This is going to be my second heli. I had a 450SE for a few months as my first bird, but had to sell it because my car needed some attention. I'm looking to see what your opinion would be on which heli you think would be a better choice as a second heli. I've done a fair bit of research, and see that the TT heli isn't quite as popular, but I'm going to guess that's because it's newer.
As far as getting parts goes, I'm going to have to order either way, so that doesn't come into consideration. I know that TT has inexpensive parts when compared to other companies, but that's also a high point of Align, so that's one point where I get stuck.
What I'm really looking for though, is from those of you who actually own and have flown both. Which would be the easier bird to set-up and fly? I've got a pretty good idea of how to set everything up, after watching the finless vids, reading manuals and tweaking on my own. Any opinions and maybe some recommended set-ups?

Not sure if this is the right place, but I figured I'd find more guys that owned both in this forum than the Align Forum.

I've got an E550 as well as a Trex 600 so I can at least comment upon setup as the E620 is basically the same. The controls are pretty easy to setup on both the TT and the Trex except the TT uses either 90 degree or 140 degree CCPM, presuming the 140 degree swash plates are available now. I went with the 90 degree as my 9303 doesn't do 140 degree! The only down side I can see of this setup is that you have two servos sharing aileron control but only one on elevator and so it needs decent servos. I've crash tested my E550 and it's pretty strong, spares pricing seems a little odd at the moment, E Raptor specific parts seem to be priced quite cheaply but the stock Raptor parts are a fair bit more expensive than comparable Trex 600 items.

That's strange about your 9303 not doing 140 degree swashes because mine does. Wonder if your's is either an old one or being one that's from across the pond. Mine is about a year and a half old.

I'm used to having the 2 servos on Ail and 1 on Ele. That's how the T-rex is too. I'm not sure if it makes much of a difference due to the size of the birds though. What's the big advantage of setting it up for 140deg CCPM over the 90deg?
Seems like you make it sound these birds are pretty equal when it comes to performance, so I'll probably just wind up going with the E620. Personally I like the look of it better anyway, and it's not really much more money to set-up.

Also, what would be a good motor/battery/pinion set-up for a combo of flight duration and performance. I don't need absurd performance because I won't be able to put it to use anyway.

Mine is actually a PCM 9X and is the first model, it was replaced by the PCM 9X II which does include 140 degree swash. I can send my transmitter away to be updated at a ocst of around £35/$65 but I fly all year round and can't do without it!

MikeWz,
Yes, the Trex 600 has 2 servos on aileron and one on elevator but because its 120 degree if you apply forward cyclic the elevator servo arm rises but also the two other servo arms fall, otherwise you would get interaction. With 90 degree forward cyclic only moves the elevator servo, the other two remain stationary, not much difference but enough so that I could notice the elevator being 'sticky' using JR DS811 servos.

The 620 is more expensive to set up because of the cost of battery packs, presuming you run your 600 on a 6S setup, the 620 really needs 10S to shine. Its also more expensive as a kit to buy than the Trex 600. If their available yet the TT motor and speed controller intended for the 620 should do a pretty fair job, their setup for the E550 is very near to the setup I've installed and this works very well, same for the E325 Mini Titan.

I have played with some numbers regarding parts cost, I'd have to say the two are very close.

ACE offers crash kits for their helis, Align does not. This brings the price of parts down on the 620.

Ticidy, which do you prefer ? :noteworthy

The 620 is still very new to me. I have only tried one power system so far, so it is way to early to tell.

I will keep you guys posted as the systems get tested.

My 620 was as blinged as you can possibly bling, with good bling to, useable stuff. Anyhow bottom line is even then to me it was abit of a beached sealion. I sold it in less than 20 flights.

Getting the HS up wakes the head up. Running 2k is not going to do it on the TT head.

The other problem, is weight, its heavy, like the Align. This is why I'm running it stock, or as close to stock as I can. Al. weighs more than plastic, the only place I am willing to add that is in the grips.

So what next, well, make it lighter, I tested something yesterday, 7lbs 10oz. You can feel the 6-7 oz that are gone. Id like to remove another 6oz but I know thats not going to happen.

What exactly is it that makes it so heavy? Is it the battery you have to run to get sufficient power? It's surprising, considering the CF frame and plastic head and tail components

So far here is what I found:


1. Canopy - The Align FRP canopy is 3oz. lighter than the Raptor "bleachbottle" with stickers.

2. Landing Gear - much stiffer and stronger gear on the E-620, the Align gear is very thin and flexible 1.5oz. lighter.

3. Boom Supports - Align are under .5 oz(ea), the Raptor are over 1oz. (ea)

4. Main gear and main shaft very close.

5. Head - Very close TT is lighter by 1 oz. (both with metal grips)

If you really want to put it on a diet, get the xero-g conversion. I'm building one right now. I was told its ALOT lighter than the 620 and blows the doors off of it with a neu1515/2y on 9t with an 86t main gear...only problem is the conversion kit is $400 :shock:

Am I right in thinging that the TRex 600 uses 6 cell lipos and the TT 620 uses 10 cell?
I had a look at a TRex 600 in my LHS today and I was very impressed! Soon as I can fly comfortably with my Mini Titan thats gonna be the one for me. :D
