Here is a concept 9 piston rotary engine bi-plane I designed. It is a big bird since I used my biggest parts for the body, but I think it flys well for the size and design. Just be sure to get it up-to-speed on takeoff (around 150 mph). I'm planning to reuse my engine in other planes, and I'll share it in a separate posting in a few days since I know many of you were looking for this engine. In the meantime, please enjoy. It was a fun build (Walrus Sr.).

Thank you very much! @JS311
Nice smooth flyer, and I love that engine!!!
Thank you. And you plane from last week looks good. I'll try it out later. @NovaTopaz
Good job. Flies great, looks great, and overall, very good.(also made some new aircraft. Not that important, though. Plus don't want to spam the comments here, lol)
It looks huge! I'll try to fly later today. @XVIindustries
Hey walrus! Check out my latest plane! It's proof that Uss tiny sized objects can fly! Lol
@alstar308 @NotBoeing - thanks for your support, guys!
Even words cannot describe how amazing it looks/ and flies, 11/10
great airplane
haha no problem
@WalrusAircraft OK. Thanks!
Only when you want clean lines and less drag. @Dynimerous
@WalrusAircraft oh OK I see. Is there ever a benefit to using that wheel for a single back wheel?
It was late and I reused my torpedo bomber body. In hindsight I should have used a single wheel an fixed front wheels. @Dynimerous
Great job. Question: why did you chose that particular piece for the back wheel?
@WalrusAircraft ok
Thank you for the kind words, gentlemen. @Nickasaurus @SkipperBing
Thank you, sir! @SpiritusRaptor
Sure... Just give me a link to the work @AeroEngineering
Wow, now this is something else!!!! very very cool.
@WalrusAircraft yeah, I've already removed the two old props, I already figured out the vtol to turn the pistons, the system is genius. I added a bit more power to the main engine, that might be part of the problem. Do you think yo could take a look at it?
Not a new part (but thanks for the compliment). It was blood sweat and tears working the XML to shape everything by hand. About 9 hours worth of time on the engine. @DeezDucks
@AeroEngineering - this plane has some serious power since it is big. I think the front engine is 3x power, and there are two hidden old style small props in the body, each at 20x power. I can remove them for you if you like. Oh, I also gave a VTOL engine hidden at 1% power to turn the Pistons.
@WalrusAircraft 2Ben building this, did you have any torque issues with the engine parts? The reason I'm asking is because I'm building a plane with this fuselauge, and the engine torque is causing it to spin out of control on the runway.
How did you do the engine? I haven't downloaded it yet but is that a new part???
