Royal Kit for Bleriot Mk XI

Firstly, if this model were built for 'glow' you might use a 40/46 but would be stooging around at part throttle for most or all of the flight. as such, the E46/G46 motor is going to be way too powerful for this model. The lighter G32 would probably give ample power, however...
...secondly, the model has a short nose and might benefit from a heavier motor, so the E46/G46 might be spot on.

Finally, if the model does balance tail heavy, you could use a bigger battery, say 3000mAh, instead of the 2200mAh...better to have a longer flight than carrying around lead.

Phil - Been doing a few basic sums based on your data, Mike just got in ahead of me.
I'm in general agreement with Mike & here's my bit.
The E46 & G46 have identical specs & are rated at 40 A continuous, based on 4 cell LiPo this will give around 640 Watts.
With the model weighing say 6 ibs you have on tap 100 Watts / pound ie plenty in hand.
The wing area & weight given equates to a wing loading of 24 ozs per sq foot so the extra power may be a benefit.
Flying around on half throttle ( 20 A ) you will probably get around 8 mins on the 2,200, if you need extra weight in the
nose then a bigger battery is the answer. I have some 4 cell 3,300 LiPo's which we could do some balance & power / prop tests with.
Trust this helps.

I wasn't able to check the HK website earlier (school server block), but there are three different G46 motors and two different G32's. Looking at the recommended setups, you would need to make sure you ordered the 670kV G46 or the 600kV G32. The lower kV versions of these motors will probably need a very big prop which won't look right and might even cause ground clearance issues.

I think the G46 is far too much for this model also regardless of kv ratings. The G32 is your best bet using the battery pack weight to balance. I have a couple of new G32's here of 770kv bought to upgrade the Twin Otter. Max power was approx 600 watts (41 amps). If your model weighs in at your estimates that's nearly 90 watts per pound.

On a 4 cell you should be okay with 12 inch prop.

Phil - If you want to try one or buy one they are here. I have no need now as I have uprated the Twotter with different props and lipos.

Or, I could put a 40 FS in it.

But then it would get all clarted up and getting it out of the open structure would be a pain, so electric for me.

Thanks for the advice and offers, lads: I may well be taking you up. I have commenced the fus, but have little to show as yet apart from two flat side frames. After tomorrow, I may have something to play with, for balance and equipment layout. I could take a bay off the end of the looong fuselage. Apparently some of the 900 plus aircraft built to the Mk XI design were shorter than the one Wot flew the channel.

The maximum ground clearance is 8-1/2" and from snaps of other models and full size examples, something around 11-1/2" or 12" would look the right size, so the G46 670 kv matches (recommended 12x8 minimum). The G32 600 kv mentions 13x4 to 14x10.

This is much more fun that faffing with fuel...

You gotta be joking....... :whistle:

Still think a G32 770kv is what you need. Swinging props in the range 11x7 - 12x8. On three cells gave approx 440 watts on the 12x8. An example: 2 x 440 watts got my Twin otter (10+lbs) in the air easily. My reckoning is a G32 on four cells will probably want 12 inch prop and give you around 600 watts. Obviously a Watt Meter will help here on getting the best out of it. A 46 is quite a lump, think of those motors in the WOT trainers which are very similar.
