Thanks, I'm currently using the MX22 with a spectrum module. Love the menue layout etc, so if that's the same it would be nice, with the added benefit of built in telemetry. I can't find anywhere if it has model match to prevent throwing a model off on the wrong memory.

I think only spazzy has model match.

From what I've been reading on some German forums (through google translate) it appears that it does have Rx to model memory match.

Any way it's ordered now along with some receivers and a nice shiny alloy case,

Thanks T9!

Hi Adam,

I have been using the the Graupner MX-16 for over 10 months now. Very impressed, no problems, no brown out's, compared to another well know brand.

I was that confident in the HOTT system, I converted my Graupner MC-24, same again no problem at all. Ask Dave Rumble I flew his Extreme for 2 months, with HOTT system installed.Each receiver is coded to each model memory, so you can't select wrong model and try to fly the model.

The telemetry is built into the transmitter and receiver, real time battery voltage and signal strength, if losing the signal the transmitter will warn you.You can even download information from the last flight, to see battery voltage and signal strength and quality.

With the GPS module, the information can be imported in google earth, including speed and altitude.

Enjoy.

Its here!

1st impressions are good, nice little touches like pre set adjustable elevator curve in the crow mixing, and the telemetry voice is fun, she told me i had 100% signal and rx was at 32 degree in the living room, so i put the rx in the fridge :D and still managed to have 90% signal strenght and temp dropped as expected, signal was impressive through a fridge and a brick wall :cool:

British voice is on the memory card which loads to the tx upon selecting british in the menue.

Programming is a walk in the park, menus are the same as my MX22 but with a few nice added extras.

The voice only works through a head phone socket on the rear, so i bought a nice little amplified speaker for it. so ill now have the options of headphone, speaker or just beeps for the telemetry.

hey btw since you got yourself a 6000mah Li-Io. Did you realize any shortage in signal range? Or any differences or problems of any kind? I am asking because of the lower volage compared to the original NiMh
