I am not sure that I am in the right forum for this question but I hope someone can help.

I have a World Models Groovy 90 that I have been flying with a Saito 125. I am thinking about removing the Saito and trying a gas engine. I was wondering if anyone has tried a DLE20 on the Groovy? The plane will just be a Sunday Flyer and not be used for any type competions.

Thanks

is the DLE a rear exhaust, does the Groovey have a tunnel down the belly, if so a pipe would give you a nice clean combo IMO.

How does the all_up weight compare? I was thinking of the same engine in my 1.20 plane. Would be my first gasser. Tins of good reviews on these motors. The next size up I think is a good pattern motor but maybe too heavy for us.

Let me suggest that you make the change. The DLE 20 has considerably more power than the Saito 125; run it with the stock muffler. Vibes and fuel consumption will drop and your toy will be much happier. Weight wise it should be a wash...the DLE is lighter but it has a CDI. Let me also recommend the Tech Aero IBEC IF you decide to go with the gas engine. It eliminates the second battery (5 to 6 ozs savings there) that typically drives the CDI. It is a far safer way to run gas engines plus you arm the CDI remotely with the TX. I use the retract switch for that. Plusits great to set-up your fail safe properly to disarm the CDI if you lose signal. You still crash of course but at least you're not chasing the model.

I have several threads in this forum that discuss all the details you need to be successful withthe popularsmall gassies of today.up to 60cc. Good luck

Thanks Guys. I am ordering a DLE tomorrow. I will post results.

You won't regret getting the DLE. I have helped set up a couple of them with stock mufflers and it could not be easier. Very well-mannered and reliable engines. As Matt said, the Tech-Aero IBEC is a must-have!!

Where is the best place to get a tech-aero ibec

Personally I dont't think fail safe should be set up to stop a combustion engine, but rather throttle back to idle, for two reasons:
1. An idling propeller will have a greater braking effect than a stopped propeller, thereby reducing the model's speed.
2. Often the radio link/control is regained after a "glitch", and you will then be able to make it back to the runway and land, instead of landing/crashing somewhere whith a stopped engine.

This is pilot's choise, of course.
