06-17-2005, 05:37 PM
I was wondering, where can i buy my next set of main blades for my nexus, I've been looking at G.H. and can't seem to find the ones for a Nexus.
Any help would be greatly apreciated. Part number, etc...

You could convert to a longer boom and run 550's.
Try a caliber boom...
the caliber boom is 623mm long. The Nexus is 600mm.
This will get you from 530's to 550's.
As far as fit goes, the slot for the front in both booms are the same, however the hole to index the tail rotor case is different. You have 2 options at the tail end.
1) Drill and file new holes in the end of the caliber boom to match the tail rotor case.
2) Remove the plastic ridge in the tail case. However, this means the tail case will be more suceptable to slipping on the boom, and could rotate or pull out.
For the correct drive wire, cut down a C60 part # H6046 to 632mm . This is stock length 609mm + 23mm from the longer boom.
Your on your own for changing the tail pitch control wire. Now would be a good time to put the rudder servo on the tail boom. Another caliber part can be put to use here, part #CA3052

you have given my some food for thaught.
Only one question remains, will my Tunder tiger .34 be strong enough to handle the diameter difference, or is there a difference to really talk about when it comes to touque and pitch etc...
Has anyone ever tryed to glue the tube in place, or even drill and put a small rivet on one side, so as to not interfere with the iner drive wire to the tail?
also would it help my gyro, if i put the tail servo closer to the tail?

Your engine will turn the rotors at a lower rpm with less pitch to provide lift, there should be no problem flying with the 550's and any typical 30 class engine.
I have in the past used a small screw to secure the boom to the mainframes, but on a belt driven heli. Just be careful where you install the screw, and maybe add ca to the threads. Make sure the screw end doesnt protrude to the inside very far at all...maybe 2mm.
Moving the tail servo to the boom will only affect the c/g, the gyro will not work differently as long as your linkage was free (not binding) prior to the servo relocation.
