If you run the gear to the mechanical stop on a battery w/o the controller, the gear motor will burn out. There are current limiters in the controller. If you use too high of a voltage, the gear motors may also burn out. The JP controller I had did have a voltage regulator in it. I ended up junking that controller cause I could never get the brakes working correctly. I replaced the JP with the LGC 15 and had to add a voltage regulator because I use 2S LiPos and the gear motors apparently can't take 2S LiPo voltages..

Are you using the retract controller that came with the gear? I burned out a couple retract motors when I initially started using a Xicoy controller, I’ve found the JP controller limits retract motor voltage to 7.5v, whereas the Xicoy controller was giving it the full 8.4v (using 2S LiPo) and thus I burned up two motors before I figured this out.
Switching out the retract motors is pretty easy and fortunately not that expensive, I keep a couple extra motors in my field box. -Tom

If that is the case then the motor did not fail due to over voltage. I have noticed some inconsistency in the motors, in my first T1 Mini I used a Xicoy LG-15 controller with a 2S LiPo and never had a motor failure in 50+ flights. I setup my next Mini the same way (2S LiPo and Xicoy controller), cycled the gear three times successfully, on the fourth try the left main came down about half way and stopped, after some troubleshooting I determined the retract motor was dead. So, I replaced the motor and cycled the gear a few more times and then the right main failed to retract, failed about half way up. Replaced the motor on that one too, but this got me thinking about the voltage coming from the Xicoy controller. Long story short, I was able to verify that the JP controller regulated voltage at 7.5v, whereas the Xicoy did not regulate the 2S Lipo so the motors were getting 8.4v. So I put a small regulator set at 7.5v in line with my 2S Lipo and everything has been fine until about 2 weeks ago when the left main on one of my Minis would not extend for landing, which then resulted in a belly landing. When I got home I tried the gear again and it worked perfectly, figures! Anyway, I changed out the motor just to be on the safe side. Once you replace that motor I recommend that you cycle the gear a few times to make sure it works consistently. -Tom

With T-1...not so lucky...but my last problem was the trunnions and one motor, after 2 almost full seasons....
The thing is if you see something that the plane doesn’t normally do, in my case sometime one gear wouldn’t do all the way up.....I stop flying that plane and took the gear apart once home and discover the trunnions problems.....got some trunnions and discover the motor also need to be replaced again...cut my loses and order the electron set no controller, I will used the LG15...

I run my LGC 15 at 7.0 VDC via a 10 Amp Castle Creations voltage regulator. They work great. Once you set the LGC 15 up correctly you will love it and the brakes on your plane!

I have 2 of these fine controllers, thinking it was going to solve all my issues....not so much, in my mini JP gear has been solid with that controller but the brakes are still weak...

The only thing I didn’t check is the bolt pattern.....but I can fixed the hole with wood and hysol and drill the new one....I got 3 set of electron on the way LOL...

For the folks ordering Electrons for their Mini, are you ordering the er-30 size? If so, what size struts and wheels are you ordering?
Is anyone already flying the er-30 retracts in a mini?

I have a set of er-30 retracts NIB, so I guess I can just order the preconfigured set for the T1 mini minus the retracts and the controller?

Includes:
2x ER-30eVo main retracts + 1 nose ER-30eVo with Direct servo linked in nose trunion
2x Main Electron legs + 1 nose Electron leg
2x Main wheels with electromagnetic brakes (Electron system) + 1 nose Wheel
1x Electronic control selected

Other than burning out a couple of motors (which was my fault) when switching to a Xicoy controller, I have not had any issues either until a couple of weeks ago when I had to belly land because my left main gear would not extend. It worked perfectly after the belly landing when cycling it, I still cannot figure out why it failed to extend. I have since replaced the motor so we'll see if that addresses the issue. In the meantime, I'm considering switching my two minis to Electrons as I have had really good luck with Electrons on other aircraft.

I got another flight Sunday with no issues except that the landing gear would get hung up on the wheel wells on the way up. When I landed I turned the plane upside down on the stand and noticed the main gear struts were not extending all the way. I'm going to lube strut and try to get them to move more freely. The bigger issue is while I was actuating the gear up and down with the transmitter the nose retract quit working. When I got it home I unplugged the nose retract and powered it up with an external battery and nothing. The main retracts both work with an external battery. Has anyone seen this before? Pacific RC Jets sells the JP motors for the gear for $30 so it won't be a big deal to get another one but it was strange that it happened all of the sudden.
How do I get a replacement?

I have the same problem with the mains after only 20 or so flights. The gear had plenty of clearance in the beginning. Now, the tires are starting to rub in the wheel well because the struts are not extending out 100% after compression. I removed the struts and placed a washer (as a spacer) in the retract unit. That has solved that problem but it now appears I have burned out a motor.

If you have not received your ordered T1 already it's going to cost an additional $200 for UPS shipping or you will have to wait until after the New year. Apparently, EMS is no longer taking large boxes. My mini has been sent back twice.
