Maiden Xfly Twin 50mm EDF A10 - Disaster 16 July 2022

[@airhammer6203]

Oh, wow, here comes the boom!! I wouldn't want that to happen to anyone, Martyn. I noticed the strap immediately, hoping, maybe off camera. I'd have to get a fuselage just to show it what for, as long as the motor/esc's are good. The aileron separation, I REALLY hope not. I was just about to pull one out of the box and build it (it's been waiting awhile). My condolences to you. AirHammer out!!

[@FlankerTanker]

Hi AirHammer - cheers - appreciate your comment , I bet a lot of people watch this video will spot that and more than a few will scream out The Strap.....You forgot the Strap!!!!! - 🤣😅🤣😂, I guess we will never really know about the Aileron - No Question about the Battery !!! - 100% my fault - did not repair it - scrapped after removing the good parts - Stay safe AirHammer - Martyn OUT.....

[@ModelAV8RChannel]

Well that disclaimer was hilarious! On the crash - I've seen foam control surfaces come off in a crash, but it could have come lose in flight. I've seen that as well, but only with a well used airplane...not a new one. I would say that is likely more than a battery shift only because the battery would have gone forward. Nose heavy planes...even severely nose heavy planes will fly. They will fly bad, but they will fly. I think if the battery was it you'd have landed. Hate it crashed my friend. That sucks. Stay well buddy...

[@FlankerTanker]

Hi Adam - I found the disclaimer to be very funny indeed , so thought now is the chance to use it - LOL, Happy you liked it - as for the crash - well My fault - battery not strapped it, I think it had moved a little during the take off run and the A10 was a little sluggish - I was switching from low to high rates on a turn and I almost always lose Hight when I turn - I think this allowed the battery to slip to the nose - and I had no control at all - Aileron was also defiantly ripped of due to the Impact- still none of it matters now - the Lesson here for me is Strap in every time - even when checking CG, A10 scraped for parts, might get a Multiplex Twin Star and use the A10 power system for it... EDF Twin Star - until then I will crack open another box and Assemble what lies within - Cheers Adam - Stay well - Martyn

[@paullepine4765]

Disaster Martyn! I'll remember this when I finally get my Xfly A10! I would echo Gina - I've had Ailerons/flaps detach from the force of a nose dive, so that would leave......the battery? Better luck with your next maiden!

[@FlankerTanker]

It is a 101 mistake - not securing the battery - still I heard it said that every cloud has a silver lining - just got to find it in this - Good luck with the maiden of your Xfly A10 - what I will say is the short time it was flying it was OK.... Stay well Martyn

[@Bellairvideo]

Ohhhhhh Mr. F Tanker, what a shame. I recon the aileron was not glued in properly

[@Bellairvideo]

Just had a call from someone…,sorry. Yes u believe this is what has happened Martyn & not your fault. Keep strong & safe mate

[@FlankerTanker]

@@Bellairvideo Hi Noel - Kind words - but the more I look at it and think all about what happened I am now convinced that this was 100% my fault for not securing the battery in with the strap - its a silly mistake but cost me - On wards and Upwards as they say - thanks Stay well Martyn

[@Bellairvideo]

Will you try & repair it Martyn?

[@IansRCExploits]

Aww Martyn, Cheryl spotted the unsecured Velcro strap straight away!! I'm really sorry to see the damaged plane, as once sorted you would love the way it flies 😀👍

[@1tonyboat]

one of the most important things to check in my book especialy after swinging it around to do a C of G check.....we`ve all been there ....

[@FlankerTanker]

Hi Ian - Oh Yes - How silly was I - gutted - and all my own fault - Poor Cheryl, I do hope she was not traumatised knowing that something will go wrong - oH well Time to break out somthing new and assemble that ... Decided not to save the A10 - Cheers Ian/Cheryl - Stay safe and well - Martyn

[@sethgreenberg7725]

Mine did the same thing after a few weeks of usage

[@keithmoore5306]

OUCH!!! hard telling Martyn i think you might be right on the combo as the cause though the battery shifted and overstressed the hinge! although frankly i'm amazed those hinges hold up as well as they do being just foam!! you might want to add a collection tote to your field kit though! and maybe a cooler to mix saltwater in when you kill a battery and need to haul it home! that's the first time i've seen the insides of a lipo i always thought they were cylinder shaped and in a row because of how the ends are rounded not slab shaped and stacked!!

