Adrian Smith 1 Posted October 14, 2017 Author Share Posted October 14, 2017 Looking more like the complete thing with the rest of the bits put on. I will make sure all screws and nuts are flight tight next and generally check things over. The prop is JXF wooden one 20X10E, although I have the option of going a little bit over to 21x12E or a little bit under at 19x10E with the 12S set up.

Gary Vinten 1 Posted October 16, 2017 Share Posted October 16, 2017 Hi Adrian What motor spec are you using and esc are you using Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted October 16, 2017 Author Share Posted October 16, 2017 Hi Gary, the motor is :- **LINK** I have another of these motors on my Bondaero MXS 78" MX2 170E using a 20x10E wooden prop and have found it to be an excellent performer. For this Extreme Flight 83" MXS I am using a 120Amp ESC OPTO version from 4-Max reference PP-TESC 120HVAU While the voltage regulator or UBEC, which is wired into the Lipo battery power leads, is a 4-Max 20AMP regulated down to 6volt. This is all connected up with a hefty anti-spark connector. Hope that helps you. Needless to say I am looking forward to the maiden! Quote Link to comment Share on other sites More sharing options...

Adrian Smith 1 Posted October 16, 2017 Author Share Posted October 16, 2017 Yes John, I agree. Hope she flies as good as she looks. I must say as an IC'er I am getting quite excited about electric flight. There, I never thought I would say that! Quote Link to comment Share on other sites More sharing options...

Adrian Smith 1 Posted October 18, 2017 Author Share Posted October 18, 2017 Based on your question, were thinking of undertaking model of this size,Gary? The suspense is killing me! Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted October 26, 2017 Author Share Posted October 26, 2017 Having been doubtful last night about the weather, this morning turned out to ideal maiden flight weather. Nothing else for it, but to get it done and disappeared down the field at the crack of dawn (well 8.30am anyway.) Not much wind about...... All nicely strapped in and ready for pre-flight checks and range check. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted October 26, 2017 Author Share Posted October 26, 2017 All lined up ready to go. Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted October 26, 2017 Author Share Posted October 26, 2017 The flight was completely without stress. All I had to do was give her four clicks of right aileron ( may be something to do with the racing tip alignment), but you can see it from the above photo it is not quite there. CoG seemed about right at the mid-point range between 5 1/4-6 1/4". Knife edge pretty clean with no inputs needed other than a tad of rudder. Loops and rolls pretty clean and the stall turn was absolutely precise and spot on. Lastly, I tried a couple of upright flat spins from height which need a bit of work on, but good enough for the first flights. Back on the ground safe. The debrief is short and to the point. Landings are a peach and touch down is as light as feather. Much, much better than I can achieve with my petrols so I am pleased with that. Power is provided by 2 x 4500 mAh TopFuel 6S Lipos wired in series and 20x10E wooden prop. Duration was 8 minutes which was as far as I was prepared to go, but there seemed a lot more power left at the end. Yipee ..............

Rich too Posted October 26, 2017 Share Posted October 26, 2017 Superb Adrian, well done! I'm jealous of your patch, you must get ALOT of exercise mowing that Quote Link to comment Share on other sites More sharing options...
Adrian Smith 1 Posted October 26, 2017 Author Share Posted October 26, 2017 Thanks gents, looking forward to more fun in future. I have use of a ride-on mower for the grass, Rich. Takes and hour and half to do on a good day, but well worth it to keep it short for the electrics. The I/C models can cope with it a bit longer of course.
