Hi Surge
I would be happy to learn how you find your decision of buying that Nimbus 5 years ago from the perspective of those 5 years. Do you still own it? I am curious because I am now facing the same dilemma of low time pilot going for Nimbus 2. If you are somewhere out there I would be glad to hear from you:

Hi piotrm
I still own the Nimbus 2 although I haven't flown it that much due to life and work getting in the way. I'm still happy with the glider. My cautions would mainly be around ground handling and aerotow (I haven't winched it yet). I provided a general update in 2018 if you missed it. You're welcome to ask me specific questions otherwise.
What I would add is:

Rigging:
Try to keep it hangared if possible - I would not recommend rigging it every weekend unless you're young and fit and have time on your hands. I keep mine hangared with the tips off (GA size T hangar) but even that is a bit of a pain since I'm quite particular regarding cleaning and re-greasing all the pins, sockets and L'Hotellier aileron connections at the tip mounting point every time I fly it. These parts are exposed to dirt every time the wing tips are removed. However it is not a difficult chore and I do everything myself using a DIY one man, wing rigger. Total time to rig, clean, DI and tow to the launch point is about 2 hours. Cleaning and rigging the wing tips takes me about an hour.

Take off:
Make sure you start the take off role with full negative flaps to obtain aileron authority early.
When flying empty be ready for the glider to leap off the deck when shifting gently to +4 degrees flaps. Even with trim almost fully forward and my CofG fore of centre, she likes to get airborne very quickly. I'm sure it would not be so when using water ballast but I haven't flown with ballast yet..

Landing:
Go to full negative flaps during roll out else aileron authority degrades very rapidly. I almost ground looped once because I forgot to use negative flaps during roll out and there was a light tail wind.
Don't forget to use landing flaps - they add a significant amount of drag and lift compared with +6 degrees. I landed with approach flaps once (+4 degrees) and I ended up using about 450 meters of runway before I came to a stop - lots of energy to dissipate.

Aerotow:
She's slippery so it's quite easy to get slack in the tow rope in turbulent air even in low tow position with +6 degrees flap. Be ready to use the airbrakes to prevent rope slack.


Hi Surge
thanks for your reply I really apprecite it as I am getting closer and closer to making a final decision about the purchase. I am glad to see that you do not regret your decision, still enjoy the glider and in general I find your words quite reasurring. I am also relieved to see that you did not experience any particularly dangerous situation (except that near ground loop landing maybe). My ultimate aim is exactly the same as you descrbied it starting this thread: medium distance relaxed cross conutry 300-500 km rather than blasting around 200 km/h and fighting in competitions. As for the storage I am also planning to keep her in a hangar, so handling issue should not be much of a problem. Some dust covers are included in the package and that may help to protect pins and sockets from the dirt.

Perhaps one of my biggest concerns are outlandings. Since I am inexperienced (70 hours on gliders, 100 hours on powered planes) I am not planning oulandings any time soon and I guess having 3 airfields almost within the distance of Nimbus2 49 L/D I don't run much risk of a casulal landing. Even if I happend to have one, the area of Poland where I live is covered with large, smooth fields.
Is landing roll really significantly longer than a "regular" club 15-meter like Astir for example? (assuming that landing procedure is executed fawlessly)
Have you ever tried to use tail parachute on landing?

Did you find anything worth emphasizing about handling the ship during the thermalling/cruise?

From other advice on Nimbus 2 which I got I assume that challenges of flying a glider of this kind are lying more in mental areas (concentration/focus/discipline) rather than area of pure flying technique. I guess my experience of PPL pilot may help here (flaps adjustments, engine rpm adjusments on landings/take-offs etc).
Do you know any place where I could find Nimbus 2 pilot operating handbook? I was trying to find in the internet but the best what I found was Mini Nimbus POH.

best regards
Piotr
