Does anyone have any info on a Jamara Xenon 25-40 amp esc, ser no 081511, which came fitted to a used glider that I purchased, it seems to work ok but I cant find any setting instructions anywhere on the web. I would be very thankful if any one out there has any set up instructions. Thanks in advance Peter G

New Question for Malcolm, using the 14SG transmitter, R700SB receiver, and SBS 02A telemetry sensor for altitude, set up on FASSTest 14ch. All seems ok green lights overall, but on tx screen it does not display actual meters, I can only see a dotted line, any ideas or is the sensor defect, the same setup was placed in another glider and did at that time show a reading, although it was only mounted and not flown. TX and RX were re linked and works ok, just cant get any reading from the sensor. Any ideas please

Sorry, that should have read Malcolm, just another thought, should the tx and rx be linked with the sbs sensor connected or not?

Thanks for replies, but as I said, that was only theoretical, actual situation is, I have a model that is not used but has the receiver mounted and programed into transmitter, if I now put this receiver into a new model would I have to rebind it or can I just program a new model in the transmitter?

Probably a question for Malcom but anyone else might know. T14SG and R617FS receivers. I have more models as receivers at the moment and to save money can I swap receivers from one model to another, and then use another model setup in the transmitter. Is the set up locked in the transmitter or the receiver, Do I have to bind the receiver for each model or is this a one time operation. As a theoretical example, if I have only 1 receiver and 4 models and 4 models programed in the transmitter can I swap the receiver from one model to the other without problems. Thanks Peter

Why is it so hard to post a reply here. Logging in for the umpteenth time, password not recognized , email address is used by another user. So last try today. Thanks Eric, I did eventually find the article in the archives and makes sense, so in the time before we can fly here again I can try some setting up on the bench, with prop removed of course, so a bit of reading for me now it seems

Thank you Eric, but I have a problem there, due to the lockdown from last year, I did not recieve the may issue?, living in Germany, is it possible to read a digital version back issue here on the website, I tried but could not find anything. Or maybe someone could attach a photo of said article. ?hmm, just had a rush of something to the brain, maybe I got a digital copy instead, must look on my pc, hopefully it was saved.

Thanks for replies, tx is futaba 14sg. I too prefer throttle on the stick, so would it be possible to put crow braking on a switch, slider of rotary control?

Hello all, I have recently obtained a used multiplex heron and on looking at what other people have their control surfaces set too, it looks very complicated. Now out of practice with the lockdown here too, my question is, could I set up my heron using flaps as in a normal plane setup to start with, to get the hang of flying this for the first few times, or is it essential that I use crow etc set up. I would be flying from a flat field only, not slope soaring. Do not really want to make things too complicated for the first few flights. Thanks in advance for any advice. Peter.

Thank you Flynn for your reply, as you say CAD is not easy, but have since found FreeCAD which goes from design to CNC all in one set of software, and there are loads of tutorials on the web so I will give it a try, but also look into your suggestions too

Hello all you experts out there, recently been given a small CNC router but seems I need CAD and CAM software, looking on the internet it all seems expensive and complicated, don't really want to splash out at this stage but would like to try and learn first. Can anyone suggest any suitable freeware that is not too complicated to use so that I could give it a try. Not looking to make anything fancy at this stage but just thought it may come in handy if I need to cut something to make repairs (again) etc. Any suggestions or advice would be most welcome Thanks, and stay healthy, Peter Goldsmith

Thanks for your reply Malcolm, will try it out later. Peter

Hello Malcolm, I have a question for you, I have a used piper cub and the recomended throws for control surfaces are around 15 mm, I have the links on the closest to the middle on the servos and the longest on the horns to give the smallest amount of movement, but it is still way to much from the recomended settings, can I set this up on the transmitter using dual rate, or am I making more problems for myself, your advice will be very helpful, thank you in advance. I do have your book but cant seem to fathom out the best solution.

Hello all again, seems I have the CofG cracked with my S Bach, seems to fly now with no problems. The seller of the model said he had flown with a 4s 2600 mah batterie, I bought a couple of robbe EVO lipos but seem to have a short flying time of around 5 minutes even though I am only using about half throttle until I get used to the model, I was thinking that I need a larger mah batterie, Any suggestions for good lipos , Thanks Peter.

OK thanks again to for all the replies, will try out at the next flying oppertunity

Hello people, just a question to help with my sebart sebach 342. Having purchased the model second hand and done a couple of minor repairs, actually got to fly it for the first time last weekend, (still in one piece so obviously did something right) After checking the CofG with ballancer and a vannessa rig I had two different CofG points so decided to set up somewhere between the two, only talking about a centimeter difference. Anyway my question is, the plane flies ok, at about half throttle flies nice and level, give gas and it climbs, so far so good, now when I fly straight and level and cut the throttle to zero, the plane begins to dip, down, picks up speed and then climbs, slows again and drops and so on, its not wild just like a mild roller coaster. Would this indicate that it is still a little nose heavy, tail heavy or just about right. Many thanks for any advice . Peter

Thanks Colin, much appreciated

Hi everyone, been a while now and getting on ok with flying, (and repairing) have not yet flown the Angel but been practicing with a smaller version. So my question, just bought a used sebart sebach 342, from a guy at a model flea market/swap meet, just needs a bit of polishing to make it look good. The guy told me he flew using 4s 2600 lipo, I was just wondering as after looking on the internet it seems the original spec is for a 3s, however I think I have a bigger motor in mine. the setup is as follows, Planet-Hobby Joker 4250-6 840KV motor, Eflite 60 Amp Pro SB, esc driving a 13x6.5 prop. before I make a twit of myself at the field, (too cold and snowing at the moment) does anyone have any thoughts on this setup re amps watts etc etc. Happy new year From Germany Peter

Ok, thanks all,

Hello all, another probably easy question for you, I have been flying my second hand cheapy sebart lookalike with limited success (repaired and still flies) Original prop was 12x6 and I fly with a 12x5, my question is what is the difference in performance between the two props using the same motor, battery etc, would the 12x6 give more speed for the same throttle position or would it just load the motor more and draw more amps and reduce the speed of the motor. This question is just so I can better understand the difference between thrust and torque. I am not interested in doing fancy aerobatics at the moment just simple flying and safe landings. Thanks in advance for any advice.

Thanks Denis, that makes sense, Ill give that a try, so would I be right to use port or channel 1 on the receiver so that then gives power supply and control over the motor speed?

Hi all again, the above problem I have sorted, now for something different. Been trying to set up a futaba T14 transmitter with frsky TFR8SB receiver, binding has worked but which port should the connection from the esc plug into, tried using the same method as for spektrum, but the motor just keeps playing music, (beeping) and how do I identify which channel does what between transmitter and receiver. Seems the futaba is a lot more complicated than the spektrum, but I am told it is much more reliable, Thanks in advance for any help Peter

Thank you again for your replies, but like I said it was a silly question, I have since found out that the control sticks on the actual transmitter were out of calibration, recalibrated and now is all is ok. I think I will now have to go and check the settings for my other models as they are probably now not in the right position. Learning by doing I think its called. Ho Hum
