For the price these are very hard to beat. They are in stock and local.

They fit very well and the CG is spot on. Dont be fooled in to higher discharge C packs, these packs are very well made and are more then capable for the stock power system.

the reason i recommended higher C packs is for future use as well. if you stick with stock then 25C are fine. but once you decide to upgrade to bigger motors and esc, 25C will make your system heat up a lot depending on motor and prop choice. if i had known any better when i started out i would have gotten batts that have a future with non-stock as well.

Prop upgrade for float conversion

I have been told that in order to use floats, I'd have to upgrade the prop. The only problem is, no one can tell me which one. Does anyone know which one I need? Still running the stock motor. Thank you in advance.

If your gonna be around for a while, I suggest these. Yes, they are not cheap. But a $100 investment for 2 is all you'll ever need. Charge at hi amps in 10 minutes and last forever.

I too did cheap lipos too. Had many. Better bang for the buck IMO.

Robj, you should know better...

Of course I expected that Danny, I only have about 2000 flights on my T-28 although I don't fly it as much as I use to.
OK then, so you have 2000 flights on the T28.
This only means that you should really know better than to give the advise that you dish out.

Tripple checking is a great idea, providing you actually know how to spot a problem.
A novice can hardly be expected to recognize what can later become a problem that will cause a crash.

As for flying in tight places full of obstacles, again it is a case that with your 2000 flights you've forgotten that a novice will have a much harder time negotiating the obstacles.

Bottom line is that the majority of people don't have 2000 flights on a particular model , perhaps) and sadly most novices will end up a first flight with a planed that waws not checked by an experienced pilot with the sour feelings that comes when you prang a nice new plane.

Even a stable and fun plane like the T28 needs enough altitude to pull out of a loop, especially if in a dive with full throttle, a person with 2000 fights will know that and put the plane high enough, a novice may even go into that loop unintentionally and/or too low.

Sadly novices dont come with 2000 flights, they need to start and a prang in the first flight or two is not something that will help them in the hobby.

Once again, I am sure that you are a great pilot but not everyone is so, most of us mere mortals need a helping hand when getting started.

Brgds,

Danny

Floats look cool on the T-28. Don't tell anybody, but I had done a great sin. I fly from snow, more than half of the year. And grass and rough ground the rest.
I have put an extra gear mounting plate near the leading edge of the wing. And mounted my fiber glass skis on them, making the T-28 a taildragger.
Will test it on Monday. I am working making it steerable too. Because of the conditions we fly in here up North, trikes causes lot of problems. Trikes are best on hard surface. We also put larger wheels on the model on the short season without snow.
I am not the first in our club, who have done this, and it looks like it works fine.

In this season of the year, with cold weather, and lot of snow. It's more easy to fly lighter models. They float on the top of the hard frozen snow. Many use floats too. It's hard climate here but we still want to fly. Now it's clear calm ice cold days. With the cold creeping in from Sibir i Russia. Problem is to keep the batteries warm over time.

Anyone got some tips for mounting an 808 cam on the Trojan? I want to be able to mount it without damaging the foam. I have the D lens so was thinking it would be nice to mount on the horizontal stab to get the side of the plane in view. Any tips on mounting?

Those Hyperion battery's above look great for a real Hot Rod build. If you need to draw > 40 amps those look like a good choice.

Im a big fan of the Gens Ace (not the Eco series) too. And just to a slightly lesser extent the Sky Lipo packs. Its just a pita the ones you want are almost never in stock.

Keep hearing way too many complain about the Zippys.

The HobbyPeople packs are surprisingly good. Not just from my experience by several who I fly with love them. They just last and keep performing well. Its nice they are local and in stock. I picked up a set of 4, 2200's when they where on sale for $10/pack a few months back.

All battery's regardless of price will fade and fail eventually. So for me, the goal is to find a battery that will perform the job your asking of it (discharge C with some head room) with out costing too much. The stock PZ Power 480 and E-Flight 30 Amp ESC will never stress an honestly rated 20C 2200mAh pack (44 Amps continuous discharge). Even with the the E-Flight Power 10 or the Turnigy G10 your well under the C rating. Once you bump up to a Power 15 or bigger (not the PZ Power 15 as its really closer to a Power 10) they you will want to spend more $ for a 30/35C 2200mAh pack.

When I fly I use all 4 of my pack's in rotation and immediately get them on the charger after a flight. 4 packs is just enough to keep me going with out having to wait for a pack to charge. I use a Hitec X2-400 and charge 2 packs at 2.2 Amps (1C). So for me Id rather have 4 packs for the price of that single Hyperion listed above.

Ill look in to all those batterys. Thank you. One thing tho. I got one of those battery buzzers that was set to 3.7v. My battery only has about 10 flights on it, when I trottle all the way up for little bit my cell 1 drops to 3.64. Even 1 minute into flight. If I stay below 1/2 throttle its fine the whole flight. After the flight the cells are at about 3.85v. Is my battery bad?
