Default e-starter climbing

Hello! This topic has probably been hit upon before but here goes.
my e-starter, stock, with eps 400 power system flew (barely) but straight and level. i put a 300 outrunner and a lipo LOTS of power but it climbs like crazy. it is very slightly tailheavy (it also was with the stock set-up) would that make it climb so bad? i tried trim on the radio but still climbs.
elevator looks real level with stab. would a change in the thrust angle help?
i found a stick mount for the outrunner so i used the stick from stock power system. if you need more specifics let me know and i'll post them , Thanks!

I would think you need to move your cg forward a tad to balance it. That big of a weight diff is going to change it, makes it tail heavy and yeah with that power she'll climb all day...

I know on my Beaver I had to do the same when I went with the 400 xt and lipo, from the geared, brushed and Nimh batts. After I added a tad bit of weight in the nose to get that balance back she flies great now.

A small amount of down thrust won't hurt. Also as Bill mentioned move some weight forward so it balances correctly. Add weight only as a last resort.

I didn't have to add much, 1 1/2 in washer from the toolbox was all! I moved the servos and receiver forward a bit and cut out about a 1/2 inch from the front of the battery compartment to move it forward as well, plenty of room in the Beav, don't know about the E though.

I've had a couple of the these planes. The built in thrust angle isn't sufficient for brushless flight. You'll have to change the thrust angle and add weight. Just like Bill said. Change the thrust angle first. Then get your cg slightly nose heavy. You should be good to go after that.

The other way to "fix" this is in the tx. Mix some elevator with the throttle. Tom

thanks everyone for your replies to my question! i've already fixed the cg and i'll add alittle thrust angle. now if the wind would let up some i'll get to try it!
thanks again!

Doing that basically will have him flying around in sort of a "flaps" mode. It sacrifices airspeed for level flight. Better to adjust the thrust angle.

Steve,

Yes, in a way it's a crutch. But you can use it as a fix at the field and get it to fly level at all throttle settings without rebuilding the plane. Adding reflex on the ailerons can also be effective and on trainers frquently makes them fly better. Just another option, Tom
