Turbojimmy,
The guys name was Chris Webb, huh? Unbelievable !!!

As for starting the engine with a cordless drill, there isn't much clearance. It would be extremely difficult to do so.

Yes, Chris Webb. I was very confused when I got the e-mail after having seen your posts here. I thought maybe someone was having fun with me.

Anyway, it's a shame because there is almost enough clearance. I have a 12mm 1/4" drive socket and a 1/4" universal w/ an extension. I can't get the socket and universal on with the engine installed but I may be able to do it if I put it on the crankshaft and then bolt the engine in place. I suspect the crankshaft is pretty fragile, though, so I don't want to make matters worse.

EDIT: Here are some pics as it sits on my workbench (they're big, but I left them that way so you could see the detail - seems to be a decently built truck):

I agree.
This looks like a pretty solidly built truck. The twin-plate-chassis design makes it pretty sturdy.
Two things I would've liked to have seen:
1). A slipper clutch. When this thing lands from a hard jump, a LOT of stress is going to be put back through the drive train and onto the center gear. Luckily it is metal....
2). Adjustable upper links. We can adjust the toe in/toe-out on the wheels, but cannot adjust camber.

Turbojimmy,

Did yours come with tire foam inserts? Mine did not; I had to go out and buy my own.

No, there's no foam in there. I'm new to the hobby so I didn't know the implications of that. I don't think they claim to have foam inserts on the tech specs anymore. I don't plan to do a lot of hard jumping with it anyway. If I do I'll probably get different tires w/ foam.

Jim



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 2:55:04 AM)

Tire foam makes life a lot easier. With tire foam, your tires wont seem flat.
I've heard from others that have this truck, that they've been able to run theirs just fine without tire foam.
As for me, I don't plan on much jumping anyway. Mostly tooling around my neighborhood with it. I bought it because it's just something different to have. Everyone else seems to have an HPI Savage, or a T-Maxx, or a Revo, or a Warhead. While those are all good trucks, I like seeing something new.
This truck looks good and strong and has a lot of potential. I would guess it would be able to keep up with a Savage or a Revo. I can't wait to get my engine back and get this thing running again.
(well....I guess I have to wait.....26 inches of snow where I live....no driving for a while).
If you get your truck running, let us know how it performs.

Pics are great !!
Like I said before.....once I get my engine back, ITS ON !!!



dracy69 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 3:40:38 AM)

too bad NY isnt getting any snow anytime soon[&:]

best of luck with the truck, hopefully you can have fun playin in the snow.



muck76 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 4:11:58 AM)

there is a roto start that turns 90 degrees and would allow you to start it from the top.
Yes snow is fun!

Tower sells a starter for it, but it didn't seem worth the $36. But if a recoil starter is $15-20 and they break after every 4 or 5 pulls it may make sense.

Jim



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 2:28:50 PM)

Yeah, I was debating on whether or not I should spend the $36 for the roto-starter that Tower sells.
My pull-start broke too. Before I sent my engine in, I stopped by my hobby store and had them put on an HPI pull starter. That's what I've been using ever since; no problems. They seem pretty durable.

One issue I'd have with the $36 starter: it is compatible with other engines? In other words, if I bought a new engine one day, would I still be able to use the $36 starter on it, or it is limited to the Tower .25 engine.

Do you have a part number or any description of the HPI recoil? I'm running down to the hobby shop in a couple of hours. He's going to ask me what engine and I don't know other than it has the Tower Hobbies logo on it.

Jim



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 4:11:00 PM)

Unfortunately, I don't have the part number.
Just bring your engine with you.
Pretty much any recoil starter (that will fit .21 + size engines should work).



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 4:18:08 PM)

Turbojimmy,
Here's some pictures of the HPI pull-starter that I've been using.
The instruction sheet says it is the HPI Pull Starter Assembly 21BB
It fits onto the Tower 25 engine.
The only problem with this particular pull-starter: only 3 holes for the screws to attach to the engine (the original Tower .25 pull-starter had 4 screws). But it works fine.



turbojimmy -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 6:01:18 PM)

That's the one I got. I told the guy HPI for a .25 engine and that's what he gave me.

I ran the first tank of fuel through it. It's running really rich, which I guess is right for now. It's smoking and fuel is coming out the muffler. It won't idle yet either. The more it ran the better it ran. I'm going to lean it out a bit for the second tank of fuel. I have to feather the throttle to get it moving and then keep it steady to keep it running. If I let off or give it too much gas it quits. Once I lean it out it should be better.

