Issac, does the plans show the degree of travel for the flying surfaces? i.e how many degrees of "UP and "DOWN" for the elevator. Similar for the ailerons. If there is no mention on the plans what is your best guesstimate.

Hi Isaac
Nice work on the cooling ducting for the C54 and esc. Will you be using the Peter Haase light weight heat sink. Is this your first contra. Will you be starting with the recommend 22x20 rear and 22x18 props.
Thanks
David

Hi Isaac
A few more questions if you don't mind. In post 36 you show a link between the two undercarriage legs, aluminium I guess. What is it's purpose. Does it make the undercarriage behave more like a single piece gear set resisting potential folding back of the gear. Would a carbon link be better.
What wheel axles are you using as shown in post 37.
Thanks
David

Yes, I will use the Peter Haase light weight heat sink.

Most of the time, especially in a hard landing one undercarriage leg tach the ground before the other one, The link between the two undercarriage legs, made of aluminum, disperses the forces to the all area of the undercarriage mount.
I think that aluminum will transfer the forces better then carbon because the bolt undercarriage will squeeze the carbon.
I use these wheel axles:
