Ummm....huh?  I liked it the way it was      They wanted to make it more like RoF?

I like the FMs. Speeds seem to be spot on and turn radius seems good too. A couple of issues:

• I keep getting "engine overheat" in technochat for the Alb with rad at 100% and temp good at 70 deg C.
• Still can't trim SE5 for level flight at full throttle. Maybe it's historic but I was hoping that having pitch trim would enable to do so. What's the point of having trim?

Speeds may be "spot on" for what they specify, but those speeds are the pre-updated RoF speeds, so we're back to the slow Alb.  RFC people should be happy now.

If they flippin' make the R.E.8 so fast we can't even catch one in level flight I'm going to be pissed.

With regard to the S.E.5a, I don't think they flew around at full throttle all of the time like we do.  You have to wonder if there's some manual somewhere that instructed them what a good cruise RPM was.  I don't think those engines would have lasted very long at full throttle all of the time, but hey, they only have to last us one sortie.

So we'll be going back through all the planes to see what difference the propeller change has made. Climb speeds for a start i imagine.

 

I'm with Vonrd on the Se5a. Can't see much use for the trim except at full nose down to give level flight at around 75% power (will get the actual rpm tonight). I suppose you could back up the trim to give level flight at even lower power settings. Was that really all it was for?

Can't see why any manufacturer would want more up bias on a plane that already climbs by itself at more than 75% throttle.

I don't quite want to defend how they model these planes or how their FMs work, but one thing we have to remember is that the control columns in the real planes were not spring centered devices that pushed themselves toward the exact physical center of their travel in any direction.  Who's to say where the stick was positioned for straight-and-level flight in any of these planes, or what forces were pushing back against them in that condition?

That said, the position of the elevator necessary to achieve straight-and-level flight does appear to be excessively down on almost every RoF plane and is known to be incorrect at least for the Dr.I and probably others compared to the real planes.  IMHO this is a clue to some basic common flaw in the flight engines of both RoF and BoX.  To me it seems like the wings of all planes have too much lift at a zero angle of incidence as opposed to achieving higher percentages of their lift through more positive angles.  This necessitates counteracting it with excessive amounts of down elevator in these sims.  Over all the planes meet all of their performance specs, but how they behave in level flight or in more neutral angles of incidence seems off.  Another clue to this is that planes with lesser wing loading (greater wing areas) such as Dr.I seem more affected by this, while those with greater wing loading (such as SPAD) seem less affected.

Those people with less spring tension and/or greater leverage against their springs (i.e. longer columns) on their joysticks seem less bothered by this for obvious reasons.  If the absence of any ability to move response curves up or down remains permanent (let alone having custom curves for individual planes), having a stick with minimal spring centering force may be the only viable solution.

One other thought about the S.E.5a trim.... perhaps it was meant more to counteract the weight of full bombs, max fuel, etc.  In other words, the plane at it's maximum possible gross take off weight.  Considering that stabilizer trim is mostly a feature of 2-seaters, that could be a reason.  However the Sopwith Triplane is a strange exception which did not carry bombs, to my knowledge.

Had a whole write  up response, but what's the point

Deleted, update was apparently not a new one.  Last one must not have completed properly is all I can guess.

This is the plane that makes me really regret that they do not have individual key-bindings in this game. P-38 gonna be worse.
