[NSRCA-discussion] Motor Mount Bonding

[David Flynt]

I agree.  Competition brings better products to market at lower prices.

I won't say which mount I prefer.  I'm just glad there is competition.

On that note, I sure would like to see more US made pattern kits that can
compete with the superior quality of ZNline.  I think this task must be a
labor of love and not one of big profits.

I don't know if you've noticed but the one huge positive out of Jerry's
mounts is that the Hyde mount is now 1/2 the price it originally was... I
still say go with the Budd mount!!

While I have not personally tried a Budd Mount, I will now. This is new to
me. I have never heard of Chevrolet attacking Ford for having a recall. They
both make cars. And besides I can save some money on top of it all. Thanks
Merle for helping me make up my mind.

Merle Hyde asked me to post this on the discussion page for him.


 Subj:  Soft Mount Bonding

 "OH" really - so the adhesive is the final solution!!!!  If the rubber
won't tear or fail first the bond is not sufficient.  I have tested the
latest offering and it can also be pulled apart - peels off like a tougher
"lemon"!!!!   Modelers really "NEED" a mount in a 2-20 thousand dollar
aircraft that can and probably will fail!!!!

 Approximately 40 rubber fabricators have been contacted to mass produce a
reliable rubber bond.  They will prototype for $200,000-$300,000 with no
guarantees.  The genuine Hyde Mount rubber bond is a 4-6 hour direct labor
process - with a proven life of over 7000 flights.   Upon disassembly of
high time genuine Hyde Mounts it appears the bond would likely remain
reliable for 14,000 flights or equal to the expected rubber life!!!!

 Hyde Mounts are so reliable that even the severe cantilever force loads
imposed upon the rubber bonding of NO NOSE RING required Hyde Mounts have
been proven to endure thousands of flights without pull apart or failure.

 Some have experienced problems and beam breakage with undrilled nylon
composite beam Hyde Mounts offered several years ago.   Modelers often did
not drill or install blinds nuts per suggestions provided.  Hyde Mount nylon
beams when properly drilled are designed to break at around 100 lbs. force
load - or at around 50G's for a 2 lb. engine - aircraft snap at around 15-18
Gs.  Hyde Mounts now with pre-drilled beams and blind nuts installed have
only been reported to break when crashed or impacted.  The deliberate 100
lbs. force breakage point often prevents more severe damage to the
engine/crankshaft/firewall/aircraft/mount.

 Salvage your hardware investment:   Reliable rubber bonding service
available for the "do-it-yourself" mount builder or other brands.  Simply
send your preferred hardware parts and rubber to:  Merle Hyde
