Great video. Brilliant idea with the diodes, and fantastic flying. The plus side of the brownout was it demonstrated the airframe can survive a pretty solid lawn dart.
Thanks Martin - you're flying skills still blow my mind, even after watching you for years - you inspire my friend - - appreciate the info reference the "diode" trick too.
You need to do more videos like this Martin. They are extremely helpful and provide tremendous value to the hobby and us!! You gotta come up and fly at the club sometime. The guys from Club Icaro were over this weekend and we had a blast!!
We the same Martin, but all grounded. So frustrated that I cannot fly. Apparently we should be aloud as 6 people on the 8th of April, so hoping I will get that feeling soon 👍🏻
thank you SO MUCH for the tips/research! Now this is clearly the ultimate foamie setup, any smallest step above that, and we're back in fragile-balsa-land
OK I got the servos and I got the motor The motor comes with a speed controller but it looks like you change the speed controller and added a bec ?. I Also need to know what diode she used is there any way I could get a link to these items also not sure what battery you're running I sent another message rose wondering where you positioned everything I know that's a pilot's preference in CG and stuff I would love to have the complete set up if I could I appreciate you very much
Try the new Turnigy Plush - 32 20A with 4A BEC - good bit smaller too and 5g lighter (although 2mm thicker :-) Good to get out flying again - and with just a light jacket - nice :-))
Was just about to maiden mine with1.2A servos. Yikes! I want to use an external bec. What exactly is the diode you use. Make, model, part number etc. Would help greatly. Thanks.
I used Shottky Diodes, 10A 45v. anything around that spec will work, the specific version I used: BOJACK diodos Schottky 10SQ045 (10A 45V) axiales 10SQ045 (10 amps 45 voltios) para diodos de protección de reflujo del panel solar (paquete de 20 pie
Had a similar problem on my Yak55 foamie last week. Plane just fell out of the sky. Thought battery had died, then thought ESC was shot. Turned out the aileron servo had failed and was drawing more current than the ESC could provide,
Had similar myself last year, radio shouted out a receiver voltage warning high up in the sky, so I started bringing it down, then about 9' off the ground I lost all control and the foamie plopped onto the ground. Couldn't see an obvious fault but it gave voltage warnings as soon as I connected a fresh pack, and those cleared up when I unplugged all the servos. First time I'd seen telemetry both save a plane, and help with diagnosing the root cause. Converted me to wanting it in all my planes for sure!
Hi Martin. Question. Your external BEC is switched to 6V. ( you switched it from 5V to 6V for faster servo time, I saw in video)I have the same Blue colored Hobbywing BEC for my model. What voltage has your controller BEC? Probably it's 5V. Is it OK ? With 5V controller BEC power servo will be less faster.
Hi Tigran, thanks to the Diodes, all that happens is they would run at 6v as long as that Bec has power left and would drop to 5v during extreme power consumptions. That said, I dropped the voltage back down, so the torque and speed os always the same, as all we gaining the higher output from the Bec (from memory it was 5A at 5v as opposed to 3A at 6v)
I have ordered one of these with the electric package I’m hoping to improve my aerobatics with this model as one day I’d like to get a Pilot RC model.. just a question when you built this model what glue do you recommend to use for putting the carbon spars and in general glueing it together with also I seen you spray something on the frame what is that ? Thank you for your help advice very much appreciated
You will love it. Just use normal cyano (superglue) and the spay is cyano activator also known as kicker. Basically makes the superglue set instantly, so no waiting and no dribbles
Thank you for your videos. :-) PLEASE CONSIDER THIS ADVICE: there's no reason to use diodes, only drawbacks (unwanted voltage drop , unnecessary weight increase, unequal power consumption between the ESC and the UBEC...). You can simply use the UBEC to power the two aileron servomotors ONLY. Cut the 2 pwr cables of the aileron servomotors and connect them directly to the UBEC pwr cable. Do not connect them to the receiver! That way the ESC will power the receiver + the rudder servomotor + the elevator servomotor. And the UBEC will power the 2 aileron servos. With my solution you don't waste any power. You don't waste your money. And your problem is solved since each power supply (ESC + UBEC) operates within its own regular power range.
