Topic: FVK Bandit setup Help Please

Hi peeps

Can anyone recommened possible setups for the FVK Bandit, I am hoping to get mine next week or the week after and in the meantime want to get some help on what to put in it.

I am after having a medium power setup, maybe around the 400w to 600w area, but with a view to increasing this up to around 750W or possibly more once I am more used to it.

If anyone knows what motors, ESC's, props and li-po's I could use to obtain these setups then your help is very appreciated.

Many thanks in advance. 

Don't be so gay

1Kw budget setup mentioned at the start of the vid:-

FVK Bandit ~ 1kW

Nice idea, but the motor is only rated at 5S and he is running it at 6S, I dont fancy chaning the motor on a regular basis, it would be ok if we could get those motors in the Uk I guess 

Anyone else with some setup ideas?

These are the same as the Turnigy stuff.
At those prices it doesn't matter if you cook it!!
I should think at 5c you could prop up for a pretty peppy performance.
If you want some quality give Puffin Models a call?

Thats the exact vid I was looking at for my next home grown mini 'F5B' just last week!!!

loads of cheap outrunners available - search the lecky forums here and RCG's for more info.

post your findings...

4S and 14x9 looking good from other reports so far???

Check out the thread on RCgroups http://www.rcgroups.com/forums/showthread.php?t=1050611

The Turnigy motors have got a good rep, I'm using the 800kv version, but the 900kv and 1100kv are also widely used with good results. Trick is to keep motor runs short if putting lots of amps through it, and make sure your batteries are up to the job. There's a vid in that thread of someone using the 1100kv motor which pulls about 82a-goes like s**t off a shovel.  I've run a 14x10 on the 800kv, using 2x 4s 2200 batts. I currently favour a 11x10, 1 x  4s pack, mid 40a for 600 something watts. The 14x10 (13x11 is another option) was pushing my batts a bit so propped down for now. And with 2 x 4s I need a bit more space to land as it comes in a bit quick sometimes (flying field is a bit small, wind needs to be a northerly really).

The fuse has bags of room for batteries.  That vid convinced me to try the Turnigy brand and for £20 delivered it's the dogs baubles.

If you're still not convinced after reading the above thread, try a Hyperion 3025 series (I think it's mentioned in the thread too). Turnigy esc's are a good, reasonabaly priced esc, I use the 80a Plush which was @£35 with Turnigy 4s lipo's (<£20 ea DELIVERED). Hobbyking is a good retailer, just keep each parcel under 1kg, all of mine slipped past customs un-noticed that way. Suppo 100a esc's have also been used.

Scorpion motors were tried too, Robotbirds do both the Hyperion and Scorpion but you'll need to research which is favoured, I'm a cheap skate and wouldn't spend £50 on a motor when the £20 do the job for my 'occasional' flying. S'pose it depends on your budget.  More money=more choices. Hacker and a gearbox would be a good reliable choice apparently.

I always wonder why these questions aren't asked in the electric section?

In that section they would probably ask a similar question! Why is it not appropriate in here?

i have found 'Hotlining' and required equipment doesn't get much feedback in the lecky forum.

Is it another case for seperating the forum into sub sections (scale gliders for example) or just having a big melting pot?

I dunno, I thought they'd be the experts an all. I've always had a good response in there. Anyway, carry on chaps, I'm sure to learn something useful for my next Birdy.

I always wonder why these questions aren't asked in the electric section?

I suppose because 'technically' it's a glider 

Nope. It has a motor on so 'technically' it ain't. 

But it spends more time gliding than under power, hence the name, ''Motor Glider''. 

It has a glider design and planform...

I reckon one has to be young and have eagle eyes to fly those things .

It's an organisational thing. Or a late onset of OCD.  

Heck even I was flying my PSS P51 'motor glider' today about 5 sessions in the tiny park next to the house eaxh time running 3 batteries flat. A great day for hotair ballooning or sticking a motor on the EGPro.

