RE: ACE RC 4-120 BIPE KIT BUILD
Hey Cherry, I looked at the ACE website and I guess your bipe is a classic. I do not see it offered anymore. I am dyin to get m,y hands on a largish bipe kit. I would love to build the 33% Waco from AMR but it is around $1800 for the kit. My wife would lose it, and me if I spent that kinda money without taking her to the islands first. And unfortunatly for me I cant do both.
So, if you know where I can get my hands on another of those kits please let me know. And keep the pics coming brother. It looks good so far.

RE: ACE RC 4-120 BIPE KIT BUILD
Hi Guys,Got the 1st half of bottom about done,Trying something new on this build.The assembly manual wants you to spray adhesive on wax paper,then stick spars and sheeting down, no pin holes,works really good as long as you have lots of lead to hold flat.
Glue in ribs and top spars,was missing 2 small top spars 1/8x3/16 cut some out of pine,fit good,now I can finsh sheeting.These wings build fast,still have alot to do on them,wing tips,servo mounts,lots of sanding.This is going to be a cool old bipe!!!Well the last wing half is dry fit now,time to glue.More pics.

RE: ACE RC 4-120 BIPE KIT BUILD
Hey Guys,This stuff took some xtra time.Wing tips are done,wing tips are 1/8" ply, after gussets I put a 1/4" band of balsa around edge top and bottom.Did them thing on my Sig Hog bipe,makes the tips a little thicker,easer to cover to.Boxed in new servo bays,cut some 1/8" ply servo covers got them all fit,put 1/4"sq hardwood around bay to screw covers to.A little more custom work to do then back to the manual.Bottom wing has more diehedral than the top,so some N struts will be fun to fab.Well back to work.

RE: ACE RC 4-120 BIPE KIT BUILD
I have a bipe on my watch list on ebay. It probably will go over my limit be a guy can hope cant he?
So Cherry, I have done alot of soldering over the years. To solder cabane wiring you will need a very hot iron. I recently bought a mini propane torch from Lowes. I used it to heat a nose gear wire so I could bend it. It gets plenty hot. And fast. An electric iron will work but I liked the propane torch alot better. Instant heat exactly where I need it. You also need to use silver solder. It can still have a percentage of lead, but the less lead the better. It obviously costs more but it is worth it.
