Thread: Unexplained crash
25/07/2018 18:04:18

Hi Julian,

I quarantined the 'suspect' flight set for now. I'm flying the old hack with a GWS ppm receiver and Futaba 3001's with no issues to date. I'm happy the tx is behaving it's self so far.......confidence in it is returning.

I'm torn between trying the suspect kit or just binning it. The only thing causing a bit of doubt is of the servo's failed and got very hot on bench test after the event. the receiver was a Futaba G3 2048

Thanks, I'll get somebody to have a look........I'm one of the few people that doesn't use Facebook

Any Ripmax Bullet's out there for sale

Stil searching and I thought I'd throw this up again on the off chance there's one available

Thread: expo for beginners yes or no ?

in my humble opinion. it should be learn to fly with the basics first........no expo or mixing. There's nothing wrong with a little rates but be wary of dialling in too much as you could lose control surface authority as you slow up on landing approach.

thing is its a matter of opinion ( said the man with the wooden leg) if it works for you great........at the end of the day there's no one size fits all

Welcome to the club lol...........getting in and out of the sports car is a real bugger too

Thread: fav model of all time

Fantastic video, couldn't take my eyes off it. brought a lot of memories back from 'going flying' with dad. At the time it was single channel and the flight pack was powered by a rubber driven esc. thing in trying to remember is the button control. was it single press for right rudder with a quick double blip for left or was it the other way round......

29/06/2018 18:14:50

We really are a diverse bunch. for all the choices, I don't think there is one duplicate.

The pics are great, if I can sus how to upload I'll put a few up.........albeit, somewhat dated!!

it's like desert island discs with one tune lol

28/06/2018 23:27:42

just thought I'd post this for a bit of fun........of all the models you've had since you started modelling if you could only have one of them what would it be.? (doesn't matter what category, could be f/f, c/l, r/c etc ....anything goes)

I'll kick things off by saying mine is Irvine 53 powered hanger 9 Aresti

Update Time,

3 flights not a glitch all worked fine, One I've had a few more outings I'll put it down to outgoing servo

24/06/2018 10:07:46

Thing is we may never know the exact cause. If today goes ok I'll probably continue to test until happy all's ok and bin the old flight set........I appreciate I could be throwing good kit out but for the sake of peace of mind I'll just need to live with it.

if I get a repeat, it's Tx off to get checked and if that doesn't solve it it's a load of 35 MHz stuff in the bin and move to 2.4

PS fail safe set to kill throttle only and freq changed to 75. I'll post the result

Thanks again to all for taking the time to respond

Hi Dennis,

no glider pilots anywhere near, the nearest suitable hills are miles away. I've flown on 76 for 15years plus without as much as a glitch.

Hi Onetenor

I'm fairly sure the root cause was down to the failing servo. I'm struggling to see how frequency could effect the outcome.....for the amount of heat and current generated could potentially cause random Rx function.

all of that said, it's test time this afternoon with a new switch, battery ( power cycled and timed a few times)and a known good flight pack in an old ( bit tatty but structurally sound) airframe,.........so fingers crossed

23/06/2018 12:09:17

I'l try and answer all 3 in the one go

Dennis,

we're just a small club with about 20 members. I believe there is a club scanner about and am hoping we can use it this weekend. When the incidents happened there were only 2 of us at the site and the other members gear whilst not switched on is on 84, mine is 76

Peter

Haven't checked the buddy switch, but good call, will give it a try

BEB

Thanks for the info, I'll give it a go

22/06/2018 21:08:06

I'm not sure of the physical arial connections, but I've tried aerial up and Arial down range checking. I checked aerial up at twice the distance of the crash with not a glitch......and that included the use of mobile phones for coms to ensure signal given and reaction were good......all performed perfectly. The only thing I haven't tried is range test aerial up with engine running.

At this stage my thinking is

1. the elevator servo that failed shortly after the incident

2. tx fault

3. interference

I've tried everything I can think of and can't get the fault to re occur or system failure. It's test time on Sunday afternoon so fingers crossed and praying for cause 1

but in the mean time happy to consider all suggestions

22/06/2018 20:23:39

Thanks, I wasn't aware of that.

Quick Question,

In preparation for Sunday's test, I'm in the process of dotting i's and crossing the t's. I have an old and somewhat tatty precedent fun fly airframe. with a known good set of gear fitted plus new battery and switch. Everything has been checked out static several times. One question is what sort of range should I get with the arial removed from the tx ( futaba 12z on 35mhz)

19/06/2018 14:55:01


Hi AVC,

I've Just checked the flight pack voltage (Futaba battery checker) and its still showing 6.3v. with regard to the f/s if the throttle is open at all it closes on Tx power off all other servo's remain static. Upon power up they give a very quick & very small glitch, nothing that'd raise any concern.

I've got an old precedent fun-fly airframe which I'm thinking of kitting out with a known good flight set & see what happens......of there's any grief I'd need to consider looking at interference or Tx issue.

To All,

Thanks for all your contributions, certainly a lot to consider. If I find anything other than the "hot" servo I'll post it

On a separate note - how do I post a picture or create an album on here

19/06/2018 12:36:26

the failsafe was not set, and on default. if I switch the tx off first the throttle closes, nothing else moves. I can't tell how the throttle servo was at impact........to the best of my knowledge it went in at full chat and the fuselage is mangled all the way back to the win t/e

the model has a 2 piece wing which attaches to the fuselage sides and a joining tube. The wings ripped two lumps out of the fuselage spilling the radio gear and the section from wing l/e to firewall is just mush

my initial feeling was to throw the whole lot in the bin bag, but as I was gathering the bits common sense kicked in. Admittedly I did look at the carb and the trottle was closed, but I suspect this was due to the crash as opposed to servo action

having found a servo meltdown post crash is a possible cause but I'm not 100% convinced, it could also be tx fault or external interference and it's how to eliminate these that's concerning me

19/06/2018 11:04:09

Hi Don,

the bits will most likely have a future date with the bin........the only thing stopping me at the minute is the desire to get to the root cause.

19/06/2018 11:00:12

Hi AVC

yes, rudder and elevator were HiTec servo's
