Which Watt Meter?

[muscleflex]

I'm looking at getting one for my Parkzone Sukhoi SU-29 SAFE

Will this be sufficient?

That would be more than sufficient for what you're after although I cant remember how much space you have in the Sukhoi.
I bought one of these as it smallish and slim, so I could fit it in most models to get a better idea of what's going on in flight, although I have swapped the deans for XT60s. Its also a similar spec to the HK one.

Its pretty good quality and seems accurate enough. It also stores peaks of Amps and Watts, and lowest voltage since switch.

Yeah, that one looks like it would do the job just fine. Personally i only ever use the watt meter for ground testing a new setup, I never fly with one in the plane. Ground test with a full battery will always give your maximum reading, in flights watts/amps will generally be a bit less.

You can get one on e bay, rather similar to the above, for £6.35 inc. postage. I can't vouch for the quality but I will when mine arrives.
