Notes, Notices, and Tips
SATELLITE ELEVATOR TISSUE Tip-
If you want to shrink the tissue on the Satellite elevator after applying the tissue wet one side and pin it down then, after it dries, wet the other side and pin it down. (See photo)
AMA NUMBERS Tip-
If you would like your AMA number printed on the upper wing of any of the NON-SCALE or SIMPLIFIED models ordered with pre-printed skins please, place your number in the Comments line when you place your order.
BOSTILLATION Errata -
If you are not building with C/A or a quick-drying, super tacky white glue use the third alignment tool at the bottom of the fuselage to hold the center of the fuselage in alignment while your glue dries.
ALL MODELS WITH DETACHABLE WINGS Tip - Trimming
If the upper wing is detachable, you can make fine adjustments to the balance between power and glide, if needed, by shimming the leading edge of the upper wing to raise the incidence. Try 1/32" increments and you can go as much as 3/32". ON BIPLANES - DO NOT lower the incidence of the upper wing by shimming the trailing edge or change the incidence of the lower wing. Nasty stalls will result.
DOUBLE TROUBLE PRE-PRINTED WING SKINS
There seems to have been some confusion about where the pre-printed wing skins go. The un-printed white tissue supplied in the kit is meant for the bottom of the upper wing and the top of the lower wing. The lower wing sunburst pattern is for the bottom of the lower wing.
Some kits with he white thrust button may have prop shafts made with mislabeled wire. The prop shaft is slightly too large to go through the thrust button. If you have one of these kits, please, email me at email@example.com and I will send you a replacement prop shaft. - Howard
DOUBLE TROUBLE PLANS
Some Double Trouble plans were printed without showing the 1/16" square reinforcements on the inside of the cabane struts. These plans also do not mention them in the instructions on the plan. If you have one of these follow the instructions in the instruction booklet. The plans in stock are being reprinted.
