JR Heli Vibe - Airskipper - Sylphide - Venture > Venture Question
 
 


Location:

Ive been flying Raptors but wanted a change, so I purchased a Venture 30. This is my first ccpm heli, I use a Futaba radio, and I've figured out the radio setup portion but still have a question. When I give it ele/ail the swash plate moves up just a touch, its not much but does affect the pitch slightly, is this normal or is there a way to trim this out? The assembly instructons of course show JR radio setups for all the different models. Futaba T8UHF is my radio...

Ya I've got the radio set to a 120 ccpm mix. I was just checking it again and with ail. my swash plate tilts side to side without a problem.
Its with ele. is when I getthe swash plate to move up a touch with quick imputs. Its like the rear servos are moveing up a split second before the front servo moves down. This moves the swash plate up a touch just before it tilts.

Did you check all your program mixes to make sure nothing is activated giving these inputs. Remember with CCPM when you give it elevator input, the 2 side mounted servo's should move along with the front servo, all three servo's should move. I'm not that famailiar with the 8U program cause I use a 9C, but do you have a program in your Tx for Swash AFR, if so you can reverse the actions of the servo. Daz...

Yes I have AFR, thats how I fixed the first problem I had with the swash plate moveing reverse. I've got the swash plate to move left right forward aft, all in the correct directions. I guess.......Im use to zero vertical movement of the swashplate on the main shaft with the Raptors with ele or ail inputs. With this ccpm on the venture, Its like the front servo is a bit slower to respond then the rear two. In essence, with forward input the rear servos move a split second before the front, this causes the swashplate to move maybe a 1/16 of a inch up on the main shaft, thus changeing my pitch of the main blades. I guess Im asking is it normal for ccpm systems to exp this movement even with top of the line servos. Im running low level servos for now, but plan to upgrade when I have the funds....All mixers are off.....

I'm just using std Jr 537 servo's in mine, are you using the same servo's for each control on swash?

Now dont laugh....Remember what I said in my last post how Im useing low level servos. I use to and still do fly planks occ., I use a JR652 for my planes so thus I have some JR servos that I figured I would use on this heli to take advantage of the dirrect fit servo horns in the kit. Again this was only temp. till I saved up the money for better servos. The JR servos I'm useing are 504's, they are all the same for all 3 positions. I guess I'll find out if it is the servos when I buy new....

 , I cant stop laughing, just joking.The servo's may be the problem but those are probably decent servo's probably not BB, which I would recommend a better servo. The 537's work great for this Venture, you may wanna take a look at those, but JR charges quite a bit for there std servos, I got mine with a flightpack, so they were alot cheaper. let me know how it works out.
