Landing Gear MOD for the E-Flite T-28 Trojan 

I've got a question on the servo reverser. Will they all work? The one I bought (had in the toolkit) seems to function well for my steering servo. It only seems to work the first time plug in a battery fir the retracts. Have you had any issues with the one in the description? I'm planning to get those tomorrow but wanted to check in. Thanks.

I eliminated the servo reverser. I was fixing the original retract and saw how it was put together. I then locate the MotionRC T33 gear. Same size. So i took that apart and put the gear in the original. Actually fairly easy. Take it apart, get the case to close and it must be tight so the wires need to be in fully. Then screwed back together. Checked it before reinstalling and worked perfectly. Just need to pay attention to the setup. Now to fly it when the wind is not 12-15mph. Ping me if you want help.

@@Drones_Eye_View I purchased the servo reverser from Dave’s RC and it works as intended. No unplugging and plugging back in.

@@doncook639 Glad yours worked. I just read his "explanation" and it is not what the Spektrum site says. They do not talk about interference with the rx. Hope it continues to work. My rebuilt OG retract with the T33 nose strut will not have any issues since the electronics are OG.

@@Drones_Eye_View I wish I saw your post about reusing the original servo before I ordered the servo reverser.

Thanks

Could you share how you did this? The Motion one requires a servo reverser and Spektrum recommends not using them with a Y harness like the retracts have.

Figured it out. Not too bad...just need to pay attention to all the details.

You don't know how to hook up the servo reverser apparently.

I think I figured it out. The reverser uses a slight amount of power. I added a 4in servo wire that I can easily disconnect each time I swap a battery. A pain but it likely will work since I can disconnect/reconnect without the ears on the main gear 3-way y holding the reverser in.

​@@sotm6078not true. I have others that work perfectly. Can you give us a hint of your expertise?

I checked with Horizon and here is what I got back from the "bot"Is it possible to increase the output voltage of the AR631 on a channel? The T-28 1.2m has a 3-way y-harness and I need to put a servo reverser on it and it seems the output voltage is a little low when split 3 ways. Virtual Assistant I'm sorry, but it's not possible to increase the output voltage of the AR631 on a channel. The AR631 has a minimum operational voltage of 3.5 volts and a maximum of 9.6 volts. It's also important to note that when using Y-harness or servo extensions with Spektrum equipment, do not use reversing harnesses as it may cause servos to operate erratically or not function at all. Learn More: SPMAR631-Manual-EN.pdf (Page 5) SPMAR631-Manual-EN.pdf (Page 3) ---- This is not a good answer. May need another channel (8 ch Rx?) to do it right.

I purchased the servo reverser from Dave’s RC and it works correctly.

did not effect the CG at all. The part is not much heavier than the original part.

No clue never tried it.

@@bgblindt I’ll give it a try. I just snapped off that pot metal front gear shaft trying to bend it back. Just ordered that freewing T33 front gear assembly you got. So, we’ll see what happens. I’ll post an update if successful. Otherwise I’ll spend $8 and get the servo reverse wire. Great video and thanks for posting it.. very helpful. I liked the tie wrap trick.. I usually use my go-get-em wire that comes with every FreeWing plane.

I have not had a chance to fly it yet
