View Full Version : Blade CP Pro setup in JR TX?

Hey guys, i've swapped the rx in my BCPP to a JR system. I had some issues with glitching with the other system i wanted to try and fix with the new one. plus now both my trex and my BCPP use the same TX.

Only problem is, i can't seem to get it set up right. The directions and stuff are all correct, but i have intermittent issues getting the tail to hold. Sometimes it will hold just fine, other times it wants to just constantly piro and no amount of stick input will counter it. also the controls don't seem as locked in, like more input is needed for the same level of reponse in the bird. While i know these are both settings in my TX (JR 8103H) i'm really not very good with getting these things set up well.

also, is there a easy way to set up the endpoints on the throttle channel with using the brushless upgrade? THanks a bunch guys.

I don't run JR but have helped others setup JR. So anyone with this combination chime in please. I don't have a BPP either, so I'll go generic here, in hopes it helps.

On the tail I don't know seems perhaps coincedental like maybe the motor being flaky showing up after the change?

on the soft controls I like to set up the collective and cyclic for max non binding deflection in swash AFR and then use end points to tune down if needed (usually not)

End points on the throttle are set the same as any other chan. I just keep increasing the low stick EP until the ESC won't arm. Then back off a few % until it arms reliably. For the high end the Castle PHX controls I mostly use have a LED for WOT. I simply set TC <norm> for 0%, 50%, 95%, 95%,95% then hover and adjust until the LED just goes out. Then check/adjust until lighted at 100%. Don't know if the BPP has a WOT indicator or not. If not I just skip the high end adjustment and tweak the TC for constant HS as much as noticable.

Steve,

Thanks for the input (and the move)

I don't have the swash mixes set to max, right now they are set to 60%.

The servos are all mechincally adjusts to as close to horizonal as can be at zero pitch, then subtrims used to get them just right. linkages were then adjusted to get the pitch to zero at 50% pitch input (zero pitch)

Throttle Curve is set 0%, 40%, 65%, 85%, 100%
Pitch Curve is set 25%, 45%, 65%, 85%, 100%

I know that these need adjusted, and i'm open to suggestions what would be a better setup.

As for the gyro, i think it may be an issue with it not correctly intailizing the gyro in the correct mode. I'll play with it a bit to see.

As far as max swash AFR goes it is as much as you can go without binding in any combination of cyclic and collective. Be that 20% or 100% it's still the max.

The TC and PC looks like it'll work fine. I like a little more HS in the middle. My stuff is usually setup closer to TC <norm> 0,XX,85, 95,100. Where XX equals a high number that is still easy to spool up smoothly. It's all a matter of preference. Though it looks like you'll be breaking into a hover at mid stick and around 50% throttle (assuming mechanicaly centered with 0 pitch @ 50%.

It does break into a hover right at or maybe a bit before mid stick. I'll try getting the swash mix up to max and then ajust the endpoints to allow full stick control. I was thinking or setting up the dual rate or maybe trying a bit of expo in the cyclic controls to see if that helps make it feel more locked in and responsive.

As for the tail, i'm really wondering if it's not the gyro (the e-flite HH one)not intialilizing correctly. Sometimes i have issues with it not intializing correctly and it requires unplugging the batt and plugging it back in. I can always tell when this happens because the tail will not work at low throttle and you give rudder input.

Normally one makes sure the HS is up and you are getting a couple degrees negative pitch up to 50% stick. At 50% stick is where you want the positive pitch to start coming on. You really want to fly in the upper 1/2 of the stick. Well I guess if you KNOW you are only gonna fly scale You could use the whole stick but I don't think anyone does because the stick movement would be grossly out of proportion to the other sticks. and some other reasons.

I just don't use 4n1s so no real idea on the tail.
