Pilot RC 122" Extra 330SC

[Terryscustom]

Now, it seems the planes are looked at as more disposable... just get 'er done!

That's hitting the nail on the head. Not many like to build anymore either. I just wrapped up a design on a plane and have a date with the laser tonight. I'll be running a single on each elevator (MKS 380), two on rudder in tail and two on each aileron. The difference is I have full control of building in hard points and structure to spread out the load of the servo. Also foam core surfaces don't bend like balsa built up

Aint that the truth!!!!

I hear ya'... and I have accepted two per aileron and rudder... that wasn't easy coming off of running 5 back in the day. Here's a shot of my Votec:

Servos have come a long way from the days of the 5945MG's. I have 5, 6, maybe 7 around. They don't have enough torque for todays 50cc and even 30cc planes.

Yeah, from there I went to the 5955s... hell of a servo... and introduced gears that never wore out. Last plane I had before I took a break was outfitted with 8711s... best feel of any servo back then. I had two on the ailerons and 3 on the rudder back then on 122" planes. But then and now still having trouble mentally with one servo on each elevator half. Although my Dalton was that way and I setup my new Yak that way. I'm way happier having two on my new Extra. What can say?

I've seen one radio rep state that power distribution units do nothing and are a waste. That's he's tried them and feels no difference. I ran tests on this way way back in the day and saw a massive difference. 4volt drop vs 1volt drop to my elevator servos in my Carden. Been meaning to setup some tests and make a video. This Futaba 2018sb RX setup on my new plane made it easy to show a test which clearly shows there is a huge difference between what a standard RX can do and what a purpose built power distribution can do:

Wow....my first thought would be something is wrong with that receiver. Why are they equipped with nice dual Deans plugs if they can't handle the pass-thru voltage?

My Futaba 6014HS receivers have never displayed that kind of voltage drop in my 42% Raven.

It is crazy that's it's doing it on a single servo with nothing hooked up to it.

Joe, I almost lost a plane due to that receiver last week. The 7018 has some problems as I am sure you are aware of. I returned mine and the tower rep said they are receiving most of them back that were sold. I've never had the lock problem with other Futaba receivers. In fact I run 14HV servos all the time on my 6014's. But it would be nice to see a test with the 6014 and a power unit. Did you see the disclaimer in the 7018 box? No more than 6HV servo's on it! That's stupid for an 18ch receiver with giant battery cables. Futaba shot their own foot with this one.

I'm going to see where the Futaba RX's go before I decide what to do on my Dalton. I may just go dual receiver or I may go Smart Fly Power Expander. Now that you don't need 14 servos for a 150/170/200 cc plane, you can do without a power distribution unit as long as you go with dual receivers or are using a receiver with power distribution in it (I.E. Spektrum and JR Power Safe).
