I managed to fix the issue with the Ldg gear interference with the help of this great thread that is going on in the workshop. http://www.rcgroups.com/forums/showthread.php?t=1113526

I think I am getting to a lay out that I like. Though the Nacelles are still too large for scale, I think this is the best it is going to get. I might be able to choke the exhaust too much. I am really hoping to avoid filling two more engine holes with EDF's. I think the weight gain would be a bad trade off against slower landing speeds.

Next stop is the nose gear and working out a steerable, retractable mechanism.

Once I have the retract mechanism sorted for the nose gear, I can finally get to building frames, formers and ribs.

I have redone the Engine nacelles twice now. The battle has been in keeping something that looks reasonably scale and keeping the holes big enough to put a decent sized powerplant in them. I also want to keep to 2 EDF's as 4 adds a lot of weight. The design goal is to keep it under 20 ounces per square foot and have the bird fly reasonably scale with good landing performance.

I would also like to allow for an additional 2 EDF's for those who want more performance in the future. Hence the design problem!!

After going through iteration after iteration, I have a design that is a good trade off between allowing for a 65mm fan, and still looking scale at a 72 inch wingspan (might go to 88" yet). Hence, I have finally got it looking good (to me anyways...). Now remembering in my old age that I need to put in retractable gear, I notice that I screwed up on the distance between the two tubes and an area for the gear bay!!!! Now I have to get Rhino to figure out how to stretch the center area by 3/8" !!!!

Research continued on the weekend to find the available data on the Jetliner. I managed to find a site in New Zealand that has a wide variety of flight manuals available including the Jetliner Flight Manual, Brochure, and Detail Spec. It is a paid service on the website, but the price was reasonable for the quantity of data I recieved on this rather obscure aircraft.

The site is: http://www.flight-manuals-on-cd.com/ for those that are interested.

I also think I have secured a copy of Jim Floyd's book "The Avro Canada C-102 Jetliner". Hope to see that very soon.

Lastly, by doing a fairly exhaustive search on the net, I found a fair number of good detail pictures to work from as well. I hope to keep looking as I could use some better colour detail pictures, though it was the 50's

Well, even though I have 2 aircraft to finish, I am starting a third design. The Walrus is nearing completion and waiting on some components to finish up the powertrain. The DHC-8 has to be transported to Salmon Arm from Calgary yet to finish it up as well.

I am starting the design of a 6 to 8 foot span Avro Jetliner. It will be running on 2 EDF's as I think that 4 will be overkill. I have started designing it in Rhino and teaching myself 3D cad as well. It is going to be a fun project and in line with 50 years ago when it flew for real. First jet airliner in this part of the world to fly and once again taken out by the Canadian government!!!
