  1. I used to make a hole through the length of veneered foam wings by dropping a length of heavy gauge piano wire through having first heated the end of the wire to a red glow. Easy to make a guide with a plank of wood and some eyelets screwed in. NOTE - make sure the heated piano wire end can drop out and doesn't stay inside of the wing 😁. Dick
  2. Is it this one? A cheap clone with limited range :- "11. Remote control distance (no interference): 200m" Dick
  3. Actually, taped and glued is quite common on some high performance gliders - 1.6kg and 150mph+ BUT you have to do it properly, and that would preferably be glued to both wing skins. Dick
  4. The screen on my laptop looks different to Martin's screen shot, so just in case it helps, this is where the language setting is on mine in Firefox. Dick
  5. Most of the adverts I can find for that servo give a voltage range of 4.8 - 6v. One said 4.8 - 7.4v. Most HV servos work OK on a 5v supply, but with lower torque as you say. I don’t think the Aeromaster needs high torque, so at that price its worth a try. Dick
  6. For many years I flew a Sebart Pitts Python 50E which is very similar in size and setup to your Beast. During the time I flew it I experimented with all sorts of aileron setups and mixing:- a) all 4 could be moved down like flaps b) all 4 could be moved - top wing ailerons up, bottom wing ailerons down, (a bit like crow braking on a glider) c) all 4 could be moved - top wing ailerons down, bottom wing ailerons up (reverse of b)) d) coupled elevator and flaps e) with and without differential Apart from having a bit of fun experimenting none of the above offered anything worthwhile so I have to say that I flew it 99.9% of the time in a plain setup of "no differential and all 4 ailerons moving just as ailerons with the same throws". I am sure your Beast should be the same. I was rather sad when, after 8 years of regular use, I lost the Pitts to a spar breakage in flight. Dick
  7. There is a problem with GPS if you have fast planes that also turn tightly as it seems that over a certain level of calculated G the GPS system assumes the latest position is an error and substitutes an interpolated position based on the last "good" track. Phil Green referred to this earlier. I did some experiments with GPS on my F5B planes back in 2016/17 and abandoned the idea as the results were useless. F5B fly up and down a 150m course at high speeds with very tight turns at each end of probably around 10G+. The GPS system was rejecting the latest positions during the turns and substituting assumed positions based on the previous track on the straighter bits. After a few more readings confirmed it really was now heading in the opposite direction it jumped to catch up - by which time I was beginning the next turn πŸ™ƒ. The attached image shows the result. The yellow line in the middle represents the 150m course I was flying, and as you can see the GPS trace shows I appeared to be overshooting by about 300m in both directions. As a bonus the recorded max speeds were in excess of 300Kph πŸ˜€. The GPS sensors in use were the SM GPS Logger or a home built one based in this article https://www.rc-thoughts.com/jeti-gps-sensor/ GPS works fine on my slower gliders for GPS Triangle racing where I use the RC Electronics system.

  8. As leccyflyer says, contacting Overlander would be a good idea. Failing that, a set of scales would give you the weight and then you could safely operate it at the good old rule of thumb of 3 watts per gm of weight. Looking at similar types of motor my guess is that it would weigh a bit over 100gms so you could run it at 300 to 400 watts. It appears to be 1600kv so would want to run at about 13,000 to 14,000 rpm on 3s - say an 8x6 or 9x6 prop. No guarantees of course, but that is where I would start in the absence of anything available from Overlander. Dick
  9. Is it this one? Any other information you can give? e.g. can dimensions, weight, any text printed on it? Dick
  10. Having witnessed several identity failures and other confusions in the medical world in the last year, that is almost "not funny" πŸ˜€. On the other hand 🀣 Dick
  11. Interesting. Speed seemed normal to me Sunday evening! Dick
  12. IC props usually have thicker blades and are heavier to cope with the power pulses of the IC motor. E props don’t have that problem so are made thinner and lighter for a reason. You can bend a shaft with an e prop (done it!) which is why prop savers were invented, but I only use IC props on suitable motors so have never bent a shaft with one. Dick
  13. R&G in Germany provide a lot of information on their resins, and also sell different hardeners with different speeds for the same resin. Worth a look just for all the information. https://www.r-g.de/en/list/Resins/Epoxy-resin/Epoxy-resin-L---Hardeners--laminating-resin- Dick
  14. No, IC props are fine on electrics and I often use them as they don't break so easily. They are probably just a bit less efficient. You can't use e props on IC though. Dick
