  1. I've painted several Multiplex Elapor models with Flair Spectrum paints. Never done any preparation of the surface and not used a primer. Depending on the colour contrast I've found 1 brushed on coat covers ok and wears well. 
  2. Clive,   Why do you think a dual conversion is more likely to suffer from electrical interference ?  
  3. All 35meg receivers work on the principle of mixing a local oscillator signal (controlled by the receiver's Xtal) with the RF signal. The output of the mixing is a intermediate frequecny (IF) signal that is the difference between the frequencies of the two signals, and therefore a much lower frequency signal and easier to tune precisely. It is this signal which is amplified and decoded. In a dual conversion reciever this mixing is done twice, once with the RF signal and again with the IF signal using an internal Xtal. So by converting the signal twice the selectivity is increased.  This all happens at the receiver and has no impact on the TX, so a TX will work with a single or dual conversion receiver.  
  4. Can someone please tell me what mess you get when using an airbrush.  I remember using a Flair spectrum dark blue spray can in the garage and everything in the garage got a blue dusting. The door was open to the house as well and I was subsequently banished to the garden for all future spraying.  
  5. With due respects David, I don't think the Blizzard is for beginners.  A WOT4 electric or IC gets my vote for wind tolerance.
  6. With respect to connecting 2 ESCs to a receiver I've wondered whether the best thing to do is to connect each red lead via a diode to the receiver. That way neither ESC will 'see' the other ESC due to the other diode blocking the path and each ESC only needs to supply half the current.  Also, if one ESC BEC fails the other ESC will continue to supply juice. The only downside I see in this is that the diodes will introduce a small voltage drop, which will only a fraction of a volt if a  Shottky diode is used.    
  7. My intended Motor and flight pack are likely to weight less than the original's. Do you think there will be a problem in getting the c of g in the right place without adding weight?  It looks as though there shouldn't be problem because the battery location on the plan looks to be at the c of g anyway.
  8. Hi Chris, It looks klike from the photo's in the orignal RCME artical that the model pictured there has been built with cap strips on the ribs. Is there a good reason for omitting the cap strips from the published plan ?