[@FlankerTanker]

Hi Keith - See even my channel can be educational LOL....😁😁🤣🤣🤣🤣, Not how I would like you to have seen the insides of A LIPO but what can I say ..LOL.... I ended up tipping everything out of my little metal case tool Kit and putting the Lipo in that to get it home , truth be told Keith I hope I don't have the need for a cooler and salt water for a few more years to come...... A10 scrapped for parts... Something new to be unboxed now......Stay well Keith - Martyn

[@keithmoore5306]

@@FlankerTanker although serious on the battery the cooler and bin was a bit of chain yanking!! and seriously for the life of me i don;t see how those foam hinges last one flight let alone for years!!

[@waynesrc1958]

Oh sorry to see that, the battery was not secure moved forward and she nosed in. Had a similar experience with my FW190 only the tray popped out making it tail heavy. I was lucky and able to land it with out damage. Enjoy your videos keep them coming. Wayne in Minnesota USA.🙂

[@FlankerTanker]

Hi Wayne - I your case it was a faulty Battery tray pleased to read that you saved it - in my case it was my Mistake - I know better ..!!! - I guess as it was the maiden , and I had no flying time invested in the A10 - I do not feel it is that much of a loss for me - strange I thought I would be more upset - but I am not - oh well - Lesson 101 - Secure the Battery , Learnt again the hard (well Expensive way) 🤣🤣🤣, Thanks for your comment - stay well .

[@sethgreenberg7725]

I believe it was the alerion detached not your fault

[@howiedenton2709]

Sad to see this happen to your A-10 Martyn, sorry. I also think the battery strap mistake is the most likely cause here. I definitely don’t think your left aileron detached prior to ground impact, just wouldn’t happen in flight unless it was heavily damaged and you’d have seen that damage during its build prior, but nose in to the ground it can easily happen. Did it myself just 3 days ago with my E-Flite 850mm Pitts, both top wing ailerons completely ripped clean off, top wing off too and rest of the plane generally obliterated, will have to get a new one, good plane, pilot error throwing it around in 12-15mph winds. I usually watch your videos on my iPad but threw this one up on my 55inch screen. Most likely the battery has shifted forward on the bumpy take off, you say yourself, “she only just got up” on the audio. Had the same problem with the E-Flite 70mm Viper which I replaced the stock hard nose gear on for a Castle RC sprung ‘upgrade’. Like you say, losses angle of attack on the main wing with all the nose bobbing when flying off grass. What I saw much clearer on the big screen was a very high bank angle on that fateful 2nd turn, she drops like a stone almost immediately (just before you annotated the footage with the white ring). I think with the forward battery plus high bank angle she dropped out on herself, classic RC tip stall. Can you remember what kind of throttle position you had at that turn? Maybe she would’ve survived that turn at 100% throttle, but likely overly forward battery position, high bank angle into turn, possible lack of throttle in the turn and she was on a hiding to nothing. They say a combination of 3 things going wrong in real life aviation situations results in a crash. You also mentioned she felt sluggish back at the bench, these videos are our version of the black box. Kinda pilot error but not really, ground crew f*@$ed you..!! You’ll never forget a battery strap again that’s for sure. Hope you get another one in the future and make it work, my plan with this model is to hand toss/belly land it.

[@SunriseRCAviator]

Huge bummer Martyn. It is such a nice plane so to see it severely damaged was not fun.

[@FlankerTanker]

Thank LAPEOS RC - all my own fault - that strap !!! - silly beginners mistake - I know better and it should not have happened Lesson learnt - A10 scrapped for parts, time to Assemble something new... Thanks for your comment - Stay well - Martyn

[@jonathanland2218]

Martyn I think it was the battery movement changing the C of G. I lost an aileron completely this morning on my Fantasista and with only one still attached I still landed safely. Sorry for you loss! Jon

[@FlankerTanker]

Hi Jon - I agree I think that I was the cause of that one - 4s Lipo on the Rampage . CG on the nose ....LOL...😁🤣🤣🤣, Jon Your flying skills are on a different "plane" to mine (no pun intended) - but I am Flying Skills 101 when competed to yours ,😀 I am not sure I could have saved an aircraft with a missing Aileron - Well done , Hope you get the Fantasista repaired soon , I know how much you like that one.... I have scrapped the A10 for parts and will see what I have in the Wearhouse 😅😅....

