  1. I've previously suggested exactly the same regulator Andy but you still have the same heat dissipation problem, LDO doesnt help that. 🙂
  2. Amp-hour gentlemen 🙂
  3. As C8 has said, on a 3S pack the 7805 has 7.6 volts across it. As little as just 130mA is a watt of heat dissipation. I wouldnt! 😁
  4. I think I need a new camera Brian, although all the flying shots were (unavoidably) taken into the sun The Canon S3 has been great but its old and a service would probably cost more than a new camera...

    This combo from Aliexpress is the very same bundle as the above from 4-Max but at half the price. Its not similar, its identical - except Aliexpress gives you an extra servo! https://www.aliexpress.com/ssr/300000512/BundleDeals2?spm=a2g0o.productlist.main.60.3818d3606OrDA8&productIds=1005006414999169:12000037122260213
  6. Or.... depending on your gear, we (our slope group) mostly use a single lipo cell, without any booster or regulator.
  7. If you're ever passing, Newark Air Museum has one, and a Fred too!

    Just a reminder to read the spec fully and not make assumptions as I did (!) The 4-Max package arrived promptly but the 2212 is a 28mm motor not 22mm. To be fair it does say so in the spec (which I missed, my fault) but the name "A2212" is deceiving when you're used to 'conventional' descriptions - for example Georges 'CF2805' motor is 28mm as you'd expect, his 'PO-2826' is 28mm, yet the A2212 is also 28mm. In fact the A2212 is almost exactly the size of the Babe-Bee fuel tank which is ok. I've since found other 'value pack' combos on Aliexpress and Banggood, at even lower prices, so much choice! 😄 .
  9. Until you give it enough to arc (thousands of volts) voltage doesnt come into it 😉 So yes, a standard switch harness will be fine with an 8.4v lipo. A lipo can deliver much more current than a NiMh so you will see less 'saggng' under servo loads - but use a suitable wire guage for the load, otherwise the resistance of the wires causes a slight loss of voltage across the length of the cable. When soldering up, be extra careful to avoid shorts - even a small lipo will happily deliver enough current into a short to completely burn out a standard switch harness.

    Just an observation, I had another look on Georges site and this pack seems to be remarkable value for money and would be a perfect Cox .049 substitute. 22mm is about an old pound coin. I'd probably run it on a 2S 450 rather than Georges suggested 3S (3S is 80 watts, = two Cox Babe-Bees!) https://www.4-max.co.uk/value-power-package-2200kv.htm ...in fact I've ordered one for my stash 🙂
  11. Why Spektrum? if you're starting out on a budget there are other options...
  12. The V8 R4 is a great receiver. The servo plugs go acrossways with negs to the middle 4: S + - - + S S + - - + S It will be powered by the BEC when you plug the ESC into the throttle channel. To bind, theres a tiny button near the aerial, press with a blunt toothpick whilst powering up. Bear in mind its the old V8 protocol, check your tx does that.

    Polarity

    With a current-controlled driver, twins can even be fired up using just the pins of the two plugs, in one, across the crankcase & out the other, polarity makes no difference 🙂 .
  14. C8:>>What do AI Bots achieve? When you ask an AI such as Copilot to deep dive an obscure topic, if theres little information to be found it will often offer to post questions on your behalf via online media such as forums. Some users will accept this offer and so the AI posts a half-informed or poorly phrased question on the forum based on what little knowledge it has. Responses to the post will be fed back to whoever asked the original question. Like this, where I'm looking up the 'Nibbler' computer released by DigiKey in 1978:
  15. "Noomhobby" looks like another AI post David. New registration, one post, bad English.
  16. Maybe another AI post? register, ask one question, then never respond?
  17. Not sure how to approach the event Rob, Cherry Lane? do we go down the narrow lane to park? Not sure my van will fit, is it as narrow as it looks? 😀
  18. ...yet another alternative is 'stacking' banana plugs, wouldnt be my choice but its an option...
  19. Its probably just a power track that has blown, have you popped it open for a look Peter? If so you should be able to link the break. As to why, most likely through drawing too much current, either through greedy servos, binding linkages or an actual short somewhere. Though theres no power coming through, are the servo signal outputs present? if so , maybe reconnect power externally.
