Knight 50 3D or T-rex 600 nitro
I know everyone will pounce all over the align machine to be the one to get.. But how would the knight 3d compare considering parts price, flying (3d), and etc...

I have a Knight 3D and a T-Rex 600. Can't say I like either one of them any better than the other as far as how they fly. The Knight 3D looks and "feels" a bit more solid than the 600 (which is as near as I could compare to what the 600N will be like). However, I think that may be a function of the difference in weight, power, etc. between a 50 size nitro and a 50 size electric.

The price of parts seems to be somewhat comparable. Heliproz has the Knight 50/3D parts listed on their web site, or you could call RC Heliworks to get some comparison prices against T-Rex 600 parts (assuming the parts specific to the 600N will be similarly priced). Either way, the Knight 3D parts prices are not the most expensive I've ever seen even if some of them are a bit more than Align's dirt cheap parts prices.

The big difference for me when I made my purchase decision was that the Knight 3D is already available and the 600N isn't. I didn't want to get caught up in the same kind of limbo that all the pre-order Aurora guys are in. Since Align has a bit more market momentum, I'm sure they'll get it released pretty much when they say, but a few weeks delay or a few "critical recall" issues could put it too close to the end of the flying season. IMO, that makes it a possible choice for spring 2008 but not for this year.

I jumped and bought a 600 electric last fall right after they came out, and had issues right off with the puffy pillow align 4400 batteries even if I held back to gentle forward flight. Later, (after I switched to EVO 20 packs) the stock 10 tooth brass pinion gear in the 600 sheared off part way through a loop and forced an auto. I replaced it with a steel Mikado pinion, btw. A friend of mine has had a few issues with his 600 too (like tail grip bearings full of lock-tite from the factory). I say all this because I expect there will be similar design and manufacturing issues with the 600N for at least the first 6 or so months . Even if the 600N were available when I bought the Knight 3D, I think I would have made the same choice.

I guess Align will be shipping the first batch of 600N's to the early-adopter guinea pigs soon but I don't think I'd want to be a beta tester for them again, especially at my own expense.

my choice
having seen them fly back to back nothing performs better than the TREX6000,even with all the B/S about gears motors batteries and esc the rex 600 still dominates.

Assuming airboss is talking about the T-Rex 600 electric... yes, it flies a lot "hotter" than the Knight 3D because of the electric "power on tap" thing and the pound or so less flying weight. I'd bet the comparison of nitro vs. nitro once the 600N hits the stores will be much closer. If I were comparing the Knight 3D with the 600 electric, I'd also have to mention the 2X+ flight time on the Knight 3D, but I wasn't really trying to compare a nitro with an electric.

Just to be sure, airboss, were you talking about a 600 (electric) or a 600N (nitro)? The original question was about the 600N (which isn't out yet), compared with the Knight 3D. I was trying to guesstimate what the 600N (nitro) will be like based on on my experience with the 600 (electric).

I have both. I haven't flown the 600N yet but the Knight flies very well. Is this your first heli? If so I would recommend something other than the 3D. Sorry Compass but your manual sucks big time. Someone who has never built a heli will not have an easy time. Sure you can get help on the internet but that only goes so far. If I could only keep one it would be the 600N. It will have a much larger user base in a few months and be easier to get parts and support.

I'll second GScott's comments on the manual. It's absolutely useless. You'll do better throwing it away before you try to decipher it. I also agree about the parts and support issue since Align already has their stuff on shelves everywhere. In a few months, the 600N will definitely be the better choice. I don't think either one of these would be a great choice for a first heli since they're designed for performance. If all you're doing is learning to hover, choose something that won't nail you for around $115 just to replace a broken frame _when_ you crash. http://www.heliproz.com/prodinfo.asp?number=360029

(BTW, the frame for the Knight 3D is G10 fiberglass so it's a bit cheaper http://www.heliproz.com/prodinfo.asp?number=020832 $27x2 + http://www.heliproz.com/prodinfo.asp?number=020812 $8 = $62.

My current heli's are raptor 30, raptor titan, raptor 90se and synergy n9.. This would be my 5th heli..


rthomas67,
Thanks for your inputs... I am sure the electrics fly somewhat different than nitro but I have nothing to compare it to other than a 5 minute flight I once gave a 450se... My favorite heli (by far) is my synergy.. Very responsive (which is what I like) and very precise... However, I am having dificulties working out some kinks after a crash and now I have crashed a second time while trying.. Both crashes I have on that heli were mechanical/electonics (first rudder came unplugged.. 2nd not sure if link popped off or what just had no control)... My friend has a knight 503d and loves it.. He flies mode 1 so i can not test it out.. He also has a different flying style than me but he is reallly impressed with the heli.... He likes the cost of the replacement parts..

He and I have discussed which would be better (600n or KNight 3d) and can not decide... Thats why I ended up with this post...
