You are correct! a smaller kite needs more pressure than a larger kite (in the same line). Take Naish's kite manual for reference. They document:
• 3m through 7m kites require a maximum of 8.5 psi or .57 mPa
• 8m through 11m kites require a maximum of 7.5 psi or .51 mPa
• 12m through 15m kites require a maximum of 6.5 psi or .44 mPa
Pressure gauges for your pump are not that expensive. Get one. _________________ Jeff |

If your girlfriend is pumping her kite up to 10 lbs, then you are dating Dwayne "the Rock" Johnson.
I got a fancy Tesla pump, and an actual 8 lbs kinda scares me. As hard as you can pump with a standard pump (around 7 psi) this electric will always put more. (Those little gauges on the pump are worthless). Most any new kite should take 9 lbs, but any defect will make it liable to blow (I hate when that happens!)
I can tell a big difference in performance between 7 and 8 lbs, (the Rally is particularly sensitive to pressure being a flat shape with reduced diameter wingtips)
I'm spoiled by the consistent properly inflated kite the electric gives me, but they are a pain in the ass to maintain, charging, etc., but never a pain in my bad shoulder. That alone made it a good investment for me.
CORRECTION: I see by the above post that I am putting 7.5 in my 10m Rally.That is super rock hard and I doubt the Rock could do it manually. I'm not near as burly as Dyylan, so manually I doubt I hit it to much over 6 psi. Flies kinda crappy at 6, flies like am Eagle @ 7.5 I'm gonna bump it up to 8 and see if its any different.

LOL Dangler!!!! I was really puzzled by the 10psi reference as well... Thanks for clarifying that one for us...
I have one of these little worthless gauges and the issue that I have with it is that I can't seem to know what reading I should trust during the pumping... When I pump (during the strike) the gauge will show a max reading and then settle for a lower reading (when I stop pumping)... So which one to use? The "during the strike" or the "at rest" reading... That's why I don't really use my gauge anymore and was asking about the qualitative test of pressure... bringing the kite at pressure with a gauge but finishing up with a qualitative check...
Any tips welcome. |

Ping tight, rock hard. All by hand and touch.
Those small cheap pump gauges are all over the place and Dangler is spot on about the Ralley's needing to be pumped very tight.
Most of the people I run across in the river who are struggling to relaunch don't have enough air in their kite as they tug and pull on one big wet noodle. |

My Airush says 9PSI on the leading edge and came with a pump and gauge. I usually know without looking when I'm at 9psi because I'm exhausted. Fortunately, the last few months at Sauvies I've been pumping my 14M Blade until exhaustion and now feel like I'm in mid-season form; I feel only moderate hernia, back, knee and general joint pain.
The key for me will be to keep manually pumping throughout the entire year so I stay in shape and don't have hernia/back/knee strain again next spring! Keep on pumping! |

It could be more like 8 psi but thats not really the point. There is no way 6 is enough on big kites, they will fold in half quick especially when they hit the cold water.
And dangler where is that old man strength? I would think at that age you would easily be able to get 8+psi in your kites
But seriously pump that shit up tight. _________________ I heart dangling |

Caution and Boardridingmaui are worth a demo.
-Minus Vote for Wainman: I only like Wainman's pumped up hard.
Old c-kites work fine too. |

sfbomber - you are correct. Caution calls for no more than 6 psi in their kites. (refer the top of page 3)
http://www.cautionkites.com/wp-content/uploads/2013/11/2014_KITE_MANUAL.pdf
I have no idea what I pump mine to. I use the 'flick' test and when it sounds right (high pitch ping) its done. I will say there is a significant difference between almost pumped enough compared to just a few more pumps.
I weigh 145 and have no problem getting enough pressure in my kites.
caps - I will be riding at the south jetty in Newport this weekend if you want to give em a try |

Tolerant of Sub-spec Inflation:
"2015 Rebels work best when inflated to 6psi, but they still work fine at 5 or 4psi. By contrast, many kites on the market these days need 8 or 10 psi to fly correctly."
