Composite-ARF 300SX is Ready!

[eagle1]

sorry for the long wait I was at the lake for 3 days just got back tonight.
the last time I tried it we range checked and it is way less range with engine running than not.
I still have to replace the gaskets on the headers,if this does not work I am going back to ppm and a i4c isolator I should have the results by monday

[eagle1]

I just got through checking the exhaust gaskets, I thought that I had metal inlaid gaskets on this plane but I do not.I did not go flying this sunday so I do not know that what I did fixed the glitch,hopefully I will burn some gas this week and let ya'll know how it did or didn't

hey are you haveing a glitching problem?or are you going in to lock out? give us the break down on your excact equipment on board! maybe we can all help narrow down the problem! instead of taking a chance with the maybe i got itfixed!

with the ppm recievers I was having a glitching problem but with the pcm recievers I am getting some form of lockout.
I am running twin pcm recievers,139's,two 5200 fromeco lithium-ion airborn packs,a sr-10 for elevators(so I do not have to mix in a channel)one servo is reversed through this setup,I have both antenna's running up both sides if the turtle deck and exiting the top on each side of the fin where it meets the fuse,
I sent some pictures to Don at Don's Hobby Shop and he has given me some things to take heed on, first my ignition switch is only 4 inches away from my airborn battery pack,my rx's are only 1 and a half inches away from the pull-pull cables, and my antenna's are too close together leaving the plane.
the problem occures at about 50 to 60 feet away from the plane when engine is running on the range check,I can pull out one section of the antenna at this distance and have full control of the plane,AJ told me that he thinks I am running out of signal at that distance but this is not ene 40% of the range with antenna completely colapsed. the instructions say that in the Z series of radios that you should have one section to be extended but I have a 9c radio.
I know that each setup is different on each plane but if you could see the setup in the 330L I have all packs within a 6 inch radius of the ingition or packs and I am only running the one pm rx with a servo isolator and very seldom do I see a wing tip dip usually its just a short glitch and do not see it too often not enough to do anything about it.
But on this plane when I run up to full throttle I have lock out .

Looking at the pics from the 1st post, there's a couple of things that I would think about changing but they probably don't have to do with your problem. I would 'loosen' up the receivers. The vibration can transfer to them if they are strapped down to tight.. even with foam. The location of the receivers are pretty close to the pull pull system also... Either one though probably isn't the cause.

Just to troubleshoot it a little you can try a couple of things...

Make the receiver and antennae movable just to see if you can get better reception. Take them loose from their mount and use some tape to put them in different places of the fuse then range check (or have someone hold them in different positions). It's definitely easier if you're only using 1 receiver. Now that we mentioned 1 receiver, try using just 1 and see if you still get the same problems.. Once you find the best position, then remount them.

Minimize the items installed.. ie, If the throttle is what's showing the lockout then take 1 receiver, hook up the throttle to it and just a nihm battery, nothing else, and check it to see if you're still getting interference. Keep adding items until you find what triggers it.

this is how the setup is now and the way it was the last time I tried it at the field but that sounds reasonable to try one servo at a time

[eagle1]

first picture is of the rx,reg, and switch
second is ignition switch and pack,ign in background
third is throttle servo fuel dot and ign in the back ground
bottom picture is that of both airborn switches,rudder servos,pull-pull cables,regs,rx's and two msa-10's for ailerons on the pictures on page 3

[eagle1]

I have not moved the rx's or the ign switch nor the antenna's.
I am waiting on a set of crimping pliers and connector ends so I can make everything shorter and farther apart at the same time, I spent about 30 mnutes with Don on the phone about this,It just amazes me that all my batteries on the Extra330L are within 6 inches of one another,3 swithes are mounted as close as possible to one another, flying ppm and I have less trouble out of that plane than this one, I am going to give this setup one more chance then I will go to the exact same setup as the 330L.
I have not used pcm until now and so far I do not like the lockout that it shows,it would be nice if it only would hit the one side but it gets both sides and locks them both out,throttle servo is plugged into the one reciever on the left of the plane and the elevators on on the other with an sr10 with revo.I will get in there to remount everything tonight or tomorrow and give this a try

[eagle1]

