I have a Saito 100 that needs a home and am having some problems deciding what plane. I already did some searching here but most recommendations are for 3D planes, which I already have 2 of, a Funtana and a Morris Su-do-koi. I found a Vector Flight Extra that looks good, and although it will do some 3D, I like the look of the Extras. I am also considering the 60 size H9 P51. The concern I have there is that I fly on a grass field and am concerned about the retracts holding up. How strong are these retracts? Are they strong or will I be looking at major repairs from one rough landing? Any other suggestions are welcomed and appreciated. Thanks in advance.
