I'm feeling a bit masochistic...  TRi_1 by Harry Follas, on Flickr I have two original (1973 boxed) islanders  |

I think the Trislander is uglier than sin, but I'm excited to see you tackle it!

The Trislander is actually quite an interesting machine. It also came with an extended nose to make it look really weird! I've actually flown one, being test flight observer on an Air Tungaru example (from Kiribati) rebuilt at Aeromotive at Hamilton. The test flight had to be at max weight so we had the ferry fuel tanks full, plus half a pallet of cement bags borrowed from Mitre 10! The first take of attempt we realised we had misloaded the nose compartment when it wouldnt rotate! after reshuffling some of the cement back into the cabin it flew OK, seemed really unharmonised - very sensitive in pitch and heavy on the ailerons.
Should be an interesting build - what colour scheme will you use?

I think the Trislander is uglier than sin Wow!! I never thought I'd see the day when Zac called an ugly aircraft ugly! I was expecting you to say you thought they were beautiful like all the other frightfully ugly monstrosities you love so much. |

Interestingly British solution to building a larger aircraft...just use modules from the same airaft production line!
At the Barrier the pilot always seemed to be in a hurry to put the tail pole in before the passengers got out, perhaps a wee bit of a problem with all that weight in the tail

The GBA Trislanders were configured with 16 seats. That allowed 400kg of baggage in the aft cargo area (a standard trislander still had 181kg baggage, for 18 seats). Also if you had 18 passengers and then added a couple of kids on laps, you went over the 19 seat rule (Pt125->Pt121) and needed a 2nd pilot, so 16 seats allowed for a couple of kids without having to move up to Pt121 rules.
Re the tail stand, when they first arrived a senior pilot didn't get the stand in in time, it cost a fair bit to repair and stuffed the schedule (and disrupted quite a few passengers) for the day. I think the impact split the tail cone and maybe damaged the bulkhead.

wet weekends are good for this... temporary lash together of islander components,the fuselage bits are assembled & complete. Its quite easy to do if you cut the fuselages in the right places. I have added an extra window in each side forward but omitted the rearmost window ( would have had to have added it for standard Trislander) as both GBA's long nosed trislanders have these removed as well.I'm going to cut the nose off and extend by a scale 6ft.

They cannot really be accused of being a nice looking machine can they?

They're definitely a strange looking bird, and I think maybe Britten Norman came up with the design exactly the way you're doing it Harry, mixing bits and pieces from existing Islanders. |

I had quite a bit to do with the Trislanders back in the day. I was the last NZ rated pilot before GBA got into them and I have been associated with many of the aircraft around the world. I have worked on them in places like Zimbabwe, Kiribati, Guernsey and Aussie but I know I encountered others in Tanzania I think and similar. I did the engineers' course with Aurigny, Anglo Normandy Aero Engineering, and also did an official factory visit to discuss technical issues. All the guys that operated the type seemed happy with them. They are not at all beautiful all the same. www.pprune.org/archive/index.php/t-450846.html rnzaf.proboards.com/thread/22460/turbine-dart-engined-canso-catalina |

Exactly that! using 2nd Protype Islander G-ATWU as the basis, the Trislander had its first flight at Bembridge on 11th September 1970, and was taken to Farnborough Airshow the same day! |

The wing is quite different on the Trislander but from memory it is mainly to do with extra skins on the upper surface and the mounts. You wouldn't notice the difference on a model. I should have my training notes from the engineering course here somewhere and hope to find them in the coming weeks.  aviadejavu.ru/Site/Crafts/Craft31014.htm |

The problem with this modular method is that you can cut too many modules! I just about cut the wrong tail fuselage component off! Unlike the Airfix Islander, there will be no issue with the Trislander model sitting on its nosewheel (you run out of places to put the lead in the Islander kit). The Geometry of the trislander (long forward fuselage) fixes that + the massively extended nose (still to be fabricated). |

That's very determined of you Harry. Weren't ZK-LOU and ZK-LGR short-nosed versions?

Yep, but I decided a while ago I'd probably do lgc (the blue one) or lgf (the red one), the long nose is better for nose ballast too.

After sanding & shaping...landing gear added. Interesting that this 1973 boxing of the airfix islander has different height oleos (unloaded or airborn) than the latest mouldings...I had to adjust  tRI_5 by Harry Follas, on Flickr |
