I intend to use an anodized aluminum mount (I have one picked out already). I'll polish the "copper" firewall to a mirror finish with some metal polish. It'll look so cool I might have to leave the cowl off. |

I don't know how to program these, but apparently this is the idea on PPM to PWM conversion using a PIC:
I found a PIC programmer for about $50, so I guess if I have to do this myself, it's not really cost effective So, DaveMc, you got a taker here if you decide to put out a few "extender" boards!! |

Test Results
Stock SC using a 7 cell NiMh through my wattmeter, on the stock 10x8 prop
1/2 throttle... 3150 rpm... 8.1v... 4.5 amps... 36 watts Full throttle... 3750 rpm... 6.9v... 7.9 amps... 54 watts Using a ThunderPower 3s 1320mAH Li-Po: Castle Creations Pixie 20P ESC GWS 10x6 DD prop Full throttle = 6700 rpm Volts = 10.9 Amps = 8.4 Watts = 91.3 Only a half amp more current is being used. Watts went from 54 to 91 This will be perfect... I'll have the power used at 'cruising speed' once I take it out to the field. Chuck |

If you do want to get a programmer, I would recommend this one on eBay (high quality) which you can usually get for $25 + shipping when it is not 'Buy it Now': http://cgi.ebay.com/PIC-KIT-2-COMPAT...QQcmdZViewItem If you want something that is a programmer and an in-circuit debugger, this is a good one too: http://cgi.ebay.com/MPLAB-ICD2-ICD-2...QQcmdZViewItem The prototyping board I used was this one: http://www.pololu.com/products/pololu/0331/index.html You can get the 4 pin header connector type used on the HZ RX XPORT here: http://www.sparkfun.com/commerce/pro...oducts_id=8231 dave mc |

Dave, thanks!! The SC I got needs some work, so it'll take me a while before I get to try this... I'll let you know when I get closer (probably several weeks from now)... I'm not adverse to cobbling up something myself, but obviously would love to save the work if you're "close" to finishing the pcb when I'm actually ready to try it out
have to say, I'm a newbie in RC and this board, but there are some extremely knowledgeable and helpful folks around... real glad I bumped into you folks! |

I'm in the process of installing a Park 450 890kV in one of my SuperCubs right now. This motor willlllllllll have all the power I need! 14 amps (constant current) x 11 volts (3s Li-Po) = 154 watts! Chuck |
