After the start button is released, why does the starter appear to briefly remain engaged?
This is normal for a permanent-magnet starter. Although power is removed by releasing the key/start button, a permanent-magnet motor will actually provide power to itself as it winds down and will keep the starter drive engaged for about a half-second until it loses sufficient RPM to fully disengage.

All other anti-seize I have used are thick. How can this work when it is so thin?
The D A M high temperature anti-seize formula is based on inert high temperature dry lubricants suspended in a naptha carrier with a few other low viscosity additives. The thick grease base in other anti-seize products on the market burn and char at exhaust temperatures leaving sticky hard deposits that actually contribute to the lock-up of exhaust joints. The D A M product carrier evaporates leaving only a film of dry lubricants in the joints that penetrates the pores of the stainless steel.

Are AeroShell multigrade and AeroShell single grade oils compatible?
The compatibility question covers two issues: mixing one grade of AeroShell oil with another; and the effects on the engine of changing from one AeroShell grade to the other. If you typically run on AeroShell multigrade, and you find yourself in a place where only AeroShell single grades are available, you can safely add the AeroShell single grade to your engine. They are completely compatible.
If you run on an AeroShell single grade during the summer, but want to switch over to AeroShell Oil W 15W-50 Multigrade for the winter, you can safely replace the straight weight with the multigrade at your regular drain interval. The idea that you have to stick with the type of oil you started with comes from the days of unusual chemistry when the resulting oils were incompatible.
All approved SAE J-1899 (former MIL-L-22851) and SAE J-1966 (former MIL-L-6082) AeroShell oils are compatible. For example, if you have a high-time engine run on ashless dispersant oils and need to replace a cylinder, you can switch to a mineral oil for 50 hours or so to break in the new cylinder. The only time Shell recommends against switching is in a high-time engine run exclusively on straight mineral oil. Here, a switch to ashless dispersant oil can loosen deposits left behind by the mineral oil.

Are lithium batteries safe?
Since inception in 2009, EarthX has designed their lithium batteries with a micro-processor-controlled battery management system (BMS) to provide safety and performance features for your battery. EarthX is not new to providing lithium iron phosphate batteries. Over the past 13 years, has become the most trusted and used lithium battery in the experimental aircraft market and by working closely with OEM’s and engine manufacturers a like, this BMS has been developed to be one of the most reliable in the industry. EarthX is not only the exclusive provider for the Indy Race Cars, but EarthX is also the first company in the world and in history to have an FAA TSO certified aircraft battery as a testament to the safety and quality of the batteries.
Features of the BMS protection:
- Cell balancing
- Low voltage protection
- High voltage protection
- Excessive Cranking Protection (Heat)
- Short circuit protection
- In the Hundred series, an alert LED fault light to communicate an issue on battery itself or can be remotely monitored with a 12V LED
- In the Hundred series, the BMS board is redundant so there is no single point failure
Battery design safety features:
- Proprietary battery case design with recessed terminals to protect from short circuiting
- Clam shell design with terminals down the center so polarity (installation) is never an issue
- Flame retardant plastic housing
- The state of the art ceramic cell separators to reduce the risk of thermal runaway by 400% over standard lithium cell separators.
Performance design features:
- The widest operating temperature range available
- A rated cells that must meet stringent testing requirements
- True industry standards testing specifications

Are templates required for Piper seat rails?
No, McFarlane does not provide templates for installing seat rails on Piper aircraft because the rail is riveted to the floor of the airplane, making installation easy by riveting directly from under the airplane.

Can ACF-50 be shipped by air?
Only the aerosol is considered HazMat for shipping and is unable to ship by air.
|
Can ACF-50 be used inside light aircraft fuel tanks to provide a corrosion inhibiting coat?
This is not recommended to be used inside light aircraft fuel tanks. This is not an area wehre ACF-50 was designed. It would mix with the fuel and can cause other issues.

Can I fly in the rain with PROP GUARD installed?
Rain will reduce the life of PROP GUARD as the constant impact of the water droplets will eventually fatigue the material, causing it to become more brittle with progressively less ability to absorb energy. This constant water hammering will eventually cause it to shred, starting at the prop tip area. This is a harmless situation that causes no concern in flight, but it will require repairing the PROP GUARD installation. PROP GUARD will tolerate a considerable amount of light rain, but fails fairly quickly in heavy rain. When PROP GUARD is failed by rain, it has already sacrificed itself to prevent considerable propeller erosion.

Can I hook an EarthX battery in parallel or series with a lead acid battery?
No, the voltages are not the same and you will over charge the lead acid battery and drain the lithium.
|
Can I install PROP GUARD on a Composite prop if it is not listed on the approved model list?
Although PROP GUARD has been successfully used by some customers on non-certified aircraft with composite propellers, it is not FAA approved yet for applications not listed on the FAA Approved Model List.
|
Can I install SAFE-HEET on an induction box/Plenum?
On some aircraft (like the Lycoming IO-540 engines) the induction box covers up the oil pan where the SAFE-HEET would normally be installed. It is permissible for the SAFE-HEET to be installed on the induction box, because the box/plenum is a thick casting that can transfer heat effectively.
|
Can I paint over an application of ACF-50?
Per the manufacturer, no you cannot paint over it.
|
Can I replace rivets with screws when replacing my seat rails?
Yes, but there are some restrictions. The screws must be structural screw with a minimum tensile strength of 50ksi. See SAIB CE-90-03R2 for more details.

Can I switch from a straight AeroShell mineral oil to a single grade ashless dispersant oil?
All AeroShell oils are compatible and can be mixed with each other. Many single grade customers try AeroShell Oil W 15W-50 during the colder part of the year, then convert to using it year round. Others, however, choose to alternate between single grade and multigrade depending on the time of year. Either system works well because AeroShell oils are entirely compatible and can be interchanged as desired.
In addition, if you need to replace a cylinder on a mid-time engine, you can switch from AeroShell Oil W single grade or AeroShell Oil W 15W-50 to a straight AeroShell mineral oil for one or two changes to break in the new cylinder. Then you can switch back to the ashless dispersant oil after the rings are properly seated.
If you have a mid-time engine that has been run exclusively on a straight mineral oil and wish to try an ashless dispersant oil, use caution. The introduction of an ashless dispersant oil into your engine could loosen up some of the carbon deposits. So check your oil screens and filters often to ensure against oil starvation and/or oil screen collapse.

Can I use a McFarlane transmitter on a Cessna 152 aircraft?
No, the fuel indicating system on a Cessna 152 is unique and McFarlane has not designed a transmitter for them yet.
|
Can I use my existing prop governor?
Yes, with no modifications at all.
|
Can I use spray paint to paint my prop?
High quality spray can paint has worked well when the prop has been cleaned and the metal primed effectively.
|
Can I use temperature controller P/N 707 with a 220 Volt system?
No, you will need to use a converter that can supply 3 amps at 120 volts to operate both a SAFE-HEET and 707.
