View Full Version : Bad Gyro? Blade Cp Pro

I have been flying a Blade CP Pro for about a month. I put an Eflight g90 HL Gyro on and it was working great... for a while.
I have been having a lot of problems while in the air, as soon as I give it throttle the heli spins (piro's) badly and Does not seem to counter the rotation. I just tried to fly in idle up mode (which I do not do often) and the heli stays straight with the head-speed constant but I have no control when giving it right rudder.
I had a DD Tail on it and a few other mods which I have been changing back to stock one at a time to try to figure out the problem, and now I am back to a fully stock machine except for the gyro (g90). If I throttle it up while on the bench the gyro counters any of my (manual) rotation and feels right, but in the air as soon as I go for any height I lose it pretty bad.
Great forum by the way, I have learned a lot of info from all of you while lurking around.

i think your tail motor is dead. unplug your main motor and see if the tail works. then unplug the g90 and give gyro control back to the 3n1. if it still has the same problem id bet money its your tail motor.

I just bought a new motor when I went back to the stock setup. It was doing the same thing with a new DD setup also... I will get a new motor just in case since the hobby shop is right next door to work!!! We will see.
Thanks for the quick reply.

It was the tail motor! I must had gotten a bad one the last time, because everything is working again. Thanks guys.

Remember not to get the gain to high on your new gyro. It wil burn up your tail motor quicker. Also on your 3n1 their is a mixing adjustment. Adjust it to keep the tail from kicking around under aceleration of the head. The DD tail is very nice once setup right.

I am back to the dual tail setup. The DD Tail motor must have gone out, after just a very short time of flying. This had caused a crash, so I rebuilt with the same results, spinning and "CRASH!" I put it back to full stock and must had gotten a bad motor out of the box. I was worried I blew the gyro or the 3-n-1. Luckily that was not the case. I guess you can never count anything out with these.

I will give it some thought. I am still in the process of learning forward flight and after the last few weeks of crashing into everything in sight, it will take some time to get back the confidence I had.
Just this weekend alone I went from the stock TX to the DX6... back to stock to eliminate user error for the tail problem... then back to the DX6 after fixing the problem. And I had the wires run so nicely too! :lol:

No. I do bend the main shaft every so often. The crashes have been pretty bad though.
1. I live in a town house and the thing caught a breeze as I brought it up over the roof line, it spun in the wind and I lost it over the house across the street. It ended up on the neighbors patio. $$$ Main shaft, bent spindle, broke one of the blade grip control linkages & boom.
2. (Same day) testing it out in the back yard... hovered fine on the deck, i gave it throttle and it spun crazy into my own house. This was still with the DD Tail on. $$$ Broke landing skids, boom & wires got cut by plastiblades and the lipo went through the canopy!
3. Next day at the park (Now with Stock tail motor and set-up... but with a bad motor off the shelf) Holds fine while hovering close to the ground, but wind blows the thing around until I was forced to land without a crash... one f the blades catches the grass and flings the tail around so hard $$$ boom strike and severed tail again.
Pretty hard crashes and no real damage to the head components except for a missing link!
Now though everything is good. I am in the process of tweaking the settings on the TX and flew it today before the rain hit. Pretty windy with gusts and the thing held fine with a little work. Does anyone else have a problem with the wind throwing the CPP way up in the air? I have to drop the trottle quite a bit to bring it down.

thats how its supposed to happen. the wind blows and its like adding more throttle. try this, try having a huge gust of wind blow your cpp about 30 ft. you lwoer the stick to where it stops climbing then bam the wind just flat out dies. and the cpp drosp 30ft in under 3 seconds. it stoped about a foot off the ground then went back up to head height. i had to land and turn it off for awhile.

Well at least I am not the only one. I have broken a few tail booms because I come down too hard in the grass and it digs in and "WHAM"!!

I saw a guy at an airshow try slowflite infront of the crowd on a gusty day, the wind quit and so did the airplane, from about 40 feet. It did not hurt him but the airplane was down for maint. for a while.
