Status: offline 		Me and my son finally got around to trying our heli.Charged the 650mah 8.4v battery for 2 hours it read 9.4v when done it just got tiny bit warm.Everything seems to go good but it will not get off the ground at full power. I noticed the 4-1 turns solid green when i hit full power it turns solid red then I let off on the throttle it goes back to green?Just doen't seem to have the power to get off.it starts to slide but thats it. Thanks also Ive charged the battery twice now

First thing you will want to do is check your pitch - if it's not enough, or too much, you will not lift off. I set me pitch at 0deg when the stick is at 45% throttle....that usually gives me around 9deg pitch at full throttle.

fixed pitch helis are what the name implies fixed pitch. this means the pitch is always constant and cannot be adjusted.
Frostman55 i dont realy know for sure what it could be but i am shure somebody here in the forum does. good luck

Status: offline 		I have simmilar issues with my hbfp i am using lipos though first off make sure your swash is level. Then i always give a little negative pitch with the flybar. Try different angles with the flybar. It will make a big difference in lift the heli gets . also blade tracking is very important .

Status: offline 		Well we twisted the main blades and it seemed to give it some lift.We had a bad crash into a tree but we got it back together.It's not easy flying these things I want to make a battery pack with 7 1000 mah. Is there a site to show me how to connect them up and where to get the jst connectors thanks guys

Status: offline 		There are some good sites out there for building batteries, which I will probably never try myself. But do yourself a favour and change all your connectors to Deans, they are much more efficient and designed for higher amps. The JST connectors just create bottlnecks. You can find either connector at most hobby shops that sell RC, a lot of car guys switch over their Tamiya connectors to deans as well.

Status: offline 		I wouldnt do that.
A 7cell 1000 mah Ni-MH will weigh about 30% more than the standard 650.
If you are having lift issues now, they will be worse with the heavier pack.
The only thing a 1000mah NiMH pack on the HBFP will do for you is lengthen the flying time.
Its not like a high discharge lipo/brushless motor combination.
It wont give you much more power.
If you want to fly longer, buy a few more 650's

Status: offline 		hi frostman55
the main blades should rotate clockwise looking down on them, if they dont just turn the plug round in the 4 in 1, the green light in the 4 in 1 is right, the red is just to show that it is recieving max signal from transmitter.
some blades although seem ok give no lift, try another pair, they should be ballanced - assemble them onto head [off heli] then place onto two glasses resting on the ball section, they should hold level. if not use sellotape at ends to get the lighter[higher] blade back to horazontl.
then refit to heli, put heavy wieght though skids and spin up to just undr 50% throttle, look from side of heli at ends of blades they should both be in the same plane or within 1mm if not then they need to be lifted slightly [the lower one] with tape under the front edge at screw - this is tracking, very important on fixed pitch, also any vibration at head needs to be sorted check that flybar paddles are flat with control frame- square at head moves with flybar - and exactly same length, the heli will have a tendency to tip left on takeoff, dont be too cautious, once slightly 'light' give quick punch of throttle to get a foot or so up then helli should settle again, this bird wont just sit there hovering you will need to work at it to keep it in one place even indoors, -does not realy like any wind!!!-
but good fun learner bird, fly this you can fly most. swash plate - where servo control links go to- should be 90 degress to mast front and side, to help eliminate the left flight on takeoff you could give 1/2 turn longer on swash link after it is level, thats the link on the side not the front [1/2 turn longer]. also turn rotor so that flybar is out left and right on heli and lift by bar , heli should hold with tail boom horazontal if not move battery to get level.
hope this helps
regards
don

Status: offline 		Thanks Empty I'll just get more 650's. Don Thanks for all the info. Me and my son are having some fun in the basement but the only way we can get it to hover is with the tail spinning around.Were only getting it 2 feet off the ground which isn't helping probably,We got to try and get it out at the park and get it over 3 or 4 feet up. It always goes to the left on take off
It sure seems to take a beating thanks again

Status: offline 		ok so on the 4 in 1 there are two little grubscrews by the green led? one marked gain. turn this left to end, then put other one at center try spinup on shiny floor - unless you have a lzy susan turn table you can fix heli to- [ need lots of silly stuff for this hobby ] then when you spin up it will slide on floor or spin table, try adjusting the slider under rudder stick in tx to counteract spin, - see which way stops- slows it, then turn the other screw a bit on 4 in 1 batt must be unpluged and pluged in again to reset 4 in 1 each time, keep at this till heli stays straight at 50% throttle, took me couple bats to get this, also make sure tail rotor tight on gear -little plastic tube on spindle comes loose, and when turn left comand heli nose should go left, if not move the rudder norm/rev switch on bottom front of tx, these are so that if you change a servo some operate the other way so flick switch and all back right way again,
back to tail, when you have stableised the spinning then move the gain pot screw back towards the right - 1/4 turn increments r ok - untill the tail starts to 'wag' or vibrate then back off a little..
sometimes it takes a while to get helis set up properly but if not setup properly will not fly properly.
regards
don

Status: offline 		regarding flight hight above 2/3ft you areout of ground effect [ backwash ] so up to 6 ft will not make any difference as to the cellar, we are all confind inside but in a room 3-4 yards square after a couple of mins the air will be very turbulant- prob see heli getting worse to control as you go on- [ think jesus getin worse at this not better ] this is the turbulance, school hall etc is ideal for these birds, unless you found your own corner of this world with no wind

Status: offline 		Also I really recomend switching over to lipos . I use deal extreme mystery lipos 7.4 900mah 15c discharge they give the hbfp more power and being a lighter batt less strane on the motor . They even have the esky charger for $8.00 and the batts at $7.00

Status: offline 		Well I see how this can get addicting.I'm finally starting to get some hovers" 30sec" in the basement.I noticed that when the battery starts to get low it's a lot harder to fly.It's no fun having one battery pack just when your getting in to it it goes dead
