I came up with an alternative solution to use a different size servo for the tail on a 450 size heli without mounting it on the boom. Not sure if this idea has ever come up but thought I would share it anyway. I recently fried my tail servo on my 450 and instead of replacing it with the exact same I decided to use one of the many mini servos I have laying around. Many 450s use a mini style servo to operate the tail by mounting it on the boom but my Chaos 450 has a frame mounted type as you can see in the included photos. That said, I had to modify it in order to mount a smaller servo onto it. The pics. should tell the process. The org. servo is on the left, I'll be replacing it with the mini servo on the right. As you can see the difference in size. Here is the tail servo mount that I'll need to modify in order for the mini style servo is able to be installed. This is what I came up with. An old plastic servo mount was used to custom make this piece. It is then inserted into the mount as shown. A perfect fit! "Measure twice, cut once"! Now....a trail fit before drilling holes to add screws. With the screws added, it's ready to be mounted back into the main frame. Here is what it looks like once installed.

That's a great idea. I might do this myself on my SE Align 450. I did not know frame mounted servo version uses a bigger servo. Is this to correct the C of G and use a heavier servo beacause the servo is not on the boom? How is the balance in your heli now after putting in the lighter one. I am interested in doing this but not if it plays with the C of G. My heli is perfectly balanced as is and I don't want to move electrics. I always like to tinker tho!

It did not mess with the CG much as it is so close to the center of the heli anyway so not much was changed. It is working well on my 450, also the plus side is that it'll be a cheaper cost to replace should I do damage..LOL

Make sure the servo is a high enough speed and can handle the torque. The pros are designed around a higher end beefy servo. Though those servos are great for cyclic be careful they can handle the torque of the tail. I had to boom mount the same servo on my pro to fit into the scale MD500 body and I smoked the poor little servo. Great idea as how to get other brand and size servos to fit in the frame!!
It's all our suggestions and tips and tricks that make this hobby that much more enjoyable!

Sure is and thats what makes this hobby great....+1 Yeah, the only reason I came up with this idea was because I didn't have another boom mount and still want the look of the "in the frame" style. It's working well for me so far, until something happens...I may reconsider but so far so good.

Great idea, but there is already a carbon fiber and aluminum plate versions of your idea for a couple bucks each. This is a great homegrown fix. hobby-wing.com/tl2607.html
