Engine Purchase

Well I did it. I purchased the LS1 crate engine last Monday. I purchased a FAST intake and Nick Williams 92mm throttle body as well and had them shipped to Michigan where I am going to go in a couple days to pick it up. I saved a bundle by purchasing it in the states even though I have a GM discount. I got it for $900 less there. Amazing!! Here at home I have started constructing an engine test cell. I am doing this because I have a couple of things I want hashed out before I install the engine in my airframe. The ignition is the primary reason that I want to put some time on the engine Continue reading Engine Purchase

Parts for Quickies

I have been in discussions with Dan Yager of quickheads.com and we are working on putting a package of parts together for the Quickie series of aircraft. My company, Effectus AeroProducts manufactures accessories and components for kit aircraft and I am pleased to be able to work with Dan on getting these parts made available for these aircraft that no longer have factory support. We’ll announce the availability and parts lists here on the blog when they become available. Dave

LS1 Water Pump Decisions

I have been spending a lot of time lately thinking through the cooling system and specifically the water pump. On a liquid cooled engine the water pump is a single point of failure. A pump failure means that you are coming down and sooner than you would like. The other thing that needs to be considered when choosing an automotive engine for an aircraft is that a pulley driven water pump is optimized for a very specific RPM range and that is usually around 1000-2200 RPM. This is where the automotive engine spends most of its operational life. You want a liquid cooled aircraft engine to flow as much coolant as possible at its cruise RPM and for the LS1 Continue reading LS1 Water Pump Decisions

Locating the Gascolator

Greetings, Here in Canada we have to install a gascolator in our aircraft to establish a low point for fuel on the engine side of the firewall. I decided to install one of the Van’s Aircraft designed Gascolators as it wasn’t expensive. It was challenging to find a place low on the firewall of my RV-10 because of the design of the  engine mount. The mount I am using for my LS1 installation as well as Vans original design have a tube that runs the perimeter of the lower firewall. This meant that I had to devise some sort of standoff that would allow me to mount the unit and at the same time have the drain clear the mount Continue reading Locating the Gascolator

Low Pressure Fuel Supply Pumps

Hi Everyone, The fuel in my RV-10 is located in three tanks. Left and right wing tanks of 30 gal. each and an auxiliary tank located in the baggage compartment. As mentioned earlier I have installed a header tank on the cockpit side of the firewall. This header tank needs to be full of fuel all of the time as it supplies the high pressure Walbro fuel pumos that charge the fuel rails on the engine. I have installed two Facett fuel pumps in the bottom of the center tunnel on a bracket that has them angled up from horizontal 45 degrees. This is necessary to make sure that bubbles in the fuel do not congregate in or around the Continue reading Low Pressure Fuel Supply Pumps

Custom Dash Top Fan Grills

I have been asked to make up some fan grills for other builders like the ones I posted a week or so ago. They can be customized to your specific aircraft type or I can put your aircraft identification number in the design as well. They are 4.5″ x 4.5″ and have a bolt pattern that is 3.5″ x 3.5″(this can be varied depending on your specific fan size). Contact me if you are interested in having thes made for you. Approximate cost for 2 grills made from 20 guage 304 stainless is US$ 50.00 I ship them flat which means that you have to bend out the louvers. They will have a mill finish as most builders will want Continue reading Custom Dash Top Fan Grills

Where to Locate the Heat Exchanger for Cabin Heat

With a liquid cooled engine now in the works I had to start thinking about how to modify the cabin heating system. The RV-10 has installed tee shaped ducting in the center tunnel that is connected to the heat muffs on the exhaust pipes in the original configuration. I wanted to maintain the same outlets so I had to fashion a heat exchanger and plenum that would allow me to connect 2″ SCAT tubing towards the forward endo of the tunnel as well as aft. I found a MOCAL heat exchanger that along with banjo fittings would fit into the tunnel while laying on its side. From there I made up a stand that Would allow me to anchor it Continue reading Where to Locate the Heat Exchanger for Cabin Heat
