Martin Gay Posted July 30, 2019 Author Share Posted July 30, 2019 Another messy bench photo of the prototype fuselage being planked. I used 36 inch long strips to do this one and had to have multiple joins in the planks. Each joint was placed over a bulkhead former for strength, however there is nothing to stop you from using 48 inch long balsa planks.

Martin Gay Posted July 30, 2019 Author Share Posted July 30, 2019 Compare this image of the prototype 36 inch planking with that of the next post. Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted July 30, 2019 Author Share Posted July 30, 2019 This is the latest, "Gamma" build using 48 inch long planks. The finish is much better this time around, probably because I am not rushing it and I have had a bit of practice recently! Quote Link to comment Share on other sites More sharing options...

Bob Jennings 1 Posted July 30, 2019 Share Posted July 30, 2019 Nice planking. You have substantially more pins than I do! Great work. Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted August 18, 2019 Share Posted August 18, 2019 Martin, Have been looking at the plans today so that I can order things up and was wondering what Servo's you've used in the prototype? I've always used Futaba Radio Gear and would like to know which Servo would be most suited as I've always used S148's or S3001's which have always worked out ok but I can see that I will need smaller Servo's for the Sabre build. Any advice would be greatly received. All the Best Phil Beard Quote Link to comment Share on other sites More sharing options...

Martin Gay Posted August 18, 2019 Author Share Posted August 18, 2019 Hi Phil, I used cheap Turnigy 9018MG servos in the prototype model. Any micro size servos will fit in the wing. Futaba 3150 servos (or similar) will work. They cost more though! Quote Link to comment Share on other sites More sharing options...
Phil Beard Posted August 21, 2019 Share Posted August 21, 2019 Martin, Hopefully this will be my last question. What size of Piano Wire and tube did you use for the Tail using the SLEC SL834-R Obtuse Angle Tail Horn. Just going to check with what I've got in stock or purchase along with my wood order and the tail horn. Thanks for your help as I'm hoping to have everything ready and waiting on the 1st Nov to start the build. All the Best Phil Beard Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted August 21, 2019 Author Share Posted August 21, 2019 Hi Phil, You can drill out the tail horn to suit the wire you have. However it must still fit inside the tailplames. For info the prototype used 1/8" (8g or 3.2mm) for the front joiner and 3/32" (10g or 2.4mm) for the rear joiner. The rear needs to be thinner as it is closer to the tail trailing edge.

John H. Rood Posted September 19, 2019 Share Posted September 19, 2019 Martin, may I ask what types of glue have you been using thus far? I'm especially curious as to what works well with the planking process, as in, "sandability". Cheers on a great build. Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted September 21, 2019 Author Share Posted September 21, 2019 Hi John, I use Titebond Original. It grabs in about 20 minutes and is easy to sand. Martin. Quote Link to comment Share on other sites More sharing options...

Peter Garsden Posted September 23, 2019 Share Posted September 23, 2019 On the subject of planking, I have used aliphatic to attach the sides of the planking, and cyano to hold it down underneath as that works well. Look at my Canberra blog or Andy Blackburn's which is better **LINK** Quote Link to comment Share on other sites More sharing options...
John H. Rood Posted September 24, 2019 Share Posted September 24, 2019 Peter, thank you. It's been so long since I've done any real woodwork that I have forgotten lessons learned in the past. It's a long ways back from the House of Sin. So busy talking, instead of actually building. So I have now dusted off my glue stash and found that I need to replenish the Super 'Phatic et al; and today I learned of a new product from Titebond: QUICK & THICK -- new to you all? Heavy? I shall give it a try here and there as I now finish up my A-4 Skyhawk 2016 Glacial-Speed build. Product promo video: https://youtu.be/XLjE9Bbk-bw p.s. Peter, your build blogs are GREAT! Tons of helpful stuff, and lots of dry savage wit. Edited By John H. Rood on 24/09/2019 17:43:21 Quote Link to comment Share on other sites More sharing options...

Phil Beard Posted September 25, 2019 Share Posted September 25, 2019 John, Try Deluxe Materials Genuine Aliphatic Resin, I've been using that for building balsa models for years now. All the Best Phil Beard Quote Link to comment Share on other sites More sharing options...

Peter Garsden Posted October 6, 2019 Share Posted October 6, 2019 Just checking you are bringing plans Mark 2 to the correct scale Martin? I am deep in Jet Provost land at the moment. I am not sure the jets I am making out of balsa will propel it to twice the speed of sound. I have so much scrap wood, I could probably install a log burner. If anyone wants some left over 3/8, I can bring my spares with me to the Orme if anyone wants it? Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted October 6, 2019 Author Share Posted October 6, 2019 Hi Pete, I will be bringing plans to replace the undersized version 15 plans for all those that have requested them to be delivered to the Orme. For those that will not be attending the replacements will be in the post this week. Martin. Quote Link to comment Share on other sites More sharing options...
Martin Gay Posted October 9, 2019 Author Share Posted October 9, 2019 All, During the Gamma build, it was noticed that the plan shows the tailplanes are made from 2 laminations of 1/8" balsa sheet. THIS IS INCORRECT! it should be from two laminations of 1/4" as per the cross section. Martin Quote Link to comment Share on other sites More sharing options...
Andy Blackburn Posted October 13, 2019 Share Posted October 13, 2019 Martin - in order to save the rest of us doing some experimentation, can you please tell us a) how wide your planks were (10mm?) and b) whether you'd use different width planks if you built another one?
