i wouldn't use a 60 on it. i had a 60 on mine, she broke ground got to about 6 ft and dropped like a rock. busted the wing up pretty good. after i rebuilt the wing and almost mortgaged the house to cover it, i put an Irvine 150 in the nose. the 150 flies it real nice. of course i reinforced the firewall and fiberglassed the entire nose so the 150 doesn't rip it off.
i also converted mine to a tail dragger as the nose gear would bend all the time, even just taxiing around. i also had to beef up the main gear after the conversion as that was now bending. i used B&B landing gear support bolts with a 7/32 music wire. no problems with ground handling now.
she need alot of rudder as the ailerons do not seem to be too effective. she wants to crab to the left all the time, i am currently working on trying to figure that one out.
it is alot of fun to fly and she lands like a dream (nice and easy)but takeoffs can be an experience. seems she wants to drop the right wing after breaking ground. if you are ready for it and use alot of rudder you can deal with it.
i didn't build mine but if i did i would drill a lot of lightening holes in the fuse. with the 150 on it mine weighs 16 lbs. didn't think that was too bad considering the size but then again i din't have a manual to know what the finished weight should be.
i included a picture of bg bertha after the repairs and tail conversion, but the beefing of the main gear came after the picture was taken. good luck
