Lets start by saying that this is not my first helicopter. I have built and flown Schluters,Concepts,Kalt,X-Cells,Hirobo's,Align,and Jr's. I had got out of the hobby for a few years and had sold most of my helis . I was looking for a low cost 50 size and found the Gohbee 50 , so I ordered one. I started the build and immediately had trouble mounting the motor. It would not fit ! (Yes I left off the washer). The Hyper 50 head hit the inside of the frame . Enter the dremel. I relieved the front portion of the frame and got the motor to slide in. Next problem the bolt holes for the motor were not correct. So a search of the web confirmed that Gohbee knew there was an issue with the bolt holes not correct and instead of repairing the problem they recommend slotting the holes. So I slot the holes and get the motor installed. Instruction state install tank brace. No brace in kit. Email to Gohbee and reply comes back you don't need this part and it is optional. Not listed on there site as option and instructions not updated. Emailed Gohbee they change the website. Next I checked the bolts for loctite and found the spindle bolts have ZERO loctite. All others are ok. I next went through and check the links for tightness. Had to free up a couple this is normal on all kits. However the pitch cage is binding. I had to disassemble the cage and add a shim to straighten. I installed my radio gear and did the setup, off to the field.
I do my prefight and start it. Clutch is hanging . I do a fast burn in and proceed to hover to check out. The heli has a vibration. Set it down clutch will not disengage. Put it back in the vehicle fly my other heli. Disassemble the clutch, damaged also notice the clutch bell does not track true. Jump on the web and order RAPTOR clutch ,flywheel, gear and bell. Replace them all. Recheck head ,blade and tail balance all ok. Recheck setup ok. Next time at the field. Clutch works great. Still have slight vibration tracking off a little . Tried to adjust tracking unable to get correct. Load the heli back in the vehicle. Check head excessive slop in dampners. Ordered the 90 duro Gohbee dampners and at the same time ordered the aluminum blade grips. I already had the aluminum center wich I installed on the new kit. New problem the dampners do not fit the head correctly and even with 1 shim on each side the grips do not tighten as the spindle appears too short. Tried without shims does not fit correctly cannot tighten the spindle and in the process I have damaged the new bearings. Is it worth it? NO ! Would I buy another Gohbee? NO ! I should have spent the extra money and bought a RAPTOR.
