Re: Turbo dial & throttle combinations

Hi, For decent do this, and you should be good: cruise rpm; turbo dial @ 8 (this is to prevent carb icing); auto lean mixture; adjust throttle to keep about 26-27 inches MP. This setting gives good decent performance, and doesn't damage the engine in any way. Hope this helps, Yes, it helps. I thoug...

Turbo dial & throttle combinations

Hello forum. Finally bought the Accusim B17, eventhough big planes usually arent my thing. I think i can fly the plane pretty nice already dispite having it only for a day now, but one thing bugs me. It's the manifold pressure selector. I was left with the image it was making this plane easy, but it...

Re: Could someone analyze my flight

BTW a tad off topic but if any of the developers are reading this i would like to throw out an idea for future: Current a2a Spit uses 1940s oils? It would probably last longer on modern synthetic oils? Right? That as an option would give much longer engine life for us who are interested in flying sp...

Re: Could someone analyze my flight

Thanks a lot killratio! First of all i do the runups on the runway for two reasons: i have nose in the wind, and my engine is nearly at takeoff temperatures (more rpm i demand, more oil temp i require). I make sure though that the temp is no more than 90 after the run up and immediately after that i...

Re: Could someone analyze my flight

Very nice. Looks like you've done a good job in your flying. Did you three-point or wheel land the Spitfire? Three-pointers are best, as there is no risk of prop strike. I haven't been able to guage my engine life perfectly, due to my testing for the review on Flightsim.com required me to wreck it ...

Could someone analyze my flight

If somebody could say am i doing anything major errors here. So my typical flight goes like this: +9 outside temp. Winds calm. 100 Octane fuel I start my MKII, i use pretty low throttle, something above rough. Normal oil grade, oil/coolant 100%. RAD open. Pretty soon i add power just enough the plan...

Re: Oil Pressure Dynamics...

I believe the min oil temp is 15C for a take off. So 30C should be more then enough. Yes. 15 is the minimum. But that was a wartime minimum. Modern checklists requires at least 40 celsius. Flying the spitfire by the book and numbers is pretty easy, but the ground operation is not. As my engine work...

Re: Oil Pressure Dynamics...

In general, use regular oil for all but extreme hot or cold conditions. I use winter oil (thin) if the oat (outside air temp) is below 20 deg F and summer oil (thick) if oat is over 90 deg F. What you have to be most careful of is a cold start, as you have a very slim margin to idle that engine unt...

Re: Oil Pressure Dynamics...

I think i am finally getting a hang of it: More than 5 hours and the engine is Like New. Ive been flying in +5 OAT, and i found that NORMAL oil gives me the best oil pressure. Over time the engine will gradually lose its oil pressure i think, so should i at some point change to more thicker Summer o...

Re: Flying tips and advice available if needed

Hi all again. If i want to maximize my engine lifetime on my spit, so should i get the oil temp to 30+, even if it would require an additional shutdown and startup procedure? In another words, would that additional shutdown/startup wear off the engine less than a takeoff with 15+ oil temp and let's ...

Re: Comments and Questions about the Spitfire

That's exactly what i was trying to do: Clear the engine before shutting it down. If i do as the manual tells me to do, i end up having fouled plugs. Of course it is just a spark plug cleaned -text on a hangar, but still. If i rev it, and then cut the throttle and cut-off the engine before the rough...

Re: Comments and Questions about the Spitfire

I'd have few questions of my own. Can i/should i taxi using auto lean mixture? Like on regular planes, you usually taxi with leaned mixture to avoid plugs fouling. This also might reduce engine heating? (Or increase it, depending on the mixture, dunno) The A2A Merlin seems not to work at idle revs. ...

Wings Of Power 3: Spitfire torque effects

Hello all. I've flown A2A Cub for a longtime, it was neat but rather too simple for my taste. Today i bought the latest Spitfire and that is AWESOME. Only thing that bugs me in it is the lack of power-feel inflight. On takeoff it feels like a fighter plane, but in the air it feels lazy and especiall...
