Bandit ARF - Durostruts or Pro Link
Just wondered what peoples opinions were on the best legs for the Bandit ARF.
Any problems with using the Pro Link struts? I assume that they fit the MkII, with gear doors, without modification?
What are the advantages (if any) of sticking with the standard BVM struts?

RE: Bandit ARF - Durostruts or Pro Link
Trailing legs do have a tendency to bounce the model, this is because there is no rebound damper!
The spring tension increases as the legs are loaded up, and of course they want to unload immediately (Land as lightly as possible)!
The up side is they are friendlier to the airframe if you are flying off of grass!
I did see some trailing legs with dampers on them at Jet Power this year, but I can’t remember the supplier!

RE: Bandit ARF - Durostruts or Pro Link
It would be interesting to see a barf II fitted with trailing links to see how they fit.
I bought the gear door upgrade for my original barf but found the gear door will hit the bottom of the strut when using the prolinks (it isn't a problem with the durostruts). It may well be possible to make work with a bit of thought but I've not fitted the kit yet due to lack of time to think it through and retain the prolinks. I fly off grass and would rather use them.

RE: Bandit ARF - Durostruts or Pro Link
Trailing link struts would require some rework to the wheel well and wheel well door and hinge.
The Bandit ARF Mk I and Mk II wheel wells are not designed to fit trailing link struts, regardless of brand.
The wheel wells are designed to fit the Duro Strut only.
You would need to open the wheel well in the aft direction in order to accomodate the new wheel position, which would cause you to lose the aft side of the wheel well door frame that is molded into the wing skin. The door fits flush with the lower skin as designed.
You might also have to reposition the wheel well door aft hinge so the tire would not interfere with its operation.
Duro Struts work very well on this airframe. We have flown the prototype Mk II from grass (FJ 2011, Great American Jet Rally) and have enciountered no problems.

RE: Bandit ARF - Durostruts or Pro Link
It is a bit of a surprise to hear that the Pro Link struts don't fit out-of-the-box as they are sold as 'BVM approved' and 'No modification necessary'.
The question is answered though and it sounds like Durostruts are the way to go.
Thanks,

RE: Bandit ARF - Durostruts or Pro Link
There you go, words of wisdom!
From the people who are using them, the originals fit the model with no modification, and seem to work without any issues off of grass! They look better as well!

I know that we show an early Bandit ARF with them, but modification is required, especially if you have already ordered the wheel well door package. They are "BVM Approved"
With a BobCat or KingCat, there is no airframe modification required as the gear retracts aft in both cases.
Right...Duro Struts are included in the Bandit ARF landing gear option, and are the way to go.

RE: Bandit ARF - Durostruts or Pro Link
Harley,
So the duro struts that come with landing gear package are fine off the grass??? I was going to order the pro links from BVM for the MKll Bandit, but I dont really want to make modifications, especially if the regular struts work well off grass..
Any one have any pics of the mods to put those in?? Curious, would just like to how much is actually involved

RE: Bandit ARF - Durostruts or Pro Link
After having switched to prolinks, I wouldn't go back. And, yes there is a little trimming on the wheel well that has to be done, but nothing that I couldn't live with.
I don't have the MK 2 BARF, but after having MANY, MANY flights on a BARF (and still probably less than Harley and others here) there is nothing like NEVER having to touch flex plates again.
I can't remember the last time I had to change flex plates, as a matter of fact. With duro struts, I would just be doing some routine maintenance and such, going over my BARF and then be surprised to see a broken/cracked flex plate.

RE: Bandit ARF - Durostruts or Pro Link
I flew my Ultra Bandit from the grass at Florida Jets 2011....the condition of the field was awful, but the Duro Struts performed flawlessly.
We also flew the prototype Bandit ARF Mk II there, and it worked out perfectly....multiple flights, and no damage at all.
We sometimes fly at a couple of grass fields here in central Florida, and have not had any problems with the Duro Struts at all. BV even practiced for Top Gun this year with his 80" F-86 from grass to get accustomed to how it would handle the grass at Top Gun. He has flown his F-100 from the same field as well.
I have flown my KingCat from the grass, with no flexplate or landing gear damage.

RE: Bandit ARF - Durostruts or Pro Link
I think if you want to do the door package I would stick with dueostruts . If you think you will be flying off a rough field double the rear plate. I have been having a problem with rough field operations cracking the rear plates. So now I doubled them. No problem unless I go way off road I know the wing will crack. Dan Avilla

RE: Bandit ARF - Durostruts or Pro Link
I have a light weight Classic Balsa Bandit, and a heavy metal Super Comp Bandit. Both have Duro struts as I didn't want the hassel fitting well doors with prolinks. (I believe it can be done with a bit of work.)
I used to break flex plates reasonably often, but now that I have the Bandit landing technique sorted, haven't had to change one out in ages.
I also considered doubling the rear flex plates a few years back, and even made up he correct spacers to suit, but in the end I chickened out and kept the stock set up. (I was too frighetened of ripping out the internal wing structure.) Flex plates are designed to break!!
My opinion only. I know other guys like, and have sucess with the pro links and/or stiffer flex plates.

RE: Bandit ARF - Durostruts or Pro Link
There is a change incorporated in the Bandit ARF Mk II which strengthens the main gear wing skin area.
Two end grain balsa blocks (in each wing) are installed during construction to keep a broken flex plate from damaging the wing skin.
Without the new blocks, a broken flex plate would allow the landing gear unit to move upward, sometimes damaging the upper wing skin.
The addition of the end grain balsa block limits this type of damage.
This change can be incorporated in the Mk I airframe very easily.
See the attached photos.
