Micro Thread Index (the best place to start)
This is an experiment, a thread of threads. You post what threads in indoor and micros you think contain info so useful that they shouldn't be forgotten/lost.

I'll decide if you're right (;) ) and add them to this message at the top of the thread and try to group them etc, this will keep this thread super short and easy to reference.



show off those ar6400 planes!

Post your models for the Kyosho/Parkzone RX here

Plane Thread Index



17.5-inch Chilton DW1 by Graham Smith. This thread has downloadable pdf files with construction details and templates. The plane is built from paper and foam but could be adapted to all foam, tissue covered foam, etc.

Come and get it - MicroMoth plan!!

MicroPitts plans are here

Profile Guided Mite plan

My new chariot car powered Bit Bipe

Quick Junior plan and construction article in the December 2003 Inside Story. The QJ is a nice stick plane for pager motor power and actuator control with a typical weight of between 15 and 18 grams.

Sources of 3-Views thread. Sources of 3-views since these are where many micro semi-scale models start.

RC Car Conversions

Long thread with much discussions on bitcharger car conversions
Bitcharger conversion

Bitcharger stickies, threads created to show conclusions:

1. Working Bitchargers

2. Bitcharger TX mods

3. Bitcharger receiver mods

Included in the attached zip archive is an Excel spreadsheet with all my measurements for GWS props, and a thrust calculator. To calculate thrust at another rpm, enter your rpm along with the prop's diameter, pitch, and tconst from the measurements section.

If you have a prop that is not listed, you can try guessing its tconst by comparing to a similar prop that I have tested. In general, slowfly props have higher tconst than hyperdrive, and a higher pitch/diameter ratio also increases pconst (up to a point, then it decreases as the prop stalls).

Note that my tconst is NOT the same as Motocalc's tconst (which is calculated from power, not rpm!).
Download the zipped spreadsheet file below and use.
