How to Install a Manual Transmission on a Black Horse Chipmunk Model Plane
If you are looking for a challenge and want to upgrade your Black Horse Chipmunk model plane with a manual transmission, this article will guide you through the steps. A manual transmission allows you to control the engine speed and propeller pitch more precisely, giving you more performance and realism. However, it also requires more skill and attention to operate safely and efficiently.
Before you start, make sure you have the following items:
A Black Horse Chipmunk model plane with a 55-61 cu.in-2 stroke or 91 cu.in-4 stroke engine. You can find the instruction manual book for this model here.
A manual transmission kit compatible with your engine. You can find some examples here.
A propeller suitable for your engine and transmission. You can find some examples here.
A servo and a pushrod to control the transmission lever. You can use one of the spare servos that came with your model.
A radio transmitter and receiver with at least 6 channels. You can use the same radio system that you use for your model.
A battery pack and a switch harness to power the receiver and servos.
Some tools such as a screwdriver, pliers, wrenches, drill, etc.
Once you have everything ready, follow these steps:
Remove the propeller, spinner, and engine from your model plane. You may need to disconnect some wires and fuel lines.
Install the manual transmission on your engine according to the instructions that came with the kit. Make sure it is securely attached and aligned.
Install the propeller on the transmission shaft according to the instructions that came with the kit. Make sure it is securely attached and balanced.
Install the engine and transmission assembly back on your model plane. You may need to adjust some wires and fuel lines.
Install the servo and pushrod that will control the transmission lever. You can mount the servo inside the fuselage or on the firewall. Make sure the pushrod is long enough to reach the lever and has enough clearance from other parts. Connect the servo to an unused channel on your receiver.
Adjust the servo travel and endpoints so that it can move the lever from low to high gear smoothly and without binding. You may need to use a servo tester or your transmitter to do this.
Install the battery pack and switch harness inside the fuselage. Connect them to the receiver and secure them with velcro or tape.
Check that everything is working properly before flying. Test the engine, propeller, transmission, servos, and radio system on the ground. Make sure there are no leaks, loose parts, or interference.
Congratulations! You have successfully installed a manual transmission on your Black Horse Chipmunk model plane. Now you can enjoy flying it with more realism and performance. However, remember that operating a manual transmission requires more skill and attention than an automatic one. You will need to shift gears at the right time depending on your speed, altitude, and maneuver. You will also need to monitor your engine temperature and avoid over-revving or stalling it. If you are not familiar with manual transmissions, we recommend that you practice on a simulator or with an experienced instructor before flying your model plane. ec8f644aee
