If I get into my posession a F4.1 with a rotostart backplate, could I just purchase this, change it out, and be up and running?

Also, is it possible to use a different, cheaper one?

What kind of truck is it going into?? Im not sure if this pull starter would go straight on or not?? It depends if the back plate is compatible. Im sure one of the other guys will give you an excact answer..I think dracy69 has an X he may know?

i use one of those to replace my S-25 roto. if the F4.1(Savage X's) only been modified internally, then it should fit... in a savage of coz.

Err, whoops. It's going into, what I believe, a Savage 25. Bought it second hand, all savages look practically the same to me right now (have an E-maxx)... The F4.1 is comming to be out of a 'chop shop then on ebay' Savage X I believe.

Also, if anyone has the hand held part of the roto-start they are willing to get go with for cheap...

If you already have some 7.2 volt packs laying around, you can pick up the start unit for around $30AU. Where are you BTW??

Yes that is the part you need.

I just bought the roto-start package for my 4.6, I may be interested in parting with the handheld starter - as I plan to use my cordless drill. Let me know if you are interested, I don't have it yet since I just bought it on Ebay last night after I tore up my pullstarter.

i prefer pullstarts realy....wen a rotostart has a dead battery and dad is at work THEN uR SCREWED lol..i got my own cordless drill with 2 batteries n all but i never use it ... i just use my dremel for all the drilling n stuff or my dads dewalt..hes got the big 3 speed XRP lolllll 18V power...INSANE I TELL U

I live in Hawaii, and would truthfully only consider a rotostart assembly for $20 including shipping...

I was looking around more on Towerhobbies, and would this Ofna pullstarter work on the HPI engine?

EDIT: Looked around more; would this pull starter work on the F4.1?

If the pullstart fits the old HPI .21 or .25 engine it will fit the 4.1.

What if it's for a different brand engine?

All I know is if it fits the other 2 engines I mentioned, it will fit the 4.1. Sorry I cant be more specific but I don't have any experience with Ofna pullstarts.

I ended up buying the HPI pullstart for $26 from my LHS. Ouch, wished it could be less... Then again, the rotostart, handheld part they were willing to sell me was $40. If I go back before I start it up, I will hope they have the $5 starter shaft I can use with my drill.
