Very observant of you Sahil

This is a truly wonderful radio, with every possible feature except one - model naming. I can only give model numbers from 0-9. As I have only 6 receivers, this has never been a problem.

HiTec reliability is legendary. I have this radio since 5-6 years, although I have only been using it regularly since I returned to the hobby about 1 1/2 years ago. I have never had a single glitch or problem with it and the range is easily beyond the range of vision of a 40 sized model; about 1.5 Km +.

I have an Optima 6 & Optima 7 with telemetry (which I don't use - the sensors are too expensive)

I also have 4 clone receivers bought from Hobby King. They too work perfectly, are only about $20-22, but don't have telemetry. These are manufactured by FrSky. They give the same range and reliability as the Optima Series.

I have not used the Minima. I bought my Radio set and Optima receivers from rc4all, Chennai. I understand the range of the Minima is 400 metres, which although much lower, should be adequate. But the clones from HK were just so much cheaper and work fine too! No problem with Customs also - I got them by registered air mail, one at a time. Never paid duty or had any issues

Incidentally, I am using the original NiMH cells which came with the radio. 4-5 years old, but work fine. I get about 1 1/2 - 2 hours actual flying time, which is more than enough for me. Only thing is they tend to self discharge when the radio is idle. For that I have got 6 LSD NiMH from HK (the Tx is a 7.2 V system) but haven't yet installed them as the old ones are still going strong

Hope she survived up elevator recovery from inverted...
The problem with doing manouvers three mistakes high is that i can't quite see what happens...

Yes, the three mistakes high rule.

Frankly, I was flying < 1 mistake high. I do these things on other models too, this being a different and much faster model I was flying about 3/4 throttle, or about 70 Kmph. Came out of a knife-edge, I did get unsighted - at a distance the top and bottom wings look similar, thought it was straight and gave up elevator. Unfortunately it was inverted - famous last words 

IMHO the biggest damage was to my battery - a 30 flight old 3000 mAh Zippy LiPo 

I'm repairing it, will be able to do so, but my repairs are not that good and the models are never quite the same

Sir,
Lance's post today on the same subject:

Many near misses!

Yes sir, saw it 

Nice One Sanj... As usual superbly built plane that looks good too.... Tempted to build one.. Would love to build a plane with you one day.. it would be fun; you make it look too easy!

Safe landings..

Thanks Dee

Hi sanjay,

Even i got my stuff Hitec stuff from Rcforall, they have very competitive pricing or better than international sites even with all the free shipping, discounts and coupons  . Minima's are full range receivers without telemetry.

Good to have alternate receivers for Hitec 2.4Ghz especially in the micro rc range.

That's great news
