  1. Hi Neil, I am so glad that you have had some good flying with Oodalally and are enjoying it. It is a nice model which I why I built a second one with the electric conversion. You have done a very nice of the building and covering. I wish you many happy hours of flying with her.
  2. Lets be quite honest You can go on with all these theories and ideas but in fact slight errors in suposedly identical models will affect things.. The only way you are going to solve these various effects is with a proper wind tunnel. I will give you an interesting event to think about. Early in my air force career I worked on the last Lancasters in the RAF and was able to go in three air tests after major servicing. Part of each air test involved a stall test which involved throttling back,pulling back on the controls until the nose would drop in the classic stall. Then open the throttle and resume normal flight. On one air test the aircraft refused to stall. IT just wallowed along nose high and throttled right back. The pilot tried this four or five times with the same effect. After that they just gave up. Explain that because no one else could.
  3. Actually rereading Graham's statement he is saying that when he applies rudder it is having the same effect as DOWN ELEVATOR. If it is the effect of having more rudder surface above the datum line in theory it should make the aircraft PITCH UP. but his pitches down. I still don't believe that the small difference in area so close to and above the datum line would make the model pitch down. I do appreciate the super fine tuning of pattern ship and the need for ultimate precision of everything but here Graham is talking about a basic model and an extremely wild effect theoretically going the wrong wy if the larger area above the datum line is the cause.
  4. I am a bit puzzled by this. All aircraft have more rudder above the horizontal axis. Now I have never noticed it in any of my designs but then perhaps I don't fly very well. I know that my CAP flew the most perfect knife edge and I don't remember ever needing any aileron correction and one needed a LOT of rudder for that. and I can't say that I have ever heard of it in any full size aircraft. After all, the amount of differential leverage on a rudder considering that most rudders are tapered with more area below the centre line will be quite small.
  5. WE have a club member who built a Ballerina. He complained bitterly about the big gap when he joined the wings. considering I had given him a set of the original instructions he didn't get a lot of sympathy. Then he glued a piece of brass tube into the wing to take the front locating down and FAILED to secure the actual dowel into the tube. He asked the club secretary to test the model. When the sec turned it inverted the dowel had slid out and the wing came off. The builder blamed the club secretary!!!!!!!. I will make no comment!
  6. Hi James. You build the first wing complete with R-1.. You then build the second wing but DO NOT glue the root rib in place until you prop the first wing up in position and only then glue in the second root rib. This way you get a perfect fit of the two wings at the correct dihedral angle. You can then add the second wing top leading edge top sheet.
  7. I like builders!!! As regards to taking longer I would also give you my favourite quotation from the late great Bill Winter's Purple Plan: "So long as you glue one piece of wood to your model every day it will get finished" I build fast because I have been doing it for a very, very long time and I certainly do not achieve the degree of perfection that others do. At least my models fly well...usually!
  8. Hi Dave I am using the 4-Max recommended set up. 3547 1070. 12X 6 high performance wood and 3300 3S battery. It works well. Have fun, it is great on electric power. probably slight;y better then the i.c set up but it is a looooong time since I flew the i.c version
  9. A Sargent Major was giving a recruit a severe telling off and finished up by saying "See that window up there? Go up there, drop your trousers, stick your backside out the window and give your brains an airing" Some time later the Sargent Major saw the recruit and asked him. "Did you follow my orders?" Recruit "Yes Sargent Major" Sargent Major "Did anyone see you? Recruit "Yes Sargent Major, The Station Commander!" Sargent Major "Oh1 What did he say?" Recruit "Good morning Sargent Major."
  10. Not necessary.Just steep bank for a moment and because the guns had to aim in front of the aircraft they changed aim to anticipate where the aircraft would be when the shell detonated.
  11. Another snippet of WW1 bomber flying. When the anti aircraft fire (Archie) got a bit close go into a steep bank but keep flying straight ahead. Archie promptly started shooting where they expected you to be..way off in the expected position after the turn.
  12. It certainly was NOT prop hanging. What most people seem to have missed with their comments of "only a couple of rounds" is that the Fokker DVII would have come up under the DH4 and started firing as it raised its nose. The bullets would have started hitting the DH4 from somewhere towards the front and tracked back along the fuselage. Consider that my father had several bullets in his lower right leg (THe scarring was in the shin from just below the knee down towards the ankle. He also had a bullet in his right elbow (Could never fully straighten his arm) and a bullet through his right shoulder. So much for "just a couple of bullets" although some could have been from and earlier attack. Incidentally he also shot off his own aircraft's rudder horns but luckily the DH4 also had secondary rudder horns which still allow some rudder control. In another battle another incident. After the fight the pilot held up his right hand. The forefinger and index finger where hanging loose. He then held up his left hand and the same fingers of that hand where hanging loose. Bullet had smashed into the top of the control column. I believe that that pilot was madam Tussaud's son. Although I could b wrong.I know one of his pilots was that man.
  13. Try tell that to my late father (see above) It would pull up and fire a brief burst before falling away. On the particular raid 9 aircraft were sent to bomb a bridge. Orders were to bomb the bridge and climb for height. Three never took off, 3 turned back due to engine problems. 3 bombed the bridge.Two turned back but disobeyed instructions to climb....they never made it back.My father's pilot climbed for height. See my previous post on this subject as to the final result. Quite frankly I think I would trust the accuracy of my father's description of events rather than all the theories being posted on this thread. After all, he was there!
  14. Looks great and very happy that you are enjoying her...but please add a pilot to bring it to life
