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.
The locations of the CG is indicated on the plan in an unconventional location, at the upper right corner of the plan, off the wing tip. It is about 9/10 inch aft of the spar. The plan has been revised to indicate the CG in a more conventional location, under the side view of the fuselage.
The plans in stock have been reprinted.
SKINNY BOMBER STRIP STOCK - Note
Included in the Skinny Bomber kit are an 18 inch piece of 3/32" square and two 12 inch pieces. The 18 inch piece is the leading edge of the wing. The two 12 inch pieces give you enough stock to make the spar. Since the spar has overlaps at the outer dihedral joints an 18 inch piece wouldn't be quite enough wood.
There are an 18" piece of 1/16" square and a 12 inch piece of 1/16" square in the kit. Again, this is because an 18 inch isn't quite enough wood to build the kit.
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 or the trailing edge to lower 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 to less than the incidence of the lower wing or change the incidence of the lower wing. Nasty stalls will result. The Beanberg D1 has negative stagger and is the exception to this. Its upper wing always has less incidence than the lower wing.
DOUBLE TROUBLE PRE-PRINTED WING SKINS - Note -
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.
GENERAL NOTE -
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 howard@hjlmodels.com and I will send you a replacement prop shaft. - Howard
DOUBLE TROUBLE PLANS - Errata-
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 location of the CG was left off the plans. It is at the spar on the upper wing. The plan has been revised to show the CG. The plans in stock have been reprinted.
Irish Jumping Bean - Errata-
The approximate CG location was not shown on the plan. It is about an inch behind the spar. The plan has been revised.