Here's a pic of my PSS MotorGlider:

EEK!! It's A merry can! You could have at least chosen something British!  
BTW, sorry to disillusion you, but it's not a PSS motor glider as I suspect it spends most of it's time under power, ergo it's simply an electric powered (scale  ) model.  

Is it not an 'e-soarer'...? 

glides, goes fast, all fun....

D'Oh! Busted! Me, not the plane. It glides like a brick but is a lifesaver in weather like today.

So does anyone have anything useful to say on this thread regarding hotliner setups?? Or is it that no one knows what will work 

 

 

 

 

Maybe try the electric section? There were a couple of posts and links to a big RCG thread and also to suppliers earlier in the thread.

Dunno Steve, I'm watch with interest, I've got a Bandit and bought it ages ago with the recommended Hacker motor and gearbox, the ESC was for nicads though. I haven't flown it yet but may just resurrect it based on your experience, you will keep us informed wont you?

J

Yes John, I will let everyone know what I evetually use in it.

So far it "looks" like this motor 35-48 HobbyKing

A 60A ESC from GiantFish

A 4S 2700MAH 25C pack from the fish

And then prop it to around a max of 60A peak.

A Hitec HS-82MG on the elevator and 2 x Hitec HS-125MG's in the wings.

This is my current plan, though I have NO IDEA, that wattage this setup will be, but if its not enough I can always increase the cells to 5 and change the motor and ESC, and again, if that somehow isnt enough, there is always a 6S option, lol 

Alternatively you could try one of these, http://www.brchobbies.co.uk/?page=shop&item=671  This motor will enable you use a larger prop (13" x 6.5") on 4s than the Hobbyking motor you quoted and will therefore have more grunt (over 800 Watts (in)). I would use an 75-80A ESC with this motor.  Good luck in your quest.

4S and 60A is going to give you a tad under 900W isn't it? It'll be different in flight but that does sound impressive...

Cheers Gumball, may well give that one a try

Well I have to say, thats more than I was aiming for originally, however, I will give it a go and see what happens

Before you do Steve, just be aware that the motor shaft will need reversing because as supplied the motor is a rear mount. You'll need a front mount in the Bandit.
 If you don't feel confident to do that, you could get this one instead....  http://robotbirds.com/catalog/product_info.php?products_id=5455  and data sheet.........  http://robotbirds.co.uk/catalog/images/emaxgt.htm

Have you got a wattmeter?
If so you can play with prop sizes to ensure you don't cook it. Then you have a guide for prop size/pitch to make it perform how you want.

If not you really need one or I foresee magic smoke imminent!

Yup, no problem turning shafts around, had many an eletric, usually shockies and the like so am used to turning those around

Yup, have a watt meter and thats what I was planning on doing to to get the right prop combo for this setup, no idea where to start with props, so might start at an 11 x 7 and work up from there till I reach around 60A 

Thanks guys, really useful stuff coming out here

Personally, I'd go for

a, Bigger batteries- http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=9463&Product_Name=Turnigy_4000mAh_4S_20C_Lipo_Pack  or http://www.hobbycity.com/hobbycity/store/uh_viewItem.asp?idProduct=9467&Product_Name=Turnigy_3600mAh_4S_20C_Lipo_Pack    Both are reasonabaly priced, current exchange rate puts them at the £20 mark each + p&p ($10=£6.50)

b, Bigger esc- It's just better to go bigger, it'll stay cooler and if you want to over amp your motor (it's not that bad in short bursts, ask the F5b boys) it'll cope. Like I previously mentioned, 1 guy is pulling 82a from the 1100kv motor (rated 54a) but short bursts only (about 5-6s). Found the vid for you

FVK Bandit

You'll prob find a 13x9 Aeronaut gets you close to the stated max amps for that motor. A 14x10 was low 60's (soz, long time since I tested mine) 13x11 mid 50's, 11x10 low 40's and a 13x7 mid 30's. Sukalu recommended the 11x8 but on a 5s for the 800kv motor. Told me I would't want for much more. When my 4s are dead I may try 5s out and see. Make sure you use decent servo's, MG's are best for when you slam on those spoilerons to slow her down, you don't want plastic gears stripping 

I don't know how much room the Bandit for the motor but the E-Max 2826-06 dimensions in the BRC site are given as 30mm x 26mm which can't be correct. Despite what's said by BRC about clones, I think it's the same motor as this from GC, which is 38mm x 48mm.

