im so angry right now at my motor... it stood untouched for like 6 months... i tried to run it a while ago an all was ok.... today i walked to a field (4miles in 1 direction) and could not start it.... and when i finally did start, 4 times out of 5 it started backwards... and when it did not start backwards, there was nearly no difference between idle and WOT... like 10% more power at wot than at idle... i tried all kinds of needle settings... leaning low, richening high, leaning both, richening both,etc, etc... made no difference... im soooo bummed...

Which motor?

The backward starting sounds like an OS. Mayber there is some gunk in the carb.

6 months is a long time to sit if it had any fuel in it imo.

Not RC... but I had 7 generators that were bought brand new. All started fine and about 1-2 mins in all would not run right. The fuel that sat in the carb had gone bad and all required disassembly and cleaning.

I used to walk ten blocks with a T28. I thought that was crazy.

8 miles with a 71 and all the support equipment...you're dedicated to say the least!!!

Wow! I'm blown away! Freakin' LOVED my Slick this morning on the 7955's at 8.5v!! I just felt world's more connected to the plane!

All the maneuvers were much tighter and the high energy stuff was much more violent. Loving it!!

Also, I put a watt meter on my setup and I'm only pulling about 65amps and 2,000 Watts with the 4325-310 with a 19x8 prop on it. I wonder if I can go up to a 19x10?? Or maybe a 20x8? Anybody try going that high yet with this motor? I'm guessing I'd be pulling well over 2,500 Watts which would be problematic so maybe I'll just stick with what I've got as it's certainly working just fine!

Awesome, glad your digging it. You will see close to 500W more power with the 20x8 or 19x10. The spec for the motor says 2500W, so at least this time of year you should be alright. Summers maybe a different story, keep a eye on temps if you can, and you will be fine. 20x8 was way better for me then the 19" props I have tried, but I like big props. (14" for 48", 16" for 60", and 20" for 71")

thats awesome, just another testament to putting quality servos in a plane.

as far as power, if you are happy with the power, no reason to change it. you will lose flight time, and make everything run just a tad warmer (although that last point really doesnt matter). also dont forgot the plane's habits will change with more power, so if you are dialed in and feel like you have plenty of power, dont change a thing

welcome to the world of hv. how did you get 8.5 v? bec pro or the 10 amp bec? also, what cell count lipo?

I've been running 3s 1000s, but I was thinking about doing a 4s 800 instead, with the reasoning being that if one cell dies on the 3s, I will likely drop below the required input voltage. however if one cell dies on a 4s, which in my experience is the most common type of lipo failure, I still have plenty of voltage to keep the BEC pro chugging.

bec pro can go over 9v

I thought it was limited to 1 v increments though.

damn I should just man up and buy a copy of windows or a little netbook or something so that I can run the castle software. especially now that literally the only person I know with a windows rig just moved away.

LOL... my hobby is the only reason I own a PC

Yea, what everyone else said. In using a BEC Pro and it will increase in 0.5v increments once you get up that high.

My Slick was awesome before and now it's ridiculous.

This is for those who are debating about installing fuselage side reinforcements.
Man, I wish I would read this thread before last weekend.
Oh well, it was fun while it lasted.
