Not uncommon to need a bunch of down trim on this ARF. They don't always get the incidence of the stab correct, it's not usually related to the CoG. Doesn't matter, they typically fly without trim...

Blackbox, The recommended CG is 145mm. I like mine at around 155mm back. I do have a large fuel tank, and usually land with fuel on board. I'd say 150mm would be a good point to start at.

From what I've seen of both the TBM is a totally different plane. Nothing from the TopRC manual would apply. You can download a TopRC manual and look, but I don't think you'll gain much from the...

The stock horns worked fine for me, put them on the way shown in the second photo. That gives good leverage to the servo when the flaps are pulled down. That's the position that needs the most...

I just used the stock firewall alignment for down thrust. On both Zeros it has been good, no noticeable trim difference between throttle settings.

I started out at 155 back, but added some additional weight. It could just have been from an inaccurate measure of the CG. In any case, I'd be careful about going too far back to get more elevator...

Yep, those are what you got way back when the first introduced the TopRC Zero. No scissor linkage. Looks like they found some cheap version to put into the newer retract set. I'd go with Robart...

I finally got the maiden flight done on the Zero. I had to add a bit more weight to the nose, but other than that there weren't any issues. The EME-70 with a 23X10 Xoar pulls it around great and...

Most likely there is a bit of incidence into the stab that causes the need for trim. You should not change the engine thrust unless you notice a difference in trim at different throttle settings....

That's the old style, similar to what is provided on many Jets. It's not an issue if you have electric power or a smooth twin. I wouldn't do it will a gas engine that vibrates much, I don't think...

It's not easy to remove the stock graphics. If you look back, you'll see that I did. For some reason I didn't post the procedure. First it is best to get some of the clear coat off. I used a fine...

LtMash, I wouldn't worry about the down trim as long as it flies well. If it does not change trim as you vary speed you're in good shape. There are quite a few things that can cause the issue. One...

That's the answer then. My 70cc twin weighs 2155g (4.75 lbs). From what you say your engine weighs about 3 lbs more.
