Great replies, Chaps. Firstly David. I was aware of AUTO GYRO UK. I wrote to them asking for some drawings or dimensions. They put me in contact with the manufacturers in Hildesheim in Germany who in turn put me on to the chap in Southern Germany, who is licenced to build scale models. He invited me to buy an air-frame kit at 1500 Euros plus delivery! Since then, I have got to know the owner of a full-size MTO Sport at the local airfield who has given me 'carte blanc' to photograph and measure at will. Great guy. Thank you for the info on side-thrust etc. JD8 - I will post some progress photographs very soon. Richard - Thank you for your input. Your note on the forward sweeping mast is very interesting. In order to reproduce as much scale as possible, I will construct one straight one and one as per original. I suspected that the HK head would be discontinued, so I will manufacture one. Once again, pictures to follow and thank you all. Roy

Following my last post, progress has been made. At present, the only plans I have to refer to are from the Pilot's Handbook, scaled up! Photos will be on subsequent posts. I have elected to dispense with the strimmer motor and gone electric. Once I have established the AUW, I will be able to calculate the size of motor required. I have made a base for the cockpit from ply and fuselage formers from liteply. The trike undercarriage is constructed and fitted. I am now looking at building the rotor mast, which has thrown up some questions! Should the mast be 'off-set' as in the full size? How do I calculate the size, (cord and length), of the rotor blades. Having studied the posts by the learned Tom Wright, does anyone know if the rotor heads which he uses are still available or do I have to fabricate one myself? Any help and advice is greatly appreciated. Happy landings, Roy

I have set myself a project to see me through the Autumn and Winter and into the Spring of 2019. Having seen a video of the German Autogyro MTOsport, I was smitten and I have to build a 1:5 scale model. I have assembled a list of requirements and was given, what I think, maybe a suitable motor. This is where the bottomless chasm of knowledge and advice available from the RCME readership comes into play! The motor is a 30cc Big Bear, from a redundant strimmer. My questions are:- How should I produce an 'interface' between the existing output onto which I can secure the propeller? What size of propeller would be appropriate to keep the model reasonably scale? Should I leave the existing 'pull start'? As the rotor disc will be about 2 meters across, what material should I use to construct the blades? I have perused all the existing videos and threads available but would welcome any further information. Happy landings, Roy

Thanks chaps. I've had a good look at the holes and it is clear to me that the screws have been over-tightened. I shall try enlarging to 3.5mm or 4.00mm.

Thanks for that, Steve. Re-tapping was going to be my next course of action.

Help! I've recently acquired an OS 46FX-H. I dismantled it for inspection and to clear some residue and replace bearings and seals. Imagine my utter horror when removing the carb to find that the previous owner had stripped the threads for the fixing screws and 'glued' it in place. Question 1, It is listed as a 40C carb but will any other carb fit?It's going into a heli! Question 2 If not, does any-one know where I can get a replacement carb body. I've tried everything on the internet to no avail. Please help me before I pull all my hair out!

Success! After soaking the offending items in Acetone overnight, I dried them and applied a little heat. Just a small amount of pressure and dismantling was complete. Cleaning the gunge from the parts was the next task and this was accomplished with the help of Cillit Bang! I find the advertisement difficult to watch but the product is great. All I need is some new grommets and gaskets and the motor will run again. Thanks to fellow forumites for the advice. Happy landings and a very Happy Christmas. Roy

Thanks Mike. I didn't serve on Sherman or Cruisers but I know my way round a Cent. They were, indeed less trouble than this OS. I've taken the advice given by Onetenor and soaked it in Acetone. (My wife will wonder what happened to it, when she comes to doing her nails!). It is now free and dismantled. Clean-up and reassemble soon ready to test run next week. See you soon, Mike.

Help! I've recently acquired an OS Max FX 46. It appears to be brand new and un-run. It has been 'stored' in a garage for some time and is seized solid. I've managed to remove the back plate and carb, which is also seized, but I can't move the carb barrel or the crank-shaft. I've tried heat, WD40, and dismantling oil, without success. Has any-one got any ideas, please?

Some new views of the French countryside

Tres bon. -
Isn't it ironic that Germany inverted the diesel engine and will probably be the first country to ban use of it, entirely? Just sayin'

If the manufacturers of the drone can produce a power-pack capable of delivering a package further away than a few miles, it will be so heavy that the pay-load will be minimal! If I order a new fridge from Amazon, how big will the drone be? Happy landings, Roy.

Martyn, I am a German interpreter, so if you want to get it to me somehow, I will translate it for you. Roy

dH2 from scratch

Hi BEB. Thanks for the compliment. Due to other projects like modifying the trailer, finishing other models and having a dry flying field, she has still not yet flown. Rest assured that as soon as it's maidened all bloggers will be alerted. Happy landings, Roy -
I think you'll find that there is an EU directive stating that the only biccies which may be 'dunked' are Rich Tea! This directive will, of course, be ignored by the French!
-
Bert, you might just have the answer there! If the problem reoccurs I will give it a try. Kevin, normally rich tea, but as I am a hard-up pensioner, they were 'poor tea!'
-
Thanks for that, Cymaz. After much umming and ahhhing, tea drinking and head-scratching, I took the whole system out of the aircraft and tested it on the bench........worked perfectly! Wobbled every connection and shook every item......still worked perfectly! Reassembled and installed into aircraft and still worked perfectly. Checked several times over the next 3 hours.............still working perfectly. Therefore it appears that drinking tea solves all problems........ unless you know better! Happy landings, Roy.

I need the help from the massed ranks of the bloggers! I have a 20cc Evolution GX2, equipped with the appropriate electronic ignition unit, in a Chipmunk. It is well run-in and has given great service since last year. Last weekend, it started first time and performed perfectly. When doing the pre-flight checks, I pressed the 'motor cut' button and, as expected, the motor cut! On trying to restart, there was no red light to indicate 'all systems go'. The 5 cell power supply was checked and found to be at 99%. Where do I go from here? Is it a call to Horizon or can someone give me a cause and remedy?

Hi BEB. It's a great aircraft to build. I got some plans on A4 and enlarged them to give me a scratch-build aircraft of 55 inch wingspan. Sadly my trailer is 53 inches wide, so after 2 years of building, the maiden will have to wait a while! You can see my build progress in my album. I shall watch your build with interest.
