Quick question is the head with plastic grips the limiting point of the headspeed...If you were to use a full metal head could you push the headspeed up to 2000-2100 with 690s.

Thanks guys

Mikado says 1800 most run up to 1900.

Your answer is "yes". I've seen RJX and Outrage heads mostly but as soon as I say that there will be 10 guys yelling another name so brace yourself for the onslaught.

with a metal head you could probably get those speeds safetly, but i'll tell you, 1800 on a 600se feels like 2100 on a trex 700e from what i understand due to the large weight difference.

perhaps someone with firsthand experience can comment (i have a 600se but have never flown any other e-700 ships)

I run 1870 on a stock head with TrueBlood dampners and wouldn't want 10rpm more than I have already. I've almost considered not changing the head as I'm very happy with how it flies as it is. Why dump a few Bennies just to shorten my flights? I don't think it's a "need" thing but coming from a Rex700 has folks in the headspeed world and it takes a bit to acclimate back to the real world where it's not needed in a Logo.

tail

I thought the limiting of headspeed was due to the small tail bladegrip bolts with the 105 tail blades.

Good question JStage. I have the QuickUK tail on my bird as I run 105 CYB tails so never had that limit. Definitely worth knowing though for sure.

Limitations on the Logo 600SE

Jeff is correct. The "head speed limit" Mikado placed on the SE (which is 1800, buy as stated, many push it to 1900 without issues), is two fold.

This is all old news to most the regulars on this forum, but we always have new visitors, so I'll review.

One, is that the head and dampening system was originally designed for 600mm discs. The reality is the head dampening just won't hack 2000+ head speeds as is typical with other 700 class electric helis.

The equalizer in the equation is that the SE weights about 9 1/2 pounds ready to fly, as compared to other 700E's that weigh 2 pounds more. So the performance is there, even at the lower head speeds.

Two, is the 2.5mm bolts that hold the tail blade grips, (as with the head), were designed for a 600 class heli (95mm blades), and as the SE needs 105mm tail blades in order to have enough tail authority with the lower head speeds and larger disc, higher head speeds with the larger tail blades can cause the bolts to fail (a contributing factor in all this is that most guys over-torque the small bolts during assembly and help the failure process along).

So Mikado rightly placed the limit, and human nature being what it is, the first thing many did was to exceed it in the interest of more performance.

Some choose to change the tail parts and replace the head, which is fine. But in its stock configuration and flown within its stated limits, the SE is fine, and is unique and different in the "700 class" heli world.

Most definitely, it feels so smooth and graceful in the air! Not like any heli I've ever flown. Its almost like it "wants" to fly, rather than your forcing it too!

Gentlemen heed the tail blade grip screw failure warning at higher headspeeds.
A friends SE recently tossed a tail blade (complete with the grip) and of course the helicopter went ape. Fortunately he kept his cool (this guy is ice cool) performed a perfect auto after flipping the switch.
Upon inspection we could see that the bolt had sheered and half was still inside the hub (we never did find the renegade blade)
He had been running headspeeds in access of 2000 and possibly that may have led to fatigue to the bolt.
I recommend replacing the hub with either the QUICK UK or the ALIGN 600/700 hub and grips.

tail bolt losing it's head is usually from tightening too much. I've seen this happen in other makes as well. I use a small drop of green locktite and then just fasten it enough to take up any play, or in some instances where play still exist just finger tight. When you stretch a bolt it takes very litttle to lose the head, keep this in mind whichever tail you run

Common sense may not be common after all