[@ltfadl1]

Oh no mate! Well as we all know crashing is inevitable, but sucks major donkey...... lol. Sorry about the loss, I'm sure there will come another. I want to purchase Xflys A10, but I have 2 UMX A10s one is in the box still and want to sale it, if I do then I'll pick this one up. Can't wait. I wish I could help your crash analysis, but for good measure I'll say possi lt a mix of both theories. I also crashed today 🙃 aileron servo stopped working. 😡 outcome is repairable but annoying

[@FlankerTanker]

Sorry about your crash - as you say in your comment it is inevitable at some time , but it feels just a bit worse when you know it was all your own fault - as I am sure it was all down to that Battery not being strapped in - - Oh well pleased to hear that you can repair your - for what it is worth the short time I was flying the A10 it seemed good ...... Stay well

[@dave1kearsey]

Hi Martyn, sorry about the loss of that plane. It's a nice model. I was wondering if the long roll out in the grass might have caused the battery movement. The plane would be bouncing a bit over the "bumpy" grass, and the springy front wheel might have increased the front bounce. The up and down bouncing could have jostled and lifted the battery above the 1cm lip you discussed...then the battery was free to slide forward. Just a thought.

[@FlankerTanker]

Hi Dave- Could well be, I do see your point (its a good one) - I am leaning more towards the Battery shift Idea rather than a damaged Hinge , as the cause - its a mute point anyway now , Scrapped the A10 for parts, Lesson learnt the hard way - time to break something else out of a box and Assemble... Cheers Dave

[@gazza4230]

Aww mate so soz to see this I’ve not maidend mine yet but I’ll definitely check battery is strapped in I recon that was your problem but we have all done that and I recon the hinge gave way with force of impact, I put hinge tape on my jets lately but was so sad to see this but I think it’s fixable with some of my planes I put carbon fibre strips in to give extra strength I did it with my red arrow and it did help with my second mishap I had the other week I flew it into a bush at full throttle and just ended up with cosmetic injuries lol , Gary 🇬🇧

[@FlankerTanker]

Hi Gazza - Well I guess SH*T happens - I tend to agree with what most are saying here - no doubt that the Battery not being strapped it means that it shifted forwards - silly mistake to make , I have changed my CG checking procedure now and even if I am just checking the CG the Battery will be strapped in - Lesson learnt the hard way - I left it a day and took a good look at the A10 - I decided to scrap it , removed useable parts and the rest goes into the Bin.. My E-Flite F15 has carbon strips to reinforce the nose... Its good to hear that the Red Arrow is still flying - Stay well See you soon - Martyn

[@patrickhickey3072]

R/x placement and I didn't see you do a range check

[@FlankerTanker]

None of the above, I actually did not secure the battery !!! and it shifted forward in flight - just because I do not show range checks on my videos does not mean I do not do them, because I do and I did.... Cheers

[@BRIANFORWARD1]

Hi martyn As an aircraft engineer AND A CRASH INVESTIGATOR FOR THE RAF..... I CAN HONESTLY SAY WITHOUT FEAR OF CONTRADICTION THE A10 IN MY PROFESSIONAL OPINION IS TOTALLY AND UTTERLY FORKED.......... right now for my 2 penyth worth.... DONT think it was the lipo front heavy SLUGGISH.. BUT CONTROLLABLE unlike tail heavy I think it's 1 of 2...... AILERON OR ENGINE FAILURE ON ONE OF THE Edfs. As for the broken Elevator couldn't cope with the force to correct the flight and caused hinge failure.... On a side note that lipo WHAT A BRILLIANT PAPER WEIGHT THAT'S GANA MAKE. If you remember my zohd ailerons were forked only preflight inspection stopped a bin liner being used the same as your HUSKY Elevator hinge the other day Or it just might have been that FRIDAY AFTERNOON THING...... Brilliant vid even with the promise of racoons eating people's head off..the hint of POSTMAN PAT giving a FIRST CLASS DELIVERY . After thought Try the aileron servo and both edfs.. You never know🤔🤔 BE LUCKY 👍👍👍👍👍👍🇬🇧🇬🇧🇬🇧🇬🇧🇬🇧 Brian

