Good luck with it all. You'll never forget that first solo. Shouldn't be a reason for going slower in a LongRanger, more stable than an R22 that's for sure (and grown up heliopter controls too).
Take it at a pace you and your instructor are happy with. Better being safe and confident b/c when you look at the seat next to you and it's empty for the first time you realise very quickly it's all up to you!!
