To Find Channel Number from Frequency
1.Let say my frequency number is 35.150
2.Take the last 3 digit number but in hundred decimal (15)
3.Add 21 to the number (15+21=36)
4.Divide by 2 (36/2=18)
5.So the the frequency of 35.150 will give u a channel number of 18
To find Frequency Number from Channel
1.Say your Channel is 53 and the band is 72Mhz
2.Times the Channel number by 2 (53x2=106)
3.Minus it with 21 (106-21=85)
4.So the frequency number is 72.850
this procedure or calculation is meant for those the normal mHz radio. For Spektrum or 2.4ghz radio we dont have to check the frequency, 2.4ghz is free freq clashes, glitch free and unlimited range of flying. u can put on a camera and fly until u lost the plane hahahha
for me i'm using Spektrum DX 7 2.4gHz.......
DX 7 is used by Alan Szabo Jr, world champion in aeromodelling.... that's why i choosed this radi (although i dont even know who he is)
here is about the spektrum technology or 2.4gHz system
* FASST is DSSS with fast channel hopping, not FHSS, and has frequency redundancy
* Spektrum DSM/DSM2 is DSSS with frequency, antenna and spatial redundancy
* XPS is DSSS with as-needed channel hopping with an element of frequency redundancy
* Assan is DSSS on a single channel
They all work. Certainly both FASST and DSM/DSM2 are well proven in the field. XPS too now has plenty of users and seems to work well. Assan is too new to tell but technically, has no redundancy features so probably not a good choice for large or high value models.
All Futaba Tx from the 6EXH through to the 12FG/12mz/14mz (except in G3 mode) have design factors that mean their CCPM performance is poor compared to the DX7, X9303/DSX9 and a number of older non-2.4GHz systems too. Technically this is clear from bench testing. Anecdotally some people say they can feel the difference and others don't. I would be reluctant to buy a system with worse performance if another with higher performance meets all my other criteria.
FASST currently has only two Rx available, 6ch and 7ch. JR/Spektrum have five 6ch Rx (from 2g to 12g), one 7ch and three 9ch all currently shipping. Futaba will catch up in time but for flexibility in Rx choice, Spektrum is way ahead.
Only the DX6i, DX7 and X9303/DSX9 have ModelMatch which prevents you from attempting to fly a model with the wrong model memory selected. This is a very nice feature.
Unlike the DX6i/DX7/X9303/DSX9, the 12FG is not an integrated 2.4GHz Tx, it is a modular Tx.This means you can swap between a synth FM module or the 2.4GHz module designed for the 14mz. it also means the antenna is mounted on the module at the back of the Tx, not in the normal Tx position. Some folk don't like that.
The 12FG is very sophisticated and dripping with advanced features, even ahead of the X9303/DSX9. If you need 12 channels or the advanced features then it looks like an impressive Tx. The X9303/DSX9 is a high-end Tx with many advanved features and more than most pilots will ever use. It has Heli/Plane/Sailplane model types. The DX7 is a very capable high-end sport radio with Heli/Plane mode types. It has all the features that I think 90+% of people need but then I only fly helis and simple planes.
Given that the 12FG is about three times the price of a DX7 and maybe double the price of the X9303 and that FASST Rx are about double the price of comparable Spektrum Rx, if money is a factor then the choice is easy.If money isn't a factor then compare the features and do your best to get a chance to physically hold the Tx. Then choose the one that has the features, flexibility or feel that you prefer.
For those who are interested to join in RC aeromodelling can let me know, i'll give u the links to forums which i've been joit and active since the beginning of my carrier as aeromodeller hahaha
