  1. Posting below from Steve Hargreaves which I deleted by acident. Sorry
     
    Well.....fuel is a controversial subject...ask 10 modellers & you'll probably get 11 different answers. Model Technics are a long established & well respected company supplying model fuel to the aeromodelling public so I'm sure they know what they are doing......
     
    HOWEVER....
     
    I personally wouldn't use either fuel, particularly if the motors are new. Both fuels would invalidate the warranty as they don't contain enough oil.....!! Dynaglow is 2% castor & 8% synthetic.... & Duraglo is 6% castor & 9% synthetic. Duraglo would probably be OK in your four stoke but a bit low on oil for a two stoke motor..... Just Engines offer some good advise on fuel here.
     
    Personally I use the Southern Modelcraft Mo glow fuel in both 2 & 4 stroke motors.....2% castor & 15% synthetic....cheap as chips (£12 s gallon) too!! Only problem is you can only get it at the shows (so stock up when you go!!!)
  2. I think these test will be very useful. People recharge their batteries before each use because that is what they have always done not because it is necessarily  the best way to do it. More information on the subject will be most useful.I have to say that the Instant Cells in my Dx6i have on ly ever been charged 3 times in the year I have had it and even then they did not take a any where near a full charge each time.

  3. Well it's not like welding because it is soldering just that the heat is provided by the torch rather than an iron. With welding you melt part of the components to the joined with soldering you don't.
     
    You can use an iron for soldering U/C but it would need to be a big powerful iron or even a gas iron. The main trick with torch soldering is not to get it too hot.
     
    You can also do silver soldering with a gas torch this is stronger than soft soldering and can be used on components that get hot (exhausts). to do silver soldering you need to get the components red hot.
  4. You can use normal solder but an electronics soldering iron will not be powerful enough. I usually use a gas torch to solder my wire undercarriages and thick plumber solder. You can buy a torch from the local DIY shop for a reasonable price. Try something like this. You can probably find cheaper ones if you try. Don't forget to get some flux I use Laco.

  5. What are you trying to achieve with your discharging? I would strongly suggest that you do not discharge LIPOs unless you have some specific need. With the Nickel based cells I would use 1 or 1,1V pre cell i.e. 4.4V and 8.8V for the two packs you mention. I would use about 0.5A discharge rate.
     
    Although I say above "I would" in fact I would not  discharge my NimH as I do not think that they suffer from memory effects. I am also dubious about memory effects on Nicd cells but since I do not use them anymore its not a problem I need worry about.
  6. Starting to look like a wing
     
     
     
    I am never happy with the accuracy of my building. I guess it will get better with practice. I tried really hard to get the slots in the ribs to fit the spars perfectly but the are slightly too deep, although they are nice and tight apart from that. I used a band saw to cut them undersized and cleaned them up with a file.


    Now for some glue!
     
  7. Andy, please do not post in capitals, it is considered to be shouting and will put some people off from replying to your question.
     
    Sorry I can't help with your specific question but hopefully someone who can will be along shortly.
