I'm just about to start building this kit and noted that the plan shows an OS 120 FS for the four stroke option but all servos are clearly marked Futaba S148. That rather surprised me as I'd have thought the S148 might not have been man enough for a 120 four stroke powered model.

What has been the experience of others with the 65" span TF P51 as regards servos?

Sounds OK.. We over servo and over power aircraft nowadays because we can. Accept that the designer may have had basic competence.

Hi Peter,

I have the TF P40 and that too has the S148 servos and a 120 FS motor shown on the plans. The kit design is quite old, my plans were drawn in 1993, and the 148 servo was a common choice back in the day if memory serve me right. I went for the 2 stroke option.

The kit builds fine and quickly.

Regards

Robert

I'd build it as per plan then, with the control surface deflected (using either the transmitter or a servo tester), push back on the surface with your hand, stopping when the servo moves or when you feel you're about to break something.

Of course, if your builder's intuition lets you down and you do break something, at least you know the servo is okay devil

148's will be fine. I used them on my 72'' 155 powered P40 and had no bother.

Just dont open the throttle in a dive. 120 is well OTT for that model and you may flutter the tail off.
