Frequently Asked Questions
- How do I know the correct elevator (pitch) and aileron (roll) trim tab size?
Your trim tab size will mainly depend on the speed of the airplane. The higher the average cruise speed the smaller the trim tabs need to be. The aileron and elevator will usually have different sizes of trim tabs. Recommendation: for experimental airplanes 2000 lbs. gross weight or less, choose your trim tab depending on the average cruise speed. The design calls for the trim tabs to have enough authority to fly the aircraft so long as the pilot can easily override them. The sizes that are available are:
Extra Small: 8” x 1.4”
Small: 11.8” x 1.4”
Medium: 11.8” x 2”
40-100 KIAS: Medium trim tab
90-160 KIAS: Small trim tab
160 KIAS or more: Small trim tab cut to 8” length.
Small: 11.8” x 1.4”
Medium: 11.8” x 2”
Large: 12.8” x 3”
40-100 KIAS: Large trim tab
90-160 KIAS: Medium trim tab
160 KIAS or more: Small trim tab
You can watch this video for more information in regards to the installation process.
- How do I know the correct servo type?
There are two servo systems available. Both systems can be adhered, riveted, or screwed onto the trim tab itself or anywhere on the flying surfaces.
Standard Servo: the standard servo is very light, it is encased in a very slim shell. They are splashproof and very suitable for fast airplanes.
Dimensions: 2 3/8” W x 3 ½” L x 15/32” H ( 60mm W x 89mm L x 11.9mm H)
Weight: 1.8oz (51 grams.)
Waterproof Servo ($45 extra per servo): our waterproof servos (IP-67) are not as slim and are also a little heavier than the standard servos. These are generally used in slower amphibians where servo weight is not an issue when balancing flying surfaces.
Dimensions: 2 3/8” W x 3 ½” L x 15/32” H ( 60mm W x 89mm L x 11.9mm H)
Weight: 3.0 oz (85 grams.)
- How do I know the correct trim tab installation type?
There are basically three ways that you can install the trim tab onto your flying surface. It can be adhered, riveted on a flat aluminum aileron or elevator, or rivet to a fabric airplane.
Adhering to your trim tab: A carbon fiber with a riveted plate as well as the double-sided tape will be supplied for this purpose. Just clean the surface, peel the backing, and adhere the trim tab to the trailing edge of the aileron/elevator.
Riveting to an aluminum aileron/elevator: A predrilled hinge and 3/32” rivets are provided for this purpose. Pop rivets are used to install the hinge onto the elevator or aileron.
Riveting to a tube for fabric airplanes: A fabric airplane will not usually have a flat surface to adhere or rivet the hinge. A predrilled curved hinge and 3/32” rivets are provided for this purpose. Pop rivets are used to install the hinge to the tube.
- How do I know the correct servo installation type?
The servo case with servo can be adhered, riveted, or screwed on any surface. We must know, however, if the servo is going to be installed on the trim tab itself or at a remote location on the aileron or elevator.
On trim tab: A standard pushrod is shipped.
Remote installation: A 12” long with a carbon fiber reinforcement is shipped. You will have to cut the pushrod to the correct size and do the Z bend.
- Does the iLevil AP have a warranty?
Yes, your unit is warranted against defects in materials and workmanship for a period of one (1) year from the date of original retail purchase.

Yes, you can use the Levil Aviation app simultaneously while using navigation tools such as Foreflight, iFlyGPS, WingX Pro, and many more. For a more in-depth explanation watch the video below.
- How much speed can the iLevil AP handle?
It all depends on how well the Aileron/elevator is balanced and the size of the trim used. The standard trim tab kit provided on the website is ideal for airplanes cruising at speeds within 100 and 180 kts. For aircraft outside these cruising speeds, please email Aircraft Automation for custom trim tabs (firstname.lastname@example.org)
- Can I mount the iLevil AP on a certified aircraft?
No, the iLevil AP is only intended for experimental and light-sport aircraft. If you fly a certified aircraft, we recommend our FAA NORSEE Approved iLevil 3 AW or the BOM.
- Can I get weather information?
The iLevil AP has real-time weather and traffic with an optimal high-quality ADS-B receiver. It also maximizes reception while maintaining low power consumption. There is no need for remote antennas. It captures the weather and traffic information even where other devices won't reach it. Satellite weather is not available.
- Can I store my flight data?
All flights are stored inside an SD card which you can access anytime to replay, review, analyze, and share. Recording features are also useful for flight schools. It features 3 serial ports that can be used for data transfer between tablets and other avionics in the cockpit. The new Data Recording features allow you to insert an SD card and record all of your flight data such as position, airspeed, altitude, etc. and display the information on various platforms.
- What's the battery life?
The unit runs as long as it's plugged into the aircraft. It also has a backup battery that lasts 5.5 hours and charges via USB.
- What's the iLevil AP weight and dimension?
The iLevil AP sensor box weighs 11oz (311g) with dimensions of 3.2" x5" x1.1" (8x12x3 cm). Each individual Trim kit (including servo) weighs 5.3oz (150g). The dimensions of 1 trim tab is 12 "long, the moving part is 2" wide, and the servo placement is 4 "wide. The thickness of the carbon fiber blade is 0.04".
- Is it easy to install?

- Can I connect it to other navigation devices?
Yes, you can connect the iLevil AP to other navigation devices like Garmin GTN-650 or 750 and others alike using RS 232 aviation data or NMEA $GPRMB autopilot string.
- Is it easy to override?
Yes, you can easily override the iLevil AP and the trim tabs with your joystick since there aren’t mechanical links with your flight controls. Control links and cables are always free to move. You don’t need to use additional friction since there are no conventional servos installed. No external Autotrim is necessary.
- What happens if I want to disconnect the autopilot?
Since the system works with trim tabs, auto-trim is built into the iLevil AP. No additional installation is required. The airplane will always be in trim following autopilot disconnection.
- What happens when the auto-pilot is off?
When the autopilot is off, the trim tabs are still active. The system will correct for excessive or unwanted pilot inputs beyond a roll or pitch limit.

We're certain that you'll love the iLevil AP! or we're happy to offer a 100% money-back guarantee within 30 days after you receive your unit.
I have just finished installing the AP on my Mk25 Spitfire and done the calibration to set all the parameters. What a fantastic innovation! It flys really well and is responsive without overshooting heading or altitude. Balancing and testing for flutter was not as hard as I thought it might be and I had no issues.
Affordable and quite easy to install. I’m really pleased with it. Will be great for long cross country flights. I have yet to work out how to use the nav follow function but so impressed I have purchased a second AP for my Zodiac 601 which has 9 hours endurance so AP would be great to relieve long flight fatigue.
I am still in the install process of this AP. So far I like what I have seen and am looking forward to testing this system out. It should be fully installed in the next couple of days and a comprehensive evaluation will be completed. I am happy to post my evaluation on Facebook or to Levil for them to post on their website.
