Does anyone know if the GY401 will work OK with the Spektrum DSP75 servo?

I know it won't work aa well as the recommended combinations but being at extreme altitude I'd like to keep the heli as close to the design weight as possible.
I'll already be adding +16g with Gy401(27g) instead of the stock G110(11g) and the recommended servo's like the 9257 and 9650(?) are about 20g heavier than the DSP75.

Just thought someone with more electronics/heli knowledge than I might know.

Spekturm DSP75
Programmable Digital Sub Micro servo
Torque: 19.0 oz/in @ 4.8V
Speed: .11 sec/60d @ 4.8V
Weight: 7.5g

Thanks.

The problem I had with this combo was that the tail had a lot of rebound after a piro. If you really think weight is an issue, get the programmer for the DSP75 and make a TR servo. I will work better with the 110 and you can really fine tune the setup.

By the time you get the 401 working with the DSP75 it won't that much better than stock. You really need to have a servo that's powerful and fast enough to keep up with the 401.
