Helifreak Exclusive - Pic's of Trex500 in USA!

I don't know what went back into it... Andy took the pack with him to Vegas. The pack was not broke in and had been sitting unused for 2 months at least! It needed to be cycled a few times for sure. It may have even gone bad sitting. I have not talked to Andy since last weekend so I don't have a status on that pack.

Sorry - I was referring to the Align videos. 6S 2500mAH has 63 Watts, 6S 2200mAH has only 55 (~80% of the capacity). In theory, that's a difference between 7 minutes and 5.6 minutes. Jason's video on 6S was using 6S 2100 - even less capacity.

[rotary65]

Dug up some different data from the first Align videos that reveals the difference. On 6S, the 4.5 minute flight time is with a headspeed of only 2650 RPM, while the 8 minute flight times are likely with a headspeed of ~2100 RPM. This is much less than what Andy quoted on the video (3000 and 2600) and certainly goes a long way towards explaining the discrepancy.

It's all still a lot of speculation. It'll be nice when we have production Trex 500s in our hands so we can share our own data/experiences.

[Finless]

Not sure I believe that post after seeing Andy fly it with over 2600 HS!!! For sure that data isn't accurate and no telling where the data there originated! i can tell you seeing it myself NO WAY 2100 head speed.

You cant believe everything you read on a forum man.... Including stuff I tell you though I usually speak from SEEING it live rather than posting info that may have com through many mouths! I try to be honest and not post conjecture as much as possible BUT that data CANT be right at least not with what I have seen.

And was even shown to bump the head speed up early into the flight didn't Bob.
It looked like a long flight to me.
Bob was that a FP 2170 or 2500 pack you had for him?

[Symon]

Those facts game direct from the owner of Align and AS and JK. They may not be the same as a reps stats but that's because JK's and ASJ's stats are bound to be different as they fly at a different level than us all (especially me )

But they're not speculation.

I don't see taking the word of the people who designed and built this thing as conjecture...to be fair.

[edit]It's also worth remembering that those were also from the first prototype tests [/edit]

[Finless]

Yeas agreed.... They also were testing different motors so true the end numbers now could be very different. Good POINT!

Thanks for the pics.

Now that the 500 is making into the hands of more pilots, 4.5 minute flight times (80% used) for 6S1P 2200 setups seems to be the experience. Not a lot of data on specific configurations (pinion used, headspeed), but the videos are showing a pattern.

So, 7 minute flight times on two 3S Trex packs (2200mAH) may be hard to attain. Perhaps for sport fliers with much lower headspeed?

[Finless]

Yep.... as was said Andy was running between 2600 and 2800 head speed and getting some of those times. Hgher head speed and harder flying will always reduce flight time. Heck as you know we have people getting 8-10 minutes on a 450SE by running 2200-2400 head speed and just basic forward flight stuff.

Time will be dependant on how you fly and head speed.

I don't think getting a 10 min "sport" flight out of your rex 500 will be hard by just lowering the headspeed. 2200 - 2400 rpm should be PLENTY with 425mm blades for cruising and maybe even a little mild 3d (loops / rolls, etc.). Hell, i do that on my 450... I get 9 minutes on my 450 with the reduced th-curve of idle1 (80, 72, 65, 72, 80) with 430XL, 13T pinion ... (3100+rpm in idle2).

Just as an FYI, if you're only looking for arobaitcs (rools/loops/FFF), I figure I'd mention that I got 8 minutes out of my 6SA123 pack using the 13 pinon. Head speed was 2050rpms (on cold packs - didn't measure rpm when I pre-warmed the packs).

I put back 2095 mAh in the pack and it registered 18.4 V when I plugged it to the charger (3.07V per cell).

Can't wait to get that 15 pinion!

[warpspeed]

Aerosports, that MD500E looks HUGE next to the T500! Is it just the camera angle that makes it look that way?

[fireup]

No, it not camera angle, it is huge. You can almost fit the T500 in the MD500E if you extend the boom.

[AeroSports]

yes, the fuse is huge. it flies well. even the plank guys at the field were impressed by it.

Well now that's just totally unfair............. I can't get either one of them. Guess I will just wait for my tax return. They should fill the pipe line by then. Meanwhile I can practice crashing the 450. Nice looking fuse too.
