  1. As I thought thinking time of course has caused problems. This was going to be the donor plane. Having looked at the issues with this plane I decided to fix this up. I will use some of the parts, particularly the undercarriage, from the mighty barn stormer. Steve
  2. Hi Jonathan, It will be a standard eight ounce tank with a petrol conversion. This is what I am using at the moment but I do have a 10 ounce tank however the way I fly the smaller tank will last for one hour flying time. I am quite happy to execute a couple of circuits and a successful landing and my day will be done. Steve
  3. With the engine mount bolted in next is the fuel tank positioning. A bit of thinking time is required, unfortunately. Steve
  4. Looks good with the engine in place. Steve
  5. With 1/16 shim With 3/32 shim The 3/32 has my vote. Conveniently I can measure the offset at 2 degrees. Steve
  6. Spoke too soon because on offering up the engine it looks like there is three and a half degrees of right offset. I was aiming for 2 degrees or two and a half degrees at the most. The firewall is not yet glued so I will shim it to reduce the offset. Steve
  7. With the tail all glued up it's time to turn the model in the jig and test fit the firewall. It all looks okay so far. Steve
  8. With the two sides joined it is now time for the fuselage jig. All of the cross members have been made and test fitted. As usual setting up the jig took longer than the rest of the process. Next is glue time again. Steve
  9. The undercarriage mounting plates was the obvious choice. This and the former were glued in place making sure that the former were kept vertical. Once dried the second former was glued and the second side was added. I use a right angle at the tail to make sure that the two sides were in line if not I made adjustments so that they were in line. I must apologise for not taking more pictures of the process but I got carried away by a burst of enthusiasm. Steve
  10. ...... Means something I am led to believe but what no one seems to explain. Maybe @Rich Griffcould take this opportunity and enlighten us all, well me at least.
  11. Thanks guys but weight is not something I had a problem with, until now and Christmas doesn't help with all the fattening treats. A new firewall has been made to suit the new location, the slots have all been cut in the ply doublers which have now been glued in place. Before I assemble the two sides I need to work out anything that will be easier to glue in place at this stage. I am thinking of servo tray and tank tray. Also I could make the undercarriage mounting plates. As with many designs there is a section of the fuselage that is parallel and I like to make any components that will hold the relevant formers at right angles, just makes life easier when trying to keep the right angles during the gluing process. Steve
  12. Oh dear me after some thought I remember that I made exactly the same mistake with the Ohmen in that following suggestion that the model would be nose heavy I put the servos in the rear and reduced the length of the nose and that turned out to be a big mistake which I was about to repeat. Both sides have now met each other for the first trial fit. So that I can mark up the positions of the slots for the firewall. I can then cut them out prior to gluing them on, it's easier that way. Steve
  13. That raised a smile John, remember this? These were originally in the tale of my giant stick and as advised, possibly by you, I moved them from the tail and installed in the fuselage exactly as you are now advising me and with the giant stick I was able to remove one pound of lead from under the engine. Although I like making mistakes because that's the way I learn it looks like I've already learned this lesson.🤣 Yes one of these servos in the tail would equate to something like 250 grams of weight at the front and obviously for two five hundred grams putting it this way makes it look a totally ridiculous idea. Back to the drawing board for me I think. Thanks everyone for your advice and you've probably just saved one model, well done. Steve
  14. Both servos will fit beneath the tailplane. Just. Each servo weights 56 grams which should counter balance the added weight of the petrol engine, maybe too much though. Steve
  15. With the last joint glued and clamped that is the second side built on top of the first, not quite identical but good enough. I now need to make a decision regarding the tail, it's definitely going to be a steerable tail wheel and possibly both servos beneath the tailplane. Steve
  16. The pursuit of perfection has got in the way of production here is my latest gadget for cutting and sanding joints. It works well if my latest joint is to be any kind of measure. The top joint is with and the bottom one is without the use of the gadget, proof of the pudding? Steve
  17. I was taught old school, even though it was only seven years ago, and use washers to adjust the thrust lines. As a beginner the idea of using mixes was well beyond me, at the time. It does seem to me that built in thrust lines is just another starting point for using mixes and presumably if the designer is correct no mixes will be required, but if they are I can make adjustments using the Tx. Steve
  18. One doubler test fitted. Take it apart and build the second side on top of the first so that they are in identical then the second doubler. Steve
  19. All the straight bits made and glued in place. That's one side made and if anyone is any any doubt I am not following the plan. The reason being that's my chosen engine, Saito FG 21, has its own mounting directly to the firewall. This has made me not using the wood engine mounts. It is my thinking that the engine mounts are part of the strength. Therefore I'm following Peter Miller method of using a ply doubler for strength. The engine mounts are also used to impart down thrust and side thrust which are now included in the firewall. Next I need to make the ply doublers. Steve
  20. Two balsa sticks glued together. The rest of the chaos is due to me making the parts required. The additional pack included the formers that you can see I just have to make the straight bits. Steve
  21. Yes it must be as I am either ill or having withdrawal symptoms I think it's the latter. Steve
  22. After a couple of days off and my double diamond on Christmas Day. Oh dear time to add some more. Cheat lines and finished with another double diamond. More decoration to come? Or I could start the fuselage. Or I could finish the Peter Miller builds. Steve
  23. Decided on two diamonds and space them accordingly. It looks like the answer is for keep the iron moving and do not allow it to rest in one position. Steve
  24. Thanks Andy, as I was faced with a lot of triangular off cuts I had to give it a go. It worked out well as there were only half a dozen bubbles which quickly disappeared when a light touch with a pin was applied followed by a little bit of heat. I think the problems I've had before is that I was using two much heat and when bubbles appeared I added more heat and made it worse so this time the iron will set at 100 degrees centigrade and move over the film quite quickly. The edges were given special attention with the iron to make sure that they were well stuck. Now I I'm going to practice a bit more by adding more trim to the leading edge. When I have decided on this spacing and the number to have on each Wing it will be finished don't hold your breath Steve
  25. I decided to do the wing tips first simply because they are the hard part. All went well and did not seem very difficult at all I guess this is because I have been building for five years so I thought how can I make this more difficult the answer was covered the leading edge top and bottom in one piece. The results are not brilliant but it is done and more to the point is that I have learned something which is what I try to do all the time. I did find a clear covering hid absolutely nothing and all minor mistakes were opened for all to see. I guess that I need more practice. Looking at the amount of black especially in the center I'm wondering how to apply some yellow covering as trim. Steve
