Managed to squeeze in two additional FM tweaks - a small ver. 6.5 addon - for an early Dr.1 and the standard, "gaskammer" variant used in early 1918. More info. and package available at the following link (no need to register at CombatAce):

NOTE: If the DiD Campaign deities choose to include the early Dr.1 on the "official DiD FM list" (located in the relevant post under the "casual campaigns" thread) - I recommend testing/evaluation of the "gaskammer" variant too since use of that one after the early Dr.1 provides a more natural upgrade than switching back to the stock FM of the gaskammer Dr.1 variant (stock FM, very generally speaking, is somewhere between the early Dr.1 and post-Nov. 1917 batch, performance-wise - and for simplicity's sake may be used to cover all of the bases in the DiD Campaigns for the Dreidecker jockey - for those who like to keep their FM lists simple).
NOTE 2: two to three percent right rudder recommended on the tweaked Dr.1 variants to fly straight, otherwise they tend towards the left, to fly in an "x" pattern - also depends on the weather and other variables. Flat turns work acceptably to the right on the early Dr.1 and "gaskammer" - more difficult to maintain on the 150 hp mount available in the ver. 6.0 FM package. Flat turns to the left are not very good on any of the variants, will fall into a spin eventually.
