RE: What Aircraft are you installing your DLE20
 

I've tried an ES Composites ES26G but cut the header too short and need to get another one. Another member on the site has tried this same pipe with a 7" header (from flange face to end end of header outlet measured at the center line of the tubing) has gained about 650rpm with a Xoar 17x6 (from 8050 to 8700).

The headers that will fit this motor are the Macs Products 2985(std), 2986(long), 2987(ex long) which were originally designed for a YS 91SR.. The 2986 (which is what I've been using) is 10" from the flange to the end of the tubing measured through the center line of the pipe. I need to buy another one and try again, just haven't had time here lately.

Pls advise how to mount the engine and what do you suggest to take care of

Cheers

Hemz

RE: What Aircraft are you installing your DLE20
 

Simple.....

Bolt the mount to the Firewall an bolt the engine to the mount !!! Your engine is mounted....
Care:
Make sure the bolts are tight
The engine is inverted - spark plug pointing down

If still in doubt I will explain on Friday night.....
Cheers

Sir ji

thanks

RE: What Aircraft are you installing your DLE20
 

is that the ESM Adrenaline 120?<div>
</div><div>If yes, I thik you are going to be disappointed. That plane will weigh close to 4.8Kg when you're done building it. It would prefer a 30cc.</div>

RE: What Aircraft are you installing your DLE20
 

How will I mount the 30cc
Could you please guide me
Cheers

RE: What Aircraft are you installing your DLE20
 

But the DLE20 pulls 6Kg+ with the APC 17x6 @ 8800 RPM....Can you please advise why should it be under powered ?

RE: What Aircraft are you installing your DLE20
 

Don't worry about it. I have a DLE 20 with a Vess 17x6 on a 12.5lb PT-17 Stearman. The thing still has great vertical!

RE: What Aircraft are you installing your DLE20
 

Iagree, Ihave a new DLE20 on a Hangar9 Taylorcraft, pushing 16+ pounds with a Vess 17X6. It pulls at about 14.5 pounds of static thrust. It won't go vertical forever, but has a lot of authority.

RE: What Aircraft are you installing your DLE20
 

This looks like a good candidate for a DLE 20. But the specs on weight seem too heavy for 3d.

Nice looking Sukhoi. What's the wingspan and weight?

RE: What Aircraft are you installing your DLE20
 

Seagull just came out with two planes. This is one of them.

RE: What Aircraft are you installing your DLE20
 

Windgap - I see that's a Yak 55, 69". Did you see the spec calling for a 30-35cc gasser? I'd say a DLE 30 would be a much better match than a DLE 20 for that plane. And the 30 is only $50 more. I always prefer better to have MORE power than less. I have a DLE 30 in my 73" Carl Goldberg Sukhoi - that thing is a rocket! Will pull vertical all day. Great engine.

RE: What Aircraft are you installing your DLE20
 

I guess you can tie a rock to a dle XX, with enough power, it'll fly. Unbelievable. Definitely not a 3d bird if it'll require so much engine.

RE: What Aircraft are you installing your DLE20
 

I'm not sure of your point? Even if you were able to keep this plane at it's minimum advertised weight (11.5lbs), it's never going to fly like most would expect a Yak to fly? Most WOULD expect decent 3D performance from a plane like that? I think the old "over powered" airframes are now the norm with these newer lighter gassers.

Still, if you were looking for something aerobatic with somewhat less than unlimited vertical, and only limited hovering, I'll bet the plane would be really fun to fly on a 20cc. Maybe you could even get it under 11.5 pounds?

RE: What Aircraft are you installing your DLE20
 

ahicks - agreed. I'd think if you want 3D in that plane you'd need more than a DLE 20. But you can always try, I suppose...

RE: What Aircraft are you installing your DLE20
 

anything more than 68" WS and 5 Kg in wt. will not 3D with a DLE20. This baby is above the threshold on both accounts and so a 30 it has to be.... See page no. 1 of the DLE20 thread.

I will recommend a DLE30 with an 18x8 or 18x10 for it.

RE: What Aircraft are you installing your DLE20
 

I have modified a Dragon lady (66 inch ?) to take the DLE 20 .

Reduced the Dihedral ( spelling) ,ele and rud have been put up the back
A BEC ignition kill has gone in and the fuel tank was moved colser to the COG .
The canopy is also off a Swallow pattern plane so it has a pretty slick look .

RE: What Aircraft are you installing your DLE20
 

Installed a DLE-20 in a CMPro 120 Cub have 4 flights on it now. just love this motor plenty of power and uses hardly any fuel, if I had to guess I used about 3-4 oz for a 10 min flight and it's still new so maybe a tad rich. I did have to open up the cowl for more air but I don't think it looks bad.

RE: What Aircraft are you installing your DLE20
 

nalby plane looks really good. btw how powerful is the plane. does it do verticals?

RE: What Aircraft are you installing your DLE20
 

Is that the Cub that Nitro Planes sells?

RE: What Aircraft are you installing your DLE20
 

Since the engine is new I really haven't pushed it yet, but I have done some 3/4 throttle loops and it had no problems and the cub is a little heavy with the dubro 6" inflatables and 16 oz of fuel it comes in at about 13lbs 8oz.

Yes it's the same one nitroplanes sells, HobbyKing sells it also. It's a pretty nice arf, the only problems i've had was that the rudder and horizontal stab were really warped, some time with the heat gun and putting turnbuckles on the flying wires straightened that all out. Also the tail wheel was tiny so I used a dubro 957 Semi-Scale Tail Wheel System Size 60-120

RE: What Aircraft are you installing your DLE20
 

What is the wingspan? 120"?

Thanks,
AV8TOR

RE: What Aircraft are you installing your DLE20
 

It has a 91" wingspan so it's somewhere between 1/4 and 1/5 scale.

RE: What Aircraft are you installing your DLE20
 

Well, it looks nice and sounds like you got a good combo together. Thanks for the info.

BTW, interesting setup on your throttle linkage.
