HYDE'S  DEPENDABLE  SOFT  MOUNTS

 

2011 F3A WORLD AND NATS CHAMPIONS BOTH USED HYDE MOUNTS

    HYDE Mounts record includes 2 First Place Wins

at the 2011 World Championship

                               1st Place Win For WC CPLR with the YS175CDI
                                      1st Place Electric by Andrew Jeskey  
 
            Over 50% of the Top 10 US NATS Masters Class Flyers and Intermediate
                         Class Winner also used Hyde Soft Mounts for Internal
                                Combustion and Electric Powered Aircraft.

 

Engine Tested: YS170 DZ with APC 18.1 x 11 Propeller

Hyde Mount Tested: LR85 (P/N HCMLR85)

The above Hyde Mount actually reduced vibration 92% @ 7700 RPMs

 

The above testing was conducted by a Major European Luxury Automobile Drive Train Engineer.

 

The above graph clearly shows the above Hyde Mount actually reduced vibration even more than shown in the following descriptive pages under the heading colum "Reduced Vibration/CDR

 

Please contact Merle Hyde for additional information or recommend procedures to confirm or compare the performance of other mounts to a Hyde Mount. Phone: 702-269-7829 or Hydemdh@yahoo.com

 

The Cursor position at 6500 rpm shows vibration is attenuated down from 393 g to ~ 40 g. Thus attenuation is 40.4 / 392= 0.101 or - 10%. Thus engine vibration is reduced by 90% at 6500 rpm.

 

Plot shows total vibration amplitude during run up from idle to full power on both engine side and body side.

 

The difference between the two curves shows how well the engine mount isolates the model from vibration.

 

N.B at low idle (2000 rpm), attenuation is 16/48 = 0.333 or ~  33% at 2000 rpm.

GREAT BUYS!!

STARTING AT

$49.95

Hyde Soft Mounts are great for both sport and competition R/C flying because, unlike other mounts they don't rob your engine of horsepower.  And that's just the beginning.
 
By eliminating damaging vibration, Hyde Mounts extend equipment life considerably and reduce noise.   Hyde Mounts are used by an overwhelming majority of all F3A NATS and World Class competition flyers providing millions of vibration maintenance free flights and have been in the winners circle over 2000 times.
 
Winners of many F3A, Pattern, Giant Scale, TOC, IMAC, and Racing Events have unanimously credited Hyde Mount reliability.
 
Many Hyde Mounts are performing flawlessly with original isolator rubber and bonding even after 5000 flights.  There has been no Hyde Isolator failures or "pull aparts" to date.
 
Please contact: Hydemdh@yahoo.com or 702-269-7829 for specs., dimensions, performance ratings, and etc. for over 600 types and sizes of "tractor" and "pusher" mounts for engines up to 26cu. in/433cc, including electrics.
 
Special Orders accepted for all applications, including UAV/Surveillance aircraft.  Many UAV operators are reporting the best airborne video quality ever obtained by simply using a HYDE SOFT MOUNT.

***What is CDR?
CDR stands for percentage of Current Drain Reduction,  same percentage results are obtained as when vibration forces are measured and compared at the source (motor) and body (airframe) with an accelerometer. For normal control surface activation using batteries/servos, as in a typical model aircraft, the average CDR benefits are:

  • 35% CDR extends flight time per charge considerably- extends major equipment life, including airframe, 4-8 times.

  • 60-70% CDR approximately doubles flight time per charge- extends major equipment life 10-15 times.

  • 80-85% CDR approximately triples flight time per charge and extends major airborne equipment life 20-50 times.

Universal Hyde Mounts CDR ratings are established when tested with popular YS160/175 engines. Performance may vary slightly when used with other 1.2 thru 2.0 cu. in. engines and various airframe construction materials.

The designer of Hyde mounts has over 35 years of vibration affects experience with powered model aircraft. Typical equipment life, including: servos, pots, gears, linkage, and airframe is approximately 25 to 75 flights when hard mounted with a high power to weight ratio engine and aircraft-i.e average equipment life is around 50 flights. Some aircraft and equipment has remained in excellent condition after 3000 flights when using a Hyde Mount-this result is an extension of equipment life by 60 times-try to put a dollar value on this benefit!!!! Also, one specific Hyde Soft Mount remains in excellent condition after 7000 flights (1200 hours) - this mount is now retired and being studied by a vibration engineering department lab. at a major university. The rubber: volume,  dimensions, distribution, tensioning, and bonding, are the success ingredients of a Hyde Mount.

Hyde Mounts are the overwhelming choice of pattern pilots all over the world.  Why?  Because they reduce noise and help to save wear on expensive servos and receivers, as well as the rest of the aircraft.   Highly recommended by Central Hobbies customers.  Light weight and reliable!  See, "Getting What You Pay For."


Installation notes for Nose Ring Incorporated Hyde Mounts

(see in chart above)

The latest technology in soft mounts from Merle Hyde, is an extremely light mount that incorporates the nose ring (see above) that is supported from the firewall. Building a structure in the sides of the engine compartment to support the nose ring is no longer necessary.

Not only does this save weight, it makes a much cleaner and simpler installation of the engine.

Also, there is a 5/16" threaded removable stud that protrudes from the back of the mount for temporary mount attachment.  This feature makes it much easier to align the mount during the initial installation to the firewall.

Simply attach your engine to the mount, and drill a hole in the firewall large enough to allow some movement of the threaded stud approximately where the mount will be located.  With the screw  loosened up enough to allow movement, shift the assembly around until the engine is aligned with the nose, and reaching in from the backside of the firewall, tighten the screw when the mount is in the desired position.

Remove the engine and drill the holes in the firewall exactly where they should be.

It couldn't be any easier.


Firm Idle Mark III Series mounts includes exclusive Hyde Safety Features which prevent pull-apart failure very common with other brands. Built to perform where others fail, the Firm Idle Series offer excellent idle properties and reliable rubber bonding. 

HYDE'S "FIRM IDLE" MOUNTS provide better protection than competing "soft" mounts.  The Mark III series mounts reduce dangerous vibration approx. 35%.

All Hyde Mounts are rigorously tested against other brands of "soft" engine mounts.  In test after test, other brands fail in several respects.  First, they fail to adequately protect RC aircraft from dangerous engine vibration at high rpm speeds.  Out of 14 other brands tested, vibration reduction only reaches from 0% to 15%.  This means that some mounts are not offering any protection at all, and the best competitor's brands are only reducing vibration by 15%.  Even worse, some other brands actually pull apart in mid-flight, destroying valuable aircraft.

ASK THE PROS

2005 World & NATS Champs chose Hyde Mounts (for both Electric & Glow applications).


All other Hyde Mounts reduce damaging high RPM vibration from 60 to 90%.

HYDE MOUNTS ARE PROVEN BETTER

 

Now there's no reason not to use the VERY BEST MOUNT available!  The FIRM IDLE MKIIl series from Merle Hyde are a perfect fit for most sport planes, offer excellent vibration protection, and are priced to fit every sport flyer's budget.
