What would be the proper throttle servo to use for a DLE 20? Also, when mounting in a Sr Telemaster, how is the best way to mount the engine-directly to the firewall, or do I need a special mount of some sort?

Mounting a DLE20 requires using a suitable sized beam type engine mount just like the one you would use to mount a glow engine, which is mounted directly to the firewall. Any standard size servo can be used for the throttle.

I use a regular servo and this motor mount

What no arguments for using a metal geared servo with this gasser, or is it too small or too smooth to need a metal geared throttle servo?

Really just pushing some buttons here, I use regular servos for my small gassers also.

Happy Hobbydays to all, and to all a good flight.

I've been using Hitech HS-225MG for my throttle servos on my three DLE 20s.

Hyperion DS16FCD for mine....

Thats a 5Kg mini servo with carbonite gears

I don't understand the problem. Just because it's gas, you shouldn't need a bigger servo. Unless there is binding in your linkage, you just need enough torque to move the spring. I'm sure 3D flyers want a fast servo, but for a Telemaster any standard, or even mini will work on the throttle. I have a DLE 30 on a 1/4 scale SBack, and use a standard servo, not metal gears. It's worked for years.

Roy, you understand you're addressing a post from 2011?

Proper size beam mount will suffice.
Standard servo is good.

Personally, I always use the " KISS " method. Being Polish, this is not very hard for me to do. Hahahaaaa

Hangar 9 has a nice mount. I have one myself, but have yet to install it in any of my models. It is already drilled and should fit a DLE-20 perfectly.

Read the following:

Enter the Hangar 9 Ultra Engine Mount. The Ultra Engine Mount can be used with a wide variety of engine sizes; from .58 2-strokes all the way up to big 1.50 four-strokes. With this mounting system, there is no drilling and tapping necessary. Twin, slotted-aluminum beams hold the engine in place, but allow adjustment of the fore/aft position of the engine simply by loosening the mounting bolts.

It's my guess that he was in hybernation and just woke up....

True, but I didn't see it until 2014 and wanted to make a comment.
Besides there will always be people new to Gas and want to hear different opinions

How the heck did this happen ? Did not notice it myself, until you brought it to attention.

Mannnnnnnnnnnnnnnnnnnnn, talk about loosing it, when you age !!! Hahahaaaaaaaaaaaaaaaa
