Kevin Fairgrieve Posted August 14, 2010 Share Posted August 14, 2010 Would any one be interested in a build thread for the Steve Holland design of the Farmhand 90. I purchased the kit with the instruction DVD a few months ago, and now find the bench clear. The last build a Flair Puppeteer being ready for final painting and assembly. Now I know that the model featured in "the other" magazine but that is what makes this hobby of ours so great. Many great ideas and the sharing of information across the board. I do not build that quickly so the thread may drag on for a bit. Unlike Steve who in the video uses Cyano a lot I will be using Aliphatic for most of the build. There are no plans with the kit as it is all CNC laser cut and slots together like a big jigsaw. I have watched the video several times already to familiarise myself with the sequence of events. So maybe that will speed me up. Motive power is going to be provided by a CRRC 40i. The engine you build yourself. This has already been assembled and is waiting to be strapped to my test bench for initial running in.

Stephen Grigg Posted August 14, 2010 Share Posted August 14, 2010 Yes please build threads are always interesting to me Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 14, 2010 Author Share Posted August 14, 2010 As I progress into the build I will provide a running total of the cost. So far the main expenditure has been the kit and the engine. All prices will include P+P as I feel this reflects better on the real price. I will also include the name of the supplier that I used. Where items are readily avaliable from the "average" scraps box I will not include them. So cost so far. Kit £149.95 Traplet Publications Engine £120.00 eBay Hong Kong Opto petrol engine kill switch 2x Wooden props from Just Engines 18x10 and 20x8 £34.55 Running total = £304.50 Remember this is my first large build so some of you may already have props etc, which will reduce the total.

Kevin Fairgrieve Posted August 14, 2010 Author Share Posted August 14, 2010 Still to purchase. Reciever Probably AR6200 or an AR7000 (yes I use Spektrum) Servo`s X7 Will need to be fairly high torque, In the order of 6kg. No price given for these as I have yet to purchase them. If I go down the AR6200 route I will rob this from one of my "sport" planes and put an AR500 into it. (I will stress that I have had NO issues with AR500`s before we get into that debate) thus lestening the cost. Covering Probably Profilm, but may glass and PolyC the wings as they are sheeted. Your comments on this would be much appreciated. Undercarriage Not looked into that one in to much detail, but probably a nice carbon fibre one from Carbon Copy.

Tim Mackey Posted August 16, 2010 Share Posted August 16, 2010 Without wishing to go down the AR500 is great/rubbish debate again - I think Kevin suggested the 500 for another model he already has .....from which he would be robbing a 6200 unit for this current project Quote Link to comment Share on other sites More sharing options...

Kevin Fairgrieve Posted August 16, 2010 Author Share Posted August 16, 2010 An AR6200 will be removed from a "sport" plane and go into the Farmhand. No AR500 in such a big plane. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 16, 2010 Author Share Posted August 16, 2010 Only a small amount completed this evening. The two sets of undercarriage plates UC1 and UC2 were laminated. The two wing dihedral braces DBF and DBA laminated. The two wing locater tabs W5 laminated. Have tried to post picture`s to my album but they are not appearing. Will try again tomorrow.

Kevin Fairgrieve Posted August 17, 2010 Author Share Posted August 17, 2010 Little progress this evening as I have some concerns over the gap size on the two fuselage halves, which I have informed Steve of. Awaiting a response before I continue. So UC1 and UC2 laminated together and most of the formers and the main crutch have been removed from the sheet. Once again I am having problems uploading pictures. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 17, 2010 Author Share Posted August 17, 2010 Ok then picture upload problem solved. I was using a way to complicated and long naming convention for my pictures. So a few of the parts lamminating. You can never have enough clamps. Edited By Kevin Fairgrieve on 17/08/2010 20:18:26 Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 17, 2010 Author Share Posted August 17, 2010 As per my post regarding the gap between the fuselage parts I can now show the pictures. This is my first lazer cut cut and to be honest I feel that the gap is larger than I expected. As the instruction DVD just calls for Cyno to be wicked in to make the joint!!

Stephen Grigg Posted August 17, 2010 Share Posted August 17, 2010 You certainly havd plentyof clamps there Kevin,do you count them to make sure you havent left any inside Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 17, 2010 Author Share Posted August 17, 2010 LOL. Not brain surgery.. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 18, 2010 Author Share Posted August 18, 2010 After much deliberation I decided to go with a small doubler over the join. I did try to use Cyano wicked into the joint as per the instruction, but it just would not go off. The gap was to much for medium Cyano So I went with aliphatic in the joint with a small doubler over it held with Cyano As this area will not be visible on the finished model the joint is purely functional and would not win any beauty contests. Only time will tell if it was the correct course of action to take. Also the 1/4 square that runs along the top and bottom edges will impart some additional strength. As will the crutch which is going to need some trimming to get it to fit!!! Not sure yet whether that will be at the front or the rear.. Laser cut kit... possibly never again.

Have the day off work today and I am determined to complete the Fuselage. Steve says on the DVD that this can be done in 1 1/2 hours. Probably take me about 4. If the crutch is to fit at the front I will need to take 3mm of the rear. If it is to fit at the rear then I need to take the same of the front and adjust any former location. Which to me will be a no no. Fingers crossed. Quote Link to comment Share on other sites More sharing options...
Kevin Fairgrieve Posted August 19, 2010 Author Share Posted August 19, 2010 I feel a little happier this morning. I have removed the doubler which i put across the joint. Seems that overnight the combination of Cyno, aliphatic and soft balsa has given me a very good strong joint. So I have added the 1/4 square top and bottom.
