With 12 control functions, the mx-20 HoTT lets the advanced RC model builder to control nearly any model. The use of Graupner HoTT 2.4-GHz transmission technology ensures great functional reliability through bidirectional communication between transmitter and receiver, with integrated telemetry, voice output via headphone output, and ultrafast response times.
The transmitter has 24 model memories. Simplified programming using touch keys. A contrast-rich, 8-line, blue-lit graphic display ensures perfect display of all setting parameters and telemetry data. Telemetry data and additional model memories can be stored on a micro-SD memory card. (later after update)
The channel signal is resolved at 12 bits in 4096 steps, thus providing extremely sensitive control.
USB connection for reading out and storing model memories and for firmware upgrades.

Microcomputer remote control system with state-of-the-art 2.4 GHz Graupner HoTT technology
Bidirectional communication between transmitter and receiver
5 different languages (German, English, later French, Italian, and Spanish) possible via software update. For availability of the respective language, see Download area.

Pris for sett.............. Kr.3700,00


Settet inneholder:
Graupner HoTT mc-20 microcomputer telemetry sender med NiMH 2000 mAh sender batteri, Graupner HoTT GR-24 mottager, og 200mA lader for sender.
Alle kabler for softvare opp dateringer, og et Micro SD kort følger og med.

Graupner har kommet med en praktisk senderpult i Plexiglass for hele MX-HOTT serien.
Senderen ligger veldig stødig og med en fin vinkel.
Sammen med lange stikker 33000.3.
Så blir det en fullgod senderpult løsning.

Vi har valgt og bruke Smart boks 33700 sammen med denne senderen.

NB!! Det er ikke behov for bruke smart boks for og se telemetri dataene!
Men med en smart boks så har en mulighet for og ha denne som et separat disply,

Da har vi telemetridataene overført til smart boksen. Og de vanlige sender programeringen i sender displayet.


Når vi bruker senderen til små modeller, eller F3K (handkaste seilfly),
Så er det mest praktisk og ta senderen ut av senderpulten,
skru på korte stikker, og holde den i handa!

NB. senderpult er ekstra.
