I have a pixi20p and a pixi7p I am about to install. The 7p comes setup optimised for my lipo's. but the 20p needs to be progammed a bit for my lipo's(well thats what it suggest) My problem lies in the fact that both esc's progams are entered the same way. If i hook both these on my heli and try to set up the 20p it will change my 7p too I believe. Anyone have an idea for me?

Justin,
It will not change pixie-7p setting because you program ecs via channel 3 which connected to pixie-20p .
For Pixie-20P: connect it to channel 3.
1)Follow instruction to get into programming mode.
2)Programming Setting 1 –Cutoff Voltage: 6 volt.
3)Programming Setting 2 –Cutoff Type: soft cutoff.
4)Programming Setting 3 – Throttle Range: Fixed throttle range.

You can do the same for pixie-7p but i1st, it needs to connect channel 3 to program.
Regards

awsome....I knew I could count on you rick lol......thanx now I need to wait till hopefully tommorow to get my tx and then I still have to wait a few more days for my new servos.....should have bought from hellihobby...alot faster shipping. its been over a week for my tx to come in...and Just the other day I ordered my servos from the same place as the tx....the watiing game .

hey rick...should I setup my pixi even though I wont have any sevos hooked up or should I wait for my servos?

If you already have Rx, Tx, ecs, go ahead and program it. You dont need servos connected during programming.
BTW, Found out my main gear/shaft is ruined. Going to get replacement and then test out "inverted mount J250".
Regards

Awsome... I was talking to my buddy today about the inverted setup..... good luck on the gear. you going to get one with a pin in the bottom? I want one with a pin in it but am not sure what one I need with this heli...... I hear the inverted setup works pretty good...cant wait to hear results.

I've bought Hummingbird stock gear/shaft yesterday. Hummingbird gear/shaft has pin on the bottom. Ran couple test flights with inverted J250/stock blades. It has more power and runs smoother but I need to test it with like90 blades which I've ruined last week. Right now I'm in process of installing thin heatshrink on stock blades to gain some headspeed. Will keep you posted.
Regards

got the servos today....will put together tonight or in the morning. I bought a new soldering iron and some tin stuff for it and I got a multimeter so incase anyone askes a question about the amps and stuff I can find out I also bought a inline fuse....should I only put one on the main or should I put them on both....I got my gear puller today too. the only thing I didnt get was the like 90 blades and the bell-hiller mixer yet....probley on monday. Oh well ....at least I can get in the air with stock blades.

Ok I programmed the main and then I unhooked the tail esc from the hh gyro and put it in channel 3 and programmed that.I hope thats what I was supposed to do. I am glueing the tail prop on now...I think im going back to a stock tail setup though. I hate the dd system...having to glue the prop on all the time and all that...Plus it makes me have my lipo way out front....I like the spot the g-10 frame has for it under neath. But I will give you a pic as soon as the camera gets its battery charged up agin... I was wondering why when I put my multi meter on the tail wires that it makes the blades on the main spin...kinda weird. But like I said ill probley have some problems as I dont have good luck.

Justin,
That's correct. Be sure to connect it back to gyro when done.
You may want to try dual tail motor setup. That's what I have on my Jabo now (i do swap back&fort between DD and Dual).
Check out like90.com for dual tail mod.

hey rick...got any clue why I would have tail power at all? My motor dont spin a bit....I will do some testing to see if I can find out what the problem is.....I moved the chips around so they werent so clustered cause I kept having twitching going on....mabey the motor dont have enough capacitors? its only got one now.

You need to arm tail ecs at power up. Try the following:
1) Tx power on & throttle at lowest.
2) Connect bat.
3) Pull rudder to left on hold 5-10 seconds (this will reset & arm tail motor).
Let me know.

well I can get it to turn on the tail(arm) but my tail is pulsating. it only shoots jolts of power. you think I need to charge this lipo up? I cant get off the ground full throttle so I think that may be a reason? Not too sure....how much fiddling with the screw on the hh gyro did you have to do?

ALso when I cut the power or run at very low head speed the heli screaches....almost sounds like a break that stops the motor....you think it could be my johnson 250...if so I have more motors...but like I said it sounds almost like a break of some sort. weird

Justin,
Sound like you have 2 seperate issues:
1) Tail:
Did you connect all 3 wires from tail ecs to gyro? Try signal wire only.
2) Main motor:
- Try 2-3 drops of motor oil to J250 to see if that help.
- Make sure main gear not too tight with main motor pinion.
Regards

ok well you cought me lol I had all 3 hooked up.....I thought that was what made it work but it was the arming you told me to do that made it work lol. I unplugged the wires and now it doesnt jolt hardly at all. I do need more charge in my pack though. So I will have to wait for the rain to stop so i can go outside and hook my damn charger up to my jepp. It only has friggen clamps on it for a power source. I have a wall plug that makes a outlet into a cig lighter plugin but dont know if I can convert a adapter for this to be used for my charger. I fear my cluelessness. I am going to order all my parts needed for my jabo to rebuild. That way ill have something to fly if and when I break something on my new one. ill post a pic too but in a different thread.

