Hello,I'm on a new 2011 FS Add-on Budget [Wife is the Accountant ] So I need to be selective on what I purchase,With a lot of nice stuff coming in the nxt few months[PMDG, A2A,Flight1 and VRS] I'd really Appreciate your thoughts on the new C340 Flight model and if you find it believable?Thank You **Edit** Sorry for topic misspelling

After two very short hops I've got to say the flight model doesn't feel completely off like the Bonanza did. The only major thing I've noticed so far is that there's a HUGE nose down tendency when the flaps are extended. I'm not entirely sure if that is accurate or not, I've got to watch some videos and read some things to make sure.I haven't yet tested out the high altitude capabilities of the plane. The hops I'm doing aren't very long so I haven't had the chance. At lower altitudes the fuel consumption and range looks pretty dang close.

Has anyone else noticed when adjusting the payload that the CG is all the way to the nose? With just two pilots and nothing else the CG is all the way forward. Wonder if this could be part of the issue...Though I must say, my prayers were answered as I was able to fit the Realty XP GNS530 in place of the two 430s. This is a first! I'm quite pleased. Still haven't had a chance to go flying so will report back shortly.

The 340 is fitted with the split flap system. While these flaps are great for adding much needed drag, they are lousy at best at providing useful lift. When deploying flaps, it is completely natural, realistic, and correct to see a nose down tendency. With that said, it should be very minimal. No nose diving should be happening. Please make sure that you are deploying flaps at the correct speeds, which is very important. Flaps 15 160 KIAS and Flaps 45 140. If you deploy flaps 45 and gear at the same time, there will be a bit more nose down shift.

I dropped in to start a thread on the nose down tendancy, but you guys are already on it. The one thing that seems to stand out is the aircraft in level flight, flys at what looks like a noticable nose down atitude. Thinking it maybe like some aircraft that start going nose down at high cruise speeds, I brought the speed down quite a bit, but it does not seem to have any effect on the nose down look. Unless I am completely reading the Artificial Horizon incorrectly, it also seems to be showing this nose down cruise atitude. FAC

Looking at the FSX Payload Manager, it looks like there maybe an issue with the default CG. With the aircraft completely empty it puts the CG just behind the prop. If I put a 150 person in each seat, it takes 1000# of weight in the aft baggage compartment, just to bring the CG indicator to the front CG limit mark.With just a pilot and a copilot and 2000# in the aft compartment, the CG is about normal, but then the aircraft is far beyond over MTOW.FAC

Unfortunately, the aircraft leaps off the runway on takeoff at around 65-70 KIAS. This is with TOW of about 5800 pounds, Flap 0, Trim 0.0. Looks like the Airfile needs work?

Yes, I agree the Flight Model needs a little tweaking, I find it odd that according to Carenado's website 5 real world C340 pilots gave their blessing to this flight model.http://www.carenado.com/pages/fdC340fsx.htmAs I mentioned in the "Bugs" thread, she seem to fly with too much nose down when in level flight with the autopilot on, and the artificial horizon also indicates that? In the past Carenado has been pretty good in getting updates out, less hope this beauty is no exception.Martin

Airfile needs SERIOUS work. Together with the CG that is wayyyy wrong this plane is not close to the numbers..

They said something similar about the 208 when it was released just to be shown that flight dynamics were wrong and numbers did not add up, so I dont read to much into statements like that.

Hi there,If you wouldn't mind, I would like you to try a few things for me. First of all, the C340 is a pilots airplane, meaning that to fly it right, it sometimes really requires some special efforts and attention. MY RW POH states that at MTOW the C340A is to be flown at the following speeds for take offV1=85KIASVr=90KIASV2=95KIASThese are the speeds that we fly the RW 340 at. I even sometimes rotate at around 98KIAS. Next, the 340 is really pretty powerful. Having 2 310HP IO-520-NB engines. The 38' wings have a wing loading of 32.55 lb/ft² which means that the airfoil is a little less aerodynamic than some other designs. Mix in all that power and in certain conditions you will sometimes have what feels like a take off where the airplane just jumps skyward. Finally, in RW we do usually; depending on load, apply fwd trim on take off. This to help with the power. I usually use about -3 to -4.5* of fwd trim. So if you wouldn't mind, try to fly the airplane at those posted speeds, give her some fwd trim, and finally be gentle with the controls. This is a wonderful airplane to fly, but it does take some practice.

Hi there,Can you give me some more details about your flight when the airplane behaves with this nose down attitude? What are your power settings? Load config? One thing to remember about the 340 is that from the pilots point of view, she has a long forward sweeping nose. So after you level off, it usually gives you the sensation of a nose down attitude. If your power settings are correct, altimeter is correct, and finally your airplane is within weight limits, you should be flying level. If you are in a high speed cruise, the nose will have a very very slight nose down attitude. You can confirm you are flying level by just taking a look at spot view. If when you look at spot view and the nose is actually pointing down, or something like that could you please post a screen shot from the spot view and also in the VC view please? Thanks! I look forward to hearing back from you!

Ok. I'll try as you suggested with an un-modified airfile with the nose down trim. One question - is the -3 to -4.5 degrees trim applied before takeoff roll, or applied as required after V2? The techniques you mention for the C340 are very helpful. Do you have any tips for the approach and landing phase?

Yes, you want to apply the trim before take off. And then as you climb, trim up to maintain climb. What issues are you having with your approach and landing phases? Thanks! Matt

C340 TAKEOFF REPORT: TOW 5440; Fuel 96 GAL/ 639 LBS; Flap 0, Trim -4.5. Vr ~95 KIAS; IMC WIND 0000. This was smooth and much easier to control. This makes total sense and I thank you sir for your input. There are a variety of other aircraft that employ nose down trim as SOP (even transport category, but I did not consider that with this aircraft. The recommendations you've provided from RW ops has given me a greater appreciation of this model. Best, Les Parson

In reference to approach & landing, I don't have any major issues other than a tendency for the airplane to float quite a bit. I've tried crossing the threshold at around 90 KIAS and that seems to work ok. I've ordered a C340 POH, but don't have it yet.
