Just finished up a new .15 Profile for this year -- Basically it is an electric version of the model in this photo:
http://stunthanger.com/smf/carrier/15-carrier-at-hunterville/msg405252/#msg405252In looking back, I found I've been flying that model for a lot of years (found mention of it in a post from 2008!). It is built from a Cartier foam wing (Lil Hacker) and is 'sorta' scale of a Grumman Wildcat. It has had 4 or 5 different engines on it and has been flown by many others besides myself. Last year, I took it to the Nats and if I had been able to get anywhere near the speed limit, I might have given Eric or Burt a run. Still had a very nice flight. So ... time to try and improve it.
This one is closer to a scale Wildcat and the electric motor promises to outrun any of the glows I own. It has a NTM 3536-1400, running on 4 cells, with an 8-5.5 Carbon prop. Turns it at 18000 rpm, and draws 55 amps at high speed. I did some test runs this afternoon, and after 30 seconds of High speed, I ran 4 1/2 minutes at 25 amps which I estimate will be the current draw at a very nose high attitude and during a landing approach. When I started a recharge, I was at 30% charge, so there is even room for more if needed.
I'm using the new Hyperion "High Voltage" LiPo's, which require a special charger. These are somewhat lighter and have a higher capacity than 'normal' lipos. Instead of 2200 mah, these are rated at 2400.
I'm looking forward to a chance to fly it before our June contest - but the wind here has been off the charts all spring.
The battery sits on a plywood shelf (tied into the fuse) under the wing cutout - that bridge-like piece over the battery replaces the removed section of top-spar. The ESC is mounted to the bottom of the shelf with tie-wraps.
I was actually playing around with some other ideas on this one - so the wing is foam covered with a polyester fabric and elmers glue. Then I ironed on some of the Cartier SLC (and the tail surfaces), scuffed it with scotch-brite and sprayed on Rustoleum. After the stickers were added, I sprayed with Rustoleum Satin Clear. Final weight is 30 oz.
