Aviation models Yak 54 33% maiden and death

[solitare]

Sorry for your loss. I've never heard of this happening, but mine will be taped in from now on. Believe me we all know the feeling.

[JPrc]

I had a friend that had a brand new 31% Columbo Anderson extra go in about 2 months ago because the crystal came out of his receiver. I never taped in my crystals till 2 months ago.

A sad hideho to you,

First, all good answers/questions thus far. I have had a crystal pop out once, long ago so all mine are taped in, always. I have also left the ant. balled up so they allways get routed through a straw.

My next and only comment is the PCM vs PPM debate, and I will never go PCM.
I have learned to fly-through a hit/bump/interference just like you did, keep flying till all the parts stop moving, workin' the throttle etc.

I have never had a crash from a hit, several close calls, but was lucky enough to be able to fly-out in time to avert terra firma.

The whole premis of lock out just doesn't sit well with me, I am a control freak and need some assurance that regardless of a interference type hit, I need to be flying it under some control, rather than lock out/no control.

I am sincerly saddened by your crash, it just makes me sick to hear a maiden go in like yours did.

No other words can offer comfort for you at this time.
Unless it was that you just hit the lottery, and good luck, hope you do.

I am not trying to debate the ppm/pcm concept, only my personal experience/opinion.

Whew, man that sucks.

There's nothing wrong with PCM. i use PCM receivers. infact thats all i use. just because you have a PCM receiver dont mean you have to use it to it's full potential. i dont program nothing in mine. but thats a JR im not sure about FUTABA or the other brand's.

Dan, sorry to hear your loss. hope you get in the air quick with another.

P.S. i never had a crystal pop. but i do and have been taping mine in for about a year now.

Damm, on my way to the shed now.... I know a pair of comp-arf's, extra and yak, that have an appointmnet with some gaffer tape.

[BoneDoc]

Live and learn. Sorry about your loss though .

On a "Karma" note, did you call in "sick"? If so, that might be karma working on you .

Haven't looked at any of the other posts, but my guess is the xtal wasn't secured with tape?

Charged the radio did a range check both running and not running and not a twitch anywhere.So after checking that all was tight,no metal to metal,all extensions secure,bolts tight ,fueled up,no binding,good batteries,all was good and she was ready to fly. Now I am always a little shaky on the first flight of a new model trying to get a feel for her.This time was no different we ran her up pointed her down the runway and off she went.Boy was she sensitive to inputs so I threw the rate switch down from mids to lows and all was good.Now time to get her turned around and check out her stance on the first fly by I could tell where the sensitivity came from she was tail heavy, not unmanagable tell heavy but just enough that I would have to change some things around when I got her home.No big deal at all. I also noticed that the engine was a lillte rich in the mid range once again no biggie.So I kept flying around for a few more laps and decided to bring her in . I banked her around and head back to the other end of the field to set up to land.Well in the middle of the bank to turn around the engine rolls back to idle.I quickly notice that I am in PCM lock out and start praying that she will come out.I throttle back and then forward several times trying to get something to happen.Nothing she just kept on headed for the ground in a 45 degree downline on her left wing and then smack no more plane. Three 8411s wasted,brand new 3DUB 80 with pitts muffler wasted,three brand new lipo packs bye-bye, one new never flown 33% Yak WASTED!!!!!!!!! Now for the quiz boys.Can anybody tell me ,that was not there or or was told by someone there ,what I did not mention in the list above? I know better and have preached it to over and over yet the dumbass in me just could not remind me to do it. Take a few swipes at her boys and lets see who is paying attention.

Actually it's just "too heavy"

Well said Dennis, I hadn't considered that.

[WALKERS210]

Sorry for the loss, I have one in the shop now waiting for engine to arrive. Last Sat I went with a friend to purchase a kit built Edge 540 that had never been flown. The Edge was setup as close to perfect as any I have ever seen, dual receivers, dual batteries, 3W85 twin. Maiden flight, after about ten min of flight, pilot made the banking turn to line up on runway and then nothing. What really made the crash really bad was the pilot's wife was there to watch the maiden flight. Exam of carnage- crystals out- missing- gone. JR receivers also.

[SUPERFLYJAY]

hey all you J/R flyers with 30% planes and up take 10 seconds and a 5 cent piece of black electrical tape and tape those damn crystals in this is the second post ive read and the second costly crash ive seen in the last 10 days due to not taping them in. I had it happen to me on a 44% extra but fortunately i got the plane back. i have mixed emotions on setting failsafes for this reason, if the crystal falls out on a downline your done !!!! i had no failsafes set and fortunately i was able to land with half the plane operational, and with dual recievers and if you have a choke servo setup split it up throttle on one reciever and choke on the other, this way when it comes time to land and u lose the reciever that was working the throttle you can kill the engine with the choke servo.

Its fine to set the failsafes, just set all channels, not just throttle. I set all channels to go neutral. If I actually used two recievers, this would help in a one reciever lockout situation. Id definetly would have helped me with the big Yak at the Nall.

[lbkyak54]

Been there done that, on my sundancer, sounds like crystal came out, just as mine did. Hate see'm go in. I just about done with my 35% TOC Yak, I know i'll be shakin on my maiden flight.
