Finished my PBXL today. Not sure on the weight but seems reasonable. It is the laser cut kit from HSRCM.com (Kevin Harbrecht) and it builds very easily. Where applicable, the parts interlock and it is has been a quick project. I installed a GMS .25, standard servos on all four channels and a 4 oz fuel tank. Would have flown it today but God is watering our lawns. Hope to get it out later this week and I will post a flight report. Below is a picture of the bottom. Thanks Jeff Williams.
