what prop for a Reflectionwith rimfire
I have a reflection/rimfire/bl8 esc/ and 640 3cell lithium. the recommend 9x3.8 prop will not hove the plane. The 10/3.5 that comes with the brushed motor will hover at 1/2 throttle. I don't have a amp meter, but will this prop pull to many amps on this set up??? What is the proper prop?
PS My plane is a few ounces heavy......i was very generous with the glue

RE: what prop for a Reflectionwith rimfire
I have the same setup with my GP Extra 300S and it flies fine and hovers with the 9x3.8 prop. I haven't tried it, but I also bought the 8x3.8 to try. I also didn't try the 10x3.5 that came with the plane. I was told that the brushleess motors don't have the torque compared to brushed, but the RPM's are greater and therefore a smaller diameter prop is necessary.

RE: what prop for a Reflectionwith rimfire
to fly a bigger prop than a 9-3.8 on the bl-8 is not the best idea, may fry it, instead id save that for another plane, and go with a silver series 12 amp, and then a 10-3.8 prop should be ok. also for next time fo easy on the glue, i build them using foam safe CA only except for a little six minute epoxy for the motor mount, If its over 10 oz. it heavier than it should be mine I'd imagine is around 7-8(its a Radix) and hovers at half throttle no prob on the rimfire, bl-8 and 9-3.8 prop. so I'd weigh it first and go from there.

RE: what prop for a Reflectionwith rimfire
Thanks, silver 12 it is......The plane came in at 13 ounces including battery. Gorrilla glue.....but it is a very stong foamy...... one more question....the weird thing is the 10/3.5 is turning more rpms than the 9/3.5 and after 5 minutes with a 640 3 cell lipoly, the motor, battery, and esc was just barely warm, not even close to hot. The 640 3 cell on the 10/3.5 was drained down to cutoff right at the 5 minute mark of mild flying. My Astro 109 put back 450 mah back into it. Does this sound about right (sorry, kinda new to electrics).
I tried a 6 minute flight with my TP 900 3 cell pack . Motor, esc, battery, barely warm and the charger only put back into the battery 340 mah???????? I think I'll buy a couple of the TP900 along with the silver 12.......thanks

Yeah, def. if your happy with those flight times, mine gets 10-15 minutes, 13oz. is a tank for that plane, not saying it wont perform fine, its all preferance, my Radix is light and just floats, aileron only rolling circles, That 12 amp esc, 900mah battery will be kickin some seriouse you know what when you finally get a new plane after this one wears out as all foamies due. If you want another reflection tower has some box damage only ones on there site for a few bucks off, also the flatana are decent planes.

Run a 3cell and a APC slowflyer 10x3.8....works perfectly. Its the smoothest and best power option Ive found. Seems to have just the right "umph" for the rolling harrier circles.

No, the Radix is an Ultrafly plane, Thier competition inspired one, full fuse, which is very rigid. 1.3mm depron. very light and also flexible, flies great.