[@FlankerTanker]

I see Brian - are you trying to tell me - that without any Beating around the bush, and getting right to the matter in hand, without any unnecessary delay, that my A10 is Broken with a Capital "F".... !!!! . because if that is what you are saying - I totally and utterly agree......🤣🤣🤣🤣🤣🤣 - Problem is that if one of the EDF units proves to be Dead it could be CRASH Damage and not failure in flight - Regarding the LIPO now that it has been made Inert - I might look to see if I can get it into an acrylic block - and use it as you say a Paper weight.. oh and S*D the racoon and upright Postmen, its the farmers mountain of Bl**dy rotten Onions that will get you.......!!!!! but that's another story altogether.... Stay well Brian Martyn

@@FlankerTanker hi martyn Under close scrutiny is there a any chace you can determine any outer damage to the casing.. missing magnets.. scoring on the armature..... Go forensic you've got the same magnification head set as me..... I LOVE A MYSTERY IM LIKE A DOG WITH A BONE..... 👍👍👍🇬🇧🇬🇧🇬🇧🇬🇧 Brian

[@papapsadventures6119]

My opinion is that in like most crashes it was a myriad of things that contributed to the demise. Pretty good guess the aileron hinge was faulty from manufacturer, like the old story goes never buy a car that was built on a Monday or Friday. Sorry for your loss my friend 😢. What did you salvage?

[@FlankerTanker]

Hi PA Pap's - Indeed your comment has good wisdom and advice - only one thing was missing - and that was my Stupidity for leaving the battery unsecured in the aircraft - as they say and the proof is in the video - it was an accident waiting to happen... and it did !!!! - thanks for your comment - Stripped the A10 for parts (servos, motors, fan units, pushrod..etc.... the rest is in the BIn... Cheers...

[@jimsoyak90]

Sorry to see m8,I still have to maiden mine/

[@FlankerTanker]

All I can say is make sure you secure the Battery, and check the hinges...- it flew well, for the short time it was able to do so... good luck , I am sure your maiden will be fine...

[@purcellrcaviationchannel]

Gutted for you, Martyn. And I do believe that it's even beyond the scope of H*t gLu* in terms of resurrection. Best scrapped and then move on. Personally, I've had ailerons get ripped off in a bad nose-in... I think it's a result of the plane not going in truly vertical, but at a slight angle. The impact shockwave energy resonates through the airframe out to the extremities, where a whiplash action would take place. Outside of that, I'd blame Brian...

[@BRIANFORWARD1]

Cheers Gina..... Hahahahahahaha You've seen through my cunning plan...... I did have an arrangement with the farmer to burn his stubble but the bloody battery never went up... Dam I say DAM!!!!!!! I have to give the farmer that side of ham back......

[@ironmover5800]

My maiden was scary as well , balanced level on cg with batt full forward , ran 300 ft almost didn’t get up off runway , took full elevator to keep level flight , trimmed a lot and that helped but not 100% …..landing was full elevator to just get a 3 point landing , +1 moved battery back 1 inch and flys good there , I used the red dots on top of wings for CG Sorry to see this plane crash as I like mine alot and think you would also ……not sure I can “like “ this vid

[@FlankerTanker]

Hi Ironmover - oh wow sounds that you had your work cut-out to on the maiden - mine was short and sweet - (ISH) ... while it was flying it felt good....then. Well the rest is recorded for history, thanks for your comment and I am pleased your A10 now has a good CG and hope you get a lot of fun flights from it, as for me I am going to see what box I can open from my store ... Stay safe Martyn

[@seanbarrie8713]

So sorry dude, what a PITA for you! I don’t have the experience to advise what the potential problem was but expect it to be one of the two suggestions or a combination of both. I feel your pain though as nobody likes to see a maiden like this. Take care.

Hi Sean - for some reason I don't feel too bad about it - I mean don't get me wrong - I kick myself for not doing that Strap up - but as for the Loss - well as I had not flying time on it, I am not really going to miss it - the cost hurts LOL - but not the loss..... I have stripped it for parts and will see what I can replace it with from the stock pile I have... I feel an Unboxing and build video coming up - Stay well - thanks for your comment Sean - Don't let my stupid actions put you off - Martyn
