I posted this in the sailplane forum but am not getting any response. Is it OK if I post this question here, as it is a beginner's question? If it is not OK please remove it.
I was given a Tower Hobbies Vista 2 Meter Sailplane ARF as a late birthday gift

Will I be able to save money and use the Dynaflite Up-Start?

Or will I need this Dynaflite Standard Hi-Start?
http://www3.towerhobbies.com/cgi-bin...?&I=LXE635&P=V
The upstart says it can be used on Sailplanes up to 72” and the sailplane I want is 78 1/2”
Is that a big enough difference to matter?
