Ok, so I've been flying this little parkzone as3xtra for two indoor seasons now. I've had a lot of fun and with the electronics, I can actually fly 3D! Well, they are not good structurally. I've been wanting to upgrade it for quite a while because it hardly has enough power to really do 3D. You can go hard about the first 1-2 min of a GOOD battery, but after that, it's pretty limited. I've been converting the rest of my micro fleet to brushless this year and now the only brushed plank I have left is the as3xtra, but I know going brushless on the stock airframe will do nothing but rip the wings off since I almost did that with the stock motor!
SO...a build is necessary. Less than a week ago, I set out on the internet to see if anyone had plans so I would not have to trace my own. Yep! Bonus! I grabbed them and headed to the printer and got a couple copies printed out full size. Next, off to the dollar store for a couple pieces of foam board and...UNINFLATED BALLOONS!! I cut out the print, traced it on the board and got to work. UGH! Tedious! LOTS of cutouts! All necessary though.
Old and new. The stock plane FLIGHT WEIGHT is 35g! I was hoping to get it in at 50g total flight weight and we ARE going to 2S, with early plans to generate 90g of thrust.
It was about this time I had to get another order into HK for more micro elements. One of the hardest pieces I have sourcing is prop savers for 1.5mm shafts! They give you a VERY nice one with the AP05 motor, but I can't afford to buy 10 of those at $15 each to just get prop savers! I have that motor on my T-28 and it rocks, so that was one of the motors on my list...along with a few ESCs and other necessities for working with micros.
Well, the covered airframe came in at 34g, so I thought we were on track. Before you say something about the control surfaces...Look underneath the fuse! They are there, they just are not mounted yet.
Well, the electronics are always a trick, aren't they? It didn't take me too long to get the as3x brick in brushless mode, it is really the same as the older parkzone rx, no big surprises. I got some of those BLheli loaded ESCs on clearance for $1.99 but haven't got one of them to work yet! I have one more I might fool with, but that was $6 WASTED as far as I can tell. They spun one of my three motors, but choppy and it was not going to run. I went on with the HK 15A 2-6S ESC and that ran two of my three motors...It did NOT spin the AP05?! Go figure... That's the motor I really wanted to put on this. They claim it will pull 110g of thrust? Oh well, I'm down with the Turnigy in the end. I'm going to try it on a 5" prop first, then probably go back to a 4". A lot of these 5g suggest a 3" prop, which is just not going to cut it. You will notice I crowded everything up to the front. I hope the CG is forward enough. If not, I'm going to have to start cutting the lower rear fuse off, maybe filling in with a couple of crossed CF bars (tiny ones).
