Spider 2.5E Carbon - 2.5m hotliner

Hello all,
I'm very excited to be the new owner of a Spider 2.5E Carbon. My wife got it for me SUSA for Christmas. I've already posted some info in the Electric Sailplane forum and got a lot of good advice. I'll post comments and pictures as I get time to work on it. With a 10 week old baby in the house that may be hit or miss.

I'll get started with some preliminary pictures...

The quality of the plane is excellent and it's a great value. I want to keep it light so it will thermal a bit, but want lots of power. So far I'm thinking of putting in a Neu 1509/1.5Y/6.7 on 6S1P. I'd be open to other options.

go for the 1512/2D on 6S.....smokin'!!

I have the 1512/1D on 14 cells in my 3M Trinity (also from SUSA, Thanks BOB!) with the 17x13 prop, and it goes up really nice...

Will 6S 4900's really fit in the fuz of that model? I thought it was somewhat narrow...

Ralph,that was my motor choise for 106 oz AWU Trinity.
With 18.5/12 prop and 6s1p TP2200 or EVO 2500 it produces 1400w of power.70 Amps.
Your Spider will be much lighter ,about 82-85oz.AWU so you may come down on prop a little and save some battery .
I am running 2.5 m Big Bird 80 oz AWU with Hacker B50-13S 6s1p 17'13 prop.1000W 55Amps. and very happy with results.

The fuse is basically a 55mm tube. The canopy opening is about 35mm wide. I don't think length will be an issue. I'll probably go with 2 3S1P packs because I have a Robbe Limit with an Aveox LMR10 that could use the 3S packs. Probably something in the 3200mah range. I may have to cut up some blocks of foam to see what size will actually fit.

This weekend I hope to start mounting the wing servos and linkages. I'd like some advice on how to mount the servos. I'd like to be able to service or replace the servos if required.

Epoxy? Goop? Polyurethane? Servo tape? Should I use frames?

I've been debating the 1509 vs the 1512. On 6S I don't think I need to go much above 80A to get the performance I want. I don't think the 1512 gives any advantage and is a bit heavier.

Can't complain, but I used to have an entire 600sq ft basement. I got married just over a year ago and moved to my wife's house. I built the barn, ran 30A service and wireless cable TV to it. It's got AC and a small heater.

Nice shop pics!

I'm a big fan of high voltage setups, but I think if you want to keep it light you could easily get away with a 4s setup and still have very nice performance - especially with the newer generation of cells (Thunder Power Extreme, FlightPower NF or NeuEnergy). Something like a 4s 3850 TP Extreme pack would easily fit, and setting it up for around 90 amps would be 25C bursts and give you around 1200 watts which should be more than adequate. Heck, even 800-900 watts on that thing would still be loads of fun.

Then you end up with lighter (and cheaper) packs, more room in the fuse and a cheaper speed control (because you don't have to go high voltage anymore). Then just pick the appropriate Neu 1509/6.7 that gives you the rpm you're looking for on 4s.

4S would be the most I could fit using one pack. For 6S, I'd use 2 3S packs, one behind the other. The fuse is fairly long.

I've attached a pic of how various 4S LiPo's would fit. All of the 3S LiPo's would probably fix except the 4900 or 5000mah. The length of each pack is shown on the pic.

Don't forget actually getting them in and out - the hatch opening may not allow as much without some dremelling.

Right. I'm planning to make some foam blocks tonight of the correct size for trial fitting. Assuming I can find my hot wire stuff in the rental storage building.

The 1512 would only be an advantage if you wanted to run much higher currents.....I was talking about 150+ amps....I thought you wanted a HOTliner!
