Building the Senior Telemaster ARF
Step 1: Landing Gear
Our team made changes with the strap material. We were concerned about the original strap material because during installation stress fractures were observed, which is illustrated on Figure 1. So, we substituted the plastic straps with the Gripper Pads found in Menards. The Gripper Pads, shown on Figure 2, material is more flexible, variable in size and easy to manipulate. Also, due to concerns of its strength, we increased the number of straps from 4 to 6 as shown on Figure 3.

unchanged recommendations:
- 2.60mm Aluminum screw replaced with Metal Material screw
Step 2: Installing the Glow Plug Engine
We decided to use the SuperTigre G90 engine considering the heavy payload of camera system, communication system, and sensors, over the SuperTigre G60.
There were various concerns that were brought up in the process of installing the glow plug engine on the plane. According to the instruction manual of the engine, it requires us to keep the Fuel Pick-up line no lower than 3/8" from the high speed needle. This creates various issues in installing the engine. After searching the web and asking experts in building RC planes, our team concluded that the muffler's pressure fitting into the vent of the fuel tank would be enough pressure to overcome any fluid-dynamic discrepancies for a smooth supply of fuel to the engine. So, after drilling a set of four holes in thinking to mount it up-side down as shown on Figure 4, we finally came to install the engine on as shown on Figure 5. Both #8 lock and flat washers were used on the #8-32 stove bolt that was cut into size.
