RE: RE: RE: Electrified Partner ...plus
Kyle,
Thanks for the kind comments. It was great meeting you and getting to talk "electric". The weather was much better on Sunday and we got in 3 more rounds. Here are some of the results that I can remember,
F3A - 1st -Troy Newman, 2nd - Greg Frohreich, 3rd - Jim Woodward
Masters - 1st - Tony Frackowiak, 2nd - Jerry Budd, 3rd - Rusty Fried
Sorry, I can't remember Advanced and Intermediate.
Sportsman - 1st - Terry Hemmis (our local lady pilot!), 2nd - Kyle Mashima(I'll bring your plaque to MWE!)
Troy was having engine problems with his Smaragd and needed a complete score for the last flight, so he flew the Partner. He got one quick flight on it practicing Friday, so it was still pretty new to him when he flew it that last round. He put in a great flight and proved the effectiveness of the model in the F3A pattern. Maybe he will add some comments here later.

I'm not sure I would change anything in this model, it seems to be working very well. We did a sound measurement on it Friday using Troy's meter, and it measured 89 db, well within the limit. It may be an interesting experiment to hard mount the motor and see if anything changes, but certainly a little vibration isolation isn't hurting anything.
Krishlan,
Glad to hear from you. If you want to get together to fly just come on up sometime.
Will B.,
I did the R/C battery ejection years ago with an 1/2A Ace Pacer. Just turned off the TX and watched it hit. Oh well! I am absolutely convinced electric will take over pattern, there are just too many advantages.
Dean,
I wasn't using the UBEC in the Partner yet, luckily, as I ejected both 5s4p's in my little stunt. That's removing 3.1 lb all forward of the CG and the thing was still controllable. Since the new TP cells about to come out will pull another 10 ounces off the battery system, I don't think I'm going to bother to use the UBEC. Frankly, I want this model just a touch under the limit. I really think we can get these things too light.
BTW, the UBEC is a switching regulator. I have installed one in my H9 Funtana, no problems so far. But I think I'm going to stay with a separate R/C battery, at least for now.
The stall/snap characteristics are excellent. In the spin, I enter with high rate elevator, and I have to reduce that elevator after the entry, or it will go into a sort of weird flat spin. With the reduced elevator after entry it is a very stable, slow spin that stops instantly. The snaps couldn't be better. There's a vertical climbing inside snap in the P-05 F3A pattern, and when I've played with them, they are great. When Troy flew it on the last round, he absolutely nailed it.
Concerning the vertical placement of the batteries. That is the only real trimming, other then control gains, that I've done. With the original mounting of the motor batteries, as in the posted pics, the model had a slight pull to the canopy in the vertical lines. I lowered the batteries 1", and instead of stacking them side by side vertically, I laid them down horizontally. This lowered the vertical CG and now the uplines are perfect. I think if you mount them very low with that Supra-Star you may have a pull to the LG.
Now to get an Excellence framed up for Jerry so I can start on my next one!
