With respect to another members previous SC b/less conversion and any discussion about any significant change in thrust angle relative to CW vs CCW motor rotation relative to using a left-handed vs right-handed prop ... it probably isn’t all that big of a deal … EVEN if the stock 480 brushed motor (w/gear driven prop) on the DSM & LP is wired for CCW rotation so the prop spins CW. Being it’s a brushed motor we’d assume it’s wired for CW rotation in which case the gear driven prop is spinning CCW and the stock prop is actually a left-handed prop or pusher prop that’s been adapted for tractor/puller application. However, the motor torque to the airframe is still CW being that the brushed motor is rotating CW.

IF the gear driven prop is spinning CW it means the motor/torque is rotating CCW. If this were indeed the case then there might be some justification for using a left-hand pusher prop (converted for tractor/puller application) on his direct drive b/less outrunner wired for CCW rotation. However, the SuperCub is considered an inexpensive 3-channel beginner plane not a pylon racer or aerobatic plane that requires precision handling by the pilot … in which case(assuming the SC were a precision aircraft) when changing the motor's torque/thrust angle from CCW to CW rotation, then it may make some sense to use a CCW rotating 480 inrunner with pinion and gear drive setup … ASSUMING THE STOCK 480 BRUSHED SC IS ACTUALLY WIRED FOR CCW ROTATION..

The REAL bottomline question here is: Is the difference in flying enjoyment (3-channel) worth the extra time and expense to convert/modify to b/less even if you can buy most of the items via HK and rob some of the parts from another crashed plane.

Lipo manufacturers have up to three different ways of referencing the three dimensions. ParkZone references the 15C 1300mAh according to its position in the SuperCub LP with relation to the plane’s dimensions of length, width and height as the lipo is positioned in the battery compartment. However, we sometimes think of the width of a lipo as being its narrowest dimension as apparently does E-flite; whereas many lipos are positioned in a plane laying down so the lesser dimension is sometimes referred to as its height as does Thunder Power’s method of referencing the lipo's dimensions. Other pilots/planes position the lipo on its side when the battery compartment is in a narrower cockpit location as apparently does E-flite’s method of referencing their lipos width & height dimension.

In order to get at least as much flying time with a b/less mod as with the stock setup a 2100mAh lipo is suggested. However, as you can see below the SC LP battery compartment will not accept a 4 inch lipo laying down. A modification opening has to be cut out of the battery compartment to allow it to extend upward into the plane. So, when referencing the relative dimensions of the Thunder Power 25C 2100mAh lipo shown below as positioned in a modified SuperCub LP b/less outrunner could be …

Was hoping by now at least one well-honed parkflyer might have offered the following advice ...

... A conversion from 3 channel to 4 channel with ailerons and even a steerable nose wheel is a better FIRST and second choice(steerable nose wheel) that makes more sense when it comes to improving a SuperCub's flying performance and improving your piloting skill. A brushless conversion should follow a second or third conversion priority, but even then the expense is better invested in another plane like a T-28 or other 4 channel as you're now ready to move on from the SuperCub to an intermediate or advanced plane depending on your acquired piloting skills and more specific flying interests.

The steerable nose wheel (second choice) was an inside joke for those more advanced and elite flyers that may think the following HZ conversion is only practical for those SuperCub owners that don't plan anytime in the not-so-soon future on upgrading to 4-channel plane, but do want to soon learn 4-channel with ailerons in the not-so-distant future. They also want to convert to brushless (because all their buddies have outrunners) and they are satisfied spending the extra money on just this one plane (that goes faster with some aerobatic flare) with no immediate plans of upgrading to a ParkZone plane like the T-28D(or PNP) or an E-flite like the Apprentice 15e.
