I like the idea of something for thos lazy summer days, it would make a change from the adrenalin rush of EDF !

Io, is the no-load current. This represents the minimum current required to turn the motor itself without any additional load. It is essentially the amount of the applied current which does not contribute to driving the load. So if you have an Io of 2A and you are running at 20A, effectively only 18A of that is driving the propeller, the other 2A is just turning the intrernals of the motor. Rm is called the "equivalent resistance" or "terminal resistance" of the motor. This is basically the internal losses inside the motor due to the wiring in the armature. Rm is a constant which represents a loss of power due to imperfect materials. The lost power turns into heat. I've created a spreaddsheet that calculate everything you need to know from some basic inputs if you contact me I'll send it to you  James

Some of the Hong Kong Shops are now advertising in the UK mags, I've ordered lots of motors, ESC's and Lipo's from a particular shop without fault, in fact some of the Lipo's have proven to have better performance that those costing double ! I do however support my local shop for everything else as the personal element of looking in the box is important to me before purchasing. As for the numbers on the motors the only ones that are important are the KV, IO, RA and max voltage, you can then work out the rest.

A multiplex big lift mark 1. The kit didn't scrimp on the balsa, everything was sheeted with 1/8th, the basic problem was the design, the body wasn't long enough for the wingspan, no matter what you did it came in heavy.... no wonder they soon released mark II !

THe following e-mail arrived on Jan 08 regarding this fine kit ..... Dear Aeromodeller, As soon as 2003 we agreed with Benedikt von Arx, Beat Eichenberger and Daniel Eichenberger to develop the series version of their 1:8 Semi Scale Hawk. Sales start was planned for early 2005, however due to industrial projects we had to set back this date several times. In the past two years we generated further capacities to produce the Hawk. We would like to announce the sales start for the Hawk for January 2008. Please find more information for the Hawk kit at: www.schuebeler-jets.de. The right fan drive for the model is the DS-51-DIA HDT with Lehner 1940-12 and Jeti Spin 77 Opto on 2 x 4S 3800HDHE LIPO`s..

Safe to say that with many mouths to feed I'll not be purchasing one but will watch in anticipation of a few doing the circuit this year.
