I got my 3600 4S batteries in the mail, and they work out just right for fit and CG. I position the 3600 all the way to the back of the battery compartment (until it touches the "V"-shaped back side) for correct CG, just like I had the 3300 when the more lightweight stock power system was in the back. It's nice that I can use bigger batteries with no weight on the tail needed for CG. When I had the same power system in the Habu, I had to put an ounce of lead on the tail to balance, even with the 3300....because the bifurcated intake design of the Habu was more restrictive.
And since I will be using three different battery sizes, I cut down the aft one of those molded-in battery compartment obstructions to the floor, and put stickyback velcro on the floor. Plus I installed a second battery strap. So I don't have to hassle with different-sized chunks of foam to restrain different batteries. I glued the sidewinders on, and glassed the bottom fins, thinking that would protect against scrapes when tipping. Unfortunately, it didn't. I had a problem with tipping on one takeoff, after one main wheel got knocked a little askew on the previous landing...and the asphalt scraped right thru the glass job! I should have just imbedded some lite ply skids in the bottom fins instead of glassing. |

The only think I'd change about it is to lower the stance relative to the full scale model I really like scaling out 70mm models and there's little that has to be done to this model to make it look like a full scale with some good angled pics |

Put a few flights in this afternoon, taking advantage of some great weather. Fantastic flying jet. Just amazing. Eflite retracts were flawless.
Was there someone on the stock power system flying on zippy 4s 2800's? I seem to remember reading here that someone was running them? I've got 2 with Dean's plugs that I'm no longer using that are only 2-3 months old. Make someone a deal if they want them. |

I'll probably still use the zippy's for scale flights though, pretty happy with the batteries but to be honest I don't really believe they are true 30C... close enough though. I'm going to test and see if they sag too much or work with the CS10 fan and 2800kv motor. Initial readings with that fan for me aren't as drastically different from a 5 blade like everyone says for some reason. Maybe it's the zippy's holding things back. Not sure yet. For anyone running stockish power though they certainly do the job. Got a lot of use out mine and work just like new. |

I agree about the C rating. I don't think they're 30 either. But a pretty good battery and great weight and size-fit-wise. Let us know what you get out of that CS10. I'd be interested. Thanks! |
