To all Scale Pilots,

I am contemplating of finishing up my TT E620 and put it into the TT UH-1Y Huey fuselage. I am planning on having this Huey runs on one TP 6 cells lipo 5000Mah. Currently I have the following items for the build.

1. TT E620 kit – already assembled;
2. Scorpion HK-4025 1100kv brushless motor – not yet install;
3. 3 JR DS8311 digital servos for cyclics;
4. Futaba GY502 gyro ;
5. Futaba S9254 for the tail;
6. Ultimate BEC 6V;
7. Spektrum AR 9000 DSM2 Rx with only one sat; and
8. A complete packet of navigation lighting system

Items needed to complete the build:

1. ESC – What kind do I need for paring with HK4025? I am thinking of buying a used, but in good working order Castle Creation Phoenix HV85. Is this combo okay? If so;
2. Motor Pinion - What motor pinion and tooth are appropriate for the HK-4025 and the CC HV85?
3. Another sateline for the AR 9000
any other suggestions and guidance are much, much appreciate it.

Be careful to have a very free tail control rod. The S9254 is not compatible with any binding here. I sugest a more powerfull servo, even a beat slower. I use a Hitec on a sclae heli i have. Around 6kg torque at 4.8V and 0.10s/60°. By far fast enough for scale flying and much more reliable than the S9254.

About the ESC i think a 100A is a better choice in case of since you would'nt have much air flow inside the body. You may use a 85A but with a small computer fan blowing air on it during the hot season.

You also don't want to run 6 volts to the 9254 servo, it will eventually fry it. Dont ask how I know

I don't always fly helis, but when I do I prefer to fly scale.

Sorry it has been awhile since I first post these questions, now I have secured a CC ICE 100 and need to know what kind of tail servo that I need to pair with all other electronics I have listed for my soon to be built TT-E620 and this will goes into the TT UH-1Y scale ship. Thanks all in advance for guidance and suggestion.

I have the the same heli and the same fueselage. I use GY401 with S9254 and I don't have any issue with it. One thing I changed on the build is that I mouted the servo on the heli air frame where it suppost to be in a pod and boom confirguration. Then use a long flexable push rod and guide to control the tail rotor.
