  1. I've often wondered if it refers as much to the effect on the copper. It usually manifests as crumbly black conductors.
  2. Watching these posts with interest as I should be picking mine up tomorrow.
  3. To be fair to Peter, I did raise the possibility in the first paragraph of my first reply! 😝
  4. They've been almost universally adopted on high performance full size gliders at significant cost so there may be measurable benefits on larger models. To my mind, they are an ugly addition to the beautiful clean shapes that competition gliders evolved to in the glass fibre age.
  5. Made a lot easier by another's experience a week or so ago!
  6. As a wise man once observed, there are no stupid questions, only stupid answers! It's an easy mistake to make if you are used to connecting the battery to a dedicated slot - although as you probably know, it's only for convenience as the power rails are commoned in the receiver.
  7. I think you have the lead in a socket marked VCC? This is not the throttle channel. Funnily enough, someone else new to electric power made this mistake very recently. Unlike an IC setup, the ESC needs to power the receiver through the channel that supplies the throttle channel position data. I believe this is channel 3 on this radio.
  8. Perhaps post a picture of your setup so that we can see what is plugged in to where. I assume you’ve connected the ESC lead to the throttle channel? I can’t say for certain but I think this transmitter complies with the normal direction - Futaba kit needs the throttle channel reversing before starting the process. You may need to train the ESC to the throttle channel - most require you to connect the battery with the throttle wide open, wait for the beeping sequence to stop/change, NO PROPELLER FITTED PLEASE, and then close it. The beeping stops/changes once it’s complete. Best to go with the ESC instruction leaflet which will hopefully have been supplied.
  9. You should be able to use any similar spec. servo. Just be aware that there are variations in quality so look for a known make. If you go for Hitec you will probably need to reprogram your transmitter to reverse them but whichever you use, check for correct movement before flying!
  10. We don’t normally use fully sealed bearings (there might be exceptions of course?). Some front bearings can be replaced with 2RS bearings but always with the inner seal removed. I would normally replace like for like though - air leakage may be a problem for two strokes and four strokes without rubber seals may possibly be designed that way to encourage internal air/oilflow through the tappet area. The rear bearing would normally be open as it needs all the lubrication it can get - especially with four strokes. On the other hand, I believe that even 2RS bearings aren’t truly sealed - the seals are only clipped into place.
  11. All I can really report is that I haven’t had any failures, problems or concerns with any I’ve fitted. Mostly OS and clone single cylinder 4 strokes ranging from 20 to 120 and a Laser 62
  12. They have my vote too. Very often orders have arrived the next day. Good choice of bearings too - whether right or not I’ve tended to go for C3 bearings recently (slightly larger clearance) which I’m led to believe are better for high speed/temperature use.
