Thx JNorton for the reply
Yes most of my posts have been in the begginers forum but this is my 20'th plane (and all 20 still intact ) and ive been flying for a year

, soo far froma beginner im used to flying warbirds but i saw this ShoeString at a show and was on a look out for a plane with speed which flew nice and from all the comments in here about the ShoeString it just had to be that
Im thinking of getting a OS91 Four Stroke to put in, will that fit in with no problems ?
