I own an FTB Infinity Evolved 1.7.10 server (current version 2.6.0) with Flan's Mod (futurecraft+simple parts expansions).

BUG/ERROR: When I fly in an aircraft, after a while I hear the engine stop and I fall out of the aircraft (I am NOT pressing any other buttons, like shift or anything). This happens after I take off, and I fall out, the engine stalls, and the aircraft falls out of the sky.

(More details) What happens is, I build the aircraft. OK. Then, I get in, fuel it up. Everything is alright here. I start up the aircraft, and it starts. I take off (pressing/holding W key), and the aircraft is off. The above thing happens, where it either stalls or something, and then I am pushed out of the aircraft and both me and the airplane fall out of the sky.

I am THINKING that it's because the chunks aren't being loaded fast enough? Like the airplane is going too fast, and the server is making the airplane think that it's running into a wall. I don't know, but I would like to know if this is a bug or if I am doing something incorrectly (incorrect server configuration, incorrect client configuration.

I attempted at flying in single player mode, and everything was alright. I spawned the airplane in (creative mode), put in the fuel cans, and off I went. I flew for like 10 minutes, and no errors. It was only on my personal server that it was causes errors with the aircraft.

Thank you for your assistance.

One note, was that this, "stalling and falling" glitch I'm encountering has happened with at least 3 different aircraft on the server. I tried installing optifine to increase my chunkloading, but I'm not sure what I really need to do. At this point, vehicles in flan's mod are unusable.
