I would keep it simple where possible on something that size, less bits to go wrong. Just make sure the parts you use are decent quality, and connected together with decent cables, well supported and neat and tidy.

The only place where I would consider spending a bit of money, or having a redundant setup, is the receiver power supply. Either use a failsafe switch (a solid state one, that can't fail due to vibration, or dirt) or a dual rx pack and two mechanical switches.

As for wanting to use multiple receivers, why bother? You only have one transmitter module/aerial.... The multiple receiver aerials on 2.4GHz rx's do the same thing anyway.

Plus, with less guff onboard, think of the weight savings Smile

You could possibly consider using one of the AR9100 receivers instead? It has the failsafe switches, and Dual battery input built in as standard. It would work out rather much cheaper than the two PB switches plus AR7000 too.

Also, for the batteries, two 3300 batts will see you flying pretty much all season off of one charge. You could quite easily have a comfortable afternoons flying on two 2000mAH packs (Or A123 packs if you want to build in some ruggedness, and dare I say it, crashworthyness" to the equipment on board)....

Cheers!
Andy

You obiously missed the part were I said use what I've got lol

If you were there on Sunday you would have overheard a discussion about A123, these may be used if I require weight in the engine box, (Id rather have solid cells attached to that) if there going in the fuse then lipos are the way.

Ah, just testing......

Don't forget that Lipos bring in the requirement for regulators though (and add another possible failure point to the equation).

I was wondering about coming out to play for a bit on Sunday. Instead, me and Daisy decided to storm Conwy Castle instead....

I'm sure safety is the critical factor when fitting out an airplane that just might go to a show or comp where paying visitors are present, the amount you save in weight is not really an issue with a 50cc petrol model as long as you don't overdo it.

I just happen to have a Gemini & two Lipos ready for my vision when it arrives.

And it's a 58cc engine so power won't be limited.

Just my thoughts

To be honest Rich thats somthing on my mind, with all the fly-in's I do and hopfully a few comps I want it to be safe (should let somone else fly it then). So dual batts/switches is a minimum.

You're right the 58 should haul ass!

A visit to Richies tonight confirmed my RL58 is indeed 1252g w/o and his DL50 is 1350 w/o

Intrestingly the engines share a few similer parts but on a whole there very different. Although bolt spacing look to be the same.

Thanks also for Rich helping me out with the throtle links
