I’ve replaced the broken one with a new model.? This one looks quite different because it’s designed to be a model, not a scale-ish replica.? I personally find it a little more ugly than the Cap 232, but it should fly better.
Maiden today out at PMAC.
Most of this review will be a comparison between the Helios and my previous model, the 2008 Cap 232. You can read a full review of the Cap 232 at that link.
Like the Cap, the build quality and looks of the Helios is absolutely perfect.? I can’t spot any flaws at all, and it goes together like a jigsaw. The main difference in the kits would be the wing assembly. The Cap wing is a one-piece (once it is glued) that fixes to the bottom of the fuselage. The Helios has a two wing pieces that fit onto each side of the fuselage, and are secured by bolts. Both wing types are removable (providing you unplug the servo connections), with the Cap wing being easier to remove, but harder to transport due to size. Although the overall size of these 10-sized planes would mean they would fit in most large car boots (trunks!) with the wing on.
The setup is easy, with the CoG being correct with the receiver at the rear of the battery tray, and the battery hard up against the firewall. You will need servo extension leads all around, with longer leads for the tail servos, which are located near to the tail surfaces for more direct, powerful control.
For my style of flying, the default high-rate setup was a bit much for elevator, with all other controls being fine. On high rates I find the plane stalling easily if you pull up hard, so I’ve reduced the elevator throws to about 80% of recommended, on both high and low rates. If your radio doesn’t have dual-rates, I’d suggest going for 75% of the recommended maximum elevator throw for initial flights.
Maiden flight was easy. Obviously it flies differently to the Cap 232 because of its configuration as a ‘pattern’ flyer, versus a semi-scale plane. The key differences to the Cap would be:
- She takes slightly longer to roll off ground than the Cap
- The Helios appears more directionally stable, if that makes sense. The slight dihedral and low-wing config of the Cap means that it wants to roll out of a bank by itself, but the Helios will hold in whatever bank you put it.
- Knife edge is better (durr!)
- Here’s where I have an issue: the flight envelope of the Helios seems to be smaller than the Cap. I could be wrong, but I really believe the Cap flies slower AND faster. This means that landings are easier (because they are slower) with the Cap. I have real trouble getting the Helios down and stopped in the same space as the Cap.
All other things being equal, I personally prefer the Cap 232. This might just be me, but I prefer the scale look of the Cap, the performance, and the wider flight envelope. Bummer, because I broke mine and replaced it with this. Next time I’ll go back and get a Cap 232. In fact I’m even considering shelving the Helios and replacing it with a Cap airframe until I can afford a second set of running gear.
If you’re choosing between the two models (and I’m guessing between any of the ‘scale’ Hyperion 10e size and the Helios), it comes down to what sort of flying you do.? If you are into precision aerobatics, you’ll probably get more out of the Helios, but if you’re a ‘sport’ flyer who likes models to look slightly realistic, the Cap is a better choice.
