I picked up a Forza 450 combo kit, no TAGS or DMSS receiver. It was quite a nice build and incorporates some good ideas. A well thought out, nicely designed heli.

But -- the canopy is a bit on the small side, and the mounts just plain suck. Access is nearly impossible, and it's difficult to see where they are when trying to pop the canopy on.

Getting the canopy off and on becomes a bit of a chore and the 2200 mah 3s Turnigy/Zippy packs and the canopy just don't get along too well.

Are there any other canopy options for the Forza 450, something with a bit more battery room?

I'm not 100% sure but I think I read somewhere that the Forza 450EX has a bigger canopy. But after getting such a nice deal on the Forza it might seem like a lot to spend...60 bucks! I did see over on HF that the Align 450 Dominator canopy fits pretty good...PMed you a link. I just went through the same issue with the canopy. I was very unhappy at first, no way it needed to be so tight! But I found a thread that helped with the install. Make sure the blades are perpendicular to the boom so the swash links are out of the way. Then holding the canopy by the nose pinch the top and bottom and this will open the back enough to slide it into place. After that it worked ok but was still very hard to remove. So now I put a drop of Tri Flow on the grommets and it works great. After a dozen or so flight it will need another drop as it gets tight...its now just part of my pre-flight! It may seem a little loose at first, just wipe the grommets. I can remove and install the canopy as quick at any heli I own or owned. I had thought about spacing the canopy posts out some to help in the removal. But its just has not been an issue after adding a drop of oil. Like I said I was pretty unhappy the first time I installed the canopy. I even put a small crack in the paint trying to remove it. I also had planned to replace it before even flying it. But now this system works for me, 40-50 flight, no problem!

Link was great. Thanks.

AS well thought out as the Forza 450 is, the canopy and mount system just seems bad. I think the designers just sometimes forget that the canopy has to come off and go on once for each flight, and I'd rather be flying than wrestling with a narrow canopy and hard to see standoffs.

I'll look into the Dominator canopy. It seems the best of both worlds. Decent room for a battery and not $60 a pop.

So would it become a Forzinator if I do that?

@dkshema. The EX canopy is wider and easier to put on. It fits the standard forza 450 without any modifications.

There are heli canopy mounts out there in the market that will also work on the Forza 450 as an option.

Battery size limits for the EX canopy are quite a bit larger than the stock 450. Might well be worth an additional $60.

Forza 450 battery max dimensions:

35 x 105 x 27 mm.

450EX battery max dimensions:

36 x 115 X 32 mm.

1 mm thicker, 10 mm longer, 5 mm wider.

That sounds like just what the doctor ordered.

I broke down and bought the EX canopy. It arrived today. Happy camper here, plenty of room under this canopy for batteries. Still looks good, too.

DIY: More room for battery under stock canopy.
Some will drill another holes "behind" the stock canopy but that won't look good on the Forza 450. So I decided to move the mounting bolts "forward", simply by drilling new holes toward the front.

This will give you about 5 mm which works fine for my normal packs but it wasn't enough for my bigger pack!
So I decided to cut the battery tray in the back as seen below.

First make the cutting lines.

Now use the piece that was just cut off to fill in the gap.

Here is before:

After:

Even the 37x105x30 mm Turnigy A-Spec 2.2 mAH 65-130C still fit under the stock canopy

Wow!...Nice job. Just as long it doesn't interfere with the flight performance I'm down with it!

You can also spend $60 for the roomy 450EX canopy and skip all the trouble above.

There is no real problem with the stock canopy, if you stick to two simple rules.

Firstly, don't ignore the max dimensions in the manual, they are there to tell what the max size is - for instance a Turnigy 2200 40C is inside those dimensions, and guess what fits fine. Why are people trying to get 65-130C batteries into a heli which has a 50a esc??

Secondly, the tightest point of canopy fit, is at the front, therefore only put Velcro under the top third of the battery, but also use a Velcro strap - if you put Velcro on the battery tray nearest the nose, you are effectively trying to install a 'bigger' battery.

Stick to the above and the canopy fits fine, as it was intended to do.

"There is no real problem with the stock canopy"
Yea right! Even with no battery installed, the canopy does not fit right. It's nose is too small inside and even the ESC wires causes problems. Bad design and that is why so many people want to replace it. Including me!!

I have had a Forza 450 since they were released. I have never had a problem with the canopy. Putting an Align canopy on a JR heli makes my skin crawl

Because higher C rated batteries typically will be better than a lower rated C batt in the same application in all aspects. Its like anything, run something to its limit and it will fail faster than something overbuilt for the application. I know since using higher C rated batts progressively as the tech came along I experienced less puffing, more consistent power and longer lasting batteries.

"Why are people trying to get 65-130C batteries into a heli which has a 50a esc??"

The battery discharge rate and the ESC Amp rate are not really the issue, in particular the pack's high discharge rate that is higher than the ESC Amp rating will cause no problems. Most people opt for the higher discharge rate for better control responds especially the throttle. And perhaps more importantly when you come near the end of the flight, the higher discharge pack will still give you more power supply to the ESC. For example, if you used up the 2200 mAh pack down to say 20% which is equal to 440 mAh capacity. So the 20C pack with only 440 mAh capacity left can only give out 20 x 440 = 8800 or 8.8 amp so if your machine hover at 8 amp, it is unlikely that you have anything left to climb out if needed be. On the other side, the 65C pack even with 440 mAh left can still put out 65 x 440 = 28600 or 28.6 amp which is plenty for that.
I learnt this from flying my quad over the water and if I used the lower discharge C rate pack, when the low voltage alarm went off, I may have 30 seconds or less left to fly back to over the ground. But when I use the higher discharge pack, with the same low voltage warning I still have over 1 minutes flying time.
The bigger size & higher price of the higher discharge pack are well worth the money for me.
