Ok so the only stupid question is the one don't ask, right!!
How are you securing the elevator, I am guessing glue in the tubes to the righthand stab, but are you securing the left with screws? I ask because of the anhedral I am concerned about the length, depth of these screws?
I think the screws got trashed as i didn't see them, what size are they and how long? I guess 2mm but length?
cheers David

As you mentioned, one side glues in and one side has a screw. There is only 1 hardpoint. I ended up using a long servo mounting screw, one of the socket head types from Micro Fasteners.com. The supplied screw is fine, but I went to the socket head servo screw since it was a bit larger diameter and longer. I did the same on my BiSide.

Next construction question everybody? How tight are you assembling the stab. I have the Washer fitted, thanks BJ and have also added some sticky felt seals on the stabiliser routes. Nothing is final glued yet but the rear left is rubbing against the fin. I can loosen the assembly and all is ok, but how big are your gaps?
Cheers Dave

Mike,
Thought you might like to know I have maiden-ed my Invitation. No issues what so ever. Flying stab was dead on for first flight. Used BJ setup included with the kit. Only needed to make a small change in wing location to remove a small amount of aileron right trim . Working on CG currently. CG is currently set as Shannah had shown. Very close. I used the battery tray included with the kit and located it as shown on BJ's page. Do need a small mix for for down lines. (Throttle to Elevator) Very nice plane! It is very solid in the air! No hunting what so ever. Currently flying with a 21.5X13 Falcon Prop. Heading out tomorrow to dial in CG, Snap condition, and spin condition. Pt rolls and slow rolls are easy with this plane. The flying stab is very smooth. Seems to help in maneuvers needing down elevator. Inverted flight is very easy to maintain.
So far so good!

Remember to set your horizontal flight trim for about 70% throttle and then adjust your throttle to elevator mix accordingly.

Guys I have some new stock due in about 10 days.
I'll have some Invitations and Essences in stock.
It's a limited amount and I can take the orders now. If interested please contact me. The planes are really flying well and are a proven commodity.
Thanks Mike Mueller

This plane is very easy to fly especially the constant speed control...almost no knif edge mix .
With this plane I win first place in Taiwan F-3A championship.
I am very happy with it's performance

Shannah......
Hi Steve....could you please post the length of the servo arms you used on the Essence?
I'm starting a build right now and am getting ready to order parts.

Hi Dave,
I am using stock Futaba arms. On the Elevator and rudder I use the larger "X" style arm and the clevis is mounted on the outer hole. I think it is about 17mm from center.
On the Aileron I use the large wheel disk horn. The clevis is 20mm from center.

Still have time to bring product to the Nationals. It's a safe way to get a plane and save on the shipping costs.
Thanks, Mike Mueller

Hello gent's
had Maiden on my Essence yesterday ...dont botter to put in any pics as its similar to the others.
My first impression is pretty good, used the jigs for setting stab's and wings the thrust lines is after the fuse front.
Just have 6 flights so fare and the throws are still not at my taste completely , but so fare the plane fits my fingers better than my Arixtra .
I have use futaba SV digitals all around OS belt motor and Jeti Mezon and the Efuel gauge from denmark to have track off the amp on the batteries.
Only thing I didnt like is that the undercarriage is to low at least on my clubfield ( it was a bit high grass) but it was Heavy to get off so I will change this to a other that I have.
I change some off the controll linkage as I dont like z-bends linkage .
Some off the supplied plywood is not good its to soft , the undercarriage plate and support is to soft so I had to re thighten the bolts after some days...it came loose...I soak it With thin CA and will see how its goes, the canopy is fasten by a piano wire ..I may change that to MK Magic boxes after some time.
Weight With 5000mah batteries is nicely 4740gr .
Finish on the planes is wery good not as an Oxai but good enogh for me.

I like the power "curv" (correct Word?) on the OS ..no rpm numbers haven bother to messure but it is about 80 amps on a 21x14 Falcon .
Its to early to conclude that this is the motor for this plane ..only 6 flights on it (the plane) but had the os in my arixtra for ca 50 flights and it was a better match than the 14XS Hacker ...at least in my oppinion

One thing to think about is that on this plane With the OS (that is a bit Heavy compare to others) I have the battery about 7-8 cm from the motor thats made me put the ESC under the battery plate to get CG at the right(recommended) spot, so if you og for a lighter motor you may have to move the rudder servo forward to the canopy opening.
I now have the battery centred (ca) over the UC bulkhead

I just wanted to let everyone know how enthusiastic I am about Snowman44 motor mounts for the BJ Craft series of airplanes.
These mounts are water jet cut from Mil-Spec G10 FR4 .093" material to perfectly fit the Plettenberg Advance motors.
The sizes are 3.7" which fits the Essence and Invitation (G2 series of BJ planes) and smaller right sizes for the BiSide, Nuance and Prolog fuselage shapes.
I'm sure they would fit other airplanes as well.
I have built 3 BJ Craft planes and used the Snowman44 mounts on all of them with great success.
I sent Snowman44 a PM and it arrived quickly for $39.95.
They make a really nice installation using standard epoxy or Hysol 9462 available at McMaster-Carr.

Do the bolts from the motor install from the front then and are countersunk?
