How to Decide on Components For an RC Aircraft - Gas Motor to Electric Conversion

This is vital simply because you will need to have to decide the electric motor centered on your styles capabilities, and what you want it to do.

Example: Hangar nine Arrow with a.forty size gas motor.

Would necessitate an electrical RC motor equivalent to a AXI 2826/twelve External Rotor Brushless. This motor would enable this product to complete common aerobatics with its semi-symmetrical wing.

Specs of the Hangar nine Arrow

You will will need these numbers to enable identify the motor, battery, and prop prerequisites.



 Wingspan: 63 in   Overall Length: 52.five in   Wing Spot: 710 sq in   Flying Bodyweight: 5.7 lb (as a radio controlled fuel plane)   Engine Size: converting a conventional.forty dimension RC gasoline motor to an RC electric motor.



Now you want to establish what sort of batteries you will need. This is primarily based mainly on your budget and time till land variable. In other phrases, how extensive do you want to fly for and still get overall performance.

The most evident decision is going to be a Lithium Polymer battery, this is the most superior battery technologies available for RC design airplanes. They are also the most highly-priced. Other older battery technologies are readily available, these as, lithium ion and nickel metal hydride. They can do the job, but at a weight charge and flying time consideration. So choose carefully.

In the Arrow Instance: We will use a 4200 mAh 11.1V Li-Poly Pack. This was determined primarily based on the flight functionality we ended up right after, some aerobatics, but generally secure simple likely flying. Absolutely nothing far too extreme.

As with any gasoline RC plane conversion to electric (or any electric radio managed airplane for that matter), you will have to take into account an ESC (electronic pace management). This hooks up to the motor, battery, and receiver. You will need to have to decide on one that can manage the essential range of battery packs, servos and have programmable characteristics. This will make lifestyle easier for you if you select a person that is characteristic prosperous. Of all the parts, this is one to expend a tiny much more on. You will be glad you did.

For this instance, we utilized a 40 Amp Brushless Controller with Program functions. There are tons of suppliers of ESC's so take the time to Analysis them.

Prop Variety is an essential consideration. You want to be aware that with an electrical conversion there is a chance that your product airplane will not have adequate clearance when utilizing an electrical motor prop. It may possibly require modifications to the landing gear (producing them for a longer time) so that the prop has clearance.

For the Arrow instance we employed an APC 13x10 propeller. Most electric motors now have a table that you can find on their internet site that will propose the propeller range to remain within just.

A single final consideration with RC gasoline planes transformed to electric. You often require to issue in cooling of the battery pack and esc. In simple fact lots of modelers, like myself, set the ESC on the exterior of the airplane, usually I mount it below the engine on the firewall. You also have to have to make air vents to neat the battery inside the design. rc planes
