Hey All, I was wondering what it would take to get a brushless set-up to reach the speeds of 80-90 mph ( a OS 25fx tweaked w/mousse can )) I have a half dozen or so smaller brushless set-ups, parkflyers, running 200-250 watts w/30 amp ESCs and 1000-2200 Mah 3s1ps, I know that I`m gonna need some bigger li-pos,ESCs and motors, I get alittle confused when crossing over the nitro specs ( rpm vs watts ) I pulled this off a website on a motor review, and the spit weighs in at 3-3.5 lbs.............Hyperion .25e Spitfire spinning a 10x10e APC prop on 4S 2200 20-30c lipo pack , with a 60 amp ESC. Whole setup works fantastic. Clocked the plane at 86 mph in a level pass against the wind with gear down. Vertical climbs are mind-numbing. Motor comes down a little hot because I'm riding it WOT at 40 amps, which is pushing the edge of the motor's recommended limits. I suggest using a slightly bigger prop on 3S or slightly smaller prop with a 4S setup like mine..............anyway I sure would like to do both Open-B and 2610 combat E-POWERED...I`ve talked to a few people about it, and they`re very concerned about a Li-Po fire, due to mid-airs. Hey thanks for all and any help.......oh yea also I should mention that they will WOT all the time ( 5 mins ) Well that`s how we do it with our SLIIIIIIIMERS [8D]
