Did a testflight to see what will happen when you're running low on oil.


These tests are fun to do.. I have run the Cub, and P-47 out of oil (not on purpose).. Those times were not fun. On the Cub I almost had 400 hours on that motor, and thought I had enough oil to make it to the next airport. Started to watch the oil pressure gauge fluctuate.. Went to myself "Hmm that is weird" and kept flying. Then eventually it just seized up.

An even better experiment is to purposely overheat it, and watch it become a stanley steamer till the engine bursts into flames. I did that in the Spitfire on accident. At first it started out as a low hiss, and me wondering what in the world the noise was. Case in point watch the temp gauge.. The P-40 and P-51 have similar relief valves as well.

Now I had my second generator change. 104,6 hours on airframe and engine.

A little more than 50 hours from new generator to a broken one. It lasts approximately 30 hours in green condition, then shows yellow for about 20 hours until it fails. Really nice.

90 hours and the crankshaft is borderline between green and yellow? (Though that's only a guess.)

I just got a from "like new" (0.0 engine hours) to "nice condition" with Spifire in 3 hours due to crankshaft wear. And that with flying it carefully (take-offs at +2 (2400 rich), climbs +1 (2400 lean), cruise -2 to +0 (2000-2200 lean) and temperature below 100 deg C at all times, and with high octane fuel). Monday specimen much? The only other alternative that I could thimk of is that there's still some leftover traces of the shutdown wear bug left and the engine gets damaged when idling low with hot oils (waiting for the fuel lines and carb to drain out). Should I maybe idle it at elevated rpm and kill it immediately after the first few coughs (even if there's still some fuel pressure left on the indicator)?

Anyway, I'd like to reach 100 hours one day. But as long as I'm too lazy to back-up .DAT files, I'm doomed to lose engine hours when I run into invisible objects on carrier deck, or if I try to hone my crosswind landing skill with the plane in a hurricane, etc. It's especially annoying with Mark I as it doesn't have A and B subvariants - just a single save slot for aircraft condition. If there's any way to work around a duplicate model with duplicate save slot (not necessarily a separate save slot for EVERY paint, but at least two per variant), I'd like to try out. Same of course goes with B-17, P-40 and B-377. I'd like to practice emergencies and crazy landings without the hazzle with .DAT file back-ups. Then again, if I know beforehand that I'm about to fool around, maybe I could actually use that minute to save the old state before launching the game. Maybe even create .BAT script to do the back-up and restore with a doubleclick of the mouse...

Look at it like you would do real flight documentation. :wink: Writing your own logbook.

So I think, I have to collect all the hours again...
