Building pluma 3d biplane help

[jpandrewsd]

Hello,

This is currently my first kit build and I decided to go with the Pluma 3d biplane. I've managed to put the plane together rather well and managed to even bind the surfaces to where they have nice fluid movement throughout. Unfortunately, I'm having an issue when engaging the motor. Prior to engaging the motor, all the surfaces move docile, have large degrees of movement and are very quick. Upon the motor being engaged(not spinning) just activated, all of my control surfaces lose large degrees of freedom and are slightly slower than before, my elevator doesn't even have the capability to let my plane point downwards, only up now.

The specs I'm running are the manufacture recommended set up for indoor flight:
3 Futaba S3114 Micro HT Servo
Eflite safe Rx, unused(I had an extra from my older S-15 apprentice)
Motor - Rimfire 28-22-1380
Prop - 8" x 3.8" slo flyer
Battery - Power Series 11.1v 600mAh LiPo 25c -> the current manufacture spec rec. wants me to use a 11.1v 340 mAh 20c. I'm not sure if this would be cause the issue though.
ESC - Silver Series 8 amp Brushless

So as you can see, I'm stumped at this point and any input would be appreciated!

Thanks a lot guys

John

The SAFE receiver is in beginner mode, it activates when it sees throttle input, that's why it doesn't do it prior to throttle input. You have two options, ditch the safe rx, and get another one, or figure out how to switch modes. Also, if you keep the safe receiver, make sure all the gyros are correcting in the right direction. It would make for a really short flight if the direction of correction was reversed. Personally, I'd ditch the SAFE receiver....

I think you're correct, I can change the settings with ease on the safe RX but it still wont let the elevator point straight down. I went to my apprentice and noticed this same thing was occurring.. So it sounds like my plane is flight worthy, but just wont reach peak performance because of the safe RX.

Just be sure you double check the direction of the gyro correction. If it corrects in the wrong direction, it can lead to a lawn dart pretty quickly! You'll be doing some serious fighting! I put the 635 out of my carbon cub into my T-28 and didn't realize the ailerons were backwards. Fortunately, I got it back on the ground in one piece, but it took some really careful flying to get it on the ground.

I made sure to place the safe RX just right and took extra precautions to ensure it doesnt shift in flight either. Hopefully it works out, I believe it's a bit heavy for my model. Thanks for the advice!
