  1. The Lemon is a good unit to start with Harry. I have installed two, and corrected two that gave trouble, due to human error. Level installation is vital, and the trouble came about due to misalignment by the fitter trying to cram one in the model. This, from your instructions, will save you much headscratching.
  2. I have no doubt there was a change made by Mark Robinson's addition, but to measure a fair db reading, do it with the motor on the model on open ground. To me, he completely invalidated the test using the bench and near to the stone wall. The mouse did work well on my OS25 way back when, on the then Precedent Bi-Fly.
  3. Have succeeded using a jubilee clip Martin But use it very carefully
  4. I came across this in the early days of Li-ion charging, and it was then selected on the charger as Li-Lo To deliver 3.6V/cell Max LiPo voltage level 3.7V/cell Max So as not to overcook the Li-ion at that time, years ago.
  5. Everyone on here knows that it is " tin hats on " to speak about props, as there is always someone waiting in the wings, to swoop in with a comment, as they know better. Your prop choice is narrowed by where you fly. If you are in a noise sensitive area, then a 12 x 7 will certainly hold the revs back. To get off the ground smartly, perhaps, thick grass, normal conditions, then 11 x 6. To move more quickly in the air, and perhaps quieter, then a 12 x 6. There is more to consider with good ground clearance, but try an 11 x 6 for a good few flights and you might just like it.
  6. You have to ask yourself Andy, how many lives do we have, and how precious time is for flying. Please don't even consider turning up 100. All your club mates will have one or two washers in their flight box that you can have.
  7. With the Gyro switched ON The Elevator has much reduced throw
  8. Agree with Nigel, just because the way my brain works, would set up 2x 2 way switches. Switches on outer right and outer left So that I reach the minimum distance to cut either left or right motor.
  9. Have tried to stay out of this Jeff, as we all know, rearward C of G is a nightmare. That tiny iddy biddy tailwheel is not going to make a near 8lb model unflyable, so leave that where it is for groundhandling. Could you get a wings off side pic so I can compare to mine, like this, and see the builds are similar. My C of G is just online with the front of the wing tube.
  10. It is very tempting to carve up a quick soft former Martin, but that is just the opposite of what you should use that can remain intact under the heat and pressure required to mould a canopy.
  11. Thanks Alan, I am the L two seat. Jeff's S is correct being heavier and the 100 mm C o G about right.
  12. Apologies, I typed S, but am sure mine is the L.
  13. I hope there are not 2 Seagull Extra 300s Jeff OS46AX 480grm Is this the manual As it does look 75mm and wing tube position
  14. Jeff, I have one of these models, and fly it but it has a glow motor, not electric. It is 1lb 3oz lighter than yours at 6lb 6oz The C of G is bang on the Wing Tube at 75mm And I never add weight to the cowl, as it can break through or pull the cowl off. There is a small weight at the front of the engine mount but our set ups are different. I have regular JR servos in the wings Hope this helps
  15. A flying buddy of mine has been using his KOPILOT for the 1st time, and like your self, set up, but he did so in the pits. Well the model climbed to height and circled the pits, yes,in front, behind, in front, behind, thus going into dead airspace behind us. Return to home had everyone in the pits running for cover. Best advice is to set up in the centre of the runway ! ! ! Or at least the pilots box.
  16. There is no doubt Dan, at all, that visiting the slopes gives you an appreciation of flight and time on the sticks, like no other activity, But, for half my club, and myself, if we returned to the slopes, we would need air lifting down by the emergency services. For a novice, if sloping appeals to them, then they should try it. Some flyers remain on " page one " all their lives, but they enjoy their 3 - 5 minutes in the air. Some flyers are good, but never quite " move on " from reliably getting into the air, and getting back, but they too love the day out with the lads. A few flyers become great at it, always smooth, always go home intact, but there is no guarantee that all flyers will become good flyers. My advice for the " A", is not to fly about aimlessly, but at least once or twice a day, to try to fly the " B " schedule, and tidy up all other manouvers.
  17. Apart from the BMFA recommendations not to overfly people, livestock and buildings, It is common safety sense not to overfly these, yet some people chose to do so, for example airports. Now, as requests not to overtly have been ignored, radio operated and GPS sensitive equipment will be jammed. As the equipment flown senses loss of signal, it should land, and cannot return home due to GPS jamming, And the recovered craft will be used in evidence. Jamming is not indiscrininate, but is focused at a prescribed range around protected areas and can be adjusted from 100m to 2km. I for one would not chance being airborne.
  18. No longer needed with microwave transmission Edge, as you suspected
  19. There are more than a handful of literate lads on this site who contribute common sense daily, and could fill the Magazine monthly, with useful, informed articles. At least 5 or 6 of you stand out, and should consider contributing to the magazine. Your skills shared daily include builds, materials, printing, scale builds, scale flying, gliders, glider set ups, Tx and Rx set up, charging packs, purchasing, motors, ESCs, I/C motors, purchasing, tuning, cleaning, servicing and On and on and on.
  20. Apologies, I missed the edit and a line of two was missing from above. Microwaves from our gear do not bounce off the atmosphere like many radio waves and they don't much like any obstacles. This makes our transmission pretty unique to where we operate and that we see our model. RF jamming is similarly unique, would be short range, no way over the horizon, through forrests, and huge buildings, and would need an antenna for each frequency target so is not simple to operate sucessfully, but our gear uses specific frequencies and the jamming would match that. Flying outside the fence should leave you ok but fly beyond the fence and expect interferrance .
  21. The idea behind modellerss using 2.4gig was for point to point, line of sight communication with the model. The transmission is very directional, and line of sight means not very far away. This results in 1000s of users on the band not interfering with each other. Fly towards an airport, a military base or Buckingham Palace and you will encounter problems.
  22. Remember Christmas 2018 Britain sent troops to its second-biggest airport after an unprecedented attempt to cripple Christmas travel with large drones forced all flights to be cancelled on Thursday. These devices then started to appear from 2019 in significant places, jammers.
  23. Martin beat me to it, But you are right to ? ESCs and connections Basically, a correctly connected/ soldered motor, does not decide itself to run or not. You know the ESC provides power via the position of rotation to each magnet, becoming the order to advance to the next and so on. You are both spot on. Establish the 3 leads have continuity, and the ESCs in my case, play a tune. You are right too about overvoltage. If the ESC detects " too much " anything, it shuts down. I usually test this with a pack below 100% charge, just not fresh off the charger.
