I got to play on ski's for one day and now its melting fast. The lakes around here are full over overflow now. While Danny is throwing money at the cub..... Yesterday I did some testing on the sensinich 82" ground adjust prop (first flight was with my borer prop for baseline). I was able to dial it in and went from a 17.5 second take off run to 9 second take off and have the same indicated cruise speed. Time to climb from 1k to 2k holding 75 mph indicated dropped 12 seconds. instant acceleration and you loose 13 pounds off the nose.... buddy was testing in his 180 HP cub and got similar if not even better numbers than I did. Helped sell 4 props yesterday for him! I look at most of the reports and call BS on them... outrageous claims that can't be true. Till we tested and recorded the numbers. I was blown away!
For the sled I LOVE my 2015 bearcat 570. Wide track that will pull one hell of a load and its aircooled so when you pulling said load or running along packed trails pulling a groomer at a whopping 5-7 MPH it doesn't overheat. To top it off its the most comfortable and easiest riding sled out there and the older I get the more comfort comes into play. I can do 300+ mile day and I am not worn out or sore.
I can send you some drawing and pictures of what I have been building up here for groomers. The key to these is the cheap electric winch on them so when you start getting bogged down you can hit the button and lift the front of it and it will just ride on the compaction pan and you don't really know its back there. I have also made them manually adjustable and while that works great on a trail it really sucks if you suddenly hit a soft spot and it starts eating a bit too much or if you want to get off the trail to turn around etc. All in all, your looking at a day to cut and weld it out and about 300-400 in materials, but it will serve you for MANY years to come and is fairly light weight to boot. It is 4' wide and 6' long on the ground plus the length of the tongue ( I think that's around 2.5').
Every time they ask me if I want a receipt I say nope, ignorance is bliss. When I fist started my Avid rebuild I made a spreadsheet to track costs and hours. I quickly decided that was not something I wanted a record of and deleted it.
Are they kinked? If they are not kinked, the best way I have found to straighten them is a block of wood with the tube radius routered in it and a hammer. YouTube had some old school FAA videos showing this. I straightened up some pretty nasty bends quickly and easily.
The covering will hold it all together. I think its best that you seal up the strut before you put the wood fairing on. Mine were not sealed up and the tubes rusted out really bad where the wood was holding moisture against them.
