Slingshot Rev Inverting ?

[trouty]

I have also posted this over on kite forum but would really appreciate some help here thanks.

 

Hi guys i rode a friends new 9m 2009 Rev (not 2010) on Friday in very gusty 30 knt plus wind.

 

I really liked the kite it felt smooth with good range and an awesome bar (i fly Ions) The kite seemed to have really good hang time and i was very inpressed with the build quality.

 

I had no problems with this kite but my friend who is a beginner somehow kept getting the kite to invert ?

 

Has anyone seen or heard of this problem before and if so is there a cure for it ?

 

We flew the kite on settings to give maximum depower and i did notice the more we cleated off at the depower cleat the worse is seemed to make the inverting ie: slacker lrear lines.

 

In the hands of an experinced kiter the kite flew and behaved very well but in the hands of a beginner the inverting did'nt look good. I can only think that very fast and uneccessary bar movements caused the kite to oversheet and invert in the gusty winds we had ???

The kite was probably flying near the top of its wind range at times altho im 12 stone did not find myself overpowered at all.

 

Would be nice to know if this is a known problem.

 

many thanks

Was it pumped up nice and hard?

i know my old storm mk1 6m used to do it if you depowered too much.

i think its just because the kite become unstable on the front lines and just fly them selves over.

I had one on demo last year, it inverted on me and gave me a right fright, but the boys from slingshot said i was wrong, they said it did not invert, impossible they said,

so your mate is wrong, it never inverted, it can't do such a thing.

simpleessss.

never had any problems with the rev, but i remeber colin said that.

 

it seems that this is isolated to the 9m and the 9m only.

 

the 7m is as stable as a rock in silly silly wind,

 

i have seen riders on the 9 in 35s in spain and the kite was again stable as a rock, but perhaps you just gotta make sure its pump up sffiecently. i dont like saying that, i think a kite should need to be pumped to a certain psi, but in general the rev is bullet proof,

Yeah i have a 9m Rev 2 been flying it all summer and love it... It has dropped out of the sky a couple of times with me for no apparent reason even in stable winds and usually when its sitting just off 12 oclock. I couldnt really find a reasonable explanation as to why this happened. forunatly i was able to run backwards and regain tension in the front lines before the kite it the ground. I have seen this kinda thing happen with many kites. I wouldnt let this put me off the rev as its a fantastic kite.

did it happen when you leant down to pick up a board, with the bar out and the kite at 12?

[fatbobfossil]

9M is more prone to it than other sizes. Pump it to 9Psi will solve the problem.

would i be wrong in saying this is the same problem as ppl have found with the bandit dos?? i may well be wrong witout research, but i think it was the rev?

[dhole1412]

nope.. my bad.. it was the north evo that has the same problem as the bandit dos.. apologies!!

[kiteingcolin]

it was the 9 mtr that went funny on me, but the pressure might have been the problem, not sure as pressure was not a watch point when it first came out,

 

it is now with moden designs, a pressure gauge is now so important, my nemesis kites are blown up to 12 psi every time, good job they come with a gauge as 12 psi is an effort, best not to try blowing one to that pressure after a big breakfast.

the human gauge is its 12psi when you need to lift both feet off the ground to push the handle down between your knees,

Been flying revs for some time now and never once close to inverting. It is not a known problem for the rev. Probably possible with very bad trimming plus beginner pilot.

I prefer my kites to be set up with knots for maximum power to perhaps the middle knot on the centre lines (I like the kits to turn fast) - I don't think you'll need to go any further than the middle knots on all four lines. The add a tad of depower on the cleat as conditiond dictate.

 

Oh and also pump up to super hard - ignore guages (in the end thay always rust up & fail), you won't burst it

 

They are grunty kites.

Different kind of kite, but this is exactly what happened to me on Saturday with a 13m kite in lightish winds. Not done that for months, felt like a right numpty!

[trouty]

thanks for your replies people.

 

I think he only pumped the kite upto 6 psi but as he is learning the kite is taking some very hard landings on water and beach.

 

I am amazed it didnt burst !!

 

I;ll get him to put more air in next time and see how we get on. Also move lines to a more central point (thanks)

 

Great build quality and a really nice kite to fly and jump with id have one for sure

 

thanks again
