Default DLE 20 choke lever

Hi guys can someone post a picture of the choke mod which a few guys have done so i can choke it from the front of the cowl. I am also wondering if i really need to use non metallic throttle linkages between the engine and the servo as it seems like there will be too many spots where it could fail if it starts to wear. Why cant we just use full metal pushrods.

linkage with metal rod 4-40 and metal clevis or dubro ballink works best for throttle. dont trust the plastic stuff and use an analog servo on throttle

My flying buddy used a long bolt attached to the choke lever. Reach under the cowl and pull the bolt head back to choke, push it forward to fly. I would not recommend a metal throttle pushrod, as any metal-to-metal vibration can induce ignition noise into the radio. Best to use inner and outer nyrod for the throttle pushrod. Even though it's only a 20cc, a transmitter-operated kill is recommended. They're cheap and easy to setup.

Can you recomend a cheap remote kill system and will metal to metal bother 2.4G systems?

"Cheap" is relative...the servos alone on my plane cost over $700...I'd rather not trust a $29 ignition kill if I needed to do an emergency shutdown. I use a $50 Smart-fly fiber optic kill...it's cheap relative to my servos, my $600 engine, etc. One of my flying buddies uses a relatively new ignition kill and battery eliminator unit...it seems to be working just fine...rcexl and wiki rc are probably the least expensive units, but I don't have any first-hand experience with them. 2.4 is not immune to electrical noise interference. Even with 2.4, if you cross an ignition wire with a servo wire, or have frayed shielding on a spark plug wire, you'll likely have servo jitter. OTOH, lots of guys use one battery to provide power to the radio and ignition. A lot of guys also fly with only one battery and one radio switch too. With my GS stuff, I prefer to use quality, proven components, and redundancy. Hope that helps.

Here is what i did. Reach through cooling hole with pliers and pull the rod to choke. Get engine to fire and push the choke off. No cowling cutting required. I have since revised throttle setup, If you need pics I can post them.

That will work Joey but its a bit rough, a bent push rod and guide is much better, i will post a pic later when i get a chance.

There are pics on the thread I posted the link for. Its a servo arm used for a bellcrank with push rods on either end. A small clamp is used to hold the push rod in the front.

The pics I referred to in the above post would be of the changes to the throttle linkage. I will try and post everything on this post when I get home from work tonight.

I use the one from Southeast engines, the opto-kill on this page . http://www.southeastrcengines.com/see_024.htm
Have 2 of them and they have been very reliable.

First pic is of original configuration before changes to throttle. After the maiden flight I found the throttle too sensitve and hard to modulate. So I turned the metal arm around, added the fiberglass arm(included with the engine) and readjusted everything. On the ground with my short tests (dont want to make neighbors mad) it seems to work much better. It also removed alot of play where the z bend was in the throttle rod. I will let you know how it works, looks like I wiil be able to retry on Fri (Yes New Years Eve).
You can see the choke rod in the last picture of the front of the cowling.

Hey All,
Well, after 5 full years, we have decided to call it quits.
We will slowly close out our stock and warranty our engines purchased before 04/15/2011.
Nothing to do with the fine quality of RCGF, but because of the Chinese market.
There is a company (from China) that will soon have store fronts in the USA and will take out all
of the smaller companies like ours.

RCGF has been good to us and we thank them for that.
They manufacture next to perfect engines for our USA sales, but sometimes (most times),
the price is the only matter.

We see the writing on the wall and will let their new distributor enjoy the sales.

Stop by the website for low low close out specials: www.southeastrcengines.com
