Control the electronic ignition of your gas powered aircraft via your transmitter.

The ignition switch 3 has been developed for turning on and off electronic ignitions in gasoline engines by remote control. It is suitable for all gasoline engines with battery-powered ignition systems.

The ignition switch 3 is superior in all respects to using a mechanical ignition switch and has the following benefits:

  • No wear
  • Elegant shutdown of the engine using the transmitter
  • Improves safety by utilizing the remote control's fail-safe function
  • In case of a fault, the motor can be switched off safely
  • Can be used to control systems other than ignitions; eg.lighting systems

The ignition switch 3 is microprocessor controlled and utilizes an optocoupler that separates the receiver & ignition circuits. 

The ignition switch 3 can be operated in parallel to the throttle servo if an addition receiver channel is not available. In this configuration, the ignition switch 3 is connected directly to a servo plug, which in turn is connected to the throttle servo. By adjusting the switching point and switching direction, it is now possible to set the ignition to switch off when the throttle trim is reset during idling or by switching the throttle channel with an additional mix.

The circuit has several fail-safe features that ensure that the ignition is switched off safely during emergencies. For example, the ignition can be set to switch off if the transmitter signal has not been received for three seconds. 

When switched off, the ignition switch 3 consumes no power from the ignition battery. The plug connection to the ignition battery therefore only has to be disconnected for charging. 

The ignition battery may also remain connected to the ignition switch 3 when charging, if it is charged via a separate charge cable.

The Ignition Switch 3 comes with:

  • Switching module and cables
  • An XT30 connector which connects the ignition to the module
  • An LED which can be mounted on the aircraft that provides visual confirmation that the ignition is on or off

A replacement LED indicator is available separately if needed, see the related products link below.

Input Voltage 3~9V
Min~Max Switching Voltage 3~15V
Maximum Switching Current 5 A

Very effective dermaplaning
I was really very impressed with these dermaplane razors. At first, I thought they were a little pricier than what I am used to, but after using them, I feel like they way more effective than others I have used. I thought they did a perfect job of removing all the post-menopause peach fuzzy I deal with. They left my skin smooth and did not leave any type of irritation on my skin. They come in two lengths, but I thought they were both equally easy to use. The handles are a nice, ergonomic shape that is easy to grasp. The blades stayed sharper longer than others. I will be ordering more of these and recommend them.

I like the design of these dermaplane razors
I have been using a different brand that folds in half for easy travel but the drawback was a small and unreliable handle. Not so for these razors – the straight handle allows for a more controlled and steady shave, I don’t have to worry about my razor folding up mid stroke. The blades themselves are a decent length and come in two different sizes. I have been using the larger ones for dermaplaning and touch ups whereas the smaller blades work great for shaping up eyebrows. These are not the highest quality razors, I mean not terrible but I did have one of the razor parts pop off of the handle unintentionally. I feel like $13.99 is on the higher end for 12 razors, I have seen similar blades for cheaper and larger quantity (although they didn’t have the two different sizes).

12 pack derma planing razors
I am a huge fan of derma planing and was quite intrigued by this set of razors. I was curious how they'd stack up to my tried and true disposable razors hat I've been using for years. First, they look and feel pretty nice - definitely nicer than my current ones. I do wish the handles were a lil more grippy because they get slippery very easily if they get wet or if you accidentally get oil/lotion on them. There isn't any indication of how many times you can use each razor or if they're only single use. There are two different sized razors included, but I'm not sure what the smaller ones are for - I wish they'd include some instructions! Currently priced at $13.89 for 12 razors, I find the price to be too high for what you receive. They are nice razors, yes, but they are not premium quality.

Effective dermaplaning wands
These razors work really well for removing my peach fuzz. I have a fuzzy chin and hair on my knuckles that’s hard to get off with a larger razor. These come in two sizes for precision dermaplaning. I apply some jojoba oil to my skin before dermaplaning and there is no irritation. I love the frosty translucent handles, they look clean and professional. There are twelve to a pack and they come in a little box to keep them all together. These are a great value for the quality.

Fast & Easy
These work really good. I have been waxing for over 20 years and I just wanted to try something new. This set comes with two different sizes. I used the large blade for my chin and lip. And the smaller blade for my eyebrows. The handle is sturdy and not flimsy. Comes with a case. I already stuck one of each in my travel bag!
