weight is penalized by the engine of course.
AUW is 61 ounces
finish on fuse is yellow Jap tissue doped with nitrate and fuel proofed with Klass Kote Clear with a dash of yellow added to give more depth.
the firewall is actually 3/8″ in front of the LE…but the forward pylon post is swept back to look more like the ’70 series Satellite 1000 which is why it looks like the nose was extended more than 2″. the FW is 2″ behind the LE on the stock 1300.07/17/2012 at 1:28 pm #44791GeneChristensenParticipant
Where is your BP at from the TE?

will have to measure it.
we always calculated CG in percentage measured from the LE…which is 62% on this one.07/19/2012 at 3:27 pm #44793AnonymousInactive
Does that not mean that the BP is 38% from the trailing edge…07/19/2012 at 5:55 pm #44794AnonymousInactive

depends on which side way the wind blows too……….07/19/2012 at 7:14 pm #44795Dean McGinnesParticipant
I am guessing from the CG location, and the “smallish” stab, that you are using a (shudder!) VIT and Autorudder.07/21/2012 at 3:22 am #44796AnonymousInactive
on this one i am Dean.
the next build is a 70 series 1000, will be classic gas.07/21/2012 at 1:48 pm #44797Dean McGinnesParticipant
Keep me posted on the 1000. I am considering one also in the Fall.07/21/2012 at 3:10 pm #44798Rudy KluiberParticipant
Reading back thru this thread, I see you used a RR Rossi 65. I have that engine also.
What sort of engine mount did you use ?? I’m looking for something solid

I used a C.B Associates Inc. mount.(CB 60R #5308 long mount) I think MECOA carries them now.
Here is there web address… http://www.mecoa.com/
Get on there site and look for the white “CB Associates” advertisement link on the lower right side of there home page and go from there.
It would probably be advisable to call them direct…they don’t seem to answer emails. 😯 😯 😯 😯
Here is a little more info to help cut to the chase…..
MECOA K&B Manufacturing
PO Box 5

the OPS 65 uses the same mount as your Rossi 65. holes are the same too………what sucks is that Randy is not planning to make the CB mounts at all. even pleading and offering big bucks did little to get his attention. probably too many logs in the fire and the fact that they are currently moving.
i have now got 2 of the CB mounts, but one was luck of the draw that someone in Canada saw my wanted post and sent it to me. the other was given to me, but has a telltale sign of being in a crash. wasn’t obvious until i had it mounted and saw what looked like upthrust because the beams are bent. perhaps useless. i certainly won’t attempt to use it.
i do have an acquaintence in my complex that is a machinist looking for work……he’d be willing to turn a few if the the price is fair and enough wanted.07/22/2012 at 11:13 pm #44801
Thanks Mike for the CB mount update.
I’d be willing to purchase 5 each of the mounts if the price is right.07/23/2012 at 6:23 pm #44802RONALD BENNETTParticipant
Find a friend with a mill and have them mill the mount arms true to the back. Then all you would have to do is raise the mount to the thrust line when you mount it.

I have been following this thread from the beginning. I built my first 1300 about 1985. I ordered the plans form NFFS and wood from a balsa supplier, mistake number one, I did not specify contest balsa. Some of the wood, I believe was rejected by Guillolw’s for being to heavy! I ordered an OS 61 from Indi RC to power the monster. The airplane was built per Hunter instructions, CG at 83% Right thrust and down thrust. First flight was short, shallow climb, about 50 degrees, engine shut down; nose dropped and made absolutely no attempt to recover with major damage to the wing. After the wing was repaired and a second attempt was made. This time it stalled in the glide and destroyed the wing on landing. I guess I am a slow learner but I finally got the clue that it was tail heavy. I added a 2-inch block to the nose, between the firewall and a new firewall. His helped somewhat but not much. All this time there was no damage to the fuselage or the stab at all. Next, I built a new fuselage, adding 4 inches to the nose and a smaller stab, about 34% of the wing area. I covered the wing with Polyspan and the stab with Ultracote, and moved the CG forward to 65%. Polyspan is nice stuff but do not use to much dope. I sprayed 5 or 6 coats of clear over yellow florescent yellow dye from MRL. The color is great but over time all that dope warped washout in the right wing, and that is really bad! I would take the warp out, it would be back within a day or two, and then I notices that the Polyspan was buckling and crushing the ribs. In disgust I ripped the Polyspan off, repaired the wing and recovered it with Ultracote now, it flies fine. Two years ago, at the Nat’s, Alan Abriss mounted his camera on the 1300 and the video that was taken is on his 2010 Nat’s DVD. The airplane is not difficult to build; there is just a lot of it to build. The airplane is so large it is very prone to damage on landing. Flying the monster is like a Religious Experience and it starts the minute you chuck the engine in the starter. The OS turning that 12 X 4 APC at about 17 or 18,000 while you are fighting the wind trying to get it pointed the right way, you are more than happy to get rid of the beast before it eats you.07/24/2012 at 12:24 am #44804
Sounds like fun…BIG models like the 1300 make people scatter or at least watch you when you launch.
What a heavenly experience….”I need a Timer Please” this is an official flight. 😀 😀 😀
I had Randy Archer tell me once that the model looks proportional to me…I snickered.
