We cannot rewrite the "needs" chart to suit what we have. 100 watts per pound has worked fine up until now, so beware newbies reading that 200 watts per lb is the target. Also, 6.2 lb seems quite heavy for such a small model/missile I think a good target for the model would be 4 - 4.5 lb And in that case, Georges/4 max set up would work fine

1st things 1st Paul, 30 Amps will melt flesh and readjust a heartbeat, maybe to zero, so be careful as any junk power supply is unauthorised, etc etc Nickel Chrome wire of minimal thickness will glow cherry red without breaking And the heat required for foam cutting is no where near this heat, in fact, is barely detectable by eye I am waffling, hoping you consider casing up the 30 amps properly

Ditto on the 50 years Don, you would think that we had learned by now ! I am a small model man and they can play up on us. Lateral balance too is a consideration, but your strip, being an aircraft carrier, perhaps puts the pressure on too. These model types, I do fly in on to the wheels, then cut the motor, I dont even try a glide, but I do practice at height to detect a low speed wing over. C of G may be on the plan button, but it does sound like your build is "leaning back" a little. Weight is our enemy, and adds speed as you know, but I dont recommend we mess with wing incidence packing at this stage as you sound an accurate builder. Add weight, just to try, way forward, up nose as far as you can get it, while watching the balance point is nearby Edited By Denis Watkins on 10/08/2016 09:11:27

No disrespect Don, but C of G is crucial, as always, and are their any gaps in the control surfaces, especially the elevator?, these want taping up Edited By Denis Watkins on 10/08/2016 07:46:21

I only had a few bits Julian, but they were very quick Also, you are protected by Paypal or your credit card company

David, Ian RJ, has given you a more than adequate solution to get you flying. Don't chase this one with yet more and more gear and the extra complications to your flying Get to know the AR636 set up in the way Ian has shown you, then decide if you need more

There is a Model Reset Option On the phone App

The 3 settings include OFF So there are just 2 stabilisations The best flying is when you can just hear a servo change when waggling the wings You can barely see surface movement http://www.modelflying.co.uk/forums/postings.asp?th=118971

Thus closing the throttle Edited By Denis Watkins on 08/08/2016 13:12:19

Itis an odd set up servo arm going past full travel at 75% , past optimum, then starting an opposite travel?

Yes Mike, 4.8 volt regular 4 cell nihms, no problems

Experts will flood onto here shortly David, but their is already a well informed thread on here to help you, not very long ago, look through bud

I keep a regular 4 cell, 4.8volt nihm pack for binding And it works every time buddy

Most of my models are four stroke with dome prop nuts and readily start, at idle, in the way you suggest, with reversed drive rubber. The hole, as you say does not endure a "poor" starting motor for long, and does elongate. If this is to be the preferred method of starting, then ideally it is done at hip height, on a firm model stand, where the starter can be guided and held firmly at right angles to the prop. It is when operated at odd angles unsteadily that problems occur

Hi Karl Have Tx switched off Remove all plugs from the Rx Insert the bind plug in the correct bind socket Insert the power supply to the Rx The Led flashes rapidly Hold the Tx bind button on, and switch on the Tx The Rx will go to a steady Led light. On

For information, commercial soldering of PCB is as we know magnificent due to the temperature controlled ovens used in the process. Some years ago, British Aerospace abandoned soldering wires in the looms of the Channel Tunnel Tractor Unit Control Panels due to breakages caused by vibration in use, and resorted to Crimping. As we all know, when two wires are soldered together, they do become more brittle. The original soft solder has liberated some of the zinc during the heat/smokey process, and what is left is a harder more brittle metal. Proof is when you come to Desolder the job, then it needs much more heat to separate the joint due to the higher melting point of the new solder material Basics are, good clean metal at the joint, good strong heat, applied quickly and as efficiently as shaking hands can do the job, and an appropriate amount of solder, producing a nice brightly finished joint. We know too the electrical properties of a poor joint are less than helpful to our hobby

Repeat, my old Inspiron 5030 is older than your model and runs Windows 10 fine

The safest Windows software is to pay online to Microsoft and download. It is the most expensive way, but it is genuine, is guaranteed, is always upgraded free, and it works

Mozilla Firefox runs on Windows 10 perfectly, either Tower or Laptop, while you decide on the next move

It is a Dell Inspiron N5030, that must be 5 years old if that helps

My old Dell Inspiron runs Windows 10 perfectly now. I had the usual problems with 10 being incompatible with my installed favourite software, but over a week or so I managed to replace these free from the web. I use Firefox for my browser and am not a prolific movie maker or music buff, but everything works that I ask of it.

As Simon says, the " one shot " nature of dry cells does ensure new contacts and a " contact wipe " each time that they are changed and to add Dry cells are 1.5 v, there fore delivering a good 6v through their life. Dont forget, rechargables operate at 1.2 v, delivering a perfectly adequate 4.8 v through one charge, but is worth a thought

I have both Phil, one in card in my flight box, and an aluminium cased one in the workshop, but daft as it is, they are internally both the same guts and both perform the same. As you require something more robust, either recase a soft case tester, or as Jon says, build one. The built one can be assembled on veroboard as the chip does most of the work with just a few components added, or a custom printed circuit board can be obtained.

Erfolg I mean

Hi Erfold, there are a couple of Aeronautical Engineers on this site who will soon come to your air, but in the mean time........eyeballing is not a bad way of designing and positive stagger was in t he main for the full size pilot to see the ground, and our models do not much care if we have negative or positive stagger, so long as the C of G is set correctly, and the control surfaces have adequate areas. Eyeball some more Erf and be an innovator
