mybad,
I recently completed a Pelican build. My build deviated from the norm as I built mine for a twin motor setup. I also built it using an aileron wing. That being said, it came in at 471 grams (16.6 oz) all up weight with a 3S 1300 mAH battery. I would think a poly wing setup would come in lighter than my aileron wing with 2 servos. The twin motors might be the same as a larger single motor....would have to compare weights of each to know for sure. I followed the build docs for using e-tape and laminate on the fuselage. I don't regret doing so because digging out the fuselage to make room for a receiver, tail servos, and perhaps an ESC leaves things somewhat compromised. A few grams of laminate and tape are worth it, in my opinion. Another thing I have learned is that while hot glue is easy to use and fast curing, it is heavy....very heavy when compared to other adhesives that will provide an equally strong joint but with a time penalty for curing. Picking your adhesives wisely will help you achieve a light build. The Pelican is a fun little plane.....good luck! |

Thanks for the replies.
I'm a bit disappointed with the conflicting instructions on the CTH site. The video shows one thing but the PDF shows another. The PDF shows the power pod but the video shows a nose mount. Another place on the site says NOT to use the nose mount. I'm so confused on what angles to set the motor with a light build and maximum self stabilization. To keep it light, I plan on using Foam-Tac and using the micro electronics from my crashed Flite Test Tiny Trainer. Can't get much lighter than that. I'll even be using 4.1g servos. |

FWIW, yes, there are some conflicting differences which can be a little confusing when comparing the videos and the written docs. I noticed this too when I built my first couple of planes.
I also found that it doesn't make much of a difference as both my Pelican and Albatros fly great. On my Albatros, I initially built it with a pod mounted motor. Battery placement was done to keep CG where it should be based on that setup. After several trips to the flying field, I decided to switch over to a nose mounted motor. Using the same motor, I cut the pod off flush with the fuselage and moved it to the nose, leaving the battery where it was. If you think about that, a fair amount of weight was moved several inches. However, the plane flies every bit as good as it did on the first flight. There's lots of folks here, including the owner, that can answer a question or ten should you have them. |

Albatross is perfect for a lazy kind of day
Since I had the camera out to get some footage for Ray, I shot a few minutes of my Albatross. I'm enjoying it much more now that I relocated the motor from the pod to the nose of the plane.
Gotta love how easily it launches. Half throttle it and toss it into the wind. |

Question about these servos which have a higher torque rating than the MG90s but have the same weight. Have any of you tried them. I ordered some and will see how they do.
https://www.banggood.com/4X-Towerpro...r_warehouse=CN MG90s have a 5 day sale going on. This is the cheapest price i have ever seen. https://www.banggood.com/6X-Towerpro...r_warehouse=CN And try this for ESC speed controls https://www.banggood.com/4X-XXD-HW30...r_warehouse=CN |

Lee,
I live at 8,500ft elevation. I'm thinking about an Albatross to teach the kids. Any changes to your recommended motor/prop/battery? I'm considering both wings. Poly for the kids and ailerons for myself. There's so much info in this thread, I didn't read it all. I'll pod mount the motor with the poly wing. Can I conveniently run the aileron wing with the motor pod mounted? By convenient, I mean a quick swap at the field. |

I mix the ailerons and rudder so that I can trade the poly wing back and forth with the aileron wing and fly both wings without having to re-program the radio at the field. You will want to fly the rudder on the right stick the same as you do with the aileron wing.
The Albatross has enough wing area that you can fly at higher altitude and still fly slow and controlled. I did put a bigger motor and am flying with a 2650 3S battery in this video. This video is at 6500 feet.
I have flown over 11,000 feet with a flying wing.

Got a question about where to get the #64 size rubber bands.
We have gotten them from Amazon and also from local office supplies. All #64 rubber bands are not the same. I like the softer darker colored ones the best but sometimes they are hard to find. I think I got the ones I am using now from Office Depot. |

I find these non-latex bands last longer -- especially if you leave them on between outings.
