Please don't make any assumption that 35 launches in a glider will help - it didn't for me, and I had hundreds
For what it's worth: when I started taking power lessons, I had ~60 hours in sailplanes and was reasonably current. However, due to a variety of factors (possibly including unusual ineptitude on my part) I didn't solo until I had ~12 hours in Cessnas. Perhaps it was even more ... I don't have my logbook in front of me.
I well remember that my first instructor, who was then chief tow pilot at my glider club, dispensed with ground briefings on the basis that "you're an experienced glider pilot, so you already know all about that". That approach was
not helpful, as his assumptions were usually unwarranted. As robin has already noted, sailplanes and airplanes are similar but not identical, and various aspects of flying the latter will need to be learned from scratch. Don't permit anyone to shortchange your training.
