£750! I though that the one for sale at £400 was enough... though I have spent much of my life in Yorkshire. Deep pockets / short arms.

If you are into building your own - or refinishing ARTFs so that it looks different from the herd, it is worth investing in your own spray kit. Compressor will cost £80 + and a small car touch up gun less than £20.

Cellulose £20 a litre but available in 0.5 litre tins. Cheap grade thinner £10 / 5 litre. Celly is petrol proof but needs 2k clear for glow (available in matt / satin / gloss) Buy from a local car paint factors. unlimited colours and gloss/matt. Celly is fast drying and easy to use.

Start up costs are high but aerosol cans are the spawn of the devil, so prone to blockage if not used in one go. and expensive.

Having your own kit and a few primary colours opens up the world of original finishes plus weathering / shading. Buying cheap paints from random sources will soon find your new finish pickling or washing off / lifting due to incompatibility issues.

Maybe not the answer that you hoped for and fully understand if you choose to try cans but just add up the cost before you begin and weigh up how far that would get you along the road to your own kit.

Thread: Moles!
07/04/2018 08:54:23

If you don't 'deal' with them the problem never goes away and not only are there mole hills to contend with but the runs collapse over time leaving holes in the surface.

Trapping moles is a bit of an art. I have had the most success with pincer type traps, 'Talpex' brand best of all.

As with all things, beware of cheap knock offs of proper brands.

If you want any further advice send a pm - some people are sensitive about killing moles - usually people who don't have them

"the stick wasn't simply a walking stick, but a sword stick" and therein lies the problem. An offensive weapon, illegally carried in a public place. Self Defence/Reasonable Force is a defence available to all but requires the observance of some parameters, such as not using and illegal weapon and not using excessive force when the felon is fleeing (Tony Martin scoring double top in that respect)

Impressive finished results. Congratulations on your skill

Derek at the UK Plans site is very adept and scale up/ down from existing plans and pretty unbeatable on price

Thread: Nice Cartoon

I read that negative G is instant disaster for an autogyro. I know from model sizes that up elevator tends to increase the speed of the rotor so maybe forward stick tends to slow the rotor, killing of what bit of lift that you have along with any unfortunate human on board sad

Only a guess though

Someone will be along who knows I'm sure

Thread: crash/emotions

It happens to everyone sooner or later. If its a bad one I collect all the bits and park it in the corner of the shed until the pain subsides. I left a Fokker DR1 over a year and then one sunny day dragged it out and started jigsawing all the bits together. I had it flying again in less than a week and its still flying a few years on.

Thread: 50cc petrol engine prop/rpm figures
27/03/2018 07:59:54

For a model of that span, it would need a very light build for that to be an adequate power plant. I have a 100" FW190 which is OK with a 75cc petrol, it could take more easily. Also, most petrol motor in my experience seem to prefer 10" pitch propellors, the 75 taking a 24x10 and a Zenoah 62 - 22x10. If your flights so far have shown that your engine / power combination is marginal then no amount of needle twiddling or prop changing will make a significant difference.

On the other hand, I would say 6K to 6.5K rpm is not a bad figure for a large petrol engine so I would say your engine is probably in reasonable order. Try a 22x10 but I'm afraid that, from what you say you are always going to be short of fighterlike performance with the present combo.

Thread: Messing about with Mercos'
18/03/2018 08:11:39

I can't imagine that a naked spark at the front of the engine did a world of good to the 27/35 meg radio either.

17/03/2018 22:14:12

Interesting Mercos? This is a petrol conversion from 'back in the day' - although when that would have been I have no idea. I have been around modelling since about 1972 and I have a very vague recollection of Dunham Engineering adverts in the mags. It has a very crude set of external points attached to the front and I believe it to be unrun (No surprise there!)

Thread: S6R & S8R Receivers
11/03/2018 11:27:29

Just to update off this topic for those who may come later, I had several flights with the S8R yesterday. It was pretty calm so not really a test for the gyro stabilised mode but it appeared to work well and the pilot would not know that it was running. Loops and rolls were just the same as with the stabiliser off. It will be interesting to try again on a windy day when the stabiliser has more work to do.

Auto Level was more of a mixed bag. To fly with AL is very different as the model snaps level the moment the stick are released. At full throttle Glow 45 powered model, I could call it an auto crash mode as the model would frequently attempt to enter a violent roll or dive. I was about to give up on this when I tried again at a much lower throttle setting and all worked well. So vibration may be sufficient to 'topple' the RX. Rain stopped play at this point.

In the next session I will have a prop which is a near perfect balance as possible and intend to set the gain settings in Auto Level much lower.

Thread: Correct tool for securing TX switches?

Thanks to all who responded. I had looked at Maplins but gave up after wading through many pages. I'll get one from T9

Hi All,

A couple of the switches on my TX are slightly loose. I have lightly nipped them up with some long nosed pliers and a bit of cloth for protection but its asking to scratch something that I would deeply regret.

Can anyone point me to the right bit of kit for this job please.

Hello Mike,

You were spot on regarding the channel 5/6 option does not activate until the self calibration check has been completed.

I have successfully downloaded and run Sportset but have not tried it with an RX yet. Many thanks for the good advice.

07/03/2018 08:55:03

Thanks Mike, I'll try both

06/03/2018 20:47:39

Hello Mike, I've downloaded the Sportset , after extracting the programme and attempting to run the programme I get a box with the following ' The code execution cannot proceed because the QtCore4.dll was not found. Reinstalling the program may fix this problem' Does that man anything to you?

Just when I thought that the S8R could throw anything more at me, when I've put it back into the test model tonight the channel 5 aileron servo wouldn't move. I have checked on the TX monitor that channel 5 is active, the servo is fine and re run the LUA and checked and unchecked the Channel 5 and 6 boxes. No immediate results.

A bit short on time but cross checking with the other RX shows that its the same. I'm pretty sure that it was all working before QM was activated but I need to double check everything when I have more time to make sure that its not dumb thumbs somewhere.

That was my conclusion but I can't think of any good reason for it being there. Most users will inhibit Ch12 after running the Self Calibration process to ensure that it can't be accidentally initiated when airborne. Even if you didn't do that, what's the point of it when Self Level is there to be used anyway? It gives me he feeling that the Software Writer Geek did not listen to practical Users.

Does your Sportset programme work for all Transmitters? Horus X12 for example? I came across it in my research but rightly or wrongly didn't investigate further thinking that staying with the 'official' FrSky stuff would be a better option. Probably wrong but at the time I didn't want to open another can or worms.

I have come across several references to the missing 'bottom boxes' but as yet, not seen anyone offer a solution. As you say though, it will be something trivial, it just needs finding!

Thanks for the contribution its much appreciated.
