I don't know why people feel they have to cut the canopy away....if you want to, then go ahead....but you don't have to. I've been flying mine on a variety of batteries, mostly purchased from Hobby King, and with a few good ones from Horizon Hobby. Most are in the 20C range (that's all you really need for this model to have a good time...), some are in the 25C range, and some are in the 30C range. I really like the Zippy brand batteries, and Turnigy are pretty good too. I've had the most success with 20C batteries I bought from Horizon Hobby. I have alot of batteries. I've also standardized on XT-60 connectors for my fleet...everything has 'em except the the new Archer and my trusty old Super Cub...

If you absolutely feel like you have to mod away, then by all means, mod away. I'm just saying you don't have to....I personally like the handy little pocket Parkzone designed into the plane....it holds them in nicely and you don't need velcro.

Durafly...it's a real gem, and I've had it for about 9 months.

Oh man JustWingIt...you need some battery storage options.

I have about that many batteries too. I store them in Pyrex baking casserole dishes from Walmart or anywhere else in case of a short and fire. Your wall would go into blazes in a hurry if one of those batteries short circuited.

One of my buddies stores his in a BBQ pit...another stores his in an ammo box and puts that in his fireplace (that I assume he never uses).

Just an idea...

Holy batteries Batman!! How do you use all of them? I'd be too tired charging them.

I have about 5 or 6 each of different C ratings; from 20-25C for the T-28, all the way to 35-40C for the Skyraider and Freewing Focke-Wulf as that's all I really need. I fly my models scale and that's all the juice I need. I also have quite a few 1300's for my Wildcat, but they're all 20C because that's all she needs. Clearly I don't fly through them all in one sitting....not enough time !

I usually bring about 5 or 6 2200's and 5-6 1300's and feed the little beasts. If you think about it, that's good for at least 2 hours at my little field....plenty for me. When I drive down to the drylake (30 mins each way) then I'll take a few more batteries and stay a little longer. Having that many batteries gives you options...

Thanks Russ for your concern, but batteries don't just spontaneously explode; usually you have to drop them, leave them unbalanced, etc. I take really good care of my batteries. Handle them properly, don't puff 'em, keep 'em balanced, etc. I'll probably eventually put them in a ammo can as they're fire-proof and I have plenty of 'em around where I work...

Off to fly the T-28 before work !

John,

Please don't take me as an alarmist but sometimes they do.

Of the very few lipo accidents that I have personally witnessed, most have involved either charging accidents (wrong polarities connected) or crashes, or just flown too hard to LVC and beyond.

I had one about 6 months ago that came unsoldered from the connector and touched wires and it puffed, smoked, then spewed out fire for about 20 seconds. If it hadn't been in the pyrex, it would have certainly at least caught my table on fire.

By the way John, love those A-10 pics on your Blog!

My buddy, who has a similar stack like that has said many times " Dude, I've been doing this for years and have never had an issue". 2 weeks ago, while trimming flashing off a control horn, dropped a razor which hit a lipo and instantly, it ignited like a rocket engine!

He was able to get it out of his home before catching it on fire but took sacrificial hand burns.

It's all fun & games, 'till you burn your house down!

Like I said...they don't just spontaneously explode...some form of human intervention is usually required !

Thanks for the comments about the little "airshow"...sometimes I wonder why I've stayed in for so long, and sometimes I know why...days when you can watch and observe destruction like that are why I've stayed in for so long! It's a blast....literally !

Cheers my friend,
John

I made a metal container for charging my LiPos. I'll have to post pics sometime. I had a scary accident last year where one went up in flames in my bedroom. Luckily I reacted quickly and shoved it in my (plastic) trashcan next to my desk and ran it outside. I now have a metal trashcan in my bedroom .

The ammo box is a neat idea. I'm gonna try to find one online.

Army/Navy surplus outlets anywhere...in Houston we have lots of 'em so easy to find for $10 to $30 depending on sizes. You can also order online from many of the surplus stores but shipping is going to be expensive!

Beware of the cold!

So once it arrives, I'll get it setup and admire it while I fly it on the sim till spring. But next winter, once I have a bunch of batteries under my belt, winter flying is doable.

Tell me, how realistic is the Phoenix Trojan t28d compared to the real thing?

Again thanks for the advise.
Yeah, I'd recommend waiting for warmer weather as well. I just got my T-28 in early January and you really have to watch out in below zero weather The tape that holds down the horizontal stabilizer (as well as the cosmetic tape that covers the reinforcing spar in the wing) loses its tack in the cold. I ended up nearly crashing after the tape stiffened and the pushrod pushed the stabilizer out of alignment. I "fixed" this with a dab of glue to hold it in place, but since then I've had two other incidents with the cold. One of them was losing the cosmetic tape I mentioned above (in a dive...it just rattled the plane and flew off) and the other was losing about 1/2 of the horizontal stabilizer control surface in flight. One hard turn and "snap!" It is a testament to the plane that it was still partially controllable in that state and I was able to land safely.
