......except that a fully stabilised aircraft on final approach should not dip, climb or turn at all when the autopilot is switched off. That's the entire point (I would assume) of preparing the aircraft for landing.

Its for sure something that needs to be adressed. I just wanted to point out that its not so dramatically, that it's a show stopping bug.

I'm going to delay buying this until they add full hardware FMC capability. I use spad next to power my home cockpit. For an $85 addon, I find it ridiculous they chose not to support hardware FMC's.

Just flown a few test circuits the F70..

*With calm winds it’s absolutely solid and a joy to fly, no issues with speed control at all.

* On autopilot disconnect there is a marked pitch up, most undesirable, especially in a RW aircraft equipped for LVOs and autoland, so that’s an issue that needs addressing.

* I added a slight crosswind at 18 gusting 25, that’s nothing too taxing in the RW, AP & AT off, between gusts it was stable, however when the gusts hit I saw a loss of 50kts IAS on one of them, for the exercise I continued fighting it down to the ground. There was some nasty pitching and speed deviation.

Needless to say that wasn’t realistic behaviour for those conditions.

I want to just make it clear though I don’t blame the F70 or just flight for this behaviour at all, it’s without doubt the base sim.

I say that with confidence as I’ve seen the exact same sort of behaviour with other swept wing add ons, namely the Cessna sovereign, while flying in real weather with a gusty 20kt quartering wind, I had a wing drop turning base and rolled inverted, losing the aircraft.

I must admit I’m starting to get a little frustrated with the aerodynamics in the base sim to the point I’ll now only fly swept wing jets with the wind turned off.

I only fly in calm conditions, so that is one issue that I do not have to worry about. However, the "pitching up or down" on final approach after disengaging the autopilot is definitely something that I could not accept, so I will be interested to see what JustFlight can do over the next few days/weeks. To be honest, I am surprised to hear of an issue like this, considering that the aircraft has been in development for a long time.

Having said that, the Avro RJ Professional was permanently consigned to the maintenance hangar because of an unacceptable "bouncing" (pitching up and down) during descent with the autopilot engaged. I absolutely detest "bouncing" (which is why the PMDG 777F is also temporarily unavailable for flight duties). I know that many of you do not see this issue with the Avro RJ Professional, but it completely destroyed my enthusiasm to fly the plane. A real shame.....

I still haven’t purchased the F70/F100 quite yet (trying to master my new A2A Aerostar and the new FJS 732 in XP12) but I DO have the F28 by JustFlight - that little beauty seems to do everything right and don’t recall having any issues in wind with her, but want to test later now?

In any case, the F28 flight model and F70 should be very similar in terms of wing at least, which (if OK) should give JF clues to help tweak the F70/F100 as needed? Not sure of all the differences between say the F28 and F70 (and wish there was an excellent history book on these to join my book collection!).

That awesome 737-200 I referenced needed some tweaks on release too, and they’ve been busy tweaking and releasing as needed, I’m sure JF will do the same.
