I'm considering downsizing my Slingshot 800x6 tires to 600x6 ... >> Thom - I plan to do the same for my Mark-III, but for a totally different reason. A couple of years ago, I "upgraded" the tires on my Kolb by installing larger 800x6 tires, supplied by New Kolb. I liked the look of the bigger, balloon-ier tires, like most of the Kolbras have. My problem was, they are WAY out of balance. At take off speeds, my instrument panel shakes so violently that I cannot even read my instruments, due to the vibration caused by one (maybe both?) of the 800x6 tires. Luckily, this only lasts for a couple of seconds per takeoff. I took the rim/tire assemblies to an motorcycle shop, in an attempt to get them dynamically balanced. The shop guys told me that 1) yes, they were severely out of balance (I knew that!), and 2) they could NOT balance the tires, as there was inadequate surface mounting area on the rims to apply the stick-on weights. (sighhh ...) Anyone else ever encounter the same problem? Is there a solution, besides chucking these cheap, made-in-China tires and getting some good (expensive), "real airplane" tires like Air Tracs? Thanks for any advice ...

I can`t remember what the temps were at that time. I do remember I was very careful to NOT exceed the Max. temps listed in the Rotax manual. To be honest, I did not enjoy running the 503 tied down at wide open throttle. The FS II kind of shakes around, wanting to be free of it`s bonds. If you do run it tied down, check and recheck and then check again the restraints you are using so nothing lets loose. If yours runs fine and the plugs look good, I would not run it tied down. Just fly it. Hope this helps.

Gotta spend a buck or two to get what you ar e looking for. I experienced the same thing with the Armstrong, Carlisle, and other off ro ad equipment tires. The primary difference between these lawn equipment tires and aircraft tire s is: a. The equipment tires are made to run off road at very low speeds. There fore they are cheaper to manufacture and leave the factory neither trued or balanced. b. Aircraft tires are trued and balanced prior to leaving the factory. No rmally, they do not need additional balancing on our airplanes with slow ta ke off and landing speeds. If we do have to balance a little, it is balanc ing the wheel and hub and not the tire, if the factory did a good job of tr uing and balancing. These tires are also good for 120 mph service. c. An additional benefit from using aircraft tires is their greatly improv ed handling characteristics, especially on pavement. I was impressed at th e difference. Made flying off pavement much more fun. I fly with 800X6 Air Tracs, and have flown my mkIII with 600X6 Air Tracs. Unless you are going to do a lot of off field flying, 600 work fine. John W had just switched back to 600X6's prior to the flight to MV 2008. john h mkIII Titus, AL Anyone else ever encounter the same problem? Is there a solution, besid es chucking these cheap, made-in-China tires and getting some good (expensi ve), "real airplane" tires like Air Tracs? Thanks for any advice .

Did it by guess while spinning them by hand until they did not stop in the same place. excellent results. You can buy those stick on weights at JC Whitney I think. Cheap!
