Estarter Brushless motor setup (Astro Flight)

RC Groups Discussion - Ultimate E-Starter thread?: "My friend just maidened his e-starter yesterday and it brought back fond memories He bought an astro 010 14t with the planetary 4.4:1 GB... it was pretty funny, with a 12x8 APC prop it made NO noise that we could hear over the wind... was kinda surreal Flew great too! He uses 3s tp2100's."

An Estarter setup

RC Groups Discussion - Ultimate E-Starter thread?: "Setup:
Stock 350 motor, 1080 props, CC pixie 20, 3xHS55.
Using either TP 2S 2100 or Kokam 2S 1500.
I install plastic rod (wing reinforcement rod from SS) from mid fuse to the tail. Also I use du-bro 1 3/4 main wheel & sullivan tail wheel.

The plane is tail heavy because of the reinforcement. With a little bit of clay taped to the inside of the cowling, now it is neutral. A little more nose heavy if I use the kokam."

Estarter tips: LG, reduce dihedral, stiffening

RC Groups Discussion - E-starter built and maiden: "I,ve put radio gear back into my e-starter this mourning since retiring her around July. This time used a gws 350, C gear and a master airscrew 9 x 7 prop with a collet adapter, cutting the gws prop shaft off at the threads. TP-2100 2s LI-Po for power. 'NOW WERE TALKIN' FASTER AND LIGHTER. Some advice, make the landing gear a friction fit into the plastic LG mount, this way the gear can pull out instead of tearing out, forget about the tail wheel and use a tailskid , made mine from 1/32 plywood. never has failed. An aircraft in flight has no purpose for a small wheel. After you feel comfortable with alerons, cut the wing at the center and reduce the dihedral to about 2 or 3 degrees, this will really quicken up the aleron responce, but be forwarned, you'll have to bring her out of a bank by appling opisite aleron, since removing the dihedral also removes the self righting characteristic of the stock wing, but gives much improved manouverability. Make your changes one at a time and only when you feel you need more out of this plane. I've found it to be durable and a good flyer, you did'nt need the bamboo in the rear fusalage, never broke mine there, but plenty elsewhere. Use stripes of scotch tape to stiffen her up where you think it needs it, wing and rear fuse. also crank in as much rudder as you can, its small and needs it. my 2-c"

Etec 1200mah amperage

RC Groups Discussion - Ultimate E-Starter thread?: "The etec 1200 cells are really rated to 6c continuous, 8c burst...you can't really infer from that that you can do 7.5c continuous... I found some places claiming that thunder power 2100's were good for 8c continuous and while they will DO it, you will damage the cells and/or get reduced capacity from them at those kinds of draws. I'd limit a 2s1p etec 1200 to 7.5a continuous... which in reality is more like 8a static or maybe higher depending on the prop."

RC Groups Discussion - Ultimate E-Starter thread?: "i reinforced my last e-starter with 3/8' spruce dowel rods the ENTIRE length of the fuselage (one down each side!), overlapping by 3' in 2 places -- that thing went through hell but the fuse never broke; only the nose got mashed up and the cockpit got damaged a few times... I did the same thing (1 3 foot 3/8' dowel) across the entire wing and that never broke either... all the wing damage would crack until it reached the dowel rod and then just stop... was hilarious."

RC Groups Discussion - Ultimate E-Starter thread?: "the Thunderpower 2S 2100 pack is the best thing going for the E-starter and 350 motor." [Perry at Aeromicro recommended the 3S 1350mah Thunderpowers with a bigger motor]

RC Groups Discussion - Ultimate E-Starter thread?

RC Groups Discussion - Ultimate E-Starter thread?: "I used some velcro on the inside and put some on the [battery] packs and I've never had that problem. The velcro keeps the pack nice and snug inside the compartment and even after the hardest landings it stays in place."
