600 EFL Pro
I did like to run a lower headspeed. I chose to use SAB 100mm for the tail blades. I think Align should make 100mm blades as they could be used on the 600 and 700 as alternative in HS and gearing. My DFC crashes were better than I expected. I think in any crash if the battery is unplugged, the collateral damage is much less. In the end brand choices are subject to local support, both in help and parts.

Im running the stock gearing for the Trex 600EFL PRO and don't have any tail blow out issues what so ever running 2200RPM up to 2500RPM as I adjust gain for each headspeed..For guys having issues and can't get it set up right,all you need to do is change the auto gear and front TT gear set to the past set <--- You can run 1700RPM with that gear set if you wanted so no reason in trying to make it sound like people are stuck running high headspeed.You can run 2200RPM all day long with the if you know how.

As for the DFC head,learn to hit throttle hold...I made the mistake of not putting hot glue on my servo plugs and had one come out..Headspeed was 2500RPM and it slammed into solid ice which is the worse inpact ever for any heli.Hit throttle hold right away when it freaked out and the whole head was perfect,all it did was pop the links off the swash balls..

Watch at YouTube

Its been repaired and I didn't have to change a single part on the head thanks to knowing how to hit throttle hold like I should..The same head in the above video is flying 100% perfect as you can see..All I did was change the frame sides and other normal crash parts...All head parts,shafts,gears were never replaced...

Watch at YouTube

Like I said.If you can't setup the heli good,you'll get poor performance..If you don't know how to hit throttle hold right away,you'll break parts that shouldn't break....

Sorry, I thought when you referred to your crash from 5 feet off the ground as a "total re-kit", that would include the head, tail, shafts, gears, etc. Lucky for you, it wasn't that bad.

I own and have setup many helis so my setup is just fine. I just don't like how much energy the DFC head transfers to the servos. Anyone who has built these heads knows how hard it is to get the links off the swash. This ususally leads to them bending the arms or just transferring all of the energy to the servos. I have been around for plenty of crashes of both style heads and the DFCs have had the shorter end of the stick in that department. As far as the tail, most people know this can be fixed with the other gear ratio. I was referring to how the kit comes from the factory.

I also know how to hit throttle hold, I just prefer the v2 head for the reasons I mentioned. The dfc head does fly awesome, I just think it can be improved so for now, I stick with the v2 head and they perform quite well. It is all personal preference. Luckilly in this hobby we all have many options to choose from.

Say what you want but anyone can see that was a rekit as the frames,whole tail section was trashed along with every bearing other than the head and auto bearing .Being as you don't know this,a rekit is when all the crashed parts add up the same as a new airframe which it did...
Anyone thats built MANY Trex 600E's know a simply swap of the auto gear/front TT gears changes the gear ratio..If you know this,then why are we talking about it?If ya don't like the tail gear ratio then change it,no more complaining..
Also,
You can clear as day see the whole head and all that happend was the links popped off just like I said..Thats a hell of alot better than having to buy 2-3 link rod kits for the older head and everyone knows they fly off just about every time during crashes..Been flying Align pretty much 5 years stright along with 40+ people in our club,just about everyone went DFC because it cost less and damage is less when crashed..

Heres a easy way to do it for people that built MANY Align helis..Next time you crash,change the gear ratio <-- Problem fixed and go fly 1600RPM if ya want..
Guess you can say alot is personal choice other than the gear ratio...
For people that don't know and haven't built many 600's,change the auto gear and front TT gear set...

My original post about my opinions on the 600 DFC was directed at the person who opened this thread. He has not built "many" 600Es, he is completely new to the heli which is why he opened this thread to ask about it. This is why I was posting my thoughts on a heli that is completely new to him that I have owned and flown for over a year.

I was just voicing my concerns with the heli he is interested in. Obviously you are very happy with yours which is great, many people like it including me. I just wanted him to be aware of some of the issues I have run into.

You pulled one of my threads in your post and was talking to me so didn't know you were talking to the OP LOL...
Its all good man and I was just letting him know that others don't have them problems and the gear ratio/headspeed isn't at all a problem ..
People have a choice which is to run the 600EFL PRO gear ratio or take $20.00 bucks and change it.Then you can keep the 600EFL PRO gear ratio in the parts box incase you wanna change it down the road or just sale it.
