Good evening Gentlemen, I hope everyone is well. I need some advise please, I have just fitted a new E-flight park 450 brushless outrunner to a new model, it is connected to a HiModel Fly series 25A ESC. When I connect the battery, Flight Power EVO 25 1800mAh 3s 11.1 V LiPo, the beeps do their thing, I have flight controls, but the when I push the throttle forward, the motor trys to start, but just stutters for o whils (in both directions) then stops. I try again and the same thing happens, then it might run up to full power and all is well, throttle back, allow the motor to stop, and it just stutters again.  The motor instructions suggest a 20A ESC, and later on says a sensorless brushless speed controller. The ESC I have is a brushless one, so what might be wrong? Any suggestions welcome, Thanks in advance, Dave

Believe it or not, I got this model to practice flying a bit closer in and lower than before, just didn't intend to get as low as I actually managed

I've been flying for a year this month Bruce, and this is my first crash, as Ive been told, "if you don't want to risk a crash, don't fly". It was a silly error and I will learn from it, lets hope the weather will be good next weekend so we can have another fix.  Dave

Well chaps, just to close this thread off, I got the model ready, changed the gear to spektrum stuff, range checked all OK, took off  fought with it for a very short flight and crashed writing the model off. Guess what, I didn't reverse the aileron servo so they were working in the wrong direction,Doh, what a complete idiot. did I feel stupid? -  yes, had I made a mental note to reverse the servo prior to first flight? - yes did I forget ? - yes Do I always check the engine and flying controls just before take off ? - yes, every other time, did I do it this time?  - no obviously not, Why? Thats the million doller question isn't it, but I don't need a bigger reminder than the one I got yesterday . So anyway, it turned out that the biggest glitch was caused by the guy twiddling the sticks, , you live and learn etc.................................... 

Ah, experience comes into play. The model is a 39" span low wing aerobatic job, I bought it with no assembly instructions and put it together with what I had at hand. I fitted mini servos where micro would have been better, one consequence was that the aeileron servo protrudes from its location in the a little further than is ldeal, the other servos are also taller than ideal. I had it fit a mount for the battery etc and all this seemed to cut down on usable space. Having actually got the model to a flying condition and correcting the c of g etc the battery is now much further forward than I had originally  installed it, so freeing up space.  Another issue was the model is narrower than the length or the aeirials on the spekky rx and I was not sure that they would be ok touching the airframe sides, bearing in mind they sit in opposite directions I could put the secondary (smaller one) crossways? Anyway, this led me to fit a standard graupner 35Mhz rx that I had it hand, to be fair it is actuall bigger than the Spekky one, but it is a single assembly and seemed the wat to go at the time! Interestingly a mate brought an electric model along yesterday that has suffered extreme glitching, we changed his rx and tried mine in its place and his problems were immediatly solved, with his model flying safely for the first time. Strange eh!  Dave 

Well I flew yesterday, (first electric flight), all was good apart from glitching, not suffered this before but landed safely. I changed the position of the rx and routing of the aerial, and it was a little better but not perfect. I think I will fit a specktrum rx instead of the 35 Mhz one and see if that improves things. I had originally planned to fit this but was short of space, but in having to move the battery for the CofG etc I think it should fit ok now. Unless there are any other suggestions?  Dave

Tim, Nicholas, thanks for your response to my problem. I have no sorted my "school boy" error, I had plugged the ESC into the battery slot instead of the throttle,  Doh!!! Anyway, I will noe sort the CofG out and hopefully fly electric on Sunday (as the weather is supposed to be better than the rain and low cloud this morning). Once again, thanks Gentlemen, I appreciate the help, Dave

Well, I've charged the battery, pluged everyting in and there is no response from the motor, no beeping , movement , nothing. I'm at a loss as to what to try next. Apart from a shockie this is my first electric model and I really want it to work. I'm sure I must be missing somthing really simple. Dave

Tim, thanks for  this, I get the battery on charge and see what happens then, Dave

I tried changing the throttle channel which made no difference. Then I plugged the ESC direct into the rx, rather than through the switch that I have fitted. I got a series of beeps which was encouraging, real motor movement other than a half turn when the stick was pushed. I susspect that the battery needs charging so will do that next. Is it likely that a low battery will give flying controls but no motor? I Think I have read somewhere that this is a kind of failsafe.  Dave

Cheers Tim, I will go and check throttle channel, I am getting no response at all. Dave

I have plunged into the electric world, and have a slight problem. My motor has a red / yellow / black wire, and the ESC has three yellow wires. Which way are they supposed to connect up? I have tried various combinations but with no joy, please help! (All other controls work ok) Thanks, Dave

Hi Frank, I joined a local club and learn and fly with. I arranged my insurance through the club with what I think is the the German equivilent of the BMFA, called "Deutscher Modellflieger Verband e.V."There is a link to them from the BMFA web site (international associations). As for the regs, I only know what the club do, but as with most things here there are usually controlls in place. I know an guy who flys his heli in local fields close to his home, and I have flown (well crashed really) a shockie on my local school football pitches, but I shouldn't think a ic model will be appreciated in a public park, (especially during "quiet time"). I would say join a club, they are likley to be really friendly, my German is rubbish it hasn't stopped me being welcomed. 2.4Ghz is allowed here, I use Spektrum, but I am the only one with it in the club. If you do join a club, I would wait to see what gear they use before buying yours, Graupner/JR is very common, and they seem to fly mode one,  If you are learning then you might want something compatable for buddy lead training. I used the Spektrum as a student trans linked to a 35 Mhz Graupner master trans with no problems, literally plug in and fly. This might not be the easiest  way to get into the hobby compared with diong it in the UK but is well worth the effort, Good luck, Dave

Yes please

yes please, it looks great

Frank, If the  "small lugs"  on the back plate you mean, are the ones I think you mean, they ensure that the prop is lined up correctly to exit the spinner, when it is tightened up against them. I hope this makes sense. Dave

JU 87 Stuka DH Mosquito Me 109 All three are great looking aircraft in threir own way.

Jim, tra la la, I,m singing the here we go again song with you..........................

Yes please, Eventually my luck must change.................................

Maurice, I know you mention a low wing model, but consider a great planes big stick. It is a great follow on / 2nd model, aerobatic, stable and well built. Mine has an OS .46 AX fitted which is a great engine with plenty of power. (Mind you, David's Acrowot looks the business!) Dave

I've just got in after the most glorious day of the year so far, I've been flying my new Big Stick (great planes) and it so good after my trainers. With hardly a breath of wind clear blue skys and bright sunshine, what more can you ask for. All the best Dave

Yes please.  Dave

Thanks Bruce, it looks right and obviously works. I holed that area so have to repair it and thought I would take the oppertunity to beef it up and make the conversion. All the best, Dave

Bruce, how far back from the nose have you fixed the undercarrage. I want to convert my tutor 40  the same way, these trainers are all so similar it will give me a good starting point.  Cheers Dave

Here we go again, I'm in (please).
