I have a JR8301 that will not develop full power
I need help. I have a JR8301 programed in the glider mode the spoiler as the throttle. It seem not to work properly on 2 different motors. An Astro 010 with the standard controller and a Mega 16/87/7 with a new Castle pixie 10 9x4.7 prop. I am using new full charged 7.4v 1700 mah Li-Poly. The Astro 010 is on a Tiny weithing 10oz. with 9x4.7 prop. The Mega motor is on a WingWarrior, a very light foammy. Both planes stagger in to the air and are hardly flyable. I watched a Demo pilot hover the Warrior at half throttle at the NW Expo a couple week ago where I bought the setup.
I have set the TRVL ADJ to +/- 150 for the spoiler/throttle.
I am flying a Pigi this way and it appear to develop full power in this setup. Most of my flying is in full house TD ships.
Any suggestions?
Thanks in advance,
John

RE: I have a JR8301 that will not develop full power
You're probably trying to draw too many Amps from the 1700mAh LiPoly. None of the mainstream LiPoly manufacturers I know of (Kokam, E-Tec, Thunder Power, Irate, Tanic) make 1700mAh cells.
Are either of these motors geared? The Astro definitely can't turn a 9x4.7 direct drive.
Which Mega are you talking about? They don't make a 16/87/7. The 16/7/7? Geared, I hope.
Are these the EXACT same setups you saw fly, or are they "sorta" the same with some poetic license?

Matt,
I have a 7.4v 1700mAh Platinum Polymer from Batteries America 2 cell (model 2LP1700). The Astro 010 is geared with a orange metal frame and the ratio seems to be about 3:1. The Mega motor is a 16/8/7 with a Mega factory Microgear and is 2.8:1.
I think the props were 9x3.8 or 9x4.7. The Astro prop came the the used model.
Any suggestions with this new information? I am wiling to change prop and or batteries to get them flying normally.
Thanks,
John

Matt,
I put a 3 cell 1500mah high discharge 3.4oz batt($70) on a 9x4.7prop. It flys fine and will almost hoover. I plan to add a rudder servo to my Tiny. I am pleased with the performance now.
I need to do more reading and studding about motor, prop, and batteries combinations. Volts, watts, and amps are foreign to me but I am learning.
Thanks,
John

Yep, sounds like your 1700mAh LiPolys were the older low-discharge type. Those Kokam 1500s will provide up to 12 Amps easily, but the old 1700mAh ones were probably struggling at 6 Amps.