I'm having the same issue with a yak I'm building. It's got 6 servos and it shuts down the reciever I'm using a 30 amp esc well actually 2 because it's a twin. Here's the question I've been told to disconnect 1of the bec with a twin. Could I actually use both bec to solve the issue or would that burn something up. 🤔
Martin. I have this plane still in the box. Can you tell me what size prop and what manufacturer like APC E-prop you recommend? Also I need good reliable metal gear servos. I know your running maxed out servos. I just need good quality metal gear 9gram servos to put in this plane. I don't need the speed or precision you require. I really would appreciate a recommendation on servos. It seems there is a lot of "Junk" out there. I want acceptable speed for a novice 3D flyer with excellent build quality and longevity. Thanks so much for your help with the prop and servos. I will get the T-motor your using! Excellent video and flying as always! and great diode trick I will put that in my memory bank!
Hey Martin, I always enjoy your videos! I've been sport flying for over 10 years and set out to learn 3D around 6 months ago (in part inspired by your videos), it's been going well, but I still have some difficulty not giving the wrong rudder input while sustaining inverted flight. No trouble with roll or pitch, and I can knife edge and even rolling harrier ok as well as hover and torque roll. But when I try staying in an inverted harrier I almost always mix it up and lose coordination so I just end up having to roll out. Any advice? Thanks for any tips you might have, and for all you contribute to the hobby!
Hi mate, this is going to sound really strange... but try to lean forward, backwards or sideways, and turn your head a little, kind of having your face at an angle that it would be looking at the canopy of the model if it where in a hover next to you. This helps try and visualize the model in a “hover” position and if you can do that, left is always left... right right... 😄
There’s a 0.6V drop through the diode, so only 4,4V to the servos. I have used other workaround, but you’ll land with an unbalanced lipo. Take 2S power from the balance lead directly to the servos, number 1 and 2 cell, very importante to keep ground common!!! Decent digital servos will take the 8.4V no problem.
Schottky Diodes have a much smaller drop, I lost about 0,1v which I found to be very acceptable for the solution. Not all servos will hold HV, especially in this size. These ones are only rated to 6v and will kick the pants off every other HV servo I have tried...
@@MartinPickering-PickeringRC Yup, the DS95i has a reputation of being the big daddy of small heli tail servos. If you have a tail problem with a heli, or a bobble you can't get rid of, no matter how carefully you go over the mechanics, or how much fine tuning effort you put into the FBL, fit a DS95i and watch all your problems disappear. Insane torque, centering, and speed means that servo literally brute forces tails into behaving. I've seen a lot of people over the years left amazed by how well they work.
Would be easier to run a HV servo set like the HV93, and just power the electronics from 2 cells of the battery pack. Sure, those cells will drain a little faster than the others, but 4A is nothing to them, and a good charger will easily balance them out as you charge. Some receivers will also then let you monitor battery voltage, giving you flight pack telemetry without needing to add mAh or voltage sensors.
@@MartinPickering-PickeringRC No, I don't think any have per cell, but overall voltage is fine. I run a HV receiver on a F3P model with a little logic in the radio to have it use the average voltage readout over a period of a few seconds so that it doesn't alarm every time I pump the throttle. It's amazingly accurate, I can land consistently with the packs at 3.75V per cell. And if you were powering the electronics straight off 2 cells, that would give you telemetry through the receiver of the 2 cells with the lowest voltage. I just wish there were more HV servos out there, it's a lovely neat solution, way better than flying to a timer if you have a varied flying style :-)
Makes no sense that ur field is closed, contact your local city hall and talk with them, that’s what I did and turns out we were able to be open and fly
@@MartinPickering-PickeringRC Martin! I was having the same problem, I found these speed controllers on getfpv.com www.getfpv.com/v-good-rc-32-bit-30a-2-4s-brushless-esc-for-rc-airplane.html they has a 4A SBEC and the 40a ESC has a 5A SBEC! Also vgood esc's are buttery smooth.
i cant see any reason at all to do this on such a small bird.. i use dual BECs on some of my larger scale planes like my 102" slick where the power requirements are much more needed.. but this seems like unnecessary overkill on such a tiny plane..
Great flying!! Hi Martin, can you do a video on your setup with the 3D foamy's from your radio settings?
