  1. I think it will be visible if it is big enough to affect it a lot. Mine was the first low-wing for me and for child_flier, and the first with aerobatic abilities, so it suffered a hard life. Glued back basically straight it always trimmed out OK.
  2. The fuselage is quite narrow at the back, and so not very strong. Mostly that made mine flexible in flapping the tail surfaces around the axis, which would not give the problems in pitch that you are seeing.
  3. Had the field to myself all morning. Rather windy and from the wrong direction, which was good practice. Seven flights and late home for lunch . This has come my way from SWMBO's uncle who used to make models. The classic book, together with some classic plans.
  4. Why do I like particular models? I don't know, I just like them. The others I don't like so much.
  5. Having almost given up, after searching for about an hour on-and-off, it was in the box with the box for the new transmitter. Which also means I have found the receiver which I had forgotten was also mislaid, and the XT90 anti-spark connectors.
  6. Now, does anybody know where I put the new ESC? (It is not with parts for Regal Eagle, not with electronics and ESCs, not with the Savox servo that I got at the same time. Probably with new parts, wherever I decided that was)
  7. It should fly very nicely.
  8. At last pressed go on the last few bits yesterday, arrived today from Slough RC and 4-Max. Great service as usual. When the 4-max one came, I could not think what I had ordered. It was l long package, but I did not remember getting push-rods or anything. The answer, a prop as big as the wing of my first model! It looks a more sensible size against the intended cowl. The motor is a lump too.
  9. Looks great. Fully loaded includes battery?
  10. It is indeed not that critical. The dead spot is straight along the antenna wire, so as long as there is some angle between them the two antennas will cover each other's dead spot. The furthest from the same direction is 90degrees, so that is best, but it is not critical. 90 degrees to eachother has no reference to the model or receiver, it can be in any plane. Thinking about the best reception rather than the dead spot, the best reception is more like a ring donut with the antenna pointing up the hole. Two of those at 90degrees makes something like a sphere (or a jam donut). Reception is pretty much the same in all directions in that case, which is what we would like. Everyone managed with one antenna on 35MHz...
  11. The underlying theory is that an antenna has a dead zone in the direction the wire is pointing. So a second antenna that is not pointing in exactly the same direction has a different dead zone. 90degrees is best, but the 90 degree pair can then be in any orientation.
  12. I am watching with interest here, I have closed loop on a model that came to me built. I ought to re-do it, but I am shying away from it because of the crimping.
  13. Free flight supplies do tube in sizes that slide together, but just looked and they only go to 4mm.
  14. Skylarks going full volume today . Six good flights on my 62" Stik. It is a combination of the bits I liked the look of from several different plans. It has always seemed nice but maybe not quite right. Got someone better to have a fly today - nothing wrong with the model. That gave me more confidence, and with a couple of tips on what to try I made quite a bit of progress in rolls .
  15. This happens to me as well (on mobile). I eventually found it has come up, but on the right of the thread column.
  16. Pretty good there. You will need to get the CG forward to the plan position or it is a handful. I hot glued weight inside the cardboard cowl to over the motor. Stiffens up the cardboard and gets the weight forward. That was enough until I made it even more tail heavy.
  17. How is the balance? I needed quite a bit of weight up front, but it was heavy foam board and over enthusiastic painting.
  18. Down our way I think we had 13 power fixed wing, one Heli and one RC hand-launched glider, plus 6 chuckies. The rain just about held off, and it was at least dry for the photo. Great fun.
  19. I shall do. The rudder comes to the end of its physical range before the end of the servo range, which is a pity because it is a waste of torque.
  20. And so, 4 becomes 2. More than a month just to deal with a hinge and fit two servos! I did not even have to put in bearers or linkages, just screw them in. Both surfaces have too much movement. They are in the servo arm holes that they came to me in, and bringing them in any further they would bind on the clevises. I shall leave well alone there. The rudder really needs a longer plate for the plate with the pull-pull wires so that the servo could be outside the wire attachment.
  21. It is morning, and the elevator does still move up and down.
  22. Now just the long wait to see whether what should be stuck is loose, and what should move is actually stuck...
  23. It has been flown a lot before me, on just the two hinges. But it does not seem to be a lot to hold a big surface so I'll put another one in. There is a pretty substantial bar on both sides of the hinge line, so there are no special places for the hinges. I thought I had lost the servo screws, but they turned up.
  24. New hinges dry fitted Not too bad. I managed to get some slow epoxy at Easter, so that will glue them in. Is grease, oil or vaseline best on the hinge to keep the glue off?
  25. Well, this is really moving slowly. However I bit the bullet today and it has gone pretty well. Cut the good hinge on broken side, and with some wiggling I was able to get that elevator half off the elevator joiner wire. That was a big relief as otherwise I had to take the other side off as well, and the rudder, and the closed loop wires... The Robart pins came out pretty easily. One pushed in (by mistake), two pulled out, one I had to drill out. It turns out that the hinges have been done before, one was off-centre because of a remaining stub. I am trying to get that stub out.
