Default adding an oil thermostat

I had contemplated adding an oil thermostat DIY buy ended up buying the Thermostasis kit that included the hoses and fittings from Aircraft Specialty / Flightline .

I live in So Cal so you may ask “why”. On a 60 degree day my warm-up to 120f is 6 minutes, reviews say this should reduce it to 3 minutes. I also think it is better for the motor to run as close to one temperature rather than fluctuating throughout the flight.

SO you say “what good is 3 minutes” based on 1 hour flight 3 minutes saved is 5% of my engine time, In a 100 hours the savings is 5 extra flight hours. Another way to look at it it’s an extra 100 hours on a 2000hr engine, that 100 hours is worth $1000 on a $20,000 engine.

The install went good, it included a call to Steve to clarify the hose routing. I drained my oil and reinstalled it since it only had 5 hours on it. Then purged the system checked for leaks, dressed the hoses and test flew it.

The added hoses increased my oil capacity 9 ounces or approximately 9%. The added hose and thermostasis unit added 1.75 pounds. The additional oil added .5 pounds for a total weight increase of 2.25 pounds.

I don’t have much time on it so can’t say if it will met my expectations. I flew it today, the start up with an ambient of 80f got to 120f in 2:15 minutes.

Think you have enough hoses? Manifold crossover tube looks extra large diameter...

I live just outside Tampa. I installed the Thermostasis kit, and would highly recommend it to anyone considering it. It drastically reduced my engine warm up times, especially in cooler ambient temps. YMMV.

Just wanted to let RV-12 builders who want a Thermostasis install kit know that we have one on "Special."

A builder recently purchased and then after receiving decided that they wanted to upgrade to the INTEGRAL firesleeve hoses. We never penalize builders for upgrading and so now we have a thermostasis kit that has flown across the country in a box and made it's way back to us. It has never been installed or had oil in it.

This is the 4 hose kit with Standard firesleeve, the oil thermostat and the oil thermostat fittings. Normal cost is $899.95. Since this unit is technically no longer "new" it is being offered at a $100 discount for the kit and free shipping.

Will go to the first RV12 owner to email aircraftspecialty@gmail.com

After a lack of thermostats available for the past 4 months, we are happy to announce we once again have the RV12 thermostasis kits available for order through the website. We updated our website to show this product as once again available, whereas it was previously on an indefinite hold.

Happy building and flying everyone!

I plan to replace my water and oil hoses on my RV-12 ULS at the next annual. Therefore I am thinking to add the Aircraft Speciaity oil thermostasis.
That‘s why I am seeking for your experience report. Are there any issues or safety concerns, any risks I might introduce or just any comments from pilots and builder who have installed this product.
