After reading several posts about wing auxiliary fuel tanks I decided to eventually build an internal aux tank. My initial thoughts are to (when needed) replace the passenger seat with a fuel tank. Using 25 - 30 gallons as a target it should be in the 200lb range with the weight of the tank...

I realize this is not Bearhawk specific but there are some great lessons about continuing to fly the aircraft. Greg Hughes from Vans Aircraft recounts a bird strike and loss of his canopy over mountains.

Does anybody know the height of a Patrol on the gear of amphibian floats?

Here is my inventory sheets from my RV-7 firewall forward kit for comparison (O-360 CS.) There are some items listed as deleted. I purchased a mid-time engine that had all the accessories (alternator, CS governor, etc.) so I deleted those from the kit.

This a new AD that affects the Continental engines. https://rgl.faa.gov/Regulatory_and_Guidance_Library/rgad.nsf/0/d21bed1c90f23c54862587f100614917/%24FILE/2022-04-04.pdf

I found this article very interesting as it discusses high CHTs, causes and potential solutions

Nev, I went through a few variations before settling on the AeroSteen pitot tube. It bolts to the forward spar much like the one in Bearhawk book. https://secure.steenaero.com/Store/s...68CF89D388401B I tried fabricating a mount for the Dynon tube but decided to abandon it in favor of the...

Here is an image of an impulse coupling on a slick mag, shamelessly copied from the internet. Slick should have a maintenance manual for these, but if you look at the TCDS for your specific engine it will list the mags and the location L or R. One should have the impulse coupling mounted, I...

My fuel line on the RV runs from the red cube on the fire wall to the carb over the exhaust system. I installed a heat shield on the exhaust to deflect the heat. Here is an example https://shop.vansaircraft.com/cgi-bi...t=heat-shields Here is a poor photo of the installation, you can see the...

I had someone’s print these dies as an experiment. I still need to print a routing/cutting die to see if it will hold up to repeated use cutting blanks. Might be useful for a tool lending program so folks don’t have to make forms. Otherwise the cost probably out weighs the benefit. Unless...

I fabricated an additional mount for an AeroSteen pitot tube. This Pitot tube has a base for mounting to the spar as Bob suggests in the Bearhawk book. I added a side mount that uses the nose rib for additional support. Even with a doubler on the spar web I felt the tube had a little too much...

I searched the site but did not find any threads on the topic. Has anyone installed a stall warning vane in the leading edge?

Is there an increase in the Patrol gross weight if built with the modifications for the floats? The seaplane version.

I am at a point where I would like to drill the inner flap arms to the torque tube. However on the wings I purchased from another builder the flap lever was already welded to the flap torque tube. Of course this means I can not set the flap lever position after drilling the flap arms to the...

As I get closer to finishing the second wing I am searching for EFIS/EMS solutions. I would like anything going into a wing to be done before closing up the wings (magnetometer, AOA support, etc). To that end I read an interesting thread on VAF about a new product that seems promising and is a...

I am considering using a boom style pitot tube on my Patrol. I have considered using the AN5812 style pitot tube and mount but I like the look of a boom style. There are three options that I can find for a boom. 1. Build my own using the AN5816-1 "sharkfin" style. I like the look (old...

I have been using the search feature but have not found any information about auxiliary wing tanks in the Patrol. Is that because no one has done it or that I am just not very good at searching the forums?
