I think they should get the radio in order and make it work before they promise any release date. I'm kinda angry now.

I cant believe you have to charge over night for flying the next day !
I always get a spare battery and rotate them in the radio. That way if a battery runs out at the field I just switch batteries and charge the dead one when I get home.

^ Yes I currently do the same. I'll be getting a couple of LiPo packs for the DX8, when the LiPo TX packs are available for a reasonable price and hopefully have a balance lead.

And how do you know that they have not done exactly that? They have waited a long time to provide a release date for the DX8, more than typical products. I think they were indeed getting right before releasing it.

The first charge of a NiMH really needs to be a trickle charge, so that the cells are all leveled off nicely. I ruined an brand new NiMH pack 9 years ago by fast charging it right away, when the cells had different starting votages.

If you cannot stand waiting overnight for the first flight, get the details of the TX pack and have a spare NiMH pack already charged and waiting to go, or a lipo charged and waiting to go.

Historically, radios have always come with overnight chargers as the stock offering. Most modellers have varos charging options if they do not want to wait overnight, once the cells are ready to be fast charged.

Mine will likely get an overnight trickle charge after I bring it home, and a flight the next afternoon.

You only have to take it out if you want to fast charge it....standard industry practice when the charging circuit for the slow charger that comes with the radio is built into the TX.

Any info on battery compartment dimensions?
This should probably fit right?

Thanks Andy
Just a couple more questions, Are the NiMH's in a pack and what kind of connector does it have? Could you still charge the pack externally with a smart charger?
VP

PS I do this alot, I dont realize I am at the end of a page, and then ask a question that might have already been answered on the next page I hadnt seen. It would be nice if there was a "More Posts on next page" flag.

The NiMH's are in a welded pack. It uses the same connector as is in a DX7. You can still charge it externally with a smart charger. Like others said, you would do well to charge it slowly for the first charge.

With a 2S LiPo pack that is slow charged most of the time and slowly discharged all the time and intended to be charged by the charger in the radio, a balance lead is not necessary.

There IS a "more posts" flag. Just above the quick reply box at the bottom of each page. Look on the right side. You see the set of numbers? If the last number is followed by a right arrow > symbol then there are more on the next page.

Andy, would you be so kind and measure the battery compartment dimensions and post them here.
Much obliged!

Thanks again Andy,
I look forward to charging my pack in the DX8 when it arrives. I knew about the page numbers and the > symbol, I just dont always notice it. I have a question about a feature that might not exist, on any radio. How about a 3 position master trim switch, so you could set your trims for 3 different conditions such as no throttle (landing), mid throttle and full throttle. It seems to me setting the trims is always a compromise especially with motor RPM's.
VP
PS You could also have flaps added in the no throttle (landing) position.

When you say "no throttle, mid throttle and full throttle" do you mean three different trim settings so low throttle will give: (1) as slow as possible while maintaining reliable idle, (2) normal idle for maneuvers such as stall turn, and (3) a high idle setting whose purpose isn't obvious to me. Or do you mean controlling throttle with a switch instead of the stick? Just trying to understand what you want to accomplish and how you'd use it.

Will this radio provide all the programming "necessary" for a full-house glider? I am thinking of purchasing this radio, but want to be sure that it can handle the most demanding of sail plane needs. Though I only fly the Radian now (haha), I intend to get my first full house glider shortly after purchasing my next TX (this one??). I want it to be able to last for years...

Thanks in advance,

Okay, the trims would be for all 4 stick channels. You could set all your trims while flying at full throttle, they get stored in the up position of this switch. Now you set all your trims at half throttle, they get stored in the mid position. Finally you set all trims for no or low throttle, like when you are landing, they get stored in the down position of the switch. With this system your trims would be fine tuned to your RPM's which I have found to have a big effect on how a plane needs to be trimmed. For example at WOT my T-34 wants to roll to the left, so you can add right trim. But with no throtttle for landing I dont want any aileron trim so it will come in nice and level.
VP

PS My planes are electric
