Hi guys,I am flying Dreamfleet's Cessna CM almost 98% of the time. In DF's model it has no cowl flaps. I a assume in real life it has them but I am not 100% sure. I have never seen a C310 in real life. Anyway I wanted to add them. I simply assigned a cowl flaps switch to an axis with FSUIPC which works fine. You can actually see the engine temp drop when you open them. What I don't know however if the temps are off now as I simply added the colling effect of the open cowl flaps without having the increased temperature rise with closed cowl flaps (someone understands this; sounds a little weird). Should I change an entry in the aircraft.cfg to compensate for this?The more important question is: Open cowl flaps induce drag. But none of that can be felt when I open them now. What if I would additionally map the same axis to spoilers? Can I add spoilers with the aircraft.cfg or does this require changes to the airfile?To make it clear I m not interested in the visuals. The function is all that matters to me.Any help would be highly appreciated. I love this plane.Alex

Yeah, yeah:http://home.t-online.de/home/am.air/ME-Ins...ting-Manual.pdfAlexThis is a real world manual and cowl flaps are mentioned repeatedly.

310 R v. 310 LDF is modelling a 310L. You're reading a manual for a later version. The 310R was the final production variant (with the long nose). That's not to say you can't add cowl flaps in a virtual sense to a virtual aircraft, you can do what you like, but that aircraft does not have them as standard, or as modified.Cowl flaps can be added through the .cfg file and the .air file but if added as `cowl flaps` do not increase drag, or if added as `spoilers` cannot decrease temperature. I don't think you can have it both ways.Hope this helps.Allcott

Thx Alcott,that is what I was afraid of. It's either drag or cooling. Too bad. It is also not possible to double assign an axis to a cowl flap and a spoiler as FS only accepts an axis for one function so I am stuck here. Any other ideas?Alex

The reason the 310L does not need cowl flaps and the 310R does, is that in the 310L, the exhaust is run through an augmentor tube on the bottom of each side of the engine nacelles. That added a minimal ammount of muffling, and increases airflow through the engine compartment, essentially becoming a permanently open cowl flap. On the 310R, the exhaust stacks go straight out the bottom of the cowl.310Q, with augmentor tubes: http://www.airliners.net/open.file/553008/L/310R, without augmentor tubes (and open cowl flaps) : http://www.airliners.net/open.file/561692/L/You can feel free to add speed brakes though. They were not standard equipment, but a few companies produced them ad add-on equipment. They're not too necessary with the 310L's 160MPH gear and flap extension speed, but I used to fly a 310K, which had a 140MPH gear and flap extension speed, and it could be a real challenge getting below 140 to drop the gear. There was a redesign of the landing gear doors between the K and L models that allowed the higher extension speed.Dan

Well, well,very interesting Dan, I really wondered how they did this. Thx.Alex
