OPTIMA Receivers for Indoor & Parkflyers & Alternate Antenna.

I am a sailplanepilot and it is hard as it is to fit ordinary 2,4 GHz receiver antennas in the plane.
Today i use Mpx Royal Pro with M-link and I am happy with that, but as said,
I would like to test the Hitec system, especially as the price is so good.
Two new 6ch Minima, (provides for separate aileron servos) one with end block connections
and other with top block servo connections, without telemetry, will be released early 2011.
1. A smaller antenna can be used, as detailed links below, but return telemetry distance is compromised,
as supplied unit also optimises transmission from RX.
2. Why hard to mount? the slim length made installation into a user's HLG a breeze (antenna down inside FG tube)
- only the very tip needs to poke out if C/F.

fitting a shorter, lighter alternative for Park Flyers, Indoor etc.

Lightweight modification 02 - How to change antenna using a Digi-Key Part #: A36229-ND
(Leave something like a 6" antenna and then strip the outer sheath off about 1" of the tip.)
Optima 7 converted for small model use with picture. Case removed they weigh just over 0.25oz. (8g/10g).
Optima 7 Indoors Hitec "Factory Pilot" Brandon Chitty uses the Optima 7 in his indoor competition aircraft
(Fancy Foam Maxima) that weighs 8oz, as well as his 170CC DA powered
42% Aeroworks Yak, so the Optima transceivers are very versatile.
