Default RE: Are Hitech servos problematical with Futaba 2.4Ghz

Would any of Hitec's DIGITAL servos cause a problem with the R6008HS receiver in "hi-speed" mode?

Dear Bill Baxter:

Dave "the PIPE" here...as I've always constructed all my own RC transmitters, due to needing to only use "knobby" single-stick units for flying, I've built the first of two knobby radios for 50 MHz Ham band usage (I've been "KA1ABG" since 1978) based on the encoder unit created by fellow Ham licensee Gordon Anderson, whose webpage is at http://mstar2k.com/ , and with photos of my very first MicroStar 2000 (abbreviated as "MS2K" ) knobby radio based on that amazing encoder viewable at http://groups.yahoo.com/group/MP8K/p...87349/pic/list .

By setting the sync pulse timing at 400 µS, and using the "MS2K" default FM shift polarity of a positive shift (what I think is what Futaba uses all over the world, except for US/Canada 72 MHz) the MicroStar 2000 encoder has been used successfully with the TM-8 FASST module before in owner-built RC transmitters, and I'm eventually planning on using a pair of TM-8 RF modules (one for each "knobby box" ) as the signal-sending component of a pair of future owner-built MicroStar 2000-based radios, specially set up for "SpredSpec" 2.4 GHz flying needs, and which, of course, will both be "knobby" single stick units.

I had thought of using the R6008HS Futaba FASST "high speed" receivers, as I'm quite sure you've heard about the problem of "overheated" Futaba FASST receivers, like the earlier R608FS units, sometimes losing their lock on the signals they were locked onto when the receiver's temperature exceeded 59ºC (138ºF) inside of a model aircraft, and I have been hoping that the R6008HS receiver was one that HAD beaten that "59ºC" problem.

Now, for that "high speed" mode...where I DO use Hitec servos myself, and they've got a good line of digital servos of their own, I was wondering...would the Futaba R6008HS receiver's "high speed" channels, that is, channels 1 thru 6, work with a different make of digital servo besides Futaba's own ???

I've had in mind the Hitec HS-5245 digital mini myself (at http://www.hitecrcd.com/products/ser...hs-5245mg.html ) for a 42" (1.07 m wingspan) Bücker Jungmeister's control needs, and a plane like that, for Saito 40 four stroke power, would greatly benefit from the combo of the R6008HS's "high speed" mode, coupled with the HS-5245 programmability from one of Hitec's own servo proggers, when I finally can afford to go "SpredSpec" as well as my usual 50 MHz flying.

Hope to either get an answer here, or by directly Emailing you about it...

Yours Sincerely,

The PIPE !
