  1. I usually end up testing mine just after I attempt to take off.
  2. This is is the wiring diagram for the Black Devil 172. Its nothing special so you would think this would be a problem on all motors.
  3. Not quite sure how this would have any effect on the kill switch. The kill switch just grounds the low tension side of the coil. The RF generated by the pulse going up the tacho pic up wire running alongside the kill wire will do nothing. In fact the coil side of the kill switch already has a pulse on it, which I have verified with a scope and I use this pulse to calculate the rpm on my Paramotor Engine Monitor I'm working on. Is the Tiny Tach powered from the motor rather than an internal battery? If so there could be an issue there.
  4. There is a fair bit to think about when swapping engines in frames but the issues are not unsurpassable you just have to think it through. I'm not sure if it has been mentioned but this video series will give you things to think about. It was a great help when I was working on putting the Moster MY19 in my Airconception frame. It worked really out well when I did mine. The only issue I had was I moved the mass just a little to close to my back it was nothing and extra prop spacer didn't fix to give me an extra 10mm hoop clearance. I'm always will to help if you need it.
  5. The offroad version is the one they suggest. Something to do with flashpoint. I thought the different bottles was just a selling tactic but apparently it's not.
  6. Great news. I watched loads of videos on last year's event, I will certainly be there.
  7. I use the outside of a biro pen. Push the cord up the inside at the fat end then use it like a needle.
  8. If any of you guys want to feed the audio from your 2m radio into your go-pro audio in, this circuit works. I spent the last two days getting the values right so the audio from your mic and the audio from the radio is about the same level. Using Baofeng radios and the normal Go-pro remote microphone.
  9. Just my 2 cents but as Steelmesh if your current draw will allow I would always go for a LiFe over a LiPo. Yes they do have a lower nominal voltage but they are a much more stable chemistry making them a lot more forgiving for both charge and discharge. Also they have a much lower self discharge rate meaning you don't have to put them to storage voltage if you want to store you kit up for more than a month or two.
  10. That's what I'm trying to figure out. I'm building a "safestart" style system but for a sensible price hopfully. I have now set up dip switches so you can select a kill time between 500ms and 4000ms in 500ms incriments.
  11. Hi folks. Any of you guys that fly motors without clucthes, how long do you think you have to hold the kill button down before the motor is stopped. I have no way of knowing as my moster is the clutched version. I'm working on a project and this would be helpful. Cheers.
  12. Hi guys. Is anyone based near Hepworth (Bury St.Edmunds) way and free to spend an hour or so with me tonight or tomorrow morning? I have just finished putting together my AC130 / Moster and would like a sanity check and help setting up the new harness properly. Tea and biscuits will be provided. Cheers Adam.
  13. Maybe some of the guys here will know somewhere. I can only testify to the quality of Simon's training at paramotortraining.com but thats possibly a little far to travel.
  14. Interesting article but from reading it the chamber will go between the exhaust port and the expansion chamber. The problem I can see with this is it will severely hinder effectiveness of the expansion pipe. From my book leanings the expansion pipe is designed to produce the high gas velocity/low presure entering the widest part which in turn creates high backpressure front as the pipe narrows again to push some of the unburnt charge back into the cylinder. If there is a large void between the two what would stop working surely? Ref: Tuning for speed. Phil Irvine (1960) Great book for getting right back to basics. When I was racing 2 strokes and building my own pipes it was my reference as it contains all the calculations needed. https://www.abebooks.co.uk/book-search/title/tuning-for-speed/author/irving/pics/
  15. Best thing to do before you even look at kit is get some training. Not only will you see if this new hobby is for you but also you will learn a lot from the people you meet and they will be able to guide you in your purchases. I'm sure some of the guys from around here will be able to suggest a good local training centre. Where are you based?