It's also 36 degrees today which doesn't help. I pulled it into the garage too fast and flipped it. With no body on it, it beat up the cylinder head. The first of many wounds I guess.

Jim



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 6:07:28 PM)

Turbojimmy,
How does your engine run when throttle is applied?



turbojimmy -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 6:10:06 PM)

It wants to stall, but that's because it's too rich. If I work the trigger on the transmitter to 'feather' the throttle I can get it to move on its own power. I can't just 'gun' it though because it will stall (flood, I assume).

Jim



turbojimmy -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 8:46:21 PM)

I got it running pretty good now but there are still some issues. It's cold and raining so that might have something to do with it. In order to keep it running I had to open the throttle stop up a bit. Now I have it turned the whole way out and the thing is idling VERY fast. If I richen up the low speed mixture it will calm down but then it will stall when I give it some throttle (too rich - floods). If I lean out the low speed, I get a good transition from idle (if you can call it that - it's fast) to throttle. It will run hard but break up at full throttle. If I run it hard for too long it will 'idle' so fast that I can barely stop it. It's obviously lean because it gets hot fast. I pinch off the fuel line to stop it, let it cool, then it's good again for a while. I think there is some fine tuning I need to do. I've run about 3 tanks of fuel through it and it seems to have 'loosened' up nicely.

But it does go stupid fast. The 4WD on the wet pavement makes for a lot of fun, too. And it rips up my lawn, which is neat.

Jim



chriswebb70 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 9:07:44 PM)

That's great!
I'm glad to see you got yours running.



muck76 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/22/2006 10:56:58 PM)

Jim did you wrap the head? With temps that cold it needs to be done. With it being done, the fine tuning will help with the idle. If it is idleing high you amy need to adjust the idle screw. I thought the manual explained this some. Other wise the Traxxxas engine manual explains it very well.
Also you can use zip ties on the top pf the head to help prevent damage to it. I can not find an up close pic of mine to show you. If any one else does please do.
Glad to hear it is running well. I wish i had the $$ to get one. I am going to wait until after xmas and watch for one on towers scratch and dent sales.

I did not wrap the head. I started it in the basement (around 65 degrees) and let it idle until it was warmed up and then brought it outside. I was afraid of overheating it during the break-in.

With the idle, the manual said that during break in you might have to bump up the idle to compensate for the rich mixture. I did, and then I had to back it off. The manual also said to keep the low-speed and high-speed mixture screws at the factory set 3 1/2 during break-in. However, tech support said to do whatever you need to do to keep it running. I started at around 3 1/2 on the high speed screw and have it down to about 2 1/2. It runs really strong but still breaks up at high RPM. It's still smoking under acceleration so I think it's still rich. It's going to be mid-40s tomorrow so I'll see how that changes things.

When it's cold you need more fuel right?

It will still get that crazy high idle where you can just tell it's getting hot fast. I shut it down when it does this. It's only after a lot of beating on it. Normally, the idle is good and a little on the rich side at the 3 1/2 turns of the low-speed screw.

The head won't get damaged on a flip if the body is on it. I've been running it w/out the body per the manual. I think it's pretty much broken in so I'm going to put the body on it (if it ever stops raining). It's definitely too fast for my street. My cul de sac is only a couple hundred feet long. One wrong move and it will smack the Belgium block curb and that'll be the end of the fun. There are a few wide open spaces I can take it to tomorrow in order to really stretch its legs.

Thanks everyone for your help!

Jim



turbojimmy -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/23/2006 1:16:56 PM)

Another thing.....I found that the HPI starter is better because it has a longer support-thing so it will stick out of the body. I tweaked the body (cut it) very slightly so that I can start it with the body on. Now I just need to route the fuel line so that I can pinch it with the body on, too.

I attached a crappy pic of the pull start.

Jim



Downhome4x4 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/23/2006 1:42:44 PM)

just put your finger over the end of your pipe it will stop instantly. that's what i d and it works great



muck76 -> RE: Tower Hobbies Nitro TOWER Terror MT .25 RTR (12/23/2006 4:47:35 PM)

wrapping the head allows it to heat up so you can richen it. That is better for it in the cold.
Other wise with it cold outside the air is thin and you will need to lean it to get the engine up to running temp. This is not good to do it lacks too much lube then.
