direction requires proper alignment.
To properly align a control horn you want it to be installed so that the holes in the horn are directly over the hinge line. I searched google and this is the first image I found.
Notice that the holes in the control horn are always in a straight line from top to bottom. This allows you to install the pushrod into any hole and maintain alignment over the hinge line.