Justin,
You can try a computer ps as power source so you dont have to use car battery.
a computer ps supplys 12V with 2amp(or more) should be ok.

Pixie ECS light should be blinking after you power up. That's normal.

cool.....So I just rip the power source out of an old pc sounds easy enough.
I went back to factory tail...Could stand gluing the props back on after I smash stuff......The heading hold is kinda shady still but I am waitting for my battery to get fully charged.....what do you use for a charger for your thunder pack? I use the hobbico quick field charger mkII pro series.....It looks nice enough but not sure when it is fully charged lol I guess I need to re-read the instructions.

I use BEL 2-3 cell lipo charger connected to an old computer ps.
For gyro, keep gain in center at first, take off and note which way it drift then make a tiny adjustment to get sweet spot. Make sure to pull Tx rudder all the way to left when making adjustment (this will reset your tail). You should get locked tail due to better tail ecs (pixie-7p) than mine (ics-50).

I also have the same noise from the jonson, where should i try the motor oil, actually in the motor...?

Rgds, Craig

Dalai,
I put 2-3 drops of motor oil to both end of the motor shaft. This seems to ease up J250 motor.
Regards

hey rick. I have had great improvments today...I got the stock tail on. I use the all electronics motors...for the tail and it worked alot better once I put the wires on the right way I had alot of spinning lol. But once i got it on right it was awsome. I really saw and felt the heading hold work. It is so damn cool to not have to worry about the tail. I also went to the auto parts store and picked up a cig lighter plug in. I am going to use this to plug my charger into a 110-> 12v dc so I believe this should work...right? And while doing this I remembered that I needed longer servo arms to get the swah level as well as the horns level....well my buddy bought the servo arm extenders so I used them for the servo arms.....I broke a swash ball link while doing this. It is the lower rear ball. So i spliced it together with another broken swash plate and i was putting it all back together and happen to have trouble getting the swash ball mod over the shaft. I ended up busting the ball mod and I ended up breaking my swashplate again. To make a long story short. I wont be flying for a few days.....ooohhh I just remembered my buddy has a few extra swashplates.....I could be flying again tonight.....I just wanted to keep you posted. I will post pics either tonight or tommorrow. Problems were fixed once I went to stock tail.

Glad to know you got it working as expected, minus swashplate issue.
BTW, I've finished inverted J250 mod ---> seems to have more power and run quiter.
Currently working on bell-hiller mixer mod (~$5.00)... How is your bell-hiller mixer compare to stock?
Regards

well to tell you the truth...I havent put it on yet. I didnt want too many upgrades put on at once. i wanted to feel the difference once I got this one flying pretty good. Come to think or it I might put it on my stock jabo. I should have the parts in a few days to put one together (jabo that is) I love the new heli I have now. I am thinking about renaming it. That way I can refure to my stock jabo and my (place new name here). I just havent thought of a good new name. Jabzilla....lol mabey need more time to think....But yea the bell hiller mixer looks real easy to make. If you need specs. let me know. I am glad to here the j250 is doing good for ya. how bout the gear thing?

I am thinking about chopping my can on my j250 to reduce heat a bit...speaking of heat....when I wired the tail backwords it got so Hot I could hardley touch it.....it actually probley could have been hot enough to solder.lol mabey not that hot but man it was hot....wont be long and it will probley be shot....good thing i got about 9 more.

You have a good point doing mod one by one so you can see the differences. How about rename your new heli to "Jabba" as in StarWars:Return of Jedi .
Anyway, I've replaced stripped gear with hummingbird's stock gear and all is fine. I've also tried Bell-Hiller mixer mod and it's much more responsive. It's sort of re-learning cyclic controls and need sometimes to get used to it. See attached for Bell-Hiller mod (cost me nothing) and inverted J250 mod.

looks really good. I wish I could do inverted motor...My g-10 frame is in the way. Oh well.... Mabey I will try to wrap some wires together to make it look a bit better. It kinda looks like wires hanging out everywere....I hope I can get my cover on still...
