  • Reman: Got stuck in traffic yesterday. After an hour I started using my phone (And an OTG cable) to look through the media files on a keyring of my old USB sticks. Found one that had the entire run of "Firefly" on it. I got through 3 episodes before the traffic started moving again....... God, That really was an amazing show.

  • mo_miah: Gav- if its a camera ship then TBS crossfire is definitely what you need, the FrSky has limited channels and telemetry options, TBS crossfire has much better features and more channels to control camera gimbals etc

  • hoverfly: I coated a couple of Slipstreams  a few years ago  It stiffened up the wing nicely .On the down side although it prevented dings when i had an high speed"arrival" it left the resin cracked. and the glass lifted slightly.  Well stuck laminate stiffens the wing and is flexible..

  • DarkButterfly: I'm doing laminate, just put my order in for some, also got some balsa wood for the side parts, had to use a kitchen knife to seperate the foam from the busted wood

  • atomiclama: Thanks, can't decide on fibre glass or laminate. Like the idea of fibre for some reason, don't know why.

  • Bad Raven: Usng PolyC, yes
    September 05, 2018, 10:13:54
  • atomiclama: Anyone fibre glass coat their wings??
    September 05, 2018, 09:30:22
  • atomiclama: @DB well you obviously need a bigger motor and ESC, as flying slower is just not possible.  ::)

  • hoverfly: If you put a couple of coats of Eze Kote on the wing before the laminate it sticks really well lifting.. :smiley:

  • DarkButterfly: If it makes you feel better, I’m going to completely refurbish my falcon Evo with new balsa sides and new laminate ~~

The 450/550 (actually 500 across the diag) Seeker is flying, the GPS works well enough (+-10m), and so now we load it down will the odds and ends.
First up is sonar.
I shovelled through my garage boxes and all I can find are 3 SR05';s. I thought I had some 04';s out there but couldn';t find them.
Now my question is -- what is the closest distance between the 2 cans on the ';04?
I thought the ';05 and ';04 were exactly the same size. But now I';d like to know if that';s right.
Reason -- you guessed it. Chinese airframe and the holes drilled in the deck for the sonar DO NOT FIT the ';05s that I have. The diam is OK, the position cut out for the pins is OK, but the main holes are too close together.
No probs to mount the whole board below the bottom deck, but I';d just like to know if the ';04 will fit.
I also noticed on the decks I have the diag holes to mount the little board are also off by around 2 mm too close for the ';05s.
Of course, I bought the ';05 boards from a small outfit in Thailand -- that might be the problem.
