there are a lot of options out there for redundant power, many of them less expensive than a Mercury SRS, for example, you could just use to LiFe receiver batteries plugged into a Spektrum Power Safe Receiver. Or if all servos are HV, you could use two Lipo batteries, lots of options there. I don’t have a Jeti radio but they have a dual battery setup as well.
With the Mercury on Spektrum, you just plug your four satellites, all servos and two batteries into the Mercury, which simplifies the number of separate components a bit. Mercury is nice, but again it’s pricey. I just bought a Demon Cortex and it was $250, the Mercury SRS is $409, but you get power distribution, so you just have figure out what works best for your situation. The more simple you keep it the better, but jets by their nature can more complex and it’s always to keep safety in mind. -Tom

Zach,
The servos are probably 1250, which are HV. The Mercury can be configured for 6v or 7.4v regulated output so either way you’ll be good. The Mercury can be used with or without GPS, I’m using GPS with all of mine.. With GPS, the gain on the gyro is automatically adjusted for aircraft speed. I’m not sure it’s worth the additional cost or not. Good luck with your build, don’t by be afraid to ask more questions, there is a lot of collective expertise on this thread to help. -Tom

My new Graupner is on it's way and will be here on Monday. I'm tempted to install it on one of my edf jets so I can acclimate myself to its programming prior to using it for the mini t1. Does anyone else here use the Graupner transmitter while flying this airframe? I appreciate all the advice given so far and Tom thank you for all the feedback. For my next trick I need to find someone in Fort Worth to help me get my turbine waiver lol.

[QUOTE=ZachU;12474772]So I had to wait 24 hours to post again and kinda forgot where my brain was yesterday on all of this lol. So one question I have is do you use the gyro during all phases of flight including take off and landing? I've definitely decided on getting the Mercury SRS but reliability came into my mind. Are there failures on these units that you guys know of?

I fly the gyro on for all phases of flight, but I don’t fly in “hold” mode, just rate mode.
Never heard of any failures but it would be best to move that part of the discussion to another forum specifically for the Mercury SRS, you will get more accurate info there and we’ll be better able to keep this forum on the subject of the T1 mini. -Tom

Yeah no worries I thought about that after I replied. Thanks for the information regardless.

Problem with Mercury SRS gyro with 18MZ - Mercury SRS - PowerBox-Systems | Support-Forum
The case of the Mercury says 6-axis on both the real 6-axis and the newer 3-axis systems. Hope this helps.

Anyone have one delivered recently to the states with the new china tariffs? Thought I saw a warming on the pacific jets website saying a possible 25% tariff would be the responsibility of the buyer.

I have another Mini on order, what really sucks is that I already paid for it, so now I don't have any choice but to pay the extra $500 or loose the 2k I already shelled out. I guess it's just a waiting game now to see if the tariffs will actually apply to these jets. If we do have to pay the tariff do we pay PacficRCJets, or would we get a bill from the US Customs Department? -Tom

Finally got to Maiden my Mini today. I flew one 5 minute flight. I used a slight bit more then 1/2 a tank.
Ailerons needed no trim.
Elevators , Flaps up, Elev raised 2 mm above the outboard side where it was level with the tip.
Flaps approach, 1 mm up from the tip
Flaps landing, 1 mm down. this is below the 2 mm up for level flight with no flap.Looks like 3 mm dn from flap up level flight.
Curious if these numbers are close to those flying around the 190 + Balance point.
Plane flew very well, rock solid, stable.
Landing a little faster then I would have liked.Just landed a little beyond where I wanted to.
All in all very easy maiden..
Stan
Easy to see why this is such a popular airplane.

ZachU, the original mercury srs that came out with the 6-axis gyro had some issues only with some units. Make sure you have the 3-axis unit. Here is the link of the issues people were having.
The case of the Mercury says 6-axis on both the real 6-axis and the newer 3-axis systems. Hope this helps.

Wow! Thank you for that link. Really concerning. Not sure how I will proceed after reading that. To keep on topic here I will converse off this thread at a later date. You guys rock for being so helpful. I'm through week 1 of possibly 12, waiting for my jet to arrive lol.

IThanks for the link. I too am having second thoughts about using the Mercury in the smaller T1 mini, the smaller the jet the closer it will be mounted to he turbine, and thus more susceptible to turbine noise. None of my three are the newer version. -Tom

I'm flying this jet with a simple R12 receiver...and one additional R3 on the side of the fuel tank...the mercury PB would be better in something like the T-1 or T-3....keeping it simple and lighter is the key...

Luckily, I have some time to figure this out. I am getting my new Graupner MZ-32 today instead of Monday so I am going to do some reading over the weekend. I looked at some of their telemetry modules and may just go that route with a cortex and some sort of battery redundancy. I like the idea of keeping this jet light and I think I could potentially get a lot of features without the mercury.
Who else on this thread is still running the k70 on the mini T-1? What kind of top end speed are you getting and do you regret not going with a k85?
