Hello All.

After a test flight I can tell that the 450 th works remakabely well on 4S.

I tried it on 4S with a 10t pinion, 315 woodies. My thottle curves were between 80 at 0 pitch and 97% at full pitch 10° (i don't use governor). The headspeed is a strong 2600+.
I made a quick amp draw reading :

In hovering amps were about 8-10A, in full pitch it was around 18-19A.

I only made a series of climbout (cause i was not so confident in my align 25A to support this setup, you don't want to have an ESC shutdown while doing a flip ). This was with an older pack that is almost completely dead. I still had 6 minutes of good climbouts and hovering with this pack. I cannot imagine what would be my flight time and power with a new solid 4s pack.

There was no strange noises, not annoying vibrations coming from the motor, The only noises were the sweet zzzzz, and fllllll of the blades and transmission.

Hi Pitounet

What is the capacity of your older pack. The head spped should be more than 2800 for 450TH using 4s set up, isn't it?

I got about 2900 with the 450th and 4s with the 10 tooth pinion.

Hello chiu.

I tached my headspeed in 4s,

I have more than 2800 rpm. My older packs are E-PRO 2100, but they are really worn out, I cannot even do a single flip with them in 3s and I cannot fly more than 30 seconds of hover in 3s. That is why i decided to try and make a 4s pack with them.

450th on 4s is simply excellent!!!!
