  1. Overlander use rebadged Hobbywing. Or at least they have done historically. Just FYI.
  2. Some more background. I've built several twins. The first was a conventional layout (build log - Double Trouble) and the second was a double fuselage layout (build log - Doppleganger). The twin fuselage is the one with the rudder airbrakes. Aesthetically, I was quite pleased with the fuselage shape on Double Trouble... ...so I'm going to base Orthus on Double Trouble. Not a rehash mind, more an evolution. Double Trouble had a constant chord wing and was very mild mannered. This time around, being happier with twins in general, I'm going to use a slightly spicier tapered wing for better aerobatics. I found the overall size of the airframe made transport easy enough (62" span) with a single piece wing. Obviously it will look a bit different with the twin fins. As an aside, I was very tempted to do a kit bash from the Galaxy Warlock... ...but, it's a big bigger than I wanted, it is 74" span.
  3. RCG can be very "anti". I guess at around ten minutes a pop, that's 800 minutes of air time, (round up) call it 15 hours of stick time. Doesn't seem unreasonable to learn enough skill to consistently pilot something to B standard. .
  4. Definitely not Vega, they were all machined from solid (IIRC) and looked very, very different. What are those bits on the back of cam box? Something to do with adjusting the cam timing? My other bet is that the odd bits are a gear fuel pump - the other photos seem to show a fuel nipple on the far side of it.
  5. My flight log is one page of a larger spreadsheet where I also work out motor setups and record a bunch of other "useful info" like servo torque and fuel cost and lipo cost and some of that can then get used to work out cost per flight of each airframe, and so on. I also do some rough figuring out of build times and build costs in other tabs.
  6. Yes. Takes but mere moments after a session... Helps figure out what I'm actually really getting value from. Amongst other things.
  7. The mythical Orthus had several distinguishing features; for starters he clearly had two heads. But he was also depicted with a tail that had a sting like a scorpion or even a snakes head on the end of the tail. A bit of a beast. Orthus is a project I've had on my wishlist for a while. What will my Orthus be? Orthus will be a twin engined airframe - like his mythical counterpart with two heads. I'm currently undecided between using a pair of Irvine 39, OS 46 SF, or OS 56alpha. But what to do about his other feature, the tail that ends with a sting? Something different is called for. Here I decided a little while back that I would have a go at making this airframe with a 'tail end feature' - twin fins. Why twin fins? Simple - I have had good experience on another project with twin fins providing an airbrake option, by pulling both rudders inboard by 45 deg, allowing for a steeper descent into shorter strips. It's like having a parachute hung out the back. Most airframes would use flaps for a similar function; twin rudders provide an alternative option.
  8. Orthus Mythical two headed dog. The brother of Cerberus; the guard dog of the Cyclops. More soon...
  9. Doesn't look very red. Must be fake.
  10. And what will you do with this information? Learn to walk before running, etc.
  11. Yes, no, maybe. Depends on the particular nature of the job. Some actively prefer a somewhat lower social media profile.
  12. All the thread reply buttons have ceased working for me, if I used Chrome on my PC. As have anything like "edit" or the reaction buttons, or quote - all gone. The same is true on my mobile using the phone's browser. I'm on a different pc for now, using the microsoft browser, but, I can't use that on my main PC, so I'm effectively now unable to post...
  13. Cut hole in fuselage behind lipo, job done. For added bling, use a scoop over the hole, but backwards, so it sticks air out
  14. Generally true C8. Back-EMF increases with rpm (i.e. with more power, for us). Given that the FETs are switching directly on to a coil, this may mean voltage spikes/peaks/noise during switching have different effects at different speeds and loads. Worth noting, our brushless motors are not a switch mode power supply though, and work differently (although both involve fast switching). That said I am far from an expert - this thread could use one...
  15. It's all straight lines. If I remember right, the solid side has a perfectly straight line right from the front to the rear. If you make sure your sheet of wood has a straight edge, you can "just" measure off from that straight edge as a reference line. Then cut the second one using the first as template.
  16. A thought, the remote needle can be mounted literally anywhere. Perhaps a different bracket could be made from metal (recycled baked bean tin) or a printed bracket / holder / adaptor?
  17. Overlander use rebadged Hobbywing don't they? Last I checked they were generally ok. I would stick the ESC out in the breeze for now. Simple, effective - this is a trainer, not a concourse d'elegance winner. If you want to use the scoop (which looks very neat) I'd use it as an air exit, just behind the lipo and on the underside of the fuselage. That would then draw air, and very effectively too, through the model - over all the electronics.
  18. Must admit the engine mount is one bit i can't see the advantage of printing. What will it get you over one of the usual commercial nylon beam mounts?
  19. Seems like it's an easy fix to repair the bust elevator. I wouldn't be writing off that 400 just yet.
  20. I agree with Cuban8 here. Learn to fly the model in its various different attitudes and positions, do not try and pretend you're a passenger in it. As an aside, this aspect of flying is one in which you can make very, very fast progress using a simulator.
  21. Do more useful stuff. Do less useless stuff. Details TBC.
  22. Thing is, nuclear power plant quality software costs a bit much. We never have the forum if we wanted that.
  23. How hot and how cold are we talking? If they've been sat doing nothing, the only other things that could really happen are related to moisture and rust.
  24. Quite. They're not auditors. I'll use the word "wally". Are often best avoided or ignored.
