Hi Everyone, 



I recently purchased a Kolb MK II with a 503 single carb. It starts and runs great, but I want to check the jetting and temps before I commit to flying. It was previously located at a site 2000 feet lower than I am. My question is what is the best way to secure it to do a full run up? The brakes do not hold it and even if they did, I'm sure it would nose over before I got to full throttle. 

 

Thanks in advance for any help,



Duane

You are right it would nose over.  Also don't trust wheel chalks.  These planes are too light and can jump over.  The best place is through the tail post (steel weld-ment in front of the rudder that attaches the 5" tube).  So your rope goes on ether side of the rudder.  Removing the wings makes the job easier.  



Good luck,

Dave

the best way to secure it to do a full run up?  

  

 Suggestion, tie a rope to the u.c  high up  near the  cage. Both sides and lead the ropes over the tailplanes and back  to whatever fixture you have. Gate post, car fender etc.  A rope over the  fuse tube at the tail fixed to a couple of tethering screws in the ground would  not come amiss either.

I've had good luck using a nylon tow strap I carry  in my Nissan 4wd.  Put a double wrap around the tailwheel strut and hook  one end.  The other end is hooked to the receiver hitch safety chain hook  up on the back of the Nissan.

  

 During full power run up the tail will come off the  ground and maintain a nice level attitude, about the same attitude as  experienced in flight.

Loop an auto tow rope around the tailwheel rod and the other end underneath and around the front wheel of your car (where the weight is). Run up to full power sitting in the cockpit. The tail will lift and the nose will drop, but won't hit the ground.

Thanks everyone for your input. Most appreciated. I'll give them all a try the next opportunity that arises.



Right now we have about a foot of snow or more on the ground and the high was in the single digits today. Not much chance of going anywhere but near the stove.

Racing motorsickle guys have a deadman switch, a kill switch to stop the engine if they should depart from it.



I was just looking at the Youtube video of the pusher-plane at an airshow that was running around with no pilot, mowing people down like crazy.



Wonder if you tied a string to the sparkplug wire or sumthin, or just used a regler deadman switch.

Your best bet is to stay in the plane with your finger on  the kill switch, and the stick pulled back enough to keep the plane steady. That  way if something goes bad, you have a chance of some kind of control. Also if it  was me I would tie to the back of a truck or car if that is all you  have, so that if there is any "fod" in the area it will not scratch  your windshield. I would also make sure that what I was tying it down with  would hold up, and was tied securely.

Duuh. Do you not believe in redundancy? And if you are by yourself, how do you accomplish your tasks that require you to be outside?



I agree with your further points, it just sounds like you didn't unnerstan what I was trying to say.
