  1. Hi Steve, Apologies for the delay in responding. That sounds like a great idea, it had never occurred to me that this could be a solution. I'll give it a try and report back, though it won't be for a few weeks as I've got too much on at the moment. Thanks Mike
  2. Hi Rich, Thanks for your reply. I did wonder if the thrust line was a bit in the high side. If you do come up with any ponderings, please let me know. In the mean time I will confine myself to little hops. Having said that the weather today was very wet so no hopping. Hi Steve C Thanks, I did have an action man initially, but it was the wrong scale. I'm considering a carved foam figure like Rich did of Ken Wallis. I suppose a Sean Connery foamy would be the next best thing Cheers Mike
  3. Hi Rich, At long last.....It's finished. Thanks for taking your blades to P/Borough for me to copy and your support through this build. if anyone else is interested: Blade length (total) 726mm Length to bolt hole 720mm Width 60mm Thickness 6mm The hang angle is 17 Degs at AUW with a 2200mah 4S battery. AUW 1484 grams Rich, I've mapped the hang points (top of nose wheel under the fus and top of mast) to get the C of G, against the thrust line. The thrust line is 40mm above the C of G. Do you think this is OK? if not, any suggestions? Hang test photo (a bit bleary though) 17 degs Here's the finished Little Nellie. I have to say... "I'm pleased" will try some test hops (not flight) tomorrow.
  4. Hi Murat, Thanks, but I wish they were 3D printed!. They took ages to make. The flame throwers were made from plastic overflow pipe with wine bottle screw tops hammered into a cone shapes for there front, the flame thrower exit was made from cone shaped depron. The rockets pods were made from a Berroca Orange tablet container cut to size with the rockets (tips only) made from wood dowels covered in a strip of white insulating tape and the tips painted red. The guided missiles were made from thin cardboard sheet rolled to a tube with 1/16 ply for the fins, and a balsa nose cone. All the white bits were spray painted, they needed several coats. In all it took a couple weeks to do. If you/anyone following this thread has a 3D printer....use it... the accessories were a pain to make.
  5. Its been very slow progress, but the paint job is done. there is still a lot of building to do though.
  6. Hi Rich, I'd be interested to see a video on calculating rotor loading as I'm sure others would too. Cheers Mike
  7. Hi Rich, I'm sure I'm not alone in wanting to see the build to completion. The Twister looks really good and the name is very apt. A potential mass build I wonder??? I look forward to you getting to the blade set up in particular as I hope it will give me some tips for Little Nellie. Cheers Mike
  8. Hi Rich, Thanks, it's slow progress at the moment. Can you give me an rough indication of the weight per blade I should use? Yeah...I'm not very impressed with this platform, the previous version was clearer and easier to access Cheers Mike
  9. Hi Rich, Thinking ahead regarding the blades, I read somewhere that 2 bladed gyros need to have tip weights? is this correct? also do the blades need shims for negative pitch just like 3 bladed models? Cheers Mike
  10. Hi all, Now the weather is warming up I'm back on the Little Nellie case and can work in the garage without freezing my extremities off. The fuel tank is now completed. It's made from pink foam and depron then glassed. I've added captive bolts epoxied to the foam for fitting to the fus. The next job is the prep for painting and making the weapons.
  11. The pod/ fuselage has been a bit of a challenge, as I don't have enough suitable foam to carve it from, so I used balsa planks over a some formers. The end result is not great but I can live with it, and it's light enough. I still need to rub it down a bit prior to painting. I carved the nose cone from the last of my pink foam stock. I think I'll have just enough to carve the fuel tank and rotor head cover. The gaps in the balsa planking was filled using a mixture of Talc and non shrinking dope mixed into a paste. The resulting filler is easy to work with and when cured easy to rub down to a very smooth finish and smells great (bonus), I then glassed it, but as yet I've not completed the pre painting prep. Glassing isn't one of my strengths, so it needs some rubbing. I may be able to live with it though. We'll see.
