The main problem with these batteries is that they require a totally different way of charging. A lead-acid battery can be connected in parallel with the alternator, and the lead-acid battery will ju
I have a one-way valve in the return line for exactly this reason. This fuel might be quite warm. Imagine when your tank is half empty. The hot fuel will have to make a free fall before it reaches th
while falling to the level of fuel in the tank, Fuel is not compressible. However boiling temperature decreases with lower pressure. So if the fuel is hot, the free fall will promote evaporation of t
Hey! I see my name in this language encoded message! Do you mind to translate this so other people on this list can read it too? My native language is Dutch, but I wouldn't consider it polite to reve
Dear Ivan, Being the builder of the PH-DIY (XS Tri-gear) I have always wondered about the design of the outer flap hinges. It is my impression that the "double" hinge construction of the outer flap h
Same here. I soldered almost everything. Using proper materials and operation there is nothing wrong with soldering. The only caveat is that you MUST protect solder joints from movements. Judicious u
Although your solution might indeed work world wide it is less suitable for Europeans. There are a few reasons for this: 1) Your solution is focussed on more cooling air flow. Unfortunately more cool
Hi, On our recent trip to Croatia we left the aircraft for two days on a very hot airfield. When we came back to depart we discovered that the ASI was reading 70 knots... (Luckily our pitot system is
Thanks! My solution would be even faster to build, if they would change the contents of the box of course. It puzzles me why the contents of the box has not been changed long time ago, when people st
Hi Karl, Thanks! I found the sweet spot of the aircraft is with 27 inch MAP, where it usually cruises with a speed somewhere between 120 and 130 KIAS, depending on C of G and some other obscure facto
As I wrote, this picture was taken when I was still using the stock radiator. The hose routing has been changed when I upgraded to the flat radiator. Actually I now use aluminium pipes for the coolan
Hi Karl, I agree with you. My carbs are 100% balanced, so the whole setup runs very smooth. However, it just feels the engine runs best at 5000 RPM. I called it "smooth" in my previous post, but it h
If I test run the engine the neighbours complain that they don't hear the engine at all, but their windows start rattling in their frames. ;-) Indeed a very low frequency tone! Frans
Ilona and I regularly fly long legs over water. This year we crossed the Skagerak to Norway, we went to Corsica via the French coast (one hour over water), went from there to Italy and then to Croati
I'm afraid you did something wrong... You are not supposed to take off when the warning lights do not come on. Furthermore you are supposed to watch the manifold pressure gauge when you select T/O po
I have quite a few instruments in my modified full width panel. But the upper three holes are occupied by three conventional gauges: 1) the manifold pressure, 2) the fuel pressure, 3) the RPM gauge.
Just like some people like the stall warner, the trim servo, and some other bunch of "recommended execptions" bypassing the master switch? My thought here is that everything could be essential in som
I had the same problem. I could never fill the tank at normal tanking speed. The last 10 liters where a pain, but also at the beginning I could not squeeze the tank nozzle all the way, always had to
Hi everyone, Just returned from a trip to the French Alps. I have had some worrying experience, so I hope to gain some wisdom from the group. What happened is that during the take off roll from a 400
