Piper PA-34-200T Seneca II

Welcome to the Seneca!

My entry to the GA Challenge is a replica of the iconic Piper Seneca in the form of the PA-34-200T. It is a twin-engine aircraft powered by two 200 hp flat-six turbo engines, the Lycoming IO-360-C1E6 on the left wing and the Lycoming LIO-360-C1E6 on the right wing. The counter-rotating engines result in a balance of torque and a very comfortable flight.

Two seats in the front and four seats in the back offer space for one pilot and five passengers or pilot + co-pilot and four passengers. The seats in the rear feature a club-seating arrangement with a refreshment console including cupholders and a table.
Behind the seats in the very back is a storage compartment for luggage or cargo.


Features:
  • Custom wings with custom control surfaces including trim-tabs on rudder and elevator
  • Detailed interior with working cockpit controls and instruments
  • Realistic artificial horizon that actually works (free to download on my profile)
  • Working switch-panel
  • Headbobbing in pilot and co-pilot view
  • Realistic lighting including landing lights, nav lights and strobe lights
  • Custom detailed landing gear with suspension
  • Quite realistic but also balanced flight performance and specifications

Performance:

Cruise speed: 202 MPH @ 25000ft with 75% throttle
Maximum speed: 250 MPH @ 25000ft with 100% throttle (real structural limit is reached at 235 MPH)
Stall speed: ~80 MPH @ sea-level with full flaps and landing gear extended
Take-Off speed: ~90 MPH with half flaps
Rate of climb: 1750 ft/min


Controls:

Pitch = pitch up/down
Roll = roll left/right
Yaw = yaw left/right
AG1 = Nav Lights toggle
AG2 = Strobe Lights toggle
AG3 = activate rudder trim
AG4 = activate elevator trim
AG8 = gyros for the artificial horizons (should be left on at all times)
VTOL down = flaps down
VTOL center = flaps up
Trim = adjust the trim of the currently active trim-tabs
LandingGear = toggle landing gear and landing/taxi lights

Take-Off:
I recommend starting with flaps halfway down and 100% throttle. Rotate at 90 MPH and begin to climb. Pull gear up as you gain altitude and put the flaps up at 110-120 MPH. Adjust elevator trim as needed.

Climb:
Climb between 10 and 15° at full throttle and adjust elevator trim to hold the angle.
Level off at your desired altitude and reduce throttle down to 75% (indicators on the RPM gauges pointing straight up). Adjust elevator trim to stay level.

Landing:
Approach at 110-130 MPH, extend the landing gear and flaps while adjusting pitch trim as needed. Your throttle should be between 30% and 45%.
When close to the runway your elevator trim should be maxed out with the slider at the bottom. Start to reduce your speed to around 100 MPH. Pull up (flare) before touchdown and reduce throttle. Land with the rear wheels first, let the plane roll out a bit and then apply the brakes.

    Wow, as spefyjerbf said, I am surprised I never saw this. I am glad now though. Probably the best build I have seen that is under 1000 parts. And that part count is awesome! :P

    @JamesBleriot I like that idea. Might consider building one when I have the time.

    @BRuthless Can you build a DC-3 with a full interior, ideally less than 1500 parts?

    @BRuthless @BRuthless oh I see, I hate asymmetry too:)

    @Benny3053 LOL, I actually thought about making it five letters so it's 100% correct, but on the other hand it would make the lettering on one side of the wing much wider than on the other side, and I hate asymmetry. Plus I couldn't imagine anyone here would actually notice such a minor detail! :D

    @Viper3000ad Yes, there is a veeery slow roll in flight. During the weeks building it I couldn't find the cause, I guess it's some error. You can counter it with a bit of rudder trim though and it adds a bit of realism, as planes in reality also don't fly 100% perfect and need to be trimmed. However on the ground I never had an issue, except for one time when one of the props magically increased it's power. I corrected it and since then it has always been going straight. You could check if your CoT is offcenter and adjust engine power to be equal if it's the case.

    Awesome build. Just awesome 👍👍👍👍👍 but....there is one thing that triggers me...... correct me if I'm wrong but this is not a German registration. You need one more letter e.g. D-IPWN

    One of the best cockpits I have seen so far. Very good build for the landing gear, maybe I am doing something wrong because on takeoff it slightly turns in Y axis and in flight has 2 decree roll to the right. Other than that it is amazing plane. Very hard work congratulation.
