  • in reply to: Taranis image for the V4 tri? #31223

    I made a start on a V3 one when I did the RC explorer logo, but had a hdd failure and lost my progress.. Haven’t been motivated to try since

    in reply to: Everything about the BabyTricopter #31122

    Damn… I know what I’m buying when I get paid…. in 10 days 🙁

    in reply to: X8R with Naze32 frame #30933

    I did mine per the following.

    1. Setup the config like the images in the OP. & Carry out the S.Port inversion mod.
    2. Connect sbus to Naze 32 port 1
    3. Connect the modified S.port wire [just the one wire] to the signal on the Naze32’s port 4
    4. Test in cleanflight.

    Note you may need to configure your radio software to use the correct protocol, but this differs for different firmware.

    Ignore my above :p

    have you tried copying the settings David has in the Triflight setup video


    in reply to: F3FC reports extreme current draw #30575

    Your armed ampers looks a bit wrong 0.6ampers armed at full throttle depropped vs 8ampers while disarmed….

    The info on tuning is here >

    edit: on re-reading the documentation this seems like this may be the wrong method when you have an actual current sensor (first for me, I’ve always done virtual)

    I strap things down to a bench with props to do it, and I wrote a really simple c++ script for this method that can be dropped into an online compiler such as to do the math for you.

    using namespace std;
    int main()
    	double imin;
    	double imax;
    	int tmaxin;
    	cout << "please enter the imin value (Ampers):   ";
    	cin >> imin;
    	cout << "now please enter the imax value (Ampers):   ";
    	cin >> imax;
    	cout << "and finally the raw tmax value:   ";
    	cin >> tmaxin;
    	int tmax = tmaxin -1000;
    	cout << "The Current_Meter_Scale is:   " << (imax-imin)*100000/(tmax + (tmax * tmax /50 )) << endl;
    	cout << "The Current_Meter_offset is:  " << imin * 100 << endl;

    Or if you happen to have MSSQL installed you can use

    DECLARE @imin decimal,@imax decimal, @tmax int
    SET @imin = 2.8 --Ampers
    SET @imax = 34.2 -- Ampers
    SET @tmax = 1000 -- max throttle value - 1000
    SELECT CAST((@imax - @imin) * 100000 / (@tmax +(@tmax * @tmax/50)) as decimal(12,1)) [Current_Meter_Scale]
    , @imin * 100 [Current_Meter_Offset]

    in reply to: Current TriFlight version for F3FC? #29456

    Just checked against my injection moulded one, it’s the same outer dimensions but the interior is a different shape.

    View post on

    You may be able to cut it out, but it’d be awkward to say the least.

    in reply to: Current TriFlight version for F3FC? #29426

    As far as I can tell there are no changes to the dimensions.

    Even if there are I can just reprint mine 🙂

    in reply to: turnigy 9x, open 9x, open tx #29393

    I’m using a modded 9x with a 9Xtreme board running ERSky9X, and have the same thing, I can zero the low side to 999+/-1 but the top end is always 1990+/- 5.

    I gave up its within 2% and as Robert mentioned, If I’m that hard over on the sticks that I need to be hitting the endpoints, then my drone has crashed, because I’m not that good a pilot.

    in reply to: Emax RS2205 motors #29022

    There is no kill like OVERKILL ^^.

    in reply to: extend or desolder cables on LittleBee 30A ESC? #29020

    I rewire, and use a HOT iron 320C normally for desoldering, 300C for soldering [non lead based solder]

    Mixxing lead based solder with the factory stuff is a good way of getting it off too.

    in reply to: Servo broken – fix or replace? #28957

    I resurrected mine the other week, after ordering a pair of the gear kits from BMS directly.
    It was around 12USD shipped, which is less than 1/2 the cost of a full new servo.

    I do wonder if David has plans to stock spare gear sets [would be cool], since the only source I’ve found is BMS themselves.

    in reply to: RCExplorer community PLANE #28898

    We’d have to do a kit bashing but we could use most of the parts. The forward motors could form a straight line all it requires is relocation of the arms perpendicular to the centerline. As far as the forward motor rotation for transition from copter to airplane, that can be handled with a servo and drive gear step up to get 90 degrees of rotation of the forward arms. Easy enough. The rear motor is disabled in forward flight and we can even use the tail servo to stow the motor if we are clever about the shape of the fuselage.

    I think that kind of defeats the object of it being a plane ^^.

    I personally see planes as being two things.
    1. Simple, one motor two servos radio/fpv gear [flight controller/stabilisation optional].
    2. Cheaper, no need to buy three of everything. [This may be offset slightly by manufacturing costs if done in EPP, but still would be less than the Tricopter Kit + electronics].

    That said some components “could” be used like JRach suggested, but it would be better to design an airframe from the ground up rather than an airframe around a pre-existing frame which is designed for a different purpose.

    Nevertheless I did a quick mockup last night of JRach’s Idea, against an approximation of a swept wing aircraft.

    I still feel that this approach puts the COG too far back, as you’d want as much weight forwards as possible.

    A nose heavy plane fly’s like crap, but a Tail heavy plane fly’s only once :p

    in reply to: RCExplorer community PLANE #28861

    Im thinking that we could use the forward swept idea but also use the tricopter frame for the base. Then you already have a pdb and flightcontroller so you can add all the gizmos and fpv you want.

    It’s a novel idea and It could work, it would certainly give you a place to put things, but the COG might suffer a lot.

    @ Flight controller in most cases if designed right you can run an RC plane directly off the RX.
    And if you want Level/GPS/OSD type features, you’d be better off going with APM/PixHawk [mini] GPS as they have much superb support for fixed wing.

    The Naze support is WIP last I saw [FPV labs have a 300+ page thread, tl;dr but it looks like there are bugs in some areas]

    CC3D OpenFlight has some plane support, but not sure how much.

    And of course there are the stand alone stabiliser modules which are just an auto level.

    How about a vtol design with the existing tricopter as a starting point? Or too complicated?

    I like the idea, but it would suit a T-copter design much better, as you’d have the thrust along the direction of travel rather than at 20-30 degrees off centre with David’s Y style.

    You’d have to design a tilt mechanism for the Arm/Motor to tilt and lock at 90 degrees, this would have to be a rigid lock as you’d not want motors that wobble when in a hover, you’d also possibly run into problems with the centre of mass.

    in reply to: Connecting S.BUS to integrated Naze32 board? #28859

    In some cases you can do a small mod to the RX aswell ala – [See Lukas post at the end of page 1]

    This is what I’ve done with my x8r

    In addition you can also use sport with the Naze 32 using softserial and splicing your own rx-tx wire for the sport signal > pins 2/3 on the naze [iirc]

    in reply to: RCExplorer Taranis splash screen #28786

    This should do for the RCexplorer icon, it’s 212×64, I can’t test it because the screen of my 9x is different.
