Hey, i was just wondering what failsafe I should get for my Ofna Ultra LX Comp. Also when i try to run my buggy, it will bog down the more i pull the trigger and evently shut off. it is really hard to start after that. I have a .26 engine in it and i tried leaning/richening, new fuel line, new glow plug and nothing happens. Do you know my problem? Anyone can help. Thanks.

The absolute best solution would be a spectrum system for your buggy. But if you just want a failsafe, ofna makes them, venom makes them. They are all basically the same and are the same price, if i am not mistaken.

As far as your engine goes, it sounds like your engine is running too rich. When you give it gas it drowns the engine and causes it to shut off. After this occurs the engine is flooded and thus is the reason that it will not start easily. You need to lean out your engine. Lean starting with a small (hour like) turn and continue until the problem is resolved. Good luck...

Well with that buggy and engine your obviously not looking to go into serious racing, so a Spektrum system is overkill. So a failsafe is the better option, I use the GWS FS-01 it's around $20 -25 (£15) and cuts in on low batts, loss of signal, multiple signals and loss of crystal. Some dont have all these features and cost more, the Venoms have been known to cause glitching with digital servos and they are possibly the most expensive. The Ofna (branded) micro failsafe will fit in even the smallest radio box and tends to be the cheapest, I've seen them for $15 but many people have complained about them. BUT no matter what, should the batteries fall out, nothing will beat a throttle return spring (or elastic band).

Thanks for the info. i have tried to lean it and it still doesn't work. Do you have any other suggestions? I will check into those failsafes too. anyone can comment.

I say the same like Uberchav Alex.

I have an Ultra Comp and use the Venom failsafe (not the smart temp!). It has saved me from a runaway a couple of times. I have used it with both analog and digital servos without problems.
Another really good thing to get is a 6V humppack if you haven't already.

Your engine problem sounds like you got to lean it more. Just watch the temps so you don't lean it to much.

I'm not slating the Venom,just reporting what has been posted on thies forum (SEARCH), I have a Venomm F/safe and it works. But for less cash there is more |F/Ss out there that are just as reliable as the V but do not cost as mush.

And yes, you needto lean the Lsn a little more. I suggest you go back to the engines instructions and study them a little more.

i have two failsafes a gv models and a venom , the venom is still new and in packet aint used it yet, havent had no probs at alll with the gv and its a perfect size,

I'm using an OFNA failsafe in my LX Comp and have had no problems with it. It's nice and small and easy to set up.

On the issue of the engine. During break in I had the same problem and had to lean it out a little. The manual says to run it at 3 - 3 1/2 turns during break in. This is to ensure that you get enough lubrication to the piston and sleeve as they will be fitting very tight at teh top of the cylinder. Give it some time and of course when you make a change let it run for a good 10 seconds to clear the cylinder and carb so that you're running at the new setting. I currently run mine between 2 1/2 and 3 turns depending on the weather.
Hope this helps.

I had a Lx comp and I had lots of problems trying to start it. I don't know I had problems with it really cuz no one around here has a nitro car. I bought a Kyosho Inferno and that thing is so easy to pull start and keep running, I love every minute running it, but I also sacrificed some durability since I have broken parts on my MP7.5 and couldn't hurt the Ofna. My suggestion would be more expesive and getting rid of the Force 26 and getting a different engine, since I've heard and had problems with the Force running ect.

i suggest using a fail safe and a return spring. that is probably the best thing you can do
