Introducing the "Magic Motor Mount" !
Every once in a while something comes along that just makes building and improving on what we thought we had figured out that much better. Well, that's what I think of the new "Magic Motor Mount"!
Made of strong nylon, 3" long, and weighing in at only 5.7 grams, this motor mount is a foamy builders dream come true. Quite simple and brilliant in design, it makes the installation of your 8mm tube brushless CD rom or x-mount motor a breeze! Mount the x-mount to the disc and slide it in or insert the tube of your motor directly in. Everything is held in place with the clamp screw and is EASILY removable! NICE...
In the case of the "Bug", we only need 1 1/2 inches (2.3 grams without the x-mount disc) of the tube, as we do not really need the whole 3" length. You may choose another length for other models.
It can be glued directly into the plane. It's a great optional mount for ANY foamy! Available from lightflite.com for $5.99 NEW LOWER PRICE!
Here is how it is used in the V3 BUG which is precut to accomodate the mount...the mount is CUT DOWN to 1 1/2" with a hobby saw or hack saw. Now it will weigh in at only 2.3 grams! Score all 4 sides with the same saw, for better adhesion to the foam and glue.
The mount will ultimately be glued in between the wing and fuselage foam when it is installed as shown. But, before you glue it in, make sure the motor shaft fits into the mount quite easily. If you have to file or clean the inner diameter a bit so the motor slides in easily enough, now is the time. A 21/64 drill is perfect. When glued, assuring that it is also glued to the carbon rod underneath the wing will add additional strength and a bit of shock resistance. Just make sure it is level and straight as to not induce any undesired thrust angles. A very neat and secure set up for installing a motor in the Bug!
INSTALLING the Prop Saver
Important! Put the prop saver on the motor shaft and push it on as far as it will go against the motor bell. Forget the flat spot on the shaft, push it further onto the motor shaft and tighten the screws. This will leave more of the shaft exposed to help center the prop as shown below in the pic. Set the prop on the prop saver and install the o-ring. Now the prop can be bent out of the way in a nose down or hard landing as to save damage to the prop and not stress the motor mount attachment or the fuselage.
NOTE: some props may need to have the inner center hole counter sunk just a bit for the prop to sit level on the prop saver. Use a 1/4" drill bit by HAND, and gently clean out the center prop hole by removing a slight amount of material. Your prop should now sit level. If you ordered the "combo kit", you will notice that this has been done for you.
This is how the gear looks installed
The battery is installed on the right front just behind the motor. A piece of velcro is adhered to the fuselage with a little help of the UHU glue. Apply a light coating of UHU to the sticky back of the velcro and put in place. It will adhere very well now to the EPP. Let dry., it will not be removable. The pic shows a short piece of velcro, but use a 5.5-6in. strip of velcro here starting at the motor mount rear end and back to about where the rudder servo on the other side is. Remember, the CG of the BUG is 1/3 of the main wing, not counting the elevons. Pinch the black painted canopy about an inch back from where it starts. (this approximates about 1/3 of the main wing). The BUG should be about level with a slighty nose up attitude. Adjust the battery accordingly.You are good to go. When properly trimmed in the radio, the BUG should fly slow and level at about1/2 throttle.
The ESC speed control will be mounted to the right underside of the wing and the ESC receiver wire will be routed along with the servo wire to the receiver side. It can be attached with the included small black cable ties or again velcro with a bit of UHU on the velcro sticky side. Let dry.
NOTICE: NO servo screws on the TP50 servos! The horns on these particular servos snap on quite snug. Yes, I fly without them! They have NEVER come off in flight, no matter how aggressive I fly. However, they do come off in a mishap like stuffing it in or the like and save the servo from undue stress. I have NEVER stripped my servo gears and have hundreds of flights!
The receiver is mounted opposite the ESC on the under left side. All wires are routed to this location. It can be attached with the included small black cable ties or again velcro with a bit of UHU on the velcro sticky side. Let dry.
Rudder Control Upgrade or Repair
Simply take a small piece of scrap EPP and cut a slice in it to accept the rudder control rod. Glue it in place as shown. It will provide more precise control to a weak joint or simply as an upgrade for additional control.
