If you want a .28 the GRP is probably a good choice, I haven't driven one but I heard it's very smooth unlike most other .28's

If you want a .21, I use a Novarossi 21-5K - it's perfect for a truggy in my opinion. A RB C6 is probably another good choice. I currently run the Orion Wasp in my buggy, it seems to have plenty of power as well.

You'll need a servo with a lot of torque for the truggy, When I had the CRT I used a JR 9000T, plenty of torque and pretty quick too.

I personally like Hitec servos, something with 300 oz or more of Torque is great for a Truggy

i have a chance to get a wasp pretty cheap. i dont know which one it is but it sells for $280. i heard it has a lot of power but is hard to tune and keep seals in. i dont want something i have to keep adjusting. a few times a season would be fine. before every time i run it, i will want to get rid of it. i was also thinking about a picco 21.
do i need a high torque servo for the throttle and the steering? i was thinking a metal gear for bothm but a high torque for steering and a high speed for throttle and brake.

To be honest, The Orion Wasp CRF Rev .21 is my first experience with a engine that use a Picco case and Carb (the guts are completely different). I have noticed a small problem with the carb, it seems to lean out when the fuel tank gets low, just a minor problem thought, a little lean bog, I was told that the picco carb leaks air when they are hot, I've sealed the carb but haven't had a chance to run it yet. Other than that it's a breeze to break in and is relatively easy to tune.

The GRPs (I've had several Ninjas) can be a little tricky to tune sometimes. They seemed a little more sensitive to weather changes.

The Novarossi 21-5K holds a pretty good tune

Keep in mind every engine has it's characteristics, you really can't go wrong with a good brand name from Italy or Japan

Yes, I would suggest a servo with a lot of torque for the Steering, and sacrifice some speed.

For the throttle it's up to you, I think most guys like a fast servo for the throttle, but for me, on a Truggy I actually like a Torque servo for stopping power

The Picco .28 can be a little tempermental until break in is complete. Once the break in is done it's a breeze to tune. I personally like the JPX .21 for my truggy. Tons of power and easier to tune. The P7 Evo3 is also a great motor but is a little softer on the bottom than the JPX motor. Same exact motor but the crank is different.

Today, the .21 engines are really being built with plenty of power, I would suggest a .21, you'll have power and better fuel milage.

A friend of mine has the Jammin .21 as well in a buggy and says it plain out rips!

im starting to see that alot of people are perfering 21s. i am leaning towards something in the picco line. i have been told the os vspec would be good but the price isnt. then a pipe and all the other goodies after that would have the wallet and the woman screaming at me.

thanks for the info everybody.

www.nitrohouse.com

JPX .21 = $229.00
OFNA 053 pipe = $53.00.

Can't beat that and it's just around the price of just the Vspec alone.

That's one of the best combo's that the Ofna guys run. Awesome top end and bottom galore.

i looked at the site. what about the 063 pipe. i dont really want to lose it comming out of a corner and with the bottom end pipe i think that would happen easier. any experience with the mid range pipe?
