I got four more flights on my T1 this past weekend, brings the total to 54 flights. The K160 and smoke system are working well. I'm finding myself flying a little more aggressively as I get more comfortable, pushing more throttle, higher speed passes, and much tighter turns. I had a K140 in this jet for the first 20 flights and it flew with authority, however, I'm really liking the little extra thrust of the K160

Spektrum AS3000 setup
I have several flights on my T-1 and now want to add an AS3000 as I already have a Spektrum PowerSafe receiver installed. Does anyone have recommendations for roll, pitch, and yaw gains? Also, any recommendations for nose gear gains and settings? Thanks.

Hi Dansy, I'll have a similar installation to you. Jeti, LG15 maybe GS200 + Electron ...... You are using JP + LG15 retractable landing gear. How do you power LG15? 2s LiPo on directly or through bec.? Your magnets have been removed from the brakes, or you have kept them there. I'm from the Czech Republic, I know my English isn't very good, so I'm sorry. I have to decide what to order retractable landing gear. JP or Electron. I'll be glad if Tom adds his advice. I know he worked out the LG15 setup manual. Thanks guys. ***winter***

Winter,
I'm running the Electron retracts with a GS-200 in my 2.xm T1, I'm running JP retracts (wheels and brakes) in my two 1.7m T1 minis.
I power the GS-200 (with the Electron retracts, wheels, brakes) with a 2S Lipo (no regulator) per the instructions that come with the GS-200.
I power my two LG-15 (with the JP retract, wheels and brakes) units with a 2S LiPo regulated to 7.5 volts. The reason I regulate the power to the LG-15 is not because 8.4volts is too much for the controller, I found that the JP retract controller I have somehow limits the voltage to the retracts at 7.5v. Because I did not realize this initially I hooked up a 2S Lipo with no regulator and burned up two retract motors before I realized what was happening. Now, keep in mind that it did not burn up a motor every time, and it was not the same motor burning up both times, but after loosing the second motor I started to get suspicious and checked the output voltage on the JP retract controller with an unregulated 2S Lipo connected, it read 7.5 volts (battery was fully charged at 8.4v), so that told me that the JP retract controller has some kind of regulator or other voltage drop circuit to limit the output voltage to 7.5v. Since I installed the regulators I've got more than 60 flights between my two 1.7m T1 minis with JP retracts have not had a single motor burn up. BTW, I'm using the little Castle Creations 10A BEC to regulate the voltage to 7.5.
The Electron wheels/brakes do not have retention magnets, but I did remove the magnets from my JP wheels/brakes. If you don't remove the magnets it is almost impossible to get proportional braking and the LG-15 would not be able to function well.
Hope this info helps. -Tom

My JP retracts are operated by the LGC15. I too limit the 2s LiPo voltage to 7.5 VDC using a castle voltage regulator. Electron retracts can take 2s LiPo voltages. JP retracts can not.
I too have removed the retraction brake magnets from the JP retracts. With them in the hub, it takes so much power to the electromagnets to get the disks off the permanent magnets that when they finally move toward the electromagnets, the brakes lock up and the plane dances. Also, the disks themselves get magnetized. Each disk seems to get a varying degrees of magnetism. Consequently, it is difficult to get even braking. That is where the Gyro of the LGC15 comes into play.
Other than the braking issues, also common to my prolink gear on the Ultra Flash, the JP gear has held up well to a 34# dry weight plane, even with a couple large bounces.

Thank you for your very valuable advice. I decided on Electron + GS200. I don't want to change JP for Electron like Dansy after one season.
Dansy, if I understand it, you use one of the two Rx Lion Jeti 3100 mAh to pull out the retractable landing and braking. ***winter***

The Mini's gear looked different to me when we were froggin' around with one. But I have not yet had the displeasure of having to disassemble a Mini's gear. The T-1's original's JP gear has a hub cap over the wheel retaining screw. It is hard to see that it comes off. I did not see that cap until one fell off on the runway in front of me. Removing the cap, makes taking the wheel off a lot easier! The cap is threaded on the wheel. Remove the hub cap. Remove the screw retaining the wheel on the axle. Be carful not to loose the spacer(s) on the axle(s). They are hard to get, and the replacements are not exact. The permanent retaining magnets are just pressed into the hub. Just press them out. I pressed mine out toward the outside of the wheel with a small drill bit or rod. They came out with very light hand pressure. Then put things back together. The brake disk has to be resting on the 3 bolts that keep it aligned. I found that putting the disk on the energized electromagnet with one hole in the disk at the top makes it easy to slip the hub back on with the bolts in the disk's 3 alignment holes. If you do it this way, it is quick and the hub slides right back on with minimal rotation to get the screws in the disk's alignment holes. Then add some locktite to the wheel's retaining screw and install it. Then, screw the hub back on.

Yes I have 2x Li-ion 3100mAh powering my CB200..... I solder a y connection to the harness from #2 to power the retract/Brakes.....I also had a separate small 1100mAh Lipo to power the smoke pump, always installed for the C&G but not always used...

All you need to do is remove the wheel, and split it into 2 removing all the bolts (careful don’t over tight back on).....you will see the magnets...just use a small punch and a light tap and they are gone....

It may sound like a dumb question, but could I wanted to know if anyone able to the batteries in the nose of the plane on the T1. I am using a 160n turbine and trying to figure out where to place everything.
Thanks,

I’m running a K160 and I have two 2S1300 mah batteries in the nose that use for the retracts and brakes. My other batteries are farther back, 2 next to the nose gear well and another next to the tank. Flies and lands nice with this setup but everyone has their own preference. I think the one known regarding CG and the T1 is that it has pretty wide CG range where it will fly ok, you just need to do some testing to find the config that works for your preference. -Tom