Oh and BTW the airplane that I am holding I am thinking about selling,no engine or electronics, airframe only for 500 never been in a crash one rough landing skidded both wing tips , monokote from firewall back 6 inchesw is ripping off, this plane I had a smoke system in e-mail or pm if you are interested, will not ship but I will drive 150 miles.
sorry its' a greatplanes 1/3 scale extra 330L, I built this plane about 2 years ago I first had a Fuji BT86 TWIN then went to DA-100.. the graphic on the cowl I had prayed clear over it now the clear is turning black. all wood came out about 26 lbs

alrighty folks heres the run down on todays work out
I took the pcm rx's out and tried ppm could not get 30ft from plane while running
I disconnected the right side battery and reg same
I took out all packs and regs tried staight battery and rec, better 50ft
I I put everything back to 1 rx and a 6v nm pack bump at 70% of range engine off
while engine is running,glitching is bad with straight ppm.
moved battery and pcm rx to the center of fuse ran antenna out the top and taped,
put everything on reciever,tried the one 7.4 pack and reg, made things worse
I put regular pack straight to rx and now I can almost get my 90%
the range I tried with engine off back to the plane was around 100 paces,about 300 ft. no glitching, it tries to lock out at about 60 to 70 paces.
I don't kow of anything else to ry got any suggestions???????????PLEASE????

[eagle1]

OK OK OK I called don again and we talked about distance between headers and cans, took my headers off they were not touching but one side is very close less than a 1/16 of an inch, so I cut a 1/2 inch off both headers and gained another 20 paces,now remember that a step for me is about 3 feet per step that means that I am far enough away that anything can happen, Don said that is very good for the radio I have. he was very surprised that I am getting 300 feet with engine off,that is almost double what futaba says you should get,this is not an exageration on my part I just simply get tired of walking,now lock starts at about 75 to 80 paces thats better than 200 ft. with 9.5 volts shown on tx.
mind you that I am doing this with one rx and a nickel metal pack, Don suggested that I put everything back like it was and try it again, he also told me to put the ailerons from one side of the plane and the elevator rom the other side to one rx, another words crisscross the alierons and the elevators so if one goes out that the other one would act like a elivon combo, makes better since than running the left side on 1 and the right on the other, my tx battery is now finished charging so back out side i go,wish me luck I have been out there all day trying different things,just a few more tests and hopefully all will be good and then I can finally fly this beautiful bird,its been on the building board more than its landing gear........here we go

[eagle1]

alrighty then i put every thing back like the last pictures I posted and tried it again.............EUREKA.....I BELIEVE WE HAVE A WINNER........................
tested it at 165 ft rear to side of the plane and did not see any lock out this time, the only thing left for me to do is to shorten the aileron extentions and take the sr10 synchronizer off the elevator and add long extentions to each rx for the elevator.
hopefully it will fly the same as the ground test when this last time man its been a long time coming,I even left the antenna the same as I had them exiting the same places a before.Don has given me alot of good info and I would recommend him highly for all your trouble shooting needs.just a few phone callls and some pictures is all it takes for him to help solve all your problems thanks a million Don. Saturday is going to be the big day for it's maiden flight if the test are the same at the field as they were here and for sure I will post some pictures of it on the ground and in the air,sorry I don't have a video camera,maybe someone will come with one and send me the video,I'm no hucker but I can cluck a little..lol and a thanks to Daniel is in order also for all the questions I have asked and the bugging at the field.

good to here let us know how it fly's

[eagle1]

if weather permits I will know something tomorrow,
I talked to Daniel about test flight and he said that he might go out there,if not I will try to pull off the test flight myself and leave the mixing for the later flights.
I will be taking better pictures of it tomorrow and I will post some of the plane in flight! I can't wait!!! thanks for all who tried to help me with this problem

never use zip ties directly on a rx....never use zip ties directly on a rx....never use zip ties directly on a rx...never use zip ties directly on a rx...

we are seeing way too much of this, it is the same as using no foam at all, use velcro straps or rubberbands or put foam all the way around the rx and zip tie just tight enough, less than half compressed. If you are worried about slipage use double sided tape between the fuse-foam-and rx
