MSH Protos Owners Thread

jgoodwin · May 21, 2008, 07:59 AM

We have start this thread for Protos owners to talk about their power setup and also to share their findings, problems, and fixes. People will be running this helicopter on everything from 4s up.

The Protos is a 425mm blade helicopter brought to us by MSH. The guys running MSH brought you Gorilla gear/paddles and other Heliup performance upgrades. The Protos is different in many ways some of which are:

All Belt Driven
Light Weight Composite
One-Way Bearing in Pinion

As much as possible stories and conversations should be centered around the Protos. Vendors are welcome to comment and share, but please no blatant advertisement. I reserve the right to update this post with more guidelines for this thread.

Please share with me in PM any information I might find useful and anything that you think is wrong concerning this thread. I will do my best.

Have fun!

J

Thanks kgfly, Hoverup, RealRaptors, and Corrado

The JR DSxxxx servos are much admired but for me too expensive when there
are so many other good candidates that are significantly cheaper.

It will be good to know the real rotor diameter with the supplied sab´s as a comparison purpose . I have come to my attention how big can a 425 heli be (Logo 400) depend on head span.

So has my Protos

Tried to order 15t pinion but they didn´t have any.
So I´ll propably take one cell off from my 7S A123 packs so I can test it..

Head assembly is 100mm blade bolt center to blade bolt center. Add two 425mm blades and you have a 950mm rotor span. Math verified with metric stick physical measurement.
