First flight prototype V1 of the Do-335

whats with the sound at 0:30 ?

That rear prop explains why the 335 is the first piston fighter to have an ejection seat !

Actually the Fokker D23 used a similar push-pull config. Fokker experimented with an ejection seat as early as 1939.

Cool thanks for bringing up the D23. Also Fokker considered the idea of an ejection seat like everyone did since ww1 but did not actually make one. The D23's rear engine overheating problems accounted for it's demise after only 11 test flights. The Do-335 had that nice scoop in the back to solve that problem as well.

One of the fastest propeller driven craft of the time. As I remembered, with Nitrous Oxide Injection, it had a top speed of over 470mph(760kph) but I am open to correction. Wonder if any are left in remotely restorable condition?

Bloody BIG fighter, isn't it? Building more Fw 190s or Bf 109s by 1944 was quite pointless...the latter aircrat was effectively obsolete, and the 190 was getting that way - hence the Ta 152. The Do 335 was the only piston-engined fighter Germany had in late '44 that could've gone toe to toe with P-51s or Meteors and bested them. The future belonged to jets even by that time, and the 335 was in every way the last gasp. Had this fighter seen action, it would have woken the USAAF up....

How many 109's or 190's could they have made instead of developing this though....seems like a huge amount of effort. Oh and I mean the question literally I havent the foggiest idea how much effort went into this.

This is the fastest Propeller plane with the roll rate of a single engined aircraft.

good roll rate indeed,but pitchcontrol???
anyone have an idea?

Good question! I have read that the D0-335 did have a tendency to porpoise @ certain speeds. I don't know exactly why but IMOA it would've been the apparent slight mis-alignment of the engines, therefore thrust lines (in the vertical) and not to mention the off-set prop wash along with that. Makes me wonder if the Cessna 337 has the same problem coz of a similar miss-alignment of the engines, they do make a terrible racket like two pedastle fans fighting one another =/.
