The retracts are just fine they are quite strong.
if you fly off grass then you will have to shim up the retract. But if you fly of paved runway then it will work fine as it is. Also if you fly off grass then a three point landing will also work.


After having a great deal of success with the zen 90 i decided to go for the 120 and wasnt dissapointed

also adding two to three ounces of weight at the tail wont affect the CG but it will cure the nose over problems
keep the retracts they look really cool on this model.
