William Macleod Posted June 16 Share Posted June 16 Hi, Just acquired, the supposed prototype, Mini Jet Provost at the BMFA swapmeet today. Stupidly, forgot to ask any questions Lovely Model but its fitted with a stabiliser. Never had one of these. I have bound the rec to my spektrum nx6 and all works fine. However having connected the battery and placed the Model level I switched on the stabiliser and after a short time all seems well. If I move the Model laterally the ailerons move to correct the Model ,if upside down it applies full aileron. Elevator also works in the correct sense. If I state the two position "a" switch I can stop the roll stab function but not the pitch function. So the question are .... .1. Am I arming the system correctly? 2. Should I try to allocate a 3 position switch to the isolate function? 3. What make/model is the stab system? Thanks...hope to maiden it this week Bill Quote Link to comment Share on other sites More sharing options...
John Lee Posted June 16 Share Posted June 16 It's the 'Vector' gyro, as fitted to many of the Arrows models 50mm EDF series. In the Arrows models they come pre-programmed & are not adjustable, I've not come across programmable versions but they may be available. I've not seen it with an external switch, the switching on mine is via a 3 position switch to spare channel on the Rx that goes into the input 'BS' Here's a scan of the instructions as supplied by Arrows: 20240616_Vector.pdf Quote Link to comment Share on other sites More sharing options...
John Lee Posted June 16 Share Posted June 16 As fitted to my Hawk & Avanti. Great little gyro, set it to 'stability mode' for the launch & it guarantees that it will get away with a 100% success, then turn off or use 'Dynamic' as is your preference.

William Macleod Posted June 16 Author Share Posted June 16 (edited) Many thanks John. Managed to get it to work on both channels and isolate by a switch on the TX. Question is do I test fly with it on or off? Just seen your second post. Bill Edited June 16 by William Macleod Quote Link to comment Share on other sites More sharing options...
William Macleod Posted June 16 Author Share Posted June 16 I have a spektrum TX and rx...any idea which channel on the rc to be able to use a 3 position switch? Quote Link to comment Share on other sites More sharing options...

leccyflyer Posted June 17 Share Posted June 17 Good luck with the maiden flight Bill - hope that you get a better result than my half a dozen failed attempts at flight. My TN Jet Provost is now a retired static display model hanging from the ceiling. 🙂 Quote Link to comment Share on other sites More sharing options...
William Macleod Posted June 17 Author Share Posted June 17 Well flight 1..gust stab only my handlaunch Just descended into the grass. Flt 2 stab fully on, handlaunch went great flew quite fast tried the other stab positions not very good so left at full stab. Forgot with edf not to get slow round finals and just missed the ground at full up elevator. Tried the same thing but with more power much better. Two further flights using 3s 1500 cells all good. Lived to flight another day. Bill 5 Quote Link to comment Share on other sites More sharing options...

William Macleod Posted June 17 Author Share Posted June 17 Yes. I was going to check my logbook for 1970/71 to see which Mk 5's I flew during training. Happy days 4 Quote Link to comment Share on other sites More sharing options...
