The Xicoy You have I assumed is the pro version......because the regular, which I also have, I don’t think has adjustment either

LOL, it never donned on me to use the door sequencer in the red box. Just used a spare channel on my radio

I tried on my T-1 but i couldn’t do any adjustments, used the cb200 with a sequencer and mix...

I’m not sure if it’s the pro version or not, but the cutoff amperage is adjustable. I have the same unit that I bought from Electron for the retracts in my bigger T-One but the Electron version is preset and not adjustable by the user. I like this unit because all the door servos are adjustable, and the integrated gyro helps keeps the aircraft straight when braking hard.

The red controller for the jp retracts has no adjustments other then brake force as far as I could figure out. The 2 door outputs one is regular and the other is reversed. I had to move to the inner hole adjust the rod and Dremel a little clearance on the hinges so the door could open more. Be careful, the first time I plugged it in it ripped the whole plywood plate mount out.

Tip22v

How do you adjust brake force? Is each brake individually adjustable?

Your end points adjust brake force. No directional force though. I wish

Ok, so your adjusting the brakes in the radio via end points?......I have mine at -100 and +40 as well, but to me that mean the brake controller has no adjustment just my radio doing it.....I haven’t done any taxing yet lot of snow here....I might increase or decrease that value still

They are adjustable if you put them on a slider then you add as much or as little as you like. Or you can put them on a the accelerometers of a Jeti TX like I do and just tilt your TX to stop. I set two jets like that so far and love it. But back to your original question no there isn’t any adjustments you can make to the control box.

Tip22v

The accelerometer trick sounds cool but my DX18 does not have that feature. I don’t have a problem with brake force, I just mix in brakes to down elevator, works fine for me. Where I have problems is adjusting the left and right brake force do that they brake eveningly. I’m operating from a 300’ asphalt strip and if I don’t get my landing just right I sometimes have to hit the brakes hard to stay on the runway.

I used a slider with a less then 100% max....so they don’t lock.....normally around 40% max....on pavement

I went out yesterday to maiden my T-one mini. I got everything ready (fueled up, range check, control check, etc.) then I decided to cycle the gear one more time just to make sure the retracts were working properly, the gear went up, but only one of the main gear came down. I fiddled with it a bit at the field but there was definitely something wrong so I decided to forego the maiden (I don't like "fixing" things at the field, especially before a maiden flight). I got home and spent a couple hours troubleshooting, I eliminated the controller by changing the plugs around, I eliminated the retract itself because when I pulled it out of the wing it cycled perfectly every time, that left only one possibility - some kind of binding. Upon close inspection of the wheel well I found that there was a slight protrusion on the fuselage side of where the wing connects to the fuselage that was causing the strut to bind when the wheel is retracted. Using my trusty dremel I was able to trim off 1/16" and now the wheel retracts and extends reliably. I'm glad I decided to do one more check of the landing gear, that would have not been good to get the gear up in flight and then not be able to extend one of the main gear. I would highly recommend that those of you who have not yet flown your mini to check this area of the wheel well, I cycled my gear at least a dozen times before I got to the field and found this problem. Now I have to wait for another decent day of weather to do the maiden. In the meantime, I was able to get a photo of my two T-Ones side by side.

Just about done and took it out for a lap up and down the driveway today. Will likely be a while before the maiden here up North. The pics of the Xicoy show the AUW with fuel. At this weight you can see it drives the CG pretty far toward. My reference point to add/remove weight is between the slots for the canopy hooks. Big difference from it balancing at 200mm with just the UAT full. I can understand how it may feel nosy heavy in flight and may adjust accordingly prior to the maiden.

AUW with fuel

Tip22v

Can you post a picture of your AUW (including front, left, right weights)? I want to compare my weights against yours...Thx.

VK96

Without fuel?

Tip22v

Sorry about that. Yes, without fuel in the main tank.

VK96

Main tank empty...UAT full. What do you show?

Tip22v

My numbers are much higher, I have a little fuel in the main tank (about 1/4"). Not sure why mine is so much heavier, I'm using a 2100 3S Life for the turbine, and two Fromeco 2600 2S Li-Ions for the radio/retracts/brakes. The powerbox unit weights a few oz but is certainly not a pound and half. I'm using Savox 1250 servos on the ailerons, elevator and nose steering. I'm using MKS HV747 servos on the flaps and rudder. I'm also using the UAT that PCRC sells, it looks like it holds at least 6oz so maybe thats where I'm putting on some significant extra weight.

Perhaps where I'm most concerned is how the CG is calculated. Based on my measurements using the same computer my CG is about 13mm aft of yours, even though we both think we're going for 200mm. Regardless of our respective CG points it clear based on my lower nose weight and higher main wheel weights that mine is definitely more tail heavy than yours and this concerns me. I would really like to compare these same weights against someone who has flown theirs to see how they compare.

VK96

Thanks to the unseasonably warm weather here in NH I was able to get a couple flights in yesterday. VERY impressed...wide flight envelope, and super stable. Felt like I had 100 flights on it already. Minimal trim needed, but it did take nose-down with flaps extended. Great everyday jet!

VK96

Got a chance to grab some measurements after the first couple of flights;
Dry weight (UAT full)-16.51lbs
CG(measured with xicoy meter and checked with fingers- 209mm
Ailerons-18mm 60% Expo (Jeti)
Elevator-19mm 35% Expo
Rudder-35mm (but more throw available) 30% Expo

Flaps T/O- 25mm
Flaps LDG- 70mm

Elevator comp;
Flaps Up- 1/2mm Nose Up
Flaps T/O- 0mm
Flaps LDG-4mm Nose Down

1/2 flaps for takeoff on grass?

Tip22v

Maidened mine today. I only flew it one flight. I have it setup identical to VK96 above except my CG is 200 as opposed to 209. Everything went well except mine felt very tail heavy, almost got her into a spin at one point just cruising around. In its current configuration my mini does not fly anywhere near as well as my bigger T-1. I'm going to play with the CG a bit more for next flights...

VK96

How does your elevator trim compare to the values I posted? I feel like I could bring my CG even further aft. It pulls slightly in knife edge, and requires a bit more "nose down" input while inverted than I'd like. It flies great where it's at, but I prefer my planes to be as neutral as possible.

Edit- For anyone looking at the pictures and values I posted previously the batteries we're moved after the pics were posted. For the 209mm CG I have the 2200 LiFe battery over the nose gear, and the two 1500 mAh RX packs on top of the fuel tank.

Tip22v

I've got my two 2600 mah Fromeco LI-ion batteries and my 2100 mah Life battery mounted to the rear top of the fuel tank, which results in my CG located on the aft side of the wing tube, which is about 200mm from where the wing attaches to the fuselage. Are you measuring your 209 where the wing attaches to the fuselage or where the wing molds into the fuselage?
