This is an aircraft that's been around for awhile and I've never put many hours into her, truth be told. There was always "something else" to fly when I was going into tier VII. The reasons for that were rooted in the times; the Senden didn't get a chance to shine in my hands in the environment of small matches. The Senden relies on the confusion and unplanned atmosphere of a wild furball. Given a degree of detachment from the fight the pilot is able to choose situations where they are at an advantage; the small battles prior to 1.9 led to the Senden being focused or avoided to near irrelevance. That is no longer the case and I've had more fun flying the Senden lately than I can recall having in her since shortly after her arrival in game.
The Senden is a multirole aircraft, which means she can mount bombs. For the same reasons you normally wouldn't carry bombs on a Zero the Senden should also fly smooth. A pair of 250kg bombs and the negative influence they have on the Senden's speed, climbing and turnrate can almost never make up for that Senden not influencing the airfight for 2-3 minutes at the beginning of the match. Actually using the bombs on ground targets also tends to leave the Senden in a poor energy condition at a time when the air battle is most crucial. The Senden's primary prey is high altitude heavy fighters. The Senden can operate close to the altitude of enemy heavy fighters and either engage them before they attack or intercept them as they recover from a boom and zoom pass.
If the Senden wins air supremacy it is then free to emulate a heavy fighter and use the same tactics against the faster turning light fighters remaining. If mostly undamaged the Senden's guns are powerful enough for it to take on attack aircraft still flying at the end of a match. Additionally the Senden also may mount Concealing Livery equipment which will reduce incoming AA and tailgunner damage by 30%; not a bad choice for one of the three slots allowed.
And for all this advice I have to give on the plane, I wasn't the one to really showcase her abilities in a pinch; it was Wesrin, who I will easily and gladly admit is a better pilot than I. We decided to dust our Senden off one day and try them in a larger match; despite my poor showing here this was the battle where the Senden felt like something special again for me and I've taken her out many times since to get a better feel for what she can do now. Wesrin was good enough to provide the replay upon my request and I had a great deal of fun making the video.
