Dennis, Just one comment, pithy and to the point as requested. Crow hopping is a bad idea, IMHO. You have enough to do on takeoff without adding making an instant transition to landing. How many crow hops have you done in the GA aircraft you've flown? If you're like me, the answer is zero. You say you want to know how to fly your Firestar safely, so fly it. Take off, go around the pattern, set up for landing, land. You won't have any of the muscle memory and sight picture recognition in your first flights so why compound your lack of experience with having to make split second corrections in an abnormal transition from climb to landing. While you're getting prepared this winter I'd recommend you read "Stick and Rudder" with particular attention to the concept of "the spot that does not move" for landing spot aim point recognition, and "The Compleat Taildragger Pilot" by Harvey S. Plourde and his arguments as to why high speed taxiing a taildragger is a dangerous thing to do.

I have yet to fly my 2006 Kolb Firestar that I just purchased. Winter like weather have grounded it until Spring, which is fine by me. I'm a Private Pilot with four hundred hours in mostly Piper Warriors and Cessna 172's 152's 150's. I plan on getting some tail dragger dual time this Spring and then a lot of Crow Hopping in no wind conditions any on a 6000' runway before I take my plane home to my grass strip.
I would like some pointers, but only from 503 Rotax Kolb Firestar pilots with considerable experience in that airplane about flying this airplane safely. Things to do ...things not to do ! Serious and to the point comments only ,Please.

Dennis,
Besides the other good comments, suggest you download a copy of AC90-89A from FAA.gov. Both they and the EAA in their manuals on flight test for homebuilts recommend you do a series of low and high speed taxi tests. This is *not* crow hopping. You slowly add (very small amounts of) power on repeated runs. The idea is to be comfortable with accurately raising the tail and controlling direction with rudder as well as having an idea of what your landing sight picture will look like.. Suggest you follow closely the Advisory Circular through First Flight as this will also have you checking your aircraft condition as well as your piloting practice for First Landing.
The only other point I would reemphasize is general aviation pilots are not ready for how fast these high drag/low inertia airplanes slow down when power is reduced. The remedy is to carry significant power all the way to touchdown. For example, the Zenith CH701 crowd say to use 3000 rpm on the Rotax 912S for the first several hours.

Don't know about the CH701, but my 912S powered MKIII turns about 2600-3000 rpm in a steep approach at idle power. Been so long I don't really remember. ;-(
Your points are good.
I would like to add one thing. After you take off and climb to about 1,000 feet AGL, check your stall speed, then on your first approach keep at least 10-15 mph above this indicated stall speed all the way to the ground. Hard to stall a Kolb and drop one in under those conditions.
There are a lot of bent Kolbs because the pilot did not maintain airspeed above the stall. We have experienced Kolb pilots that have let themselves get into that situation. I like to keep a good cross check on my ASI during approach.
Just got back from Gantt International Airport. Other than a lot of barn dust, carpenter bee and bird crap, several nice sized mud daubers nest, and a couple small bites in the top edge of the right seat back, Miss P'fer (P fer Plane) is good to go. I need to replace the battery, pulled it and kept it charged while I was gone. Must also check the carb float bowls and add some fresh fuel to the tank. I left it stored with some avgas and mogas, plus Marvel Mystery Oil. The MMO seems to do about the same job as Stabil. My Nissan V6 that sat for 3 months cranked right up and ran like it did when I parked it. The Nissan did the same thing last year and the year before that. Have the same sort of luck with Suzuki dirt bike, ATV, lawn tractor, and antique tractors that spend long periods in storage.
Good to be home,

Thanks again,
..........To all who contributed good information and especially the AC90-89A from FAA.gov. . Looks like I'll have it all right in my 'minds eye' when this Spring comes around again.

Dennis,
The only thing I would add to those previous comments is make your first flight a longer one.It takes time to get the feel of something this light.The best place to practice approaches is at altitude,and stall it if you are comfortable enough,or just fly it as slow as you can and maneuver it a bit.You're gonna like it,I think it's Homers"Most fun to fly aircraft".I put 600 hrs on my FS2 and have almost that much on the MK-3 now.
