Default Tested a new Fuselage on the Rex

This morning I flew my T-rex 2 with one of a firends fuselage a HeliArtist Huge 500D after spending 8 hours installing the mechanics in it.

The problem with this design is the short nose needing 95 grams of lead in the nose making the Heli heavier for nothing.
It still flew very nice ,very stable but also the T-Tail is weak to vibration from the rotor wash and it makes the heli shake all over.
I need to damper the fin to solve that problem.
I also need my 25 C battery and thats sad since I only have 2 .
So having to deal with those little problems I remove the mechanics from it and have my second T-Rex back on line original.

Here are some pictures.

looks nice, with the tail vibration do you mean that it catches the rotor wash and just shakes?

Off topic, but what fuse is your blue one and where did you find it?

Wonder if your getting a vibration from somewhere else causing that shake? I have the MD500E army version and I do not get any tail shake at all. When I first installed my mechanics and went for a test flight I had a loud drone and vibration but after I took the mechanics out for adjustments and re installed them the drone/vibration was gone.

I did a test right there on the spot by removing the tail and I had no vibration at all.
So I think by using rubber dampers between the tail rotor and the fin it should fix the problem, but now I already removed the rex from the fuselage .

I think what I will also do is a plate to install the battery sideways as much front as possible to avoid using extra weights in the front canopy.

Default RE: Tested a new Fuselage on the Rex

I havea question I have a T-Rex 450SE with a heliartis bell 222 Fuselage on it, I laned it a little hard and broke all three legs that hold the wheels, I don't have a 7CH radio so i left the wheels out. My question is is it possable to place a normal landing skid on the bottom instead of the flimisy wheels.
Thanks

Shure its possible I had the original T-Rex skids on it before I got the low profile skids.
