wouldn't that make the gyro bass ackward?

if you turned it around, the gyro would have to be past the main shaft. (toward the rear)

I know this, because I tried it last night and during my first spin up, the heli went skittering across the floor doing piros.

My job was 1000 times more complex than any production job in the plant,

a few dollars more than them, because the union agreed to a maximum
hourly wage cap. Production kept getting raises, while my pay stayed the same.

If you are an intelligent talented worker, the Union really does nothing but
take your money, while it fights to save the people that SHOULD be fired,
due to lack of talent, ambition, attendance or any other issue that would
normally get you canned.

Look what you started. Now I'm pissed off.
There you go.. A pissed-of disgruntled Union worker, I like it!. Time for some major re-adjustments in the USA. Suffices to say that I am dead against the stranglehold Unions and thus the Democratic party has.I just hope you did not vote for the cool guy!! He is eating us for breakfast.

as long as the gyro is behind the main shaft, it should be good.

if you look at postings under the "no more smashed pcbs" thread,,,I posted pics. of the mods I did.
Out of logical sense, I put the pcb tucked away and had no ill gyro effects or r.f. interference at all,
many,many (a lot) of flights later, I still have the original pcb the old crow came with.
I you look at the batt mount system I made, I just mount the batt higher for more agressive flying, and lower it for more stability ( c.g. shifting)
aside from the tail motor mods I still need to do,I modded it up with scraps of stuff and hand fab. things and have a blast flyin it....-
note:all the wires were resoldered and are facing the front of the bird so the wires are away from the main gear...

Looks good, I might adopt your design. I like the idea of being able to move cg as well as being able to mount the std nose cone. Interesting that the reversed gyro works good.

Did you reverse the rudder on the tx?

Went and did it

Well I went and moved the pcb under the motor. The gyro is exactly 1/2" in front of the main shaft. It's a little further back and lower than the position simz has his mounted. The front edge (which was previously the back edge) of the pcb is in line with the front screw of the outer side plate.

I was a little worried that it might be tail heavy, but it's not. It had a heavy drift to the left that it didn't have before the mod, but I trimmed it out at the swashplate and it hovers fine.

Tomorrow I'll try it outside and take some pictures to post. I think probably the concerns over the gyro not working right due to repositioning are unfounded. At least I hope they are!

lalalala

sorry steve I have not posted in awile been to busy flyin and tending to the frostbite on my fingers (they need to come up with heated sticks on the Tx. like having heated seats or steering wheels in cars)
like you said, I have more aggro. on the ailerons with the batt. mounted higher-
with it mounted lower, it has more weight forward and better forward flight and more stable.....it seems to be a trade off as to what kind of flyin your up for..
all mods I have made have no ill effects (i.e. tail wag ect. ect.)
and I still have the orig. main motor and tail motor and pcb. the bird came with still installed((((knock on wood---till my knuckles bleed))))
-I spent more on gas driving to parks to fly at than I spent on the mods I made..
will gladly share the other mods I have done as that this is what this thread is for.
--pooling our collective thoughts together for a better outcome..

Got a good flight in. I really need to reduce the weights on the gyro. I could dip the nose and get a good run, but then it was swinging all over the place like it was on a string. I didn't crash, but I came close to some trees several times.
