This looks good. Plan to buy this in my next shopping Title: Re: Need an adequate motor for a F-22 raptor Post by: ujjwaana on April 06, 2011, 05:48:55 PM I am myself building a 28" Tomhe F-22 after building (and crashing) 18" scale down one. I am gonna use the below motor from HK :
http://www.hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=7993 this provides 800+g of thrust at 35+ Amp. should be just adequate for your 32" F-22, which I guess would have AUW of 600+ g. Or from RcforallIn http://cgi.ebay.in/RCFORALL-BRUSHLESS-OUTRUNNER-MOTOR-A2217K-4-A-2836-4-/110655167688?pt=LH_DefaultDomain_203&hash=item19c38fdcc8#ht_2386wt_868 Put a 6x4 sports propeller (not thin GWS props) and use a Prop adapter , not prop saver. I have not seen bigger outrunner 2200kv motors than these. Avoid inrunners as they are not as efficient as outrunners , giving lesser flight time.

I have cleared lot of doubts because of your post.. By the way .. Pankaj verma had just put a 2200 kv motor for sale @ 650 rs. . I have already blocked it.. Regards Viraj Title: Re: Need an adequate motor for a F-22 raptor Post by: pankaj on April 06, 2011, 06:02:20 PM I have not used this on F-22 ,but the reviews on HK says that it is good enough for f-22 .

Wow !! when did this motor HK add ? This motor looks exactly the same ad DYS Motor sold by Rcforall and those sold by RCTimers.com : http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=127&productname=http://www.hobbyking.com/hobbyking/store/product_reviews.asp?idproduct=12919 great that you booked the motor Viraj. All the best for the build. Dont forget to reinforce the front nose part and base of of fuse-box which takes much of the beating. Put fiber tape on all leading edges . Title: Re: Need an adequate motor for a F-22 raptor Post by: viraj on April 07, 2011, 11:13:42 AM Sure ujjwaana
will put fibre tape on leading edges.. I am making it using a 5mm Biofoam .. do i need to make the nose of 10 mm (I read it somewhere to glue the 2 nos 5mm cutouts together to stregthen it) or 5mm is good enough.. .. need to know the electrical connections setting.. cause i always wonder if i connect the servos to the tailerons channel and how will it also work as ailerons as well .. ??? ??? |
