RE: Extreme Flight 87" Yak 54 - Build & Fly
Personally I do not like any cowl ring setups
tho they don't show bolts - all the rest of the setup is either awkward or prone to failure OR you can't detect bolts coming out till they FALLout
Easy set?
a 1/4" thick strip on each side of F1- inset 1/4"
1/4" blocks /plates solidly attached to cowl --which match these plate positions
drill thru - add blind nuts and countersink for skt bolt heads
This also self aligns each time cowl is mounted
The ARF guys don't do this -- as it simply is additional work step in construction
Th nice part is instant access to all mounting bolts which are also flush with cowl surface.
the shock isolation technique is in my opinion not as smooth looking and is far more prone to failure over time
Just my own thoughts -------
