  1. I have come up against that problem. You can only post so many images, then you are kind of out of storage... Its quite debilitating! I am sure Simon or the software has its reasons for limiting image uploads but its not fun for information sharing.
  2. Splendid! I bet that wasn't the first pull Sounds good and healthy... Fingers crossed that it holds up.
  3. 25mph trimmed in // Efficient and safe 35mph trimmed out // more fuel burn, more dynamic recovery 40mph trimms + bar // poring fuel away, hard to hold for long periods The Qubik seems like a reasonably quick wing. I am going to assume you only have "efficiency" to gain in the most part on a hotter wing unless you are cool with spending hours on full bar (very uncommon) I imagine the Kougar 3 will be more efficient trimmed out than your Qubik and you get +7mph Boring XC's for me are anything above 500ft but low and slow has its own set of problems
  4. Ouch, stuck under Bradford CTR. I'm a bit too far west for you. It can be tough to hack it on your own at first, I did two years before people started turning up, now I rarely get the field to myself There are small undocumented clans of flyers dotted around here and there but finding them would be a bit tricky. I stumbled across one yesterday north of Colne... If I can dig our any info on them ill let you know. Flying with others can make life a LOT easier while you are cutting your teeth!
  5. The V5 only uses a CVK 26 so a 30mm would be wasted. V2's are CVK 24 and mine seems to be able to deliver more than the machine can use so I wouldn't worry about it. I think the V5's went to the CVK 26 so they could delete the auto choke/charge coils/battery by using the accelerator pump on the 26 to add fuel (pump the throttle before pull starting) The standard CVK's have a 12v driven wax servo to close the "choke" after a short run time.
  6. I am pretty sure the standard larger GY6 stroke is 57.8mm With yours being a 61.3 stoker (+3.5) that would give you 158.63cc with a standard 57.4mm GY6 piston. I cannot see it having a standard size piston because strokers are expensive and cylinder-piston sets cheap (I got a 63mm cylinder piston kit for £45 // A stroker crank would cost me three times that much) so I'm guessing either 60mm piston (+2.6mm) or a 61mm piston (+3.6mm) The former would give you a 173.32cc (175cc) The latter 179.15cc (180cc) I have heard the v2's referred to as 180cc and 175cc so there may have been some mixing of piston sizes (or even stroker sizes) so there is no way to be sure of piston size until it needs a re-build. Having said that, Ill put money on yours NOT being a 150cc
  7. Pretty sure it will be the 175. It should have a 5mm aluminum spacer between the cylinder and crank case which means it has a stroker crank (+5mm) and you wouldn't go to the trouble and expense of putting a stroker in without putting on a larger cylinder.
  8. its a concern when the stakes are so high. I would like to have a little more weight-shift but my doglegs now form part of my trike structure so I have even less weight shift than you. With the "mid" bars, you have enough weight shift for course corrections so it might be worth trying a set of those if you can get hold of any or build some... Having said that, I have yet to look at the two differing harnesses to see if they are interchangeable, Ill have a look this weekend if its not flyable
  9. Cant open the MOV fie... Mine rattle around like they are quite worn but I am personally unconcerned... As long as the pip pins cant come out I cant see anything exciting happening. I was just looking for some stainless tubing in a more bendable alloy yesterday so I could make another "mid" set for another machine I now have that has the "high" bars like yours. I think my last attempt was with 316 stainless (didn't go well, very tough stuff)... apparently 304 is more malleable so i might give that a go if I can find any with the right dimensions.
  10. Being heavy helps a lot... It takes a lot more finesse to get over a large wing... They are less dynamic though if it all goes tits
  11. Don't sandbag us, those are pretty good... You haven't got stuck only being able to get three in before you lose your timing I'm no expert, I could go over the top when I was free flying a small wing but now I am afraid of snapping one of my bodged up dog-legs... And I'm getting old! They are fun and good practice for exiting any wild departures from normal flight. If you initiate very late (in order to loop or go BIG) and you don't have enough energy, be prepared to momentarily bury both breaks at or around the apex or your lines will go slack and you will lose a large portion of your wing (I'm not 100% sure of the exact timing sat hear behind my keyboard so take that for what it is) Its best to "inch" your way into getting bigger, that way if there are any errors you will likely only lose a wing tip. I think everyone ought to be able to get 50% of their wing under the horizon, 50% is not unreasonably risky and it gives a good feel and confidence in how to bleed off asymmetric energy which is the most likely departure we would see in rowdy air.
  12. Some images and a writeup of you rebuild adventure would be cool. Popular engine like that... It would be nice to get a closer look at its guts
