Ok a few things to consider here. First the Drake kits has all the good stuff in it. Threaded shocks TI turnbuckles and and its graphite. Now if you get the drake kit it comes with the rear header that is for bumpstart only. With the regular kit you are going to be able to get it with a stock header and pipe.
As far as buying the kit a month ago I would say get the Drake no questions asked. The average prices of the Drake was around 300-330 and the regular kit was floating arong 240. Now on ebay you can find the Drake in the 280-300 range from hobby shops that sell on ebay. You can find it at online retailers for 319 at stormer or rcpitcrew those are the best i have seen from an online store.
Now here is the delima if you dont care about getting the graphite. The for some reason the price droped over 100 dollars on the xxx-nt kit. I Sold my rtr a couple weeks ago simply to by this kit it is going for
134.99 at ultimate hobbies That is a steal then all you have to add really is
Lunsford Racing XXX-NT Turnbuckle/Pin Kit 39.99 RPM Long Shank Rod Ends Now if you dont just have to have the graphite and threaded shocks then this is a really good option at 180 total.
Also the turnbuckel set ha ti hinge pins and the drake dosen't so add another 20 to the drake. You can save over 120 bucks going the second route if you have the money sure get the drake if not do the second option.
As far as if you need a pull start motor if you get a pull start and want to use the drake you can just use the standard header instead of the drake one.
Now on the engine there is no reason to get a .15 for one of these trucks they are so light they FLY. People have diffrent opions on weather or not to use a slide carb on stadium trucks. They say it is not as sensative to throttle response made more for a rode car. If you want a kick tail engine for a great price this is it
O.S. .12 CV-RX w/10C Slide Carb On-Road $124.99 Tower Hobbies and it has a pull start so there is no need for a starter box. You can also use a starter box with a car that has a pull start also I like that personally that way if my truck dies in a wreck I can have buddy restart it for me asap.
Now if you want a rotary carb instead then I would say that the OS CV-RX rotary is the way to go for reliability and tuning ease or you can get a fantom from Stormer or on ebay for a better price. I have never used a Nova motors but I hear they scream but they can be touchy to tune. Anyway thats my input.
Almost forgot put a RPM front bumper on your truck before you even start it and that will save the heart ache of busted from a-arms. X
