Torqmaster... have you replaced the stock tailwheel? It's quite heavy and can save you several oz in the nose...

Also yes... put the battery in the nose. MANY manufactureres are now doing this as the new ignitions are shielded and quite clean.

Obviously a thorough range test should be performed with any new aircraft... and if you are using a PCM receiver... swap it for a PPM for the range test.



Dirtypool... 6/32 horns are not enough for this plane. If a person wanted the lightest system, I'd look at Chip Hyde's aluminum ball bearing horns... they come with special clevises that fit the ball bearings and there is no slop. The mounting plates on the BME surfaces are perfect for these horns.

They are VERY lightweight... 4 of them in the tail only weigh 19 grams (.67 oz)... and that's including the clevises. The Dubro HD horns (2 elevator & one pull-pull) weigh 67 grams (2.36 oz).

With them you'd save 1.75 oz in the tail and a whole slewful in the nose... maybe 6-8oz...

You can get them from Central Hobbies... http://www.centralhobbies.com/contro...s/chmch-1.html


When I first used these on my Double Vision (they came stock with it) I was a little leary... installation is like this:

1) Determine where the horn will sit and drill pilot holes for the screws
2) Cut the covering out in a triangle with the pilot holes being the points
3) Place a drop of thick CA on the bare wood
4) Install the servo horn with 3 supplied screws (they are short... but long enough to go through the mounting plate


I have subjected my DV to some VERY rad maneuvers... not a hint of these horns failing or coming loose.
