Dane Crosby Posted October 26, 2013 Share Posted October 26, 2013 Hi, is Cyril going to show any of the construction of his great Avro 707A here? I would like to see how he shoehorned the wiring in past the intake system. I have just got to build this machine. I saw the real thing as a kit at a couple of military airshows in the '50s and like the look of it. I have never worked in Depron or foam so it will be a culture shock to me. Cyril says in his article that it should not be too difficult to get to grips with. Anyway, today I rummaged about and built an 850mm hot wire cutter out of oddments in my garage and workshop. I found that 12 volts through a (Gibson) 0.012" guitar string (used) worked a treat at about 2.5 Amps. I must nip out to the local bulders merchants and buy some new foam. Next I will make the ply formers prior to cutting a fuselage. Edited By Dane Crosby on 26/10/2013 21:07:41 Quote Link to comment Share on other sites More sharing options...
David Gilder Posted October 26, 2013 Share Posted October 26, 2013 Hey Dane, If I remember correctly, I believe that David Ashby (lord!!!) has some photos on file in his pictures!! Have a look for him in a thread and click on his pictures link - they are there somewhere!! Dave Quote Link to comment Share on other sites More sharing options...

Dane Crosby Posted October 27, 2013 Author Share Posted October 27, 2013 Hi Dave. Many thanks for the link. David has made a fine job of the model. I hope I can get near that quality with my first foam model. Dane Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted November 1, 2013 Share Posted November 1, 2013 In the mag pro-plan article, Cyril makes reference to 'Balance as necessary to get the C of G in the position shown on the plan...' Unfortunately I cannot see any reference to this critical piece of information on the plan. On page 66 the photo caption says, 'The C of G isn't absolutely critical so don't fret too much in this respect'. So not much help there then- but I will try not to fret! Great model though, I will watch your build blog with interest Dane. Quote Link to comment Share on other sites More sharing options...
lightning 759 Posted November 1, 2013 Share Posted November 1, 2013 Hi link to the photos is a great help ,intend having a go at this one will be watching this build for help Andy Quote Link to comment Share on other sites More sharing options...
stu knowles Posted November 1, 2013 Share Posted November 1, 2013 Bit of a BOO BOO if the cg position is not shown but based on other delta models, the cg will be a gnats in front of the undercarriage. If the uc is correctly positioned - when sat on the bench, a gentle nudge should make it sit on its tail. stu k Quote Link to comment Share on other sites More sharing options...
Mike E Posted December 14, 2013 Share Posted December 14, 2013 I too spotted the Cof G issue and have written to the mag asking for inf. be interesting to see the reply I intend building this next year once I have completed a series of winter repairs but it looks really a good looking model and hopefully will do it justice in my first attempt. Like many it will be a new experience with the new materials. Has anyone out there started - hows it going? Mike E Quote Link to comment Share on other sites More sharing options...
Mowerman Posted December 15, 2013 Share Posted December 15, 2013 Omission already corrected. Look in RCM&E December issue page 9. 707 ballance 210mm back fromroot leading edge where the intake meets the fuselage. Also gives control deflections.

Mike E Posted December 15, 2013 Share Posted December 15, 2013 Many thanks Mowerman for the info. I have gone through the December addition and checked page 9 and cannot find reference to the Avro update - maybe as I get mine in the post there was a later correction during the print run.. Anyway many thanks that solves a problem and I am on the way to getting the bits and pieces for a Spring start. I going to use the 10-25 e flite retracts as the weight of under 4 lbs seems to be within the retract spec. Hope this will be ok?

Mowerman Posted December 15, 2013 Share Posted December 15, 2013 Page 9 top right 'A question of balance' under a photo of the model. Edited By Mowerman on 15/12/2013 14:19:39 Quote Link to comment Share on other sites More sharing options...
