As most of you guys have commented this plane is tail heavy with the given CG in the manual, IMO the push rods are too short (make your own), the true-turn spinner does not fit the power 110 (even though the manual says to) and the customer service with horizon sucks. Manual is wrong in many places, covering is yellowing (yes mine too). Now saying all that, its a descent flying plane once shes all tuned in. I think that lighter is the key with this bird and use the SFGs. However its still not a great plane or at least, I haven't gotten mine there yet. Still working on it.
I have mine flying better now but I think the plane is still a little heavy. I have made allot of changes and am now running 225MGs for the elevator and have installed 7775MG low profiles for all other surfaces. The 7775MG give me 125oz/in at 6v an are very fast. They seem to be a descent servo and center really well (any thoughts here). I was running 2x 4s 5000's with a Castle HV85 and CC BEC PRO and could get the plane to balance with this setup not using any additional weight as I have most of the electronics mounted up on the firewall (FYI As master tech has pointed out I find anything much further away from the forward CG a bit tail draggy). But as I said the plane still seemed heavy to me for where I thought it should be.
To further cut weight I installed a ICE 100, went to a Xoar prop - 18x10, Extreme flight spinner, and changed out to the smaller Castle BEC. I wanted to go to a 6s setup but no matter what the Eflight power 110 is a dog without 8s. maybe if I resolve some of the other issue I have I will install a Hacker A50-12L but going to wait on that. Any other recommendations are appreciated as I'm still not super happy with it yet. Also has anyone else who is flying 3d with this plane done Mastertech's checks or performed these changes. Just searching for the golden egg here.
Currently sitting at 9.8 lbs
