Posted help for a BVM, but some of you are telling me a may be an early yellow aircraft.....changed the ad subjet to yellow, but I have a BVM manual for guidance.... can anyone help? and will the throws in the BVM manual be OK for the yellow aircraft? If not, Im gonna need them too! LOL


manual it says 7-5/8 from the lead down the leading edge. Once you get there, do you go from that distance 90deg to the fuse? or once you get 7 5/8 down the leading edge is that the exact point to lift and check? I have the manual but dont have the wing illustration pic showing it.

Can anyone post pics and help? I would like to maiden this used F-16 on July 4th....

thanks guys!

You lift at the measured point on the leading edge. Also I was digging for my F-16 info that came out years ago and I we used to run the CG around 7-7/8 down the leading edge. Made the flair on landing a bit easier if you drug the bird in under power. The 7-5/8 cg will get you in the air without a problem, but I am guessing you will want to pull it back as you fly it.

Big key to that model is to get the gear up after rotaion. It doesn't like to have it hanging down, too much drag.

this is the older one without doors...gear is halfway in/out. Im sure it helps though..

thanks

BVM F-16's were never made without doors. Scale gear only and full gear doors. Sounds like you have an early Yellow kit. How about a picture so we can verify. I would hate to have you CG it only to find out it is from another manufacturer, and not BVM. There are very simple things to look at to verify. Inside the gear doors, there was a piece of 1/8 balsa molded between the fiberglass layers to ensure stiffnes in the gear door itself. This is probably the easiest to check to see if it is a BVM kit.

How far back should the CG be with full fuel? Such as the case with the EVF and Battery packs where the sullivan tanks used to be.

Pics up! thanks so far guys! maybe it is a early yellow aircraft!!??!!

This is definitely a Yellow F-16A kit. I am sure Chaun Evans will chime in soon, this is his game and he knows them well.

Glad we got clarification, look like a nice bird. Will be good to get eth correct CG and I am sure the first flight will be a great one.

Good luck.

Dblex,

I have to agree with the others here and say this is an old YA F-16A. I have one of these too and I still have a complete manual and the two plan sheets. My manual is stamped "copyright 1989 rev 0." I've scanned in the preflight page for you which speaks to the control throws and CG questions you have. However, it is a .pdf and RCU seems to not allow me to upload .pdf files. PM me your email address and I'll email you the page to you if you wish.

The long and short of it is the manual says:

ailersons 3/4" up 3/4" down
elevator 1 1/8" up 1 1/8" down [preset leading edge 1/8" below scribed line (up elevator)]
rudder 1 1/2" left and right
throttle capable of full off to full on without servo stalling
retracts actuates arm in both directions without binding

Paragraph 5. Check the C.G. This is critical on all airplanes. On the F-16 this is 1 1/2" - 1 3/4" behind the panel line at former B-1 (front former) [this is also the leading edge of the hatch].


This plane was actually made in two different versions at that time, a "sport" and a "scale" version. Mine is the scale version that I've modified to accept the newer scale gear. The throws and CG are the same for boths kits. The first page of the manual says:

"This 1/9th scale model of the F-16A is designed to fulfill two types of requests for models. It is designed to be built as the sport scale version or the scale version. The only difference in the materials used in the construction of either version is the gear doors. On the scale version, the gear doors are molded separately whereas on the sport version they are just panel lines with no recess lipe."

Good luck with your first flight; post an update.

Dblex,

I just thought of another thing. If you haven't flown one of these F-16's before you may not know how to line up the elevator correctly. The trailing edge of the elevator should line up exactly with the trailing edge of the air brakes if the plane was built correctly. When you hold the elevator in this position the leading edge should be about 1/8 of an inch from the bottom of the side of the empennage. There will be a faint scribe line right in front of the leading edge on the fuse at this point to ensure you've lines things up correctly.

But John Redman was right, Shaun Evans is the real expert (according to what everyone says in a millions posts here on RCU) so you may want to contact him if you need pointers.

Hey Tim,

Thanks for coming out and throwing some good info towards Dblex. Good info on the horizontal stab alignment, I have seen what can happen if they aren't. Dblex's model looks very nice and I am sure it is right on, with your help I am betting he hasa great day at the field.

Thats what this site is best for. I've gotten a lot of pointers from this site that have saved me a lot of hassle and problems, I was just glad to help out.

hi ,can yo forward me copy of the f16 yellow manual, hope you can help cheers steve.

Yes this is a Yellow F-16, I have the scale version as too ive lost my manual but if it remember correctly the cg is mesured on the wing shelf, everyone here is righ that sean will chime in soon to give the correct answer.
