Default Hover Problems w/ Superskids

OK- its been a week now with no hovering above an inch off of the ground. I replaced the stock gear with Superskids, charged battery, install, fire up, and nothing- it just skoots around. I then investigate further and remove boom supports and horizontal fin thinking weight is an issue. Charge battery, install, fire up and nothing- just skoots around. I investigate further- find that main gear is rubbing on the rear skid support. Turn that around, reinstall. Charge battery, install, fire up, and nothing- just skooting around. Before I installed the Superskids, I could hover at 3-4' off of the ground, no problem, the main gear was just really squishy. Last night it took almost all right tail rotor stick to keep the heli pointed straight. I haven't changed anything. Is there something I am missing? I have a slo-max 300 and pinion on order. I'm kind of frustrated right now. Any help would be appreciated.

Take a look at the thread on this site for HBFP initial gyro/proportional settings-maybe that will help.

Brian, your problem has nothing to do with the SuperSkids unless you already have a bunch of extras on board the heli. I have no boom supports or horizontal stabiliser on my HBFP, where did yours come from and what else have you modified?

I had to add some postive pitch the flybar paddles to get off the ground using the stock Ni-mi batteries that came with my HBFP. Otherwise it would just skim around on the ground and never really lift off.

My HBFP doesn't require any positive pitch in the paddles to fly.
In fact, my HPFP ripped up the sky with the stock battery.

If your HB can't get off the ground, I'd question if something is seriously wrong with the motor or speed control.

Is there any way to get a quick movie of it? I'd be able to tell if it's getting head speed rpm by the sound.
Or, check out mine here flying. Does the head speed sound the same?

Another thing you might check is whether you have any interference from wiring, etc from when you mounted the new superskids. I put mine on and most everything there is in pretty close to the main drive gear. Usually things are simpler than they first appear. My Honey Bee MKIII FP is hovering great with the upgraded gear. Good luck!

Default Give it a try

Guys-
My HBFP is bone stock w/ the exception of the superskids. It is also brand new and flew great until I put the skids on. With the stock lipo or a 1300mah lipo it won't get off of the ground. It sounds just like it did before I upgraded. I'lle investigate tonight and if I can't make anything happen, I'lle post some vids or pics.

Thanks,

Brian

Check to make sure that you don't have any negative pitch in the flybar paddles.

Default About the paddles

I seem to have to adjust the pitch nearly all the time. I am using a cf flybar the same length as the original. I attempted to put locktite on the nut on the screw, but it doesn't seem to help. Any additional advice?

THanks,
Brian

OK- Flew last night. Adjusted the paddles to a touch of positive and it would get off of the ground and hover around.

I have another question. It seems that with the stock motor it will not hover very long. At full throttle and full up trim it would barely get off of the ground after probably 5 minutes. I bet I only got 7-9 minutes tops of flying off of the stock Lipo. Is this normal?

it's obvious the super skids are lead weights holding you down.
Extra weight takes full power.
Full power kills battery faster.

Just make some skids yourself outa .080 carbon rod.

I can get about 10 minutes out of a battery. If you are hopping around, using full power in bursts it may use up battery faster. Superskids aren't really that heavy IMHO. Glad to hear you got 'er hovering.

Default Update from the weekend's activities

Update-
Friday night I removed the superskids and re-installed the original landing gear. Saturday it hovered great. Eye level etc. I didn't get a chance to run through a whole battery pack as the wind was kind of high. That was with the stock lipo. Later that evening I tried the 1300 mah lipo pack and was barely able to get it off of the ground. My question is- is my exisitng motor just burned up? I probably have 25-30 packs through it. It just seems tired.

STOCK LIPO? Do you mean stock Esky from another heli? In any case, my heli wouldn't do squat with my stock NiMH batteries, so, I assumed they were the cause. A friend is loaning me a Lipo until mine arrive and it is back to what it used to be. I suppose it is the normal progression for the batteries to go South with either/ both motors soon to follow. If you've already bypassed the NiMH battery part, it could be the motor.

my original Nimh batterys ROCKED.
They had way more initial power than the lipos I just bought.

Charge the nimhs till they get warm and go for it.

I was always told to do 2 hours of charge on the NiMH. Later, I was told that was too much. I eventually got to the point where I just couldn't do much of anything except RADD's. It just wouldn't pick its butt up off the floor.

My NiMH's wer great too, but charging for more then 2hrs isn't recommended, theres an actual way to calcuate it, and when done the max charge time is 2hrs 10 mins, I actually lost a NiMH due to overcharging

every nimh is different. Using the cheap charger that comes with the HBFP, I have always charged the batterys based on heat.
When the pack starts getting warm, monitor it closely cause it gets hot quickly after that.
I used to let mine charge for a couple minutes after warm and before hot.
One of my nimh batterys takes 3 hours to get to this point. If you don't charge it till warm, it lasts about 5 minutes and is way under powered.
The other nimh batterys take around 2 hours.

I haven't had any problems out of these batterys yet. (knock on wood)

Well then, I guess you need a thermocouple or two to charge the batteries!

Why? Can't you sense temperature?

~130-140 degrees for full charge.
