Just bought a Hirobo big Lama which is 1/5 ratio.

Anyone has try this lama and can share some setup and experience?

Which servos should be used? The manual suggests use 10kgf.cm,

Which gyro should be used? I am going to try GY701, but can I use Vbar instead?

The most important is - it comes with O.S. BGX-1, but the engine is 20yrs old product!!! What should I change to? Should I change to E-motor or other engine

Thank you so much for any suggestion or help.

Best Regards,

I am nobody, but a RC heli freak

Congratulations! The rotorhead on the Hirobo big Lama is a work of art!

I would vote for electric. Starwood 1/5 Lama is very similar in size and flys well on electric. The OS BGX-1 does not have enough power. Peter Wales put a Jakadofsky turbine in one.

Vbar should be fine.

I agree the OS BGX-1 does not have enought power and would like switching to electrice too.

But which motor should I choose? and any modification needed? How about the gear ratio, all I need to know clearly before goes on.

As there is no room for error for this kind of Vintage Hirobo.

Thank you for the advice.

I vote to go electric on 12S lipo. Do these mechs have a primary and secondary drive, or just clutch to main gear? Post up your final drive ratio, expected head speed and we can suggest a motor for your project...

All helis and planes have an expiration date stamped on them...you only find it after you crash!!
