I have two neighbors whom I helped with their Savages this week (one brand new and on ~3/4 gallon). The 3/4 gallon one has not even been off-road...
I'm sure there are a plethora of tips out there, but here are a few I've seen first hand that might help someone:
1. Thread locking screws. The 3/4 gallon owner did not thread lock screws. I took off his engine and noticed the engine mount screws were loose (as in coming out). Only two of them were thread locked. I thread locked his mount and showed where all to thread lock it. I guess he forgot because 20 minutes after giving it back he was driving it out front and stripped his gear (his engine plate top screws were loose). I checked screws on the new Savage and only %30 of the screws that should have been thread-locked were. Reply to this thread if you need to know which screws as someone can easily help.
2. Shifting. The neighbor with the brand new one really wanted his to shift 'like mine'. He jumped the gun and started jacking with his shift poiny, but turned the wrong screw. That is VERY easy to do. I would not worry about shifting until at least a gallon. The shift point screw is extremely sensitive, so until you feel you have it tuned well and it's getting RPMs...don't touch.
3. Steering servo: I put a new servo on for one of them. He 'upgraded' his servo from the stock to one with 110oz/.20, which he got for $46.00. I suggested he take it back as he would see little if any difference, and for the exact same price can get one that has 216/.14, However the LHS guy told him it was 'better' so he stuck with it. I put it on and brought it over.....there was NO difference that could be seen (to where he thought i was pranking him). I then tried it next to one with a $5.00 servo (LOSB0819)...you could not tell a difference. I moved up the food chain and the tangible differences were first seen at 192/.18, with 216/.14 being a HUGE jump.
--Long-winded way of saying if you are going to upgrade servos, get at least 200/.15 or not point spending any money at all. If you just need to replace, $5.00 LOSB0819 works fine (I have some with over 4 gallons)
4. Clutch bearings. I believe in checking/changing them often, some don't. That's fine. What I can tell you is on the 3/4 gallon one...the bearings were complete toast. Seals gone from each one and and the bell was incredibly choppy when it spun.
5.TF-40 transmitter. The trim buttons are extremely easy to accidentally turn. Once stopped my engine to adjust slipper...dropped the transmitter and upon restarting the damn thing took off (when I dropped the tx the idle trim got moved). Check it before every start. The instructional manual shows how to check it in the 'Starting the Engine for the First Time' section.
I hope this helps anyone unaware of these items. Thanks
