not gonna tell ya to go broke gettin something you want but the 9901/41021 is a great combo on the plus 4 and pretty darn sure you will like the way it feels and the mileage you will get with the proper tune on it


btw , 90$ is a VERY good deal

Currently breaking in two BTT's. Quite a ways to go yet. Both with 021 header. One on 9901ss and one on 9853ss. Would like to hear people's opinions about the power these engines make. Awesome or super awesome? LOL.

Can anyone tell me the size of the screws in the backplate of a Nova P5?

i think they are 2.5mm thread.... http://www.amainhobbies.com/product_...e-Cover-Screws

pretty sure its 2.6mm

Yep. 2.6mm which is the same size as Hitec servo horn screws.

yea that one lol

Thanks guys.

hey guys, i have a slight problem here.....getting back into nitro 1/8 after a little while. this time around, i want to start with a quality motor. car will be either an mbx6 or hara d8. motor-wise, i was stuck between the plus 4T or p5xlt.....can anyone point me in any direction??? oh, and i will be running mostly on medium sized/layout track, with a 2wd mod buggy/ebuggy trigger finger, and a jp3 pipe. thanks in advance!!!

disregard last post.....houston you have an order! thanks in advance

Wow! Thanks Scott , got it bro

Remember, that the JP3 pipe doesn't give any Novarossi engine a good mileage.

I had a jp4 a while back and run time was terrible try a 9901 or a 2096 they have worked well for me cheers

trust me guys i will...i just need to get this nitro car togetherfor now

Been reading most of these pages and I'm having some what of the same problem.

New 2012 (black case) P5xlt has about a 3/4 gallong through so far.

I've been trying to lean out the low end and reducing the idle gap as I go.

I have the idle gap almost completely closed. It is about at a .4 for gap setting.

I'm afraid it will stall eventually so when is the gap to small ?

It will not hold a HIGH idle unless I raise the idle gap !
