Question!!!!!
Do you guys seal the hinge gaps with hinge tape or other material?
Have you flown with and without doing it? does it really make any difference? I read that if you do it, it will have better lift when fling slowly.

Thank you!!

I use hing tape. I've tried clear film...but it's a pain in the backside to get on right with an iron.

As for "does it make a difference"? I really have no idea. I'm fairly new to 3D, and I've flown both ways...and I can't tell the difference...but then, I'm half out of control most of the time anyway! I do it because everyone says to (I'm a lemming)...I pay my taxes too...because everyone tells me too.

3M makes Blenderm and it works great and is easy to apply. It is nearly invisible after it is first applied, but the edges pick up dirt and eventually the clear tape has a black dirt outline. On the other hand, using Ultracote or Monokote takes some time and patients but once you get it right, it looks great and lasts a long time. Neither will affect the control surface throw if applied correctly.

Which is pretty much exactly what you just said.
I unplug the resistor after the major connection is made.

I seal mine with matching ultracote or clear monokote. Does it make a difference, well that depends on how good or bad your hinge gap is. A small gap will be fine if not sealed, meaning less than 3/32".....JMHO though.

I seal the aileron gaps with blenderm tape. It's very easy to do and it's invisible. It makes a difference with moves where your wing lift can "leak" through the aileron gap, i.e. elevators and harriers. I get a little less wing rocking when the these gaps are sealed. Makes no difference I can see in any other maneuver though.

I have a question of my own: I think I put too much CA in my elevator hinges and they are a little stiff. What do you guys recommend to soften them up a little bit? I've used CA debonder on them but it doesn't do much.

Work the elevator with your hands numerous times, flexing it to its limits. I would NOT use debonder as you may loosen the original bond.

I use Blenderm to seal my hinges but run it through water first to make it easier to apply.

TMSN
A lot of times use alone will free them up after awhile.

i do it for aesthetic reasons....with oracover in the matched color.
blendern tape works the same, but its pretty ugly.

as for flying...at full deflection there is basicly no gap anyway (or at the time the air had found its way through there, you normaly have changed direction by then.)
the brain tells you to seal...experience says it flies at least as good without

And yeah, I always use 100A ESC's for 8S where there is a potential for 70-80 Amps as long as I'm not sacrificing weight. Adding the extra headroom always seems to eliminate some heat and flying in the Florida summers means running a cool electric setup or suffer the consequences.
I thought about 5.5mm bullets this time too. I also saw the Jeti anti spark bullet- pretty slick, but I wanted to try a DYI, so went with the resistor idea. I used deans simply because all my batts ans esc's are deans. I could have gone with the Jeti anti spark and 5.5 mm bullets, but simply chose another direction.

I know deans are rated at 60A, but thought with this setup, I would be pretty close to that. I will have to go with bullets if I move the ESC to a larger airframe....

I disconnect the resistor after I have the serial connector plugged into the ESC- to remove any add'l resistance. But if I read correctly, there does not appear to be a reason to do so- is that correct?

I know Ive told this story before....blenderm has saved my plane. I seal all my hinges with the stuff. One day I noticed the plane felt a little weird...it still flew, but something wasnt right. I landed and found that all of my elevator hinges were broke. Only thing holding it was the blenderm. I have no idea how long it had been that way.

Did you have the Blenderm on both sides or just one?

LL, it has been covered many times that the sealing of gaps has nothing to do with the slow 3D flying full deflection surface but a lot to do with air passing through the gap effecting the transitions and pressures on both sides of the control surfaces that are critical.

In a lot of cases its very hard to notice anything, try the MXS with 4s sealed and unsealed, I am sure you will feel the difference in the accuracy of the control surface.
