I have a problem in that bI find it impossible to get the engines to run properly after start. The best I can achieve is about 10-15 seconds the the engine fails. This only occurs after installing the 1.2.1 mod. It seems to indicate that even thought the fuel pressure is indicating normal that there is no fuel flow. The old Carenado fuel fix, ALT -V does not work.
I follow the new start procedures but have given up and can only fly the B-18 with the mod removed.
Any help would be appreciated.
What happens if you start on a runway?
Yep. That works with no problems. May I ask why?
Have you topped up the oil (in weight and balance) before starting?
Have you read the manual?
I read the manual many times but it does not say that you have to do a cold start on the runway. It starts perfectly on the runway so I can live with that. I am interested in why this occurs.

I really love the looks of this plane. I think itâs the most beautiful one in the sim.
Thereâs only one thing that drives my nuts when hand flying and thatâs the trim.
Maybe itâs me, (I use a Honeycomb Alpha Yoke) but just one click will result in a change in VS of at least 500 fpm.
To make things even worse, the effect of one click will only kick in after a minute or so.
Again, maybe itâs just me, but something feels flawed with the trim.
Also trying to trim with engine power doesnât feel right.
(very sluggish and hard to stabilize, but maybe thatâs the nature of the plane)
Just had all these problems with my first flight yesterday.
For me, the engine conking out pretty quickly is due to lack of oil in the engines - bottom half of page 8 in the manual.
When you find the rpm and manifold pressures different for each engine (as I did) - bottom half of page 13 in the manual to repair each engine.
Great aircraft, persevere and it will reward you.

for my part, Iâve found trimming out any aircraft in msfs to be very annoying and borderline impossible.

Iâve noticed the same. Itâs not short vertical displacement like youâd find in turbulence, but long-period, like what youâd find if you were caught in sustained updraft/downdraft. I wonder if the displacement has something to do with the way thermals interact. Or possibly something in the way wind is modeled.
Either way, pretty much every plane is just too pitchy. Not enough static stability. Granted, the lack of airflow causing tactile feedback and aerodynamic centering of the control surfaces and our often meager controls can play into that as well.

Buying Lorbyâs Axis and Ohâs from Just Flights website changed everything for me as far as how much trim is applied per unit if input. For all of the aircraft really. It allows me the ability to adjust the input and that is a huge help.

Exatly. I do this with FSUIPC. Iâm sure it can be done with Spad as well.
I have 2 sets of buttons, one with smaller adjustments and one with larger ones. Actually, the one with smaller ones is a trim wheel.

Iâm going to expand on this a bit: the way trim is modeled is not and cannot be realistic until/unless control forces are introduced. The trim you set causes the tailplane to âseekâ a particular angle of attack and the resultant tail-down force balances the torque imparted by the difference between the center of gravity and the center of lift (which, alone, will almost always rotate the nose down, except in supermaneuverable aircraft).
That angle of attack will vary due to several factors, but the biggest is airspeed. Youâll know itâs trimmed at a particular speed when you can sustain stable, unaccelerated flight at that speed with no force applied to the elevator (or changes to power). In our sim setups, that place is always the null âcenterâ of the spring action, whereas in the real plane, it varies based on (mostly) airspeed.
The way trim accomplishes this is either by servo action, meaning the tab is deflected opposite the direction of the elevator to impart a force that moves the elevator toward equilibrium at the desired angle of attack (think of it as an elevator for the elevator), or anti-servo action, which imparts additional force in the same direction as the elevator is deflected, causing it to feel heavier and return toward equilibrium (usually used to prevent over-controlling and seen in all-moving stabilator aircraft like Cherokees).
If you think about it, these are impossible to realistically emulate without force feedback. The former is not moving the elevator in the sim, itâs just acting as a fine control for the elevator, as if itâs completely separate. And the latter is not countering the force applied, because thatâs impossible without aerodynamic force (feedback) imparted to our controls in the first place. Either way, neither system is even accounted for in the flight model - there is no selection of the type of tab youâre using, so everything works almost as a separate, mini elevator.
So what we have is a work-around that mostly works, but can have some weird results that arenât really in the realm of realistic aviation knowledge. Thus, developers are always guessing and who knows what the outside environment is doing to destabilize things.

This is a fantastic explanation of what we are dealing with!
I didnât do anything regarding trim other than adjusting the flight_model.cfg lines for trim and there arenât any that could cause that behaviour.
To me it seems a problem with the interaction betwin your honecomb and msfs.
Iâm using a DIY trimwheel with a potentiometer and this plane is a joy to trim and betatesters are using just two buttons and none of them have any problem.
Are you using any default profile for your honeycomb? If so, can you try to manual assign your wheel trim to elevator trim? I donât know if it possible to configure trim interaction sensitivity without any 3rd party software.
Try to trim the plane using keyboard to see if it do the same.

Guys, I found a kind of bug in oil leak due to overboost probability calculation.If you overboost your engine over 40, instead of having an high chance of oil leak, you will get one for sure, 100% probability.
Although you should never overboost your engine with so high pressures it doesnât mean you have to have an oil leak.
Iâm working on next update but for now here is a quick fix.
Understand that you still have an high chance of oil leak but its not 100% sure anymore. Remember that the more time you spend on these high pressures, the higher the probability of oil leak you have.
copy and replace Denarq_Oil_Subtemplates.xml file to folder:

I have been reading this topic in hopes to understand how mixture and fuel burn are calculated with this mod. As I understand, in a typical plane with an EGT gauge, leaning the mixture until peak EGT temp is achieved is peaked. Lean of peak is when the temp start going back down slightly while leaning. However, in this plane, to get reasonable fuel burn numbers, lean of peak seems more than 100 deg below the peak EGT temp. Either the EGT gauge is WAY out of range/calibration, or Iâm doing something wrong. Would be great if I had some input on this.
Otherwise, I am tremendously enjoying this mod. Thank youâŠ
As discussed above, LOP operations arenât really a thing for carbureted engines. You canât guarantee your cylinders are all getting the same amount of fuel like you can with fuel injected engines, and you donât have monitoring of each individual cylinder so you wonât know if youâre burning valves until itâs too late.

I wanted to try out the mod, but I couldnât even make it to the runway.
I was able to start one engine. The cylinder head temperature immediately went to the top of the gauge. After less than ten seconds, the engine stopped. This repeated with the other engine. Itâs not possible to restart the engines again. I restarted the flight, I restarted the sim - always the same.
I also wasnât able to set the oil tanks to more than 19%. Everything above is automatically set back to 19. Could this be related to my sim using metric units?
