X-UAV Mini Talon

[MarkLloyd]

Anyone put a meatier motor in the MT?   I'm putting together a second  plane and am looking at a spare ntm 35-36 1800kv motor that's sat here.   I've used them in the funjet,  venturi,  Z2.....    Plenty of umph on 4s.  It's going to have a 8ah bat up front and will fit ok.    Thoughts much appreciated.

I think my numbers on current draw to maintain level flight were a little high.  I did a 50 minute flight on Tuesday evening, and stayed below 500 metres for the whole flight.  I managed to cover almost 42km, using just 4.1Ah.  Level flight was maintained at around 4.5Amps.

I even managed to get around during 3.42km out on my Jeti 2.4ghz radio.. ..

I'm not sure I'd want a heavier motor and battery combo really.  Whilst it might give  ore umph, I think the loss in efficiency and low speed handling would be detrimental.  That said, there's nothing wrong with trying it!

I just ordered a 1038kv Leopard motor for my Mini Talon build.....Now I need to find a nice 8 x 4 or 8 x 5 Prop for it....They look nice quality in the photos with a prop hub too..

Tempted to get another Storm AP.... £79 on E-Bay....UK supplier...

4S Lipo....but...which one...?

I'm using an APC 8x4.  It works well.

As for a battery, I use 4s 5000mAh 25C packs, and they are performing great.  They are nothing fancy, just turnigy packs from hobbyking.  I bought them at the beginning of last year for a multirotor, so they have maybe around 100 cycles on them now.  these are the ones, but I got them from the UK warehouse...

Cheers Andy.....A 5000mah sounds good....not too heavy.....:)

:vulture:

[Andy Sayle]

It seems to be great.  As I said, I managed a 41 and a bit km flight using just over 4000mAh, so it is obviously working sort of okay!

41kms on a 5amp Lipo....mental...lol....I was thinking of keeping it light in the interest of an easier launch anyway...The little Leopard motor with an 8 inch prop sounds good to me, I dont want anything bigger doing a hand launch...Cant imagine me needing any more range than that anyway...so why load it up..? I know some people have put 10amp Lipos in them, must be an exciting launch with a hot landing speed....no thanks....:)

I was surprised too!  I was expecting to be able to do around 25km or so, but the thing kept going!  I would normally push these batteries to use an indicated 4500mAh, and land then, so I reckon with a bit of care, and not doing any full throttle antics, I might be able to hit up to 50km.

The other plus point about keeping it light, is that launching is dead easy.  A nice firm chuck, and it is away.  I actually think it would probably carry a second 5Ah pack in parallel without too much fuss, perhaps making it land a bit quicker, and the launch a bit more interesting....

...Agree....I dont really want the fuss of a bungee, so an easy launch appeals...10kms per amp...thats easy to remember...I suppose a nice streamlined Camera pod would also be of benefit....A 3D printer would be handy for that, then again, carved blue foam would also work...hmmm....:)

:vulture:

[Andy Sayle]

I haven't bothered with a camera pod.  I've just got a fixed mounted fpv cam on the lower front ply ledge of the standard nose contraption thing, then a sticky gopro mount on the top deck.  The long flight was done with a GoPro Session attached.  I'll get round to editing the video off it at the weekend hopefully....

After trying out the SS2216 1250KV motor with a 8x4 I can say its super efficient which is good. Cruises at 3 - 3.5 amps so from a 8AH lipo its got the potential for crazy ranges. However I found the climb rate was abysmal at best. Trying to get to the clouds was a laborious task and I would happily sacrifice a little cruise for a lot better climb.

[Andy Sayle]

That would be a cracking setup for out and back type missions though!  On my setup, I find it takes me around 12 minutes to get to 3.2km altitude.

In theory, of course, I can't condone flying to that sort of altitude......  ;)

Glad I'm not the only one thats found that!

I tried my 10a 4s multistar in my MT.

launching was easy, I put the mfd in launch mode and threw it lol.

Landing speed increased a fair bit, and broke my landing gear.
But it was just that, landing gear only.
Couldn't take off with it.

Once the airspeed wears off, it then drops down like a stone.
The impressive glide is non existent.

Performance over duration wins for me.
I got the MT for speed and fun (probably why my motors keep burning out,) and my skywalker for duration.

I now use 5800mah 4s compacts in it.

35xx motor shouldn't be much of an issue with the right prop and battery setup.

My Talon has a 8000mah 4s Multistar and pan and tilt with a Runcam, she is 1787grams and has no issues at all on hand launch, just a level throw and off she goes. Landing speed is around the 25mph mark  :P
