  • Bad Raven: Is the issue Turnigy or Turnigy Nano-Tech? I have found that mid-blue Turnigy tend to be low on their stated "C" discharge rating.

  • ched999uk: RaceDayQuads have some cheap but good batts out now. Josh B tested and stats say very good especially at price. HobbyRC have 1300mAh 4S just under £20. Not had luck with Turnigy lipos either!!

  • Reman: Just realised that I hadn't gone through my stored Li-Po's for about a month. I try to visually check them every Saturday, And prod the plugs with a multimeter about once a month. Todays seen 12 more bulging packs go out to the incinerator..... All but one was a bloody Turnigy! Part of me wan't to burn the rest now and just get a load more Tattu packs, But I've spent good money on these packs and wan't to at least get a little more use out of them. :(

  • Bad Raven: Pre MR's I used to buy a lot from J.Perkins. Their website showed all items and stock or due date, go to dealer and buy with confidence. Then they went all "lifestyle" and all the site had were pictures or people. I wasn't after people. I never bought again. Yes, you'd think they'd learn...........

  • ched999uk: Reman sounds like amazon search. I find it ok unitil you want to search by price then amazon falls apart.... You would think both companies would get it right...

  • Reman: It's strange. The original setup they had about 5 or 6 years back wasn't too bad (Except for them occasionally getting accounts hacked), But they changed it to the last one that was clunky and slow, Now they've replaced that with a flashier one that's also clunky and slow ?!?!?! Most companies learn from what they do wrong. I don't buy from HK half as much as I used to, Mainly because it takes forever to trawl through 100 pages of totally unrelated stuff while looking for something you were thinking about getting when you saw it there the previous week !!!

  • hoverfly: I don't think there is a search button on H/King. They updated the site and forgot to  relabel the search button with  Random bo##ocks..
    July 15, 2018, 09:47:35
  • Bad Raven: Agree - The Search is abysmal!!
    July 15, 2018, 08:40:52
  • Reman: I see HobbyKing's revamped their site again...... Shame they haven't made the search function work any better, Or worked out why the whole site goes slower than a pensioner in a Nissan Micra. :)
    July 15, 2018, 08:28:14
  • Reman: How thick is Google? You buy something online, Then for the next week you get targeted adds for the item you've just got?!?! That's the one item you're NOT going to be buying again at that point so it's wasted effort of there part. :)

  • Kellarly: FFS, bought the wrong FC for my whoop. Saw D16 and thought it was EU-LBT ok, but nope :(
    July 12, 2018, 08:32:22
  • Reman: The ergonomics of the TGY feel better, But every new revision of the firmware brought more bugs (The last version had a bug where opening the gimble menu would cause the TX to crash and reset to factory defaults !!!). So what I was hoping was to end up with a stable FS-i10 with a nicer layout.

Tx modification P3s
« on: October 30, 2017, 19:42:24 »
Decided to mod the P3s antennas for hopefully better range.
The 2.4 ghz internal panels have been removed, new external alfa 7dbi paddles fitted.
The stock 5.8ghz antenna replaced with a Silverstone 7dbi high gain omni at 230mm long.
The rp-sma to ipx conector fitted with holes having to be drilled in the top of the Tx plastic casing.

I've got a few trips to the coast planed so I'll range test over some large bodies of water.

Just waiting for postie to deliver two 5W 2.4GHz range boosters, so I've made a bracket to hold them on the Tx.
Fabricated from old spare racer quad nuts and bolts, metal soldering iron stand cut up bent and drilled to suit, stick on carbon film to a plastic shaped backing plate  ~~


That slow boat from China  :popcorn:

Delivered today  ~~
The boosters are 4w (not 5 as last post), I had to cut the plug off the power wires so I could run off a 3s lipos , bit of soldering and fitting to the mount and job done.
Had a quick test with the antennas supplied with the boosters, all seemed good with no loss of video reception. The only issue I can see is the picture on my phone is a bit laggy, I'll put that down to it being a really crapy android device (it's always done it).

I'll give the flat panel antennas a good go next time I get chance.