 

Guys

Got my Bandit in the post on Friday and had a quick look at it and a read through of the intructions. From what I can make out where it says about cutting a multiplex plug in half for the ailerons it implies that the wings are kept as two halves and only joined when you put it together at the field, is this correct?? 

Leading on from that, has anyone ever glued the wings together permanently, using epoxy or whatever? 

Yet again, any help appreciated 

Guys

Got my Bandit in the post on Friday ...

Hope you don't mind me asking, but where did you get if from and how much was it? I tried Brian Anderson but he's out of stock.

Thanks

I got mine from Brian, at the time he had 2 in stock, one of which I purchased. This was around 10 or 11 days ago now I believe from memory they are around £130 plus P&P of about £10  

Anyone knows about the wings??? 

Re. the wings, there's a build-log here.....

If anyone lese is thinng about getting one, get in touch with Brain (see FVK.de for his e-mail). He's waiting to collect a couple more orders before he ships some from Europe 

Go on, you know you want one.......

Turnigy 35/48 1100Kv motor
Turnigy Plush 80A ESC
Turnigy 4S 4000 li-po
Aeronaut 12.5x9 blades.

Somewhere between 1100 and 1200 watts.  Does it for me!

Here is a review of the Bandit posted some time ago but still worth a read:

http://www.rcgroups.com/forums/showthread.php?t=231614

I found it very helpful when I built my Bandit about 5 years ago which is still going strong.

My set up is the same as in the review except it has been converted to lipos.

Not too far removed from what I have eventuall bought for it...


Setup will be as follows

Motor
Model: TR35-48-A
Input Voltage : 7.4V~18.5V (2~5S Li-po)
Kv : 1100 rpm/V within 10%
Dimensions : 35mm X 55mm

80A Castle Creations ESC, max peak 120A

2700Mah 30c 4S Li-po, so a constant supply of 81A peak at around 108A

Prop, Aeronaut folding carbon, somewhere between 12 x 8 to 13 x 8 I would think, but testing needed. Even though the motor is rated at a mere 55A-60A, peak burst will be nearer to 80-90A  . I dont care if I cook it as its the cheapest part of the entire setup  Power is estimated to be used in 3 - 5 second bursts.

Wing servos will be Hitec HS125MG slimlines

Elevator servo, Hitec HS82MG

3A UBEC as the ESC will only handle 3S when using BEC mode, add to the safety too.

Hopefully will be getting it all together over the next couple of weeks or so, apparetnly it should have enough power to hand launch without a run and chuck

Steve,

I'd have a look at the Turnigy ESC that I'm using.  It has a built-in SBEC (what ever that is), and has been 100% solid.  Less than £40 too.......

No need to run when launching; just a firm shove will do!

Well I done a quick test of the motor, esc, prop and li-po last night, prop used Aeronaut 13 x 8 folding.

The results....

Its pulling around 72 amps peak on a 4s pack fully charged. My watt meter wouldn't read it as it went over 1KW, but best guess is around 1100 to 1200 watts. Things do get warm very fast, but if i stick to 3 second bursts all should be good 

I dug out the servo holes too, not a nice job, I looked like I was in one of those shake up snow globes 

Will try and fit the servo linings later, maybe even the wing servos if I can round to it. 

You gunna video your antics
I love watching these things tearing skywards

It might be worth going down an inch in pitch and/or diameter as a bit of insurance until you can reliably measure how many Amps are being consumed. The up side is that the motor will unload a bit in the air, but if it's getting warm quickly it sounds like the motor is running way beyond it's peak efficiency and max rating.

Taking your advice, I think I will drop it down to a 13 x 7 for the initial runs and see how it goes 

It also helps if you do a bit of gliding. Not something I do a lot of TBH but it will help.
