HOPPER TANK LOCATION (Ducted Fan Use)
All BVM sport jets can have the 2 oz. hopper tank located on the right side of the fuselage just below and forward of the Viojett shroud. Be sure the clunk is aft in the tank. Glue tank in place on a 1" balsa block with silicon glue. We have had very reliable performance with this set up and it is not in the way when handling the cockpit hatch.


SPORT JETS CARBON SPAR GLUE JOINTS
Check to see that you filled the gap in the #1 rib where the carbon fiber spars exit. Use a filled epoxy glue. BVM's AeroPoxy works great for this and many other high stress joints.


RETRACTS ALUMINUM ACTUATING ARM
Should you need to replace these parts, they come with the shaft installed and thus are specific. Be sure to order left or right main or nose unit. BVM Part #5260 - $15.00/ea.


DURO-STRUT COLLARS
This handy accessory for the Sabre and Sport Jet main struts eases the rigging of the strut doors and wheel brake air lines. The instructions are explicit about not overtightening the small set screw that holds it in place. To further help prevent damage to the strut outer tube, place a small scrap of rubber or nylon in the hole then apply the set screw. The set screw is only to hold the collar in position. Add a drop of Zap-A-Gap to securely retain it after all adjustments are made.


2nd HAND KITS - You Need To Know
Sometimes you can get a really good deal on a kit that's been sitting around unfinished because the modeler got too busy, etc. If you have been building BVM jets, you have a pretty good idea what should be in the box - all the parts, accessories, etc. If this "good deal" is going to be your first BVM kit, you might need some help to be sure it's all there.

If you do make the deal, be sure to treat yourself to a new set of plans and instructions. All fifteen of our current kits are on the CAD system and the plans are updated often. Average price for a set is $25.00.


GROUND CONTROL
If you have a BVM Sabre, T-33 or F-80 we want you to know that ground handling of these close coupled main gear scale models is greatly improved with new "Duro-Struts." (See details in NEW PRODUCTS section.) Be sure you have the crosswind handling kit installed and use the BVM Jet Wheels and Brakes. You'll have all of the latest products to truly give you "great ground control."


VIOJETT SHROUD & STATORS
REINFORCE WITH AEROPOXY

We introduced AeroPoxy to you in Inlet #25. Without exception, every modeler who purchased and is using this great product loves it and has ordered more. You can put the nozzles in the freezer or flush them through with thinner. This aerospace grade, slow cure glue is great for installing high stress components into the fiberglass fuses and for reinforcing the stator system in the Viojett fan assembly. First, trickle Zap CA into stator-to-shroud and stator-to-aluminum mount joints, then apply AeroPoxy to joints. Make a small fillet with your finger; it improves strength and air flow in the corners.


THROTTLE LINKAGES (Ducted Fan Use)
Change Every 50 Flights

The throttle connect ball is nickel plated (for last two years of engine production) so it is tough to wear out. However, it is a good idea to replace the nylon socket, 2-56 steel threaded coupler and the .055" wire control rod about every 50 flights to prevent a possible in-flight failure from fatigue. Use Sullivan spring ball socket coupler.


FUEL FILTERS (Ducted Fan Use)
You Gotta Use Them - But!...

They must be back flushed often to prevent a clogged condition from burning down your engine. The absolute best filter we have used is the Sullivan #187 "Crap Trap" (large size). BVM now stocks this quality product. Ask for BVM Part #2131 - $3.50.


ENGINE REPAIR
This can be an expensive learning curve in your shop as there is a lot to know. BVM will sell you the parts if you wish, just expect to eat up good parts while you learn what not to do, i.e., change a rod, crank pin must be polished and checked for wear, roundness within .0004", taper less than .0001", no scratches, etc.


SPORT JETS WING ALIGNMENT PIN
Should you have a rough landing, check this carbon fiber pin. It is designed to shear if it is severely stressed. Change it before further flights if it is broken.
