Hi all,
I am in the 80% finished and 80% to go phase of my RV-8 build. I have been lucky enough to find a pair of Jon Johansen RV tip tanks which have never been fitted to an aircraft. They look like a very fine product and are in excellent condition. I guess about 12 years old. They hold about 12 U.S. gallons each. I understand that at one time Vans marketed these through their web site on Jon Johansen?s behalf. However, Van?s support no longer has any data.
As to be expected, the empty tanks are a little heavier than the wing tips that they replace at about 13 lbs each. Full of fuel we are looking at 85 lbs per side out there on the wing tips.
My feeling is that I should perhaps reinforce the mounting interface with respect to the taxi and take off ground run loads. (I would not envisage ever landing with fuel in the tip tanks. Emergency situations exempted naturally.)
So, has anybody had experience fitting and using these tanks? I would be very grateful for any advice or experiences with the fitting or operating of these tanks.
Many thanks,
Gerry in Oz
