Over the past 4 months, many have posted asking "Is this engine
a good match to this xxx-xxx model?"

Some don't do their homework (read this thread), some don't understand
this engine's incredible power. Others are just new to gassers.

So maybe a very rough guideline of sorts might help some in deciding
if this DLE20cc gas engine is -or- is not a good match for their model.

This DLE20cc gas engine, is a drop in replacement for most any model
aircraft requiring a glow engine of .90 -to- 1.20 size.

So, if the specs on your model states .90 -to- 1.20, then this DLE20c
is very likely a good match!

If your model states ONLY .90, then maybe. Things like wing area, wing
loading, assembled weight, and so on will determine if it's a good match.

If your model's specs state anything less than a .90 size engine, then
most like it's NOT a good match! There are a few exceptions.

Overall, roughly speaking; this DLE20cc will be good for many model
aircraft requiring a glow engine of a range of between .90 -to- 1.20 size,
and weighing between 7 lbs -to- around abouts 20 lbs.

For 3D'ing; 7-9 lbs but the closer you get to 9 lbs, the slower pull-outs
from a hover, will be.

General sport flying; 9-13 lbs (roughly speaking), and still be spirited.

Scale flying; 10-20 lbs, but as you exceed 14 lbs it may be a bit sluggish.
A long take-off may be needed, a large wing span WILL be helpfull!

In ALL cases, reinforcing the firewall for the stresses of a gas engine
is a very wise move!!!

One other issue to consider in matching this DLE20cc gas engine to your
model will be prop -to- ground clearance. The sweet spot of engine
torque/thrust for this engine is with a 17" prop. Yes, DLE states the
prop range as 14x10 - 17x6, but the 17" props are right in it's power band.

That brings up issues of ground clearance on some potential selections of
models. Some warbirds (and other models) may have issues of prop -to- ground
clearance. If your chosen model states .90 -to- 1.20 then you should be OK.

If you can stuff this DLE20cc into your model, but have ground clearance
issues, then a 3 or 4 bladed prop may be required, or go with a smaller
prop.

This DLE20cc gas engine has more power than a CRRC Pro 26 or a Saito 1.25
(Saito FG-20/gasser) and is a drop in replacement for most any model
aircraft requiring a glow engine of .90 -to- 1.20 size.

Proceed accordingly!
