So a couple things prevented the maiden.

1. So I ran a lead off of one of the receiver batteries and used that to power the retract/brake unit. However, they still work without the lead plugged I. So they are getting power off the receiver which i was trying to avoid. Any ideas?

2. I am running a dual aileron, dual flap, and dual elevator program on the DX18 so the nosegear has to be in channel 11 on the rx but there is no way to mix it to the rudder because you can only mix the first 10 channels. ???

Thanks!

Yeah it’s the all in one unit. I have not tried to unplug from the jstt yet. I will try that which sucks because I have to remove the equipment tray. I have the pigtail off the main battery plugging into a XT30 connector on the board with a switch that turns it on and off. With the switch on or off and the XT30 lead disconnnecyed b retracts and brakes still work. The more I think about it though it just doesn’t make sense. The pigtail off of the receiver battery goes through a switch directly into the JST connector

Remember when my unit came with a wire broken. I soldered it back on. Is it possible that was supposed to be removed?

Yep that was it! I removed the red wire from the servo connector and now it only works when the switch is on. Like removing the red wire from A speed controller on an electric to disable the internal BEC.

I think that could be the cause.....looking at this board it look like the same board as the ER-120 the 2 part version which the gear is power by the receiver, that I open because of problems.......I don’t have access to one of mine all 3 are installed I could open one up on Monday....flying tomorrow and sat/sun

great stuff learned something new...

Come on you gotta admit that looked like a broken wire inside the case?

For sure if I had open mine I would have solder that wire as well......

Can you guys confirm that you are using all the recommended control throws including the 8 mm of crow. That just seems like a lot.

4 flights today. Some video below.


Fly’s like it’s on rails. Definitely the right speed for my field because any faster and I just have to fly laps and can’t really do aerobatics. Feels just like an Ultra Flash in a smaller package I can fly in tighter spaces. On the last flight I noticed the trailing link is not fully extending. Not sure if it needs some lubrication or what. Seems to get stuck and need a nudge to drop down.

Good to know! I cut that amount in half because visually it looked like too much but it must need it for elevator compensation because when I drop the flaps, the nose pointed up 45°. Needed a ton of down elevator to compensate

Always alway use take off flap. We don’t have as much as 8mm, but it’s months since I set it up. If I see Mark today will check

Hi Ed,

i used the 20mm take off flap yes. I set the timer to 5 mins and then dropped the landing gear so total flights were 6 1/2. Looked like there was about 1/2” at the front of the tank, which might actually be a little more since the plane sits with a slight nose high attitude. Maybe I could stretch another 30 seconds out of her.

Definitely going to add that nosegear door to help slow down a bit more on landing. Certainly didn’t feel draggy to me like I had expected based on earlier posts about the open ducting.

I feel your pain. I have one that just turned 2 last week and another 6 months old. After we put them to bed is the only time I have to build so even ARFs seem to take a while these days

Hi guys,
i am using 1 6 pin multiplex connector for the 4 wing servos and know how to wire that no problem but any ideas for the retracts and brakes? Would I hang the positives from both retracts and put on 1 pin and do the same for the negatives and then for the brakes do the same? Like the first picture I am attaching? Or separate the negatives like the second pic?

Doesn’t each motor might be different speed, so the gear might not be fully out or in when the output port stop?

I normally used 1 AMP 10 pins connector per side (Ail/Flap Gear/brks) like the one Ultimate jet sell, they are on digi-key website.....
