By comparison, I've noticed that Eflite's smart batteries tend to be on the lighter, smaller size than other equivalent LiPos. I don't know how they do it, packing 100C in some of their batteries and still be smaller and lighter than anything else on the market with much less "C". And cheaper than their non-smart batteries. If you ever use one is an EDF, I'd be interested to know how they perform.

These graphenes tend to be a bit heavier and bigger than a non-graphene battery, so I would guess that both of them total more closely to about just under 7000mah. Since I had to shove one of them under the pilot's seat to balance, I would say that this plane would balance fine in the space allotted with 8000mah, 4s, maybe more.

Never have I taken so long to complete a build. Funny thing about retirement; I've had less time to do things but at least I'm not bored.
Finally got back working on my Twin Otter. Did a first full check of all the avionics (OK - Servos). Discovered two issues with the right elevator servo (yes, I'm using dual servos).
First, I had an intermittent in the Y cable so that had to be replaced.
Second, I noticed the right servo wasn't centering so I thought the servo was going bad so I pulled it. then I tried to remove the push-rod. I was amazed with how much force I needed to pull it out. No wonder the servo wasn't centering. When I looked inside, right where the rear most window is, the push-rod tube makes approximately a 5 or 10 degree bend. The supplied 0.070" push-rod didn't like that bend and started binding in the sheath right around the rearmost window.
All wasn't lost. I replaced the steel rods (two elevators so both push-rods needed to be the same) with my trusted yellow Sullivan push-rods. Yes, I know that is not the ideal fix and a lot of builders hate them but 1) it was the simplest fix and 2) I've been using these rods for years and as long as I had them secured properly, even with gas models, they were very reliable.

Rmawer Thanks for sharing that tip, Rmawer! I too have had good success with Sullivan pushrods in the right places.

We've flown my wife's Twin Otter a couple of times before our move started. This is a really nice flying twin! Both motors are running CCW APC 3-blades with no real ill tendencies. Lands nice and slow too.
This is pre-Nexa, but made at the same factory. Maybe the Nature Air livery will be offered in Nexa at Motion RC.
