That method works well too, but I prefer to wind the majority of the string onto the spool before placing it in the PS housing. Then it's just a matter of a single extra winding to tension it.
Getting rid of the slack is pretty easy. With the spring and spool in place, rotate the the spool counterclockwise by hand until you have about 10cm of slack in the string. While holding the spool in place to prevent it from springing back, wrap the excess string around the spool in a...
I currently run a Picco 28, previously an LRP Spec3, and I can tell you that both of these engines will smoke the competition. If you're going to get a new engine, get one of those 2. I give the edge to the Picco in terms of raw power, but the LRP has the advantage of being easier to break in...
You may have cracked the sleeve around the one-way bearing. Sidewinder Race only contains 12% lubricant, only 2% of which is castor oil (The other 10% being synthetic lubricants), so it doesn't cause the OWB to slip under normal circumstances.
Remove the engine's backplate and inspect the...
I've never liked Roto-Start units, mostly due to the terrible quality of the hand-held starter. I ended up breaking about 3 before I started using a high speed cordless drill. Now I exclusively use pull-start units, as a properly tuned engine is never too hard to start, and I don't have to carry...
This is a decent quick fix, but if you don't need to repair it within minutes, it would be better to use rubber cement. That would give you a flexible bond that will withstand impact. CA glue has very little shear strength and might split apart during use.
Removing the anodizing will only decrease the surface hardness of the parts. It won't effect the strength. It will also change the dimensions of the parts by a few micrometers, but that shouldn't be a problem.
As for the original question, I have used the Integy parts you mentioned. They are...
It's called vapor lock, and it's completely normal. When the engine is running, the constant flow of fuel through the carburetor keeps the fuel port fairly cool, below the boiling range of the fuel. When you shut the engine off, this flow stops, and the port heats back up again. When you try to...
It depends on which fuel you are running. High-end fuels like Byrons contain extremely good lubricants, so if you are using something like that, it will take forever to completely break the engine in. Low-end fuels like HPI and Traxxas fuel don't lubricate as well, and will allow your engine to...
