Yes, but I wouldn't, unless the tail boom had been stretched enough to avoid tail + main blade interaction. So far, 325's seem about perfect.

Just because you're paranoid doesn't mean they're NOT out to get you...

I will disagree why you ask well my king proved it will work. Now thats just scale flying dont think Id do too many loops or flips or anything crazy like that but Im using 292mm MX400 blades on the king up from 275mm stock. The blades hang over the tailrotor quite a bit but the king head is tall enough to get by. The only real thing you can do is try it. Now if you have SLOPPY HEAD worn dampeners or blade grip slop yeah you'll have problems I'm sure your rex with the longer metal collars that sit up against the o-ring dampener for a tighter 3D head will help and let you fly the longer blades.

The rotor should plane out and not be able to hit the tail.

I enjoy sperimenton.

Greggor wants a G5 that has what I think are 350mm.

Increases stability, flight time , and your wife will like other benefits. If you know what I mean.

outrage probably needs more lift they doubled the voltage on the packs 6S then lowered the headspeed with a smaller pinion I believe that is why they have longer blades. I am skeptic of it until greg gets one and lets us know how it works. I can only imagine the weight of the 6S pack is gonna out weigh any gains in running less amps. I bet it is more stable with the weight but I dont think its gonna be any cooler running.


you wanna spearmint why dont you change your 450 rex to a 6S system. Basically turn your rex into a outrage knockoff.

I are ya

I gotta get me a new tailblock norsman even if I gotta make one any ideas fellas . Does the EXI tailblock come out from the frame So far all I got is the TREXSE and would have to have it machined milled down to fit.

The add says its 12mm ready dont see how though?

Hey dougie notice part 19 or 20 in that drawing its a metal collar that squashes the dampeners making them even stiffer one is longer than the other you get both in the SE version one for 3d one for normal. Oh and since the fiber frame is a split frame any old boom-box will screw in there Just need to find a plastic one to get in there.

The G5 is supposed be more stable than most 450s while at the same time being more responsive and agile. Seems like a contradiction. But I noticed the same thing when I went from the Esky woodies to the cut down Aligns, cut to 8mm longer than stock. Much more stable and more responsive. But more that just being more responsive, the heli is more "true" to the inputs I give it. Not doing more or less than I ask it. Makes it easlier and more satisfying to fly. I can only imagine that going to a 450 is all that and so much more. The 350 sized blades continue that trend, as long as there a strong power system.

Regarding the weight differences. The 6s packs are only 1300 mah so not much heavier than a standard 2200mah pack

Cellpro 2200 3s 25c 181 grams
Outrage 1300 6s 25c 219 grams

Because of the higher voltage, the motor is pulling less current so the lower mah is able to keep up and then some. I'm still waiting for more real world reports of flight times. The 8-10 minutes of hard 3d seem almost too be good to be true. But I can believe the power system performance is better than the status quo. Even though I'm getting 10 minutes with the HBK2, that's really more than I need or want. T500 times are between 4 and 5 minutes, which seems a little short for all that expense.

The Outrage approach is very intriguing to me. But, I've made no final decisions. The 6s configuration causes a bit grief for the charging options. I had my heart set on a Cellpro 10s. But that can only change one 6s at a time. The Hyperion duo will do two packs at the same time, but it doesn't have all the features that are important to me and costs a bit more. I just saw there is Cellpro 6s coming out toward the end of the year, which is likely a better match for the Outage 6s packs. What I really want is a Cellpro 12s should it ever be made.

The MA Fury 450 should be out soon (I hope) so there will be more options to consider.

Bottom line:

Do we all agree 350mm will work on a 450 TREX?

Looks like it could be a problem for 3d. Upright sport flying may be fine.
