do you guys think  a DLE-20 will not be too heavy for this plane?

Too big, too powerfull, too much for such a little bipe.
It's designed for an electric setup, and the DLE20cc gasser might just rip the wings off that bipe!

Go back to the beginning of this msg thread, and read Post #3.
You'll do good with a model that requires a glow in the .90 - 1.20 size range.
That's what the DLE20cc replaces well.

Good match for the plane.

Had fun w/the electric version and the gasser is just as fun only..no waiting for batteries to charge!

cheers,

Insuffecient wing area, wing loading, it's designed for electric power NOT a gas -or- glow eng, and airframe is ONLY 4.1 lbs.
How many bad points do ya need, to know it's a very bad combo?

Sure hope you have good insurance if you do make the mistake of going that route.

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Over the past 10 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 DLE20cc
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!

the electric setup i have on this plane is just 200 grams lighter than a DLE setup I actually weighed all the items require for the dle setup and the items needed for an electic setup.  so if this plane flys well with the elctgric setup then i will convert it to the DLE20 and see how it goes.

Never said I was, but if YOU think so.....thanks!

His bipe is NOT a good candidate for a DLE20. In his case it's like putting an eng 3x the recommended size in it.
Being designed for EP, how long do ya think it's frail firewall might handle the vibrations of a gasser?

My guide is just that, only a guide, not law, not rule. As such it's up to others to determine if they have the wing area to handle this eng, without over loading the wing loading values and creating a barely enjoyable model combo. Consider yourself very lucky.....so far. I'll be curious to see how many .60 models with a DLE20 will still be flyable come next year.

Reading is fundamental, comprehension is an acquired skill!

but can you give me YOUR opinion what is the most enjoyable wing loading or cubic load numbers for a good acrobat plane and a mild 3D plane?

a 60 2s has the same case as a 90 2 stroke... an OS 120ax is just a fat hair bigger...the DLE 20 is a drop for a 120 2 stroke ..... a plane that light and balanced properly should make for some wicked 3d

just dont do any abrupt full throttle maneuvers, like snaps, walls or blenders

Status: offline 		I'd go with a minimum W/A of at least 950sq.in. or higher, and an AUW of around abouts 7-8lbs.
Something suggesting a glow eng size range of .90 - 1.20

I have one at 952 sq.in. w/a & 8 lbs, another at 1224 sq.in. w/a but only 7 lbs.
For 3D models they fly great and are very predictable.

The biggest exception so far has been with various warbirds. Some have mounted this DLE20cc
into .60 sized warbird airframes with good results. Even though their w/a might be low, and wing
loading high, such are designed for a bit of speedy flying so it's doable.

Your bipe at 712 sq. in. w/a would be one handful to control & fly enjoyably.
You'd really need to stay on top of it at all times!

Ever hear experienced flyers say "he's flying behind the model" -or- "he's flying ahead of the model"?
Flying behind the model is what you'd have with a DLE20 on your bipe, always correcting it at every manuever.
Constantly staying on top of it just to keep control. Not my idea of enjoyable flying.

But what do I know. It's your call, I'd just like to see you with some sort of good combo, one you enjoy flying,
NOT one that causes you stress every time you fly it.

Proceed as you please.

Status: offline 		pcfixer,

thanks for all the info. once i get it in the air with the electic setup. i will know how she flys, the other option i had was a 15cc gas engine which i know the power to weight ratio isnt good but its lighter than the DLE 20, so the wing loading will be less.
I have the DLE20 on a TMPro Katana 70 profile 945 sq in and its a joy to fly with amazing 3D flying.
