Hirobo Vetrol Setup Help
September 17, 2021 09:59AM
HI

I have just aquired an old Hirobo Vertol and need some help with setup on Vbar Neo and Vtouch.

The mechanics has 4 servos mounted in the centre of the model controlling both heads via a mechanical mixing system. the 4 servos are Collective(pitch), Elevator, Aileron and rudder. the swashplates are H1

I need advise on weather i set this up with standard Neo set up or do i need to use the Tandem app and How

I do have pics and manual PDF i can supply but files are 2 big to add here

Many thanks

Well ... it is a H-1 Config - use standard config in NEO as this should have been done in this way ages back when the model was designed. Just watch out for "Tail" pulse and frequency, check all throws, do not exceed physical limits where you might stall.

Example:

Having collective throw set up and also applying elevator by differential collective with too less headspeed/ too short/thin blades ... in forward flight climbout the rear rotor may stall if the angles are too much then. This means ... the model drops down rear, your reaction MUST be lower collective (needs some balls ... definitely ... but i got it manged in flight) a bit and pull elevator also a bit to get the rear rotor out of the stall angle ... this is one of the reasons why i prefer a mix between differential collecitve and "real" elevator in my tandem mixer for 2 swashplates.

Keep note that on such a model yaw is done by differential aileron, also has its limits. Lower all control parts massively here.
