400HeliPilot Senior Heliman Location: Boca Raton, Fl - USA
| Fleet of K-27 (E-sky Happy Baby coax), Lama2, Blade CP, HB CP2 x2, and Shogun x3.
The Happy Baby ($109 full kit, free US shipping) had a terrible rotor/blade so I put in the Lama2 inner/outer shafts/blades/grips/swash (cheap). It has a great frame, super COG, really strong landing skids. Have removed the terrible body, stole the Lama2's tail for it and it's cabin for it.
The Lama2 ($120) got a scale fuse & super skids...
Both Coax run on 2S E-tec 10C 700mah batts (6) & full seperates, PG-03 gyros, dual blinking, tiny, PP-5B 2S LiPo cutoff ESCs, tiny DSP 4ch RX (cheap). The 180 motors are mixed on an Optic 6 TX, revo-mix is used to keep the helis totally straight in altitude changes.
I've heard the Lama rotor system holds up better in crashes than BCX (the flybar just pops off). Typically BCX is more calibrated 4in1 from the box (if you keep it). Both heli parts are produced on the same line. Nothing too wrong with CX, but most prefer the Lama2 rotorhead, as mentioned Lama parts come from the 'net, cheap too.
A tip: Grab a black sharpie/marker and color the 180 motors all black, it'll lower the motor's temp 20-30+F (I've verified this; like car radiators). Teflon-oil works real well on the bearings/shafts. Adjust motor gear meshes for easy spin rotors. Batts go longer, motors stay cooler.
These modded helis can fly fast & furious, go hands-off without drift from the PG03 gyro, & were cheap. Money saved on E-sky helis, got extra Lipos so no waiting (2 helis, $50 MK II charger, etc).
Easy to add brushless, but not cost effective. Johnson 180 motors are dirt cheap and last awhile. |
