Ill take the bait thats offered - bite...[X(]
Welcome to the thread as such.
If you are familiar with the 2speeds from other trucks and cars...then the HPI version is no different in that regard. I would perhaps suggest that you take it out and look to see if its getting stuck or is stuck due to over adjusting it - has hapened to me with my revo 3.3 as I put in a new .26 iin there and there fore had to change the set-up a little and it was slightly over adjusted and consequently got stuck, so it was only running in second gear. My 2speed is a wolf pack radicals and is essentially the same as any other in some ways.
Also you engine may not be building up enough rpm to change gear anymore...? What wheels and gears are you running BTW?
Your spring may be cought or the little ball under the spring may be pushed too far in? Its hard to say as I cant see what your talking about. But the 2speed is a VERY simple device with essentialy very few moving parts, therefore there is not much that can go wrong with it.
Things that effect it:
1) SG 2) CB 3) wheel size 4) engine size and configuration 5) 1+2= no rpm if the sellection is not matched to your engine and the trucks use.
What is your gear sellection?
What is your wheel diameter....?
What is your slipper set at?
What is the condition of your clutch?
IS there some drag on the drive train that is slowing the the truck down stopping it from reaching the right RPM?
You really need to give more information as what you have said is not much really...but ill try to give more info later when there is more to go from.
Or call HPI and try to get some info. Or you can take it to your local Hobby shop and show him...?

hey guys , just a couple of questions 4 ya over here in hpi land!!! I sold an mt2 rtr to a friend of mine about 2 weeks ago, i sold it to him due to the fact the engine was gone in it ( i bought it this way and never spent the money to put a new mill in it , so i never really got to drive it all, the guy i bought it from had it for about a month and didnt break the engine in right so it went to nitro heaven early lol ) but anyway he had me put a O.S .18 in it and it runs great well he wanted more top end so we put the two speed in it, we got it too shift like twice when we first put it in and ran it the first time and that was with the soft spring in the 2nd gear now it wont shift at all and i have tried everything with it ...... i do know how all this works casue i run my NTC3 with the 2 speed in it weekly and compete with it from time to time ..... so im not a newb just not tooo good with hpi....... soooo does anyone have any tricks or tips for this 2 speed to get it working or any ideas what it could be????
