Mike,
  All of the JTM stuff is top notch composite work... You will enjoy the quality,.
The only issues I have heard about is with the strength of the retracts/struts.
You may want to be a bit soft on the landings, i've heard tarmac or hard surfaces with short grass work best..

Thanks for the feedback, is it the retracts/struts or the mounting areas for them that are suspect? I have not gone for there retracts or struts, I am going to use the E-Flight electric retracts to keep the clutter down.

The kits are heavy for their size, the L39 no exception, and they put a lot of pressure on the retract side plates, the metal was very soft and bent easily.

The eflite are generally excellent as long as you pick ones big enough to handle the 4+ kilos or so AUW of the JTM models. My Hawk is 4.4kg and I have bent 2 sets of retracts, Andy and I are in the middle of discussions with the retract factory pushing them to make hardened side plates.

Thanks for the heads up, I am converting mine to turbine use, so landing weight will be less than an EDF version, could make all the difference to the E-Flight retracts.

Be sure to post up some photos of your setup and how the retracts go, am very interested to hear if they handle the weight ok.

If you look over on the "Jets" forum you will see a few converted Habu's and others that are using the E-Flight retracts successfully, you can also find the conversion thread I am putting together under "Jet Teng L39 for P20"
