I removed the battery tray and she seems to balance out. I also added the rigging. I don't disassemble my bipes as it is just too dang much trouble. They take up a lot of room in my den but so be it. I also placed the RX out of my Apprentice S 15E in it. I have several bipes but have not had the chance to fly any of them as yet . I have a great flying field but it is far too rough for a tail dragger other than the Timber and the Commander mPD with larger wheels. As you can see, I am quickly running out of room in my hanger. I also included a pic of the battery without the little tray that seemed to be more trouble than anything else. I added a 3" piece of balsa on the cockpit cover to hold it in place. I know it's not much but it seems to work. Peace.Originally posted by Hiflyer View PostAttached FilesLeave a comment:

Thought about adding wires myself, so I will see how ya go about it. I would probably reserve that for a scratch build.
One of our club mmembers remarked to me how I fly it so scale like - but I use about 1/2 throttle a lot, and rare that anyone compliments my flying skills being the new guy at the field.
it is definitely one of the more popular planes at the field and saw another brand new one this week - enjoy!

I recently reviewed this plane for RCG and came to the same conclusions that you did re: CG. I included some photos of how I added birdshot to the bottom 2 cylinders of the dummy engine. I love the way it flies and am really enjoying it. It is such a good looking model that I am going ahead and doing some additional detailing (as you did) to the motor. Next I am going to install flying wires as well. Maybe the added drag will aid in slowing it down even more for a scale flying speed.

I kept the battery tray, but was able to secure it forward of the tray end and it touches the motor mount - still needed weight.Originally posted by TiredIronGRB View PostLeave a comment:

If you take out the battery tray you can move the battery all the way forward and get the correct CG without adding weight.Leave a comment:

PT-17 from eFlite
Got this when they recently marked them down for a short while and glad I did. Such a sweet flyer, and while it is true it was necessary to add 1.6 oz. in the dummy cylinders with the 2200 battery, That said I'll bet a 2600mah may require removing that weight. Balancing on your finger tips may be ok for a quick check at the field, a maiden flight should be set up on a stand and within the range with just a touch nose down. Be as precise as possible, turn off ceiling fans and A/c . And don't, don't don't even think about flying a tail heavy airplane.
The 6000 lb. airplanes I fly regularly have a CG that only moves about 12 inches within the widest parts of the envelope. Model planes this size have a scale range +/- 1/4 inch, which is approx the diameter of the pencil erasers I balanced on - now I use aluminum tubes with round plastic caps fitted into a base that clamps to my work bench and has adjustable width. Go for the center of the range and then add a few grams more to just get the nose to tip down a bit. I recommend steel bird shot sometimes mixed with epoxy, but usually just snip a finger off of a latex glove and fill it with shot - easy to get 1.5 oz. in each one and they can be wrapped with electrical tape to prevent rupture and secured in the model.
Now my favorite flyer, I just want folks that might consider buying one, not to be dissuaded by the negative reviews she's very docile a quite stable if you follow the directions which are spot on if you read them carefully, don't try assemble it with force, and expect to make some fine adjustments after the first flight - they will be small, but have big effects.
FYI, I got the BNF version, but a club member bought the PNP and put the Eagle gyro in place of the Spektrum equipment- flies beautifully and in fact it's his fault I decided I had to have one. Glad I waited a bit as they marked them down for a few weeks.
In fact, I think I will plan on taking it to work to fly afterwards on the way home.
