Southeast RC Engines DLE-30

1.20-1.50 class airframes have most commonly been powered by finiky, fuel-hungry, messy glow engines. Glow engines work very well, but for those of us who prefer gasoline engines there is a new option on the market; the DLE-30 from SouthEast RC Engines. The DLE-30 opens up a whole class of 1.20-1.50 sized airframes to the benefits of gasoline power.

Introduction

Highslide JS


1.20-1.50 class airframes have most commonly been powered by finiky, fuel-hungry, messy glow engines. Glow engines work very well, but for those of us who prefer gasoline engines there is a new option on the market; the DLE-30 from SouthEast RC Engines. The DLE-30 opens up a whole class of 1.20-1.50 sized airframes to the benefits of gasoline power.


Out of the Box:

The DLE-30 arrived well packaged in a compact box. Included with the engine was an electronic ignition, a side-mount exhaust, and a nice set of aluminum stand-offs. I was especially impressed by the fit and finish of the engine. Everything appeared very clean and well assembled.

Product Specifications

Auto Advancing Electronic Ignition Performance: 3.7hp @ 8500rpm Idle: 1600rpm Thrust: 8.5kg @ 100mtr / 7.5kg @ 1800mtr (Above sea level) Suggested prop: 18x8, 18x10, 19x8, 20x8 Spark Plug: NGK CM6 Bore/Stroke: 36 x 30mm Compression: 7.6:1 Weight: Engine - 910g Exhaust - 60g Ignition - 120g

In the Air

I mounted the DLE-30 in a TBM Pilatus PC-21. The PC-21 is a sleek looking 1.20-sized airframe that was expected to come in around 15lbs. The DLE-30 seemed to be a perfect choice. The included stand-offs made mounting the engine very simple, even with the need to fabricate an extension to get the compact DLE-30 into the appropriate position on the narrow nose of the PC-21. At the field, I was surprised to see how quickly the DLE-30 had drawn fuel from the tank. The engine had been sitting in its box for at least a month before I attempted to start it. With the throttle at idle and the choke closed, the engine gave a typical "pop" after less than a dozen flips. Choke off and crack the throttle a couple of clicks; the DLE-30 jumped to life after just 3 more flips. It quickly settled into a nice idle right around 1800 rpm. After a little tuning, the 18x8 prop was turning just over 8000rpm before it was even broken in. Needless to say, I was impressed.

Conclusion

The DLE-30 is a great option for 1.20-1.50 sized glow engines. While it does take some time to break-in and may need some tuning during the break-in process, the benefits of a gas engine in this size outweigh the drawbacks. It's easy to install, easy to start once the break-in process is complete and provides great performance for it's size. SouthEast RC Engines has been great to deal with and will provide any service the DLE-30 may need.

Re: Southeast RC Engines DLE-30

Every gas motor you get will need to have tuning done to it. Simply because of different elevations affecting the carb settings. But I have found on my DLE-30 that I start off with the lowend needle at one turn out, the highend needle at 2 out. Now I use synthetic from the start at 50:1. It may take a little longer for it to break-in. But I run a tank on the ground and get the needles set for a good transition and reliable idle. I then fly the thing! No need to run any gas motor excesively on the ground. Get the needles set and go!

19.4lb of Static thrust on the ground.. BAD thing.. It's WAYY too much for the Velox.. LOL.. Wayy to fast.. Hover just a touch over idle!! punch out is CRAzy..

wow...
using stock muffler?
perhaps you could use a 3-blade then and quiet things up!...
I may have to use this engine in my GP p-6e Hawk instead of a zdz40 and place a 3-blade
iff it can swing it...??

What brand oil are you using for break-in?

Re: Southeast RC Engines DLE-30

Hi,
Just fitted a DLE 30 to the new Hangar 9 Fantana 125. Awesome power, Using 18X8 just to keep speed down a bit. Prop hangs at about one 25% throttle, vertical pullout mind blowing.

Amen to that, running cheap oil thru a new motor seems like a complete waste of time to me synthetics have been around for so long now I can't believe the old wise tail is still around. My banshee is on it's 5th hard season of duneing and it still rips Amsoil dominator from assembly is the way i roll.
