I'm weighing 923 EW after adding 15lbs to the tail. I'm at 12.02 cg and my tailwheel weight is 71lbs. Flys pretty good at this CG. Just wondering what CG others are flying at....

Model 5 with some 7 upgrades. EW is 798. CG is 12.14. Tail weighed 73 pounds.
I am guessing that the 15 pounds you added to the tail is because of the airmaster prop?

807lbs and 56 tail weight.
9.32 CG w/75" Airmaster
Your cg is close to what my cg was before adding the weight. Do you have problems doing 3 point landings? That's the reason I added weight.

No problem. I can touch the tail first. Not just 3 point. Put gaffers tape or elevator seals on your tail too.
I could tell a difference when I installed the Airmaster. Have since gone with an EarthX battery and have slowly forgotten how it used to fly.
I need to try the gap seals but haven't done that yet. I am an 90hour tailwheel pilot so I still have a lot to learn. thanks

Harlan , have you installed the trim assist kit? that helps a bunch too. On my Series 5 (with a heavy Continental IO-240 up front, 250 lbs worth)and which has the smaller elevator than you guys with the newer airplanes , I had to do a few things to make full stall landings doable. As much weight aft (to me its a sin to carry deadweight for the sake of balance) so 16 Lb Odyssey & ELT in empennage, gap seals and the trim assist kit. I have full elevator authority and can 3 point at any flap setting. Bruce N199CL
Harlan,
How did you add the weight to your tail? Doing it over again, would you have gone with the Odyssey battery?
I was planning to use the EarthX also to save weight but have a feeling I'll be in the same position needing to add extra tail weight. I chose a ground adjustable prop over Airmaster which is lighter but I am thinkiing of going with a Dynon panel and the Fastrak mounting system which will put most of my avionics behind my panel (forward of CG) as opposed to in tail and behind seat pan.
Thanks Bruce, I do have trim assist. I used the lighter battery because its more powerful and I thought weight on the tail would be much less weight than on a battery forward a few feet. What do you use for gap seals and what is your tail weight on your plane. I'm not fond of dead weight but I was told I'd need some when I went with the 915 and the they were right. Thanks
