fly boy3 Posted October 17, 2013 Share Posted October 17, 2013 Hi all, I am building the above model as a winter project, and want to reduce dihedrel fo some aerobatics. Plan calls for 3inches under each wing tip. Would half this fig. be ok. Cheers ps wing span is 72 inches.

fly boy3 Posted October 17, 2013 Author Share Posted October 17, 2013 Thanks Percy. Yes the Moth Minor is bigger again than the Hawk70, but a great flier. Years ago we had 3 at our club all flew very well indeed. OK, I'll go for 1,1/2 inches under each tip. Cheers. Quote Link to comment Share on other sites More sharing options...
John Lee Posted October 18, 2013 Share Posted October 18, 2013 Posted by Percy Verance on 17/10/2013 18:46:56: I'll never forget watching a chap flying a Hawk 70 during an interval at the 1978 World Championships. He flew the model around himself, really close in, control line style. I don't recall him being above about 25ft at any time. Very memorable. That was me Percy! It was the original Hawk 70 with flat bottom airfoil & progressive washout, fitted with a twin plug Merco 60 & MacGregor Digimav IV. I made use of the characteristics of light wingloading, being very stable upright & unstable inverted. It did fantastic negative flicks and could turn in an incredible small radius & enabled me to do proper 3D decades before the term was invented. I was inspired by Neil Williams' (full size) displays & his book 'Aerobatics' which describes in detail the variations on the Lomcevak which I spent hours practicing at progressively lower levels before that day at Woodvale. Today I'm still flying its sister, the Chipperhawk, with a Laser 70, a bit higher now but still sometimes keep everything within the confines of our strip. fly boy3, I still get nice comments about that display after 35 years, trust me its FULLY aerobatic in standard form. Good luck with it. John 1 Quote Link to comment Share on other sites More sharing options...

fly boy3 Posted October 19, 2013 Author Share Posted October 19, 2013 Cheers John, Gobsmacked ! here I am trying to alter the design of a model flown to perfection in standard form at a world champions event. I must be mad LoL. Will build to plan, my Laser 61 will be up front, not as much grunt as the Merco 60, 2stroke, but should be ok for my style of flying. Thanks.

Trevor Rushton Posted August 18, 2014 Share Posted August 18, 2014 Hi FlyBoy3, did you finish the Hawk and how do you find it? I am thinking about getting one to replace my ( now departed) Calamoto and wanted something as docile as that but more scale-like in appearance. I rather like the look of the Hawk or the Moth Minor although not sure if that is currently available. Trevor Quote Link to comment Share on other sites More sharing options...

kc Posted August 18, 2014 Share Posted August 18, 2014 Mike Lovell did a slightly smaller version called the Bandit published in Aviation Modeller International Sept 1999 . His article describes how it was developed from the Hawk but now with semi symmetrical wing section. At 60 inches for a .40 twostroke it looks a good plane for plan builders. Single open cockpit.. All built up balsa - no foam parts. . As AMI is now part of Model Flyer the plan is still be available from ADH. Plan No 18 price 12.50 pounds Edited By kc on 18/08/2014 11:30:39 Quote Link to comment Share on other sites More sharing options...

Trevor Rushton Posted August 18, 2014 Share Posted August 18, 2014 Thanks everone Percy, I telephoned Masons today and had a very helpful conversation with them. There is a short delay on the Moth and Hawk, ( until the bank holiday) but the Kestrel is available and I think I am going to try one of these as I have a spare OS 40 that needs a home. Just awaiting the price. KC thanks for the plan ref; I am checking that out as well. iqon, that Chippahawk looks really good; I have an Airsail Chippie so I want something a little different. I must admit that I like the idea of the foam wings as I'd like to complete the build this season if I can- I don't know if that will be feasible Trevor Quote Link to comment Share on other sites More sharing options...
kc Posted August 19, 2014 Share Posted August 19, 2014 Trevor, I see that a copy of AMI with the Bandit article is being offered for sale, but note Bandit was not the free plan ( that was a Bleriot) Quote Link to comment Share on other sites More sharing options...
Bob Cotsford Posted August 19, 2014 Share Posted August 19, 2014 Posted by Percy Verance on 18/08/2014 21:20:29: Nice. You can't beat a Chippy. Good solid reliable performer. Same fuselage and wings (or at least used to be) as the Hawk 70. are you sure Brian? I seem to remember my Chippie having a semi-symetrical section, but the Hawk wing cores I have are flat bottomed.

namustang1a Posted August 19, 2014 Share Posted August 19, 2014 I had a kestrel it few great on an os 48 4/ ,ended its life by tip stalling on landing and may be lack of pilot skill. I will try and up load a pic if I can find one. any iders on the cost of a new kit/plan pack? Ian Quote Link to comment Share on other sites More sharing options...

Trevor Rushton Posted August 19, 2014 Share Posted August 19, 2014 KC, thanks for the heads up on the article; I will have a look. Ian, I am waiting for Masons to get back to me with the current prices, but from what they were saying the Kestrel will be circa £120, the Hawk a bit more and the Moth Minor a bit more still ( I don't think that they have worked out their pricing strategy yet, but the prices on the web site are not up to date it seems.b your Kestrel looked brilliant; shame that it is no more. It reminds me of my rebuilt Seagull Spacewalker- I crashed it and wrecked all but the tail plane and the fuselage behind the rear cockpit. I made some foam wings, rebuilt the front end and put a Chipmunk cowl on it ( a replacement for the Airsail one). I painted it up just like yours; it flew well but I rolled it into the ground nose first - buried the whole cowl. That was the end of that but it was a rewarding project. Percy, I think you are right about the airfoil from what I have read. The wings have washout as well. Trevor Quote Link to comment Share on other sites More sharing options...

Trevor Rushton Posted August 19, 2014 Share Posted August 19, 2014 Will do Percy - I really ought to finish my Falcon Tiger Moth first, but I have convinced myself that is a long term project so it can stand a bit of a delay - I shall be petrified flying it so a few more hours under the belt on something simpler will do no harm. I will give Masons a call tomorrow and see if I can give them some money. I would like to add some scaleish details - even if its a few dozen rivets and a couple of instrument panels.

namustang1a Posted August 24, 2014 Share Posted August 24, 2014 Thanks for the info Trevor I am guesing by what you have said it is a short kit/plan pack little bit to much for me but would be great to have another. Ian Quote Link to comment Share on other sites More sharing options...
Trevor Rushton Posted August 27, 2014 Share Posted August 27, 2014 I understand that the Kestrel kits are nearly ready; they are making wing panels at the moment, Steve Mason thinks they will be ready in a week or so. Not sure if that applies to the Hawk and Moth Minor. He has not worked out a final price yet. Trevor Quote Link to comment Share on other sites More sharing options...
