Tri-Trooper 750mm Build

[FSMCA]

I have heard ecalc is quite tough on co-axial performance drop relative to flat setups and that you might get better flight times than calculated as a result.

I do notice when I change it to flat, I gain 4-5 min.

Would you go with SunnySky X4112S 400KV again?  When running them through ecalc, they are the second best I have seen to the X5 on paper, but it says they might run too hot.

It';s a little early to say.

They arrived 5 mins ago ::)

I am now wondering if it';s worth using nylon mesh cable sleeving between the motors and ESCs.

Given that all the wires run inside a carbon tube I';m tempted to just braid them together and go without the sleeving. It will save a little weight and build time and make replacing motors in the future easier.

What have other';s done with their Tri-Trooper motor wires?

Edit - after dry fitting the parts i managed to nick a silicon motor wire. I had to put a bit of heatshrink over the nick. After that i decided to just cable sleeve the lot of them and I';m glad I did because they feel a lot tougher as a result.

Now I have to work out the right lengths for staggered ESC placement in the tube arms. I can';t see that being at all difficult or going horribly wrong...

Motors cable sleeved to staggered lengths (needs a final trim) and ESCs de-bullet connected and flashed with the latest BLHeli.

If anyone has suggestions on the best BLHeli settings for large low KV motors on 6 cells I';m all ears

ESC attached to the motor and motor mount, correctly sized to fit down the tub arms.

Still lots of work to do, but;

Looks nice, any tips on putting the sleeve on?  Whenever I try, it just frays and frays, despite trying to melt the ends with a lighter.

Get several different sizes so you have a range to choose from. It';s harder if you try to use a piece that';s too narrow for the wire.

I';ve got the pixhawk installed on top and the motors wired in, spinning the right way and responding to the pixhawk when i use the motor test function.

I just need a receiver and some LiPos and some props and then i can try flying it (next month).

Like the LED';s on the motor mounts  - what are they? Where can you get em?

One suggestion - I swapped the stock bottom / battery plate Spyder came with for Tarot rail mounts - a bit more flxible and better / more mounting options

[teslahed]

Almost ready for flight testing now. I am just waiting on a couple of small but important parts like the receiver and a power cable.

I still haven';t chosen or bought a gimbal for it but I';ll do that next month after I know it flies OK.

The weight of the frame + motors, ESCs, power wiring and the flight controller and all electronics is 2350 grams.

This does not include the battery (1150 grams approx), the gimbal (yet to be decided) or the payload (350 grams of camera).

Still worked out lighter than i thought it would so I';m quite happy with this.

Assuming I fly with a 10,000mAh 6 cell that weighs 1189 grams;

I';ve just finished adding FPV gear including a full OSD hooked up to the pixhawk. Next flight will involve the FPV helmet

I';ve also added a 2.4ghz telemetry link via an FrSky telemetry adapter i made using an arduino nano and this open source firmware;

And it seems to work pretty well. I just need to sort the programming on the Taranis to give sensible voice alerts now.

That looks the business and I have just noticed it has props top and bottom how does that work.
