ive got a new futaba 9zap wc 2. it came with a r309dps reciever. i put it in a wm 300. 80 inch span. i flew this plane three times. it flew really really good. it also had a nickel metal battery 2700 ma. all hitec digitals. 5625's and a 5945 for rudder. took lots of time getting everything right. battery was fully charged. i take this plane up for the third time. was gonig so good. then while in a knife edge. went to come out of it. and nothing happened. no ail. rudder. elev. throttle nothing. just like i shut off my radio. the throttle was wide open or close to it. from running in knife edge. it attempted to go left right and left. i was running the sticks hoping. any how into the ground it went. and destroyed it. about like a bagdad bombing. nothing left. exept for my moki and radio gear. wich is good. and i lost my new bolly prop. any how. has anyone used this new synthsizer rec. and have u had any promblems. i bought the same plane the very next day. got two new batterys. different ones. and i got a new r149dp. actually ive got two of these recievers. i dont know what happened. battery was charged and everthing was plugged in. came home hooked up all my servos. and ran them without fail. so three flights and my new butiful plane is in a trash bag. but my new one is about one day from being ready for flight. any how just wondering;. about these two different recievers. ive herd the 149dp is a very good reciever. its not my radio cause it flys my other planes fine. just this one crashed. and its the only one with this 309 in it. so im afraid to use it. so going to 149 and hope it does not happen again. cant afford to buy a new one over and over. any help on these recievers would be great.. its not as bad after uve flown one about 100 times or so and somthing happens. but when its so new and shiny it really really sucksssssssssssss.. thanks bill
i really loved this plane.

roadracer, sorry to hear of your crash . Do you think the switch might be suspect, or possibly a loose connection somewhere?

Roadracer,

Check the Hitec site. There is a date code on your servos. If they were produced before a certain date (can't remember), you may have issues.

I had to braid all my leads to get rid of the glitching with the 309 and the 149 to be able to use Hitec 5925's. All my servos are the ones that need to go back in to Hitec for reprogramming.

They work fine with my PPM receivers.

Be careful. Do a good range check w/o engine and with. And make sure to do it at several diferent RPM ranges. I had one servo that started to chatter, then all the rest followed it, even with the fail safe set. The chatter came from the servos not the receiver.

I run my antenna through a tube in the fuse (GP Giles 202). When I got the glitching I pulled it out and tried different angles. Nothing helped until I braided the extensions.

After braiding all the extensions (24" HD extensions) everything settled down. I have not had my servos reprogrammed yet. I even put the antena back in the tube inside the fuse. So far so good. But I don't intend to fly my 80" cap w/o getting the servos reprogrammed.

Hope this helps,

Scott

A friend of mien just yesterday test fkeww a jamara cap 230 w/ saito 120. Hed spent ages, just liek yourself, getting it perfect.


First flight was fine, second flight he did a stall turn, then it went into an uncontrollable full throttle flat spin.

I will check iwht him what rx it was as i have my suspisions it may be the same! He didnt set the failsafe unfortunately.... did you? I trust theyre pcm aren't they?

when u said u braided the extensions. how did u do this. i was wondering what ur brading looked like. if its what im thinking of. did u just twist them around like a pencil or somthing. thanks for all the info

asked the 'friend of mine' and his incident involved a 138 rx so no similarity then.

Roadracer,

I removed the three pins from one end. Seperated the wires and braided them. Just like you would do with a girls hair.

That's a little on the "overdone" side of things.

You really just need to twist the extension about itself. You are looking for ~ 1.5 twists/inch.

One other note. This will shorten your extensions up! I lost about 3" after braiding mine. I've heard others who used the twist method that have lost 4".

Best of luck,

Scott

I bought my 9ZAPS in 1993 with the 309 receiver and it's been ok. With synthesized equipment though, more frequent "tune ups" are recommended by Futaba. You did say your equipment was new right? What were the results of the range check_bob

i was probably 30 or so paces. i just kinda looked at how far i was. cant say in feet exactly. but when i get my new one done wich is about done. im going to range check it running not running. and prbably twice. ive tried to cover my rear in every wich way this time. ive braded all my ext.. the reciever is in the thickest foam i could find. but this time i reaplaced the switch. battery and reciever with new. the only thing i kept the same is my servos. i have a hitec programmer. with the newest software. my servos are all newer. so they did not fall under the hitec websites needing reprogramed. but i did it anyway. so ill be balancing it tonight. then somtime this week if its not windy and rainy and cold and snowy. ill try it again.. can u believe woke up to snow on the ground. man i get tired of living in ohio... thnaks again for all the input

I always thought the pins were "pressed" in place once inside the connector (with that funky little $30 pair of plyers) . I wasn't aware they could be removed and put back in place.

The Edge,

I ues an old #11 blade with the very tip broken off to gently lift the plastic tab. Lift just enough to let the pin slip out. otherwise you can break off the plastic tab, or bend it to the point that it no longer holds the pin tight.

As for seperating the wires. That is the toughest part. Be very careful not to strip the insulation from the wire. Hobbico HD (20 guage) extensions are probably the easiest I've done. Hitec servo leads are the toughest.

Again, Braiding is way overboard, but I like the way it looks in comparison to just twisting the wire over itself.

Roadracer,

Snow! Egads man, haven't you heard of the winter migration to Florida! You've missed Daytona bike week!

Best of luck. Hope this one does it for you!

Scott

Wow, I learned something new today. Thanks Scott. I usually just seperate the wires, twist them, run a heat gun over them a little and then clamp it to board (all stretched out) for about a day.

The braiding looks to be the way to go and you probably don't loose as much length (I lost about 2-3 inches off a 24" lead).

Thanks again.........Mark

id like to migrate. i get so sick of ohio winters and springs. man things have changed since i was a kid. i need to move west with my brother or somthing. when u only have about 4 months out of a year that u can actually go out and do somthing its a mirracle.......... hope my old girl flys good. im ready to balance it. then wait for nice weather and fly. ive checked and quadrupal checked everything. dont want to see my buety go into the ground again..
