Hello Buzz.

i made a small video a couple of months ago.

Hi Didier,
What kind of linear actuator did you use for sliding canopy and where did you buy it.

Craig B.

looks like an Actuonix linear actuator to me.

I have this same kit and mine fly well but I notice the stab incident requires a lot of down trim, is this normal?

LtMash1A

I have the same issue. The plane flies well even with the down trim. I'm wondering if shiming the engine down a couple of degrees will fix it.

Most likely there is a bit of incidence into the stab that causes the need for trim. You should not change the engine thrust unless you notice a difference in trim at different throttle settings.
It doesn't hurt anything to fly with some trim as long as it's linear through the speed envelope.

I finally picked up another Zero to replace the one I crashed. I spent a bit more time on the cockpit update for this one. Here's the cockpit, and the Best Pilots Saburo that will go in it.

Why did you crash your Zero? Human error or equipment failure? I wonder how many flights you can do without repairs to the airframe. Stock glue used in this model seems to me fragile.
Btw, you did great job with upgrading stock cockpit to present stage. In the begining I had the same idea but finally gave up and went for scratch build.

My Zero crash was human error. It flew so good I got a bit too confident on a bad visibility day. I did some extra re-enforcement around the wing tube area on my new one. Everything else should hold up decent, especially with a twin cylinder engine. If you used a big single in this airframe I think the vibration would be hard on it. Even so, I'll be keeping an eye on everything to make sure it stays sturdy. I liked the plane enough that I wanted another. I switched to Robart air retracts using the stock struts, the stock electrics were quite slow with the power I was using. The stock cockpit is quite basic, but it's not a bad starting point. Starting over I could have made a more scale cockpit, but the amount of time would have been much greater.

Awwwh c'mon, can't you blame the radio?

fw190

My Feedback: (37)

Mine needed a lot of repairs and I cant blame the radio either. I was heavy handed on the Zero in the air so the wing support plywood cracked and the rear aluminum tube bent. I gutted and replaced the cheap plywood with aircraft ply laminated with carbon fiber, also replaced the rear aluminum tube with a carbon tube. I can bend the aluminum by stepping on it but cant do that with the replacement carbon tube. Anyways the DLE 85 was just too much vibration for this plane so I put in my GT80 instead. The rear canopy hatch broke and the entire cockpit ejected during a landing. It is gonna take some many flights to break in the new GT80 but at least I know it will not be shaken apart.

Hi. I totally missed your question. It is a

Actuonix L16 Actuator 100 mm 63:1 6V Servo type

LtMash1A

Did you you use baffles for the engine?. Many people say you have to have them, but I have seen a lot of 84's and 90's fly without them and seem to do fine.

Hi Guys
Im stuck with this tail wheel retract !
Im using a Spektrum DX9 TX
I have installed a Hitec Hs 70mg (analog) servo as the retract servo into channel 8 (aux3) which i have assigned to the gear channel.
I can move it in sub trim .....but it won't move at all from the switch.

Is there a better way ? Do i need a Digital servo for this ?

Any help would be great
cheers
Pete

darod07

Hi,
You don't need digital servo for this....
What I understand your switch assigned to aux3 is giving no reaction to servo? Check switch setup for this channel.
I use same DX9 radio. I use Y servo cable. One output goes to main retracts controller, 2nd output to tail retract ( I use digital servo programmed to operate tail retract slowly)

mackone

Thanks Darod
I didn't realise there is a switch assign section in the channel assign menu. Its all working now.

I have another DX9 issue you can help with, I have channel 5 Gear channel now assigned Aux3, but i can't get it back to Gear ??

cheers

Doesn't the tailwheel retract plug into the the same controller unit that that the mains plug into?Operating the mains will operate the tailwheel. The polarities can be reversed if they should operate in different directions.

No , the tailwheel will drive off of the receiver channel that inputs to your retract controller (y harness or mix channels to slave another chanel to your retract channel ). The main retract motors are 2 way bi-direction circuits . To reverse operation direction of the mains you just reverse the connector at the retract controller output for the main retract , just flip the connector 180 deg

darod07

I had the same issue when was using original 9ch receiver from DX9 set. Unfortunately it was long time ago and I can't remember now what I did. The thing I remember ...somebody was describing this on forum, maybe even this one.

little search and there it is:

Hey Darod
I read the thread.......still makes my brain hurt.
I'll deal with that tomorrow .

Thanks everyone for the Help.
Stay safe

Hi Pete,
It was not easy to me but after all most important sentence to me from this thread is:
"Think of the servo port named "GEAR" as really being "AUX0" - it really has nothing special about it. It's just an auxiliary function."

Honestly, I preffered my old DX8 radio, much simpler for programming. DX9 has too many options for me, some I still don't understand after 2 years of playing with it.
Now I use 12ch receiver and there is no more "Gear" channel on it, means no more issue with Gear assignment...

My Feedback: (60)

I have seen this channel "name" mapping issue before . On some tx's the issue is created when you first set up your wing type , elev type and flap type . These selections will give you pre mapped channel names and some pre configured channel mixing . Whereas if you set up a certain wing type , ailerons and flaps may be on different channels than you would usually see . The same pre mapping can determine if you have a gear channel or and aux channel . Renaming a channel after the fact can reset the pre mapping to a different model type , wing type etc. Sometimes the only way to change the channel name back to its original configuration is to go back and re-select the correct aircraft configuration with regard to wing type , elev type , flap type etc. This unfortunately may clear any reversing , atv , expo etc that you have already setup . The key take away is to be sure that you are using the correct initial model type configuration selections that give you the correct channel mapping and channel names that you need for each individual model that you set up.

From the Thread that Darod sent The DX9 won't let the channel Gear = Gear go back to Gear = Gear if you change it ....

Are you guys using a seperate battery for the Gear Box ?
Im using a 12 channel power safe receiver .......when i tested the retract box I just plugged the power into channel 11 which is not usable with my radio.
Is this ok ?

cheers

My Feedback: (60)

Pete ,Just so I'm understanding you correctly , Are you saying that you added a servo connector to the Red and Black power supply wires of the TopRC retract controller and you are plugging that into a channel on your receiver as a power source ? lf so , I wouldn't advise doing that . The power required to " amp out " the retract travel may be more than your receiver bus may provide or less amperage than the retract controller needs , either one may let some of that " built in " smoke - out ...not good ...
I use a dedicated 2 cell 4000 mAh LiPo battery to power just the retract controller . The rx provides only the actuation input to the retract module .

darod07

CK1 is right....
Use separate battery for gear controller.
Although Spektrum 12ch receiver can withstand 10 amps as per specs. I wouldn't try to take it to the max.

mackone

Thanks CK
Thats why i asked .......My Zero is second hand so I have the previous owners equipment and he knows his stuff, I just like to ask questions when I'm not 100% sure.
I will set it up for another battery.
cheers
