Mines still going strong after 3 1/2 years. Did not beef up the landing gear blocks at all, still good as new. However have replaced the legs, as mentioned above they bend backwards, so you have to bend them forewards or the plane will nose over. After too much of this they break.
I went with flaps, and the do make a difference. Mixed in 20% down to retrim the plane though for them.
Power is a 91 FX, really pulls it around!
. Surprisingly smooth flyer, taught me a lot.
