Flysky it4

請ching比D意見

not bad

Any detail for this control thanks

GT3B/C就多人講,呢支出左咁耐,國內同香港都無用家講過,都諗到會係點

I am using FS-iT4
It is not bad actually.
The initial cost may not be attractive (FS-it4 ~RMB800 vs Sanwa MT4 ~HK$1350) but if you have to buy more receivers, then the additional savings (FS-iR4 ~RMB 100 vs Sanwa R461 ~HK$600) is apparent.
Performance-wise, I am not experienced enough to note a huge difference with FS-GT3B, just that I feel that it don't have the lag feeling of FS-GT3B at a distance.
It also has a rich set of features with some nice touches, eg. 4 modes timer, auto power off (I always forgot to turn my FS-GT3B off and dried the battery) etc.
Telemetry features - battery voltage, temperature, speed (magnetic) & speed (optic) sensors are available - certainly I think the YR speed sensor for MT4 (which can detect magnetic field change from motors) is much more convenient.
The look is ...... subjective. While it is certainly not attractive but it is not that bad actually.

WHY MY IT4 SOMETIMES HAVE A BUBU SOUND( I THINK A WARNING SOUND) WHEN STEERING OR RETURN TO NETUAL. ANYTHING HAVE TO SET UP?

low voltage warning?

我gt3c不到20咪及反应遲頓垃圾。

iT4 is a totally different model with GT3B or GT3C.

I also have a GT3B with similar problem (short receival range) before and fixed after re-soldering the antenna on the receiver.
Do note that the antenna wire on the receiver is very very thin and you have to handle with extra care.
On the other hand, to avoid the hassles, you may just buy another receiver for HK$70 or RMB40
I think the major advantage of Flysky is the cheap receiver price (compared to several hundred dollars for Futaba and Sanwa receivers).

Bobby ching 想再請教接收是否需要另外比電，今日再試發覺當轉左/右時支控右上角RX變紅跟住呠呠響，同埋ch3同ch4系冇steering mix時會走埋一邊，set左好耐都set吾到

我估計你的接收電壓不足, 我支正常有6v.
如你再有中途停車時, 請檢查電池電壓, 因我亦曾有中途停車現象。換電池後問題解決。

Thx for your reply
